Abstract
Description
Technical Field
[0001] The present invention relates to a method for inhibiting acetyl-CoA synthetase short-chain 2 (ACSS 2 ) protein. Thus, the small molecules can be used to treat diseases such as cancer, cardiac disorders, metabolic disorders, neurological disorders, fibrotic diseases, aging disorders, bacterial and viral infections, etc. The present invention extends to pharmaceutical compositions of the compounds themselves, methods for preparing the compounds, and methods for inhibiting ACSS 2 Protein method. Background Art
[0002] Acetyl CoA synthetase (ACSS 1-3 ) family of cellular enzymes that complete the first enzymatic step by linking acetate to CoA in an ATP-driven process, converting acetate to the multifunctional metabolite acetyl-CoA (Knowles, SE; Jarrett, IG; Filsell, OH; Ballard, FJ, Biochem. J., 1974, 142 ,401-411). ACSS 1 and ACSS 3 ACSS is mainly expressed in the mitochondria of cells. 2 Expressed in both the nuclear compartment and the cytoplasmic compartment (Fujino, T.; Kondo, J.; Ishikawa, M.; Morikawa, K.; Yamamoto, TT, J. Biol. Chem., 2001, 276 ,11423-11426; Luong, A.; Hannah, VC; Brown, MS; Goldstein, JL, Journal of Biological Chemistry, 2000, 275 , 26458-26466; Ariyannur, PS; Moffett, JR; Madhavarao, CN; Arun, P. et al., Journal of Comparative Neurology (J. Comp. Neurol.), 2010, 518 ,2952-2977).
[0003] Acetyl CoA plays a central role in cellular metabolism and is involved in multiple cellular processes (Pietrocola, F.; Galluzzi, L.; Bravo-San Pedro, JM, et al., Cell. Metab., 2015, 21 , 805-821). In well-fed mammalian cells, acetyl CoA enters the citric acid cycle by condensing with oxaloacetate to form citrate and, from this, a variety of other metabolites (Srere, PA, J. Biol. Chem., 1959, 234 , 2544-2547). It is a key intermediate in carbon sources and a basic building block for the synthesis of fatty acids, amino acids and sterols.
[0004] Cell growth and proliferation are closely related to metabolism and acetyl CoA availability. One of the hallmarks of cancer is rapid, uncontrolled cell proliferation, which requires the production of increased energy and biomass by ATP and lipid production. This relates to changes in both the capture mode of extracellular nutrients and its metabolic mode. The strategy of increasing metabolic rate and enhancing proliferation capacity adopted by targeted cancer cells under conditions of limited nutrients is an attractive anticancer treatment. It especially forces the source of the key cytoplasmic regulator (i.e. acetyl CoA) of the synthetic targeting lipids, cholesterol and amino acids.
[0005] In nutrient-limited conditions (e.g., in cancer cells), aerobic glycolysis occurs and pyruvate formed from glucose metabolism is preferentially converted to lactate by reduction rather than used to synthesize acetyl CoA (the "Warburg Effect"). In response, acetate uptake and ACSS 2 Both were upregulated and there was a significant shift in obtaining acetyl-CoA from other nutrients, a critical dependence on ACSS 2 to synthesize acetyl CoA.
[0006] Acetate is absorbed and metabolized into biomass by lipid-depleted proliferating hypoxic tumor cells (Corbet, C.; Feron, O., Curr. Op. Clin. Nutr. Metab. Care, 2015, 18 , 346-353). For more than a decade, the propensity of certain tumors to take up acetate has been used to detect primary tumors and identify distant metastases, using 11C-acetate-guided positron emission tomography (PET) imaging is used to detect or grade metastases in patients with glioma, hepatocellular carcinoma, non-small cell lung cancer, and prostate cancer. This reinforces the conclusion of earlier studies that tumor cells often take up large amounts of acetate as a nutrient in preference to glucose to meet their increased acetyl-CoA requirements (Yoshimoto, M.; Waki, A.; Yonekura, Y.; Sadato, N. et al., Nucl. Med. Biol., 2001, 28 ,117-122).
[0007] There is growing clinical evidence that acetate and ACSS 2 Located at a key metabolic node in tumor cells. Genome analysis revealed that ACSS 2 Copy number is associated with higher and more aggressive stages of breast cancer and metastatic prostate cancer (Schug, ZT; Peck, B.; Jones, DT; Zhang, Q.; Grosskurth, S. et al., Cancer Cell, 2015, 27 ,57-71). Compared with those who exhibited small or no ACSS 2 Expression of matched normal specimens was compared using anti-ACSS 2 The antibody showed significant expression in immunohistochemical analysis (IHC) performed on human breast, ovarian, kidney and lung tumor specimens. Patients with grade 2 / 3 glioma (Mashimo, T.; Pichumani, K.; Vemireddy, V.; Hatanpaa, KJ, Cell, 2014, 159 , 1603-1614) or triple-negative breast cancer (Comerford, SA; Huang, Z.; Du, X.; Wang, Y. et al., Cell, 2014, 159 ,1591-1602) revealed that high ACSS 2 These clinical findings show that acetate uptake, ACSS 2 There is a strong correlation between ACSS expression and cancer progression. This suggests that inhibition of ACSS 2 Activity may benefit patients with acetate-metabolizing tumors.
[0008] Hypoxic tumor cells express high levels of cytoplasmic ACSS 2 Knockdown of ACSS in tumor cells by RNA interference 2 It can enhance tumor cell death under long-term hypoxia in vitro and slow tumor growth in vivo (Yoshii, Y.; Furukawa, T.; Yoshii, H.; Mori, T. et al., Cancer Sci., 2009, 100 ,821-827), thus confirming that ACSS 2 The role of ACSS in tumor progression and provides a rationale for pharmacological inhibitors. 2 Interfering with acetate metabolism through activation would deprive resilient tumor cells of a key nutrient source and could arrest or terminate the growth of refractory tumors.
[0009] ACSS 2 Donates acetyl CoA to histone acetyltransferase to acetylate lysine residues on histones (Takahashi, H.; McCaffery, JM; Irizarry, RA; Boeke, JD, Mol. Cell, 2006, 23 , 207-217) and thereby regulate the transcription of growth genes by epigenetically modifying chromatin (Kaelin, WG; McKnight, SL, Cell, 2013, 153 , 56-69). Aberrant chromatin regulation can affect different cellular processes that depend on acetylation (e.g., glucose homeostasis, neuronal gene transcription, autophagy, and mitochondrial respiration) and is associated with pathologies such as neurodegeneration, neurological disorders, immune deficiencies, and metabolic diseases (Mirabella, AC; Foster, BM; Bartke, T., Chromosoma, 2016, 125 , 75-93). Given the extent to which cancer cells utilize metabolic adaptations to meet their elevated energy and biomass demands, it has been proposed that cancer cells may also produce major changes in their epigenetic footprint to favor tumor growth and survival (Lu, C.; Thompson, CB, Cell Metabolism, 2012, 16 ,9-17).
[0010] The heterodimeric stress-responsive transcription factor hypoxia-inducible factor 2α (HIF-2α) is regulated by acetylation of Creb binding protein (CBP), which in turn generates acetyl-CoA (via ACSS) 2 ) regulation (Chen, R.; Xu, M.; Nagati, JS; Hogg, RT; Das, A. et al., PLoS One, 2015, 10 ,e0116515). Knockdown of ACCS in tumor cells 2 Expression of HIF-2α or HIF-2α impaired cell proliferation, cell migration and invasion during hypoxia and resulted in a significant reduction in tumor burden in mice bearing HT1080 flank tumors.
[0011] ACSS 2 It is post-translationally modified by the NAD-dependent deacetylase sirtuin. Sirtuins play a central role in energy homeostasis and aging and have been proposed to regulate ACSS. 2 and acetate metabolism may also play a central role in aging (Shimazu, T.; Hirschey, MD; Huang, Y.; Ho, LTY; Verdin, E., Mech. Ageing Develop., 2010, 131 ,511-516).
[0012] The etiology of aging is multifactorial but manifests as a gradual decline in metabolic performance. As individuals age, there is an accumulation of cellular damage and changes in endogenous repair and detoxification processes. Healthy aging depends on the effective removal of damaged cellular material, which is mediated in part by autophagy (Eisenberg, T.; Schroeder, S.; Andryushkova, A. et al., Cell Metabolism, 2014, 19 , 431-444). Knockdown of ACCS in mammalian cells 2 It can strongly induce autophagy and maintain lifespan, while nutrient starvation of cells achieves the same effect (Marino, G.; Pietrocola, F.; Ischberg, T.; Kong, Y., et al., Molecular Cell, 2014, 53 ,710-725).
[0013] Human cytomegalovirus (HCMV) induces a steady increase in lipid synthesis to increase the chances of productive infection. 2 In knockout human fibroblasts, both HCMV-induced lipid production and viral growth were significantly reduced compared with normal controls (Vysochan, A.; Sengupta, A.; Weljie, AM; Alwine, JC; Yu, Y.), PNAS, 2017, 114 ,E1528-E1535), which indicates damage to ACSS 2 It may be useful as an antiviral therapy for some types of infections.
[0014] Martinez-Micaelo et al. have shown that ACSS 2 It is a nutrient sensing protein and a key regulator of metabolic homeostasis (Martinez-Micaelo, N.; Gonzalez-Abuin, N.; Terra, X.; Ardevol, A.; Pinent, M., et al., Disease Mod. Mechan., 2016, 9 ,1231-1239). ACSS 2 Gene expression correlates with hepatic concentrations of TCA-related metabolites and plasma levels of glucose. Phosphoprotein analysis in mice fed a high-fat diet (Shaik, AA; Qiu, B.; Wee, S.; Choi, H. et al., Nature, 2016, 6 , 25844) showed that several enzymes involved in lipid and glucose homeostasis underwent a series of phosphorylation changes (including ACSS 2 Huang et al. observed that in a diet-induced obesity model, knockdown of ACSS 2 After the treatment, the body weight and hepatic sebaceous gland disease were significantly reduced. 2 Deficiency appears to reduce dietary lipid absorption and lipid transport to the liver (Huang, Z.; Zhang, M.; Plec, AA; Estill, SJ, et al., PNAS, 2018, 115 , E9499-E9506) and controls systemic lipid metabolism according to acetate availability. These studies indicate that ACSS 2Selective inhibitors of β-lactamase may have therapeutic benefit in obesity and fatty liver disease.
[0015] This evolving knowledge has inspired the development of ACSS 2 Numerous studies have been conducted on the possible therapeutic applications of inhibition.
[0016] Therefore, there remains a need for improved therapies for treating diseases that may be difficult to treat using traditional treatment modalities, such as cancer, neurological disorders, and metabolic disorders. There is a need to develop improved compositions and methods in this area. In particular, there is a need to inhibit human ACSS 2 Protein compounds and methods of treating diseases that may benefit from such modulation. Summary of the invention

[0088] The complex of the compound of formula (I) can be understood as a multi-component complex, in which the drug and at least one other component are present in stoichiometric or non-stoichiometric amounts. The complex may not be a salt or a solvate. Such complexes include clathrates (drug-host incorporated into the complex) and co-crystals. The latter is generally defined as a crystalline complex of neutral molecular components, which are bound together by non-covalent interactions, but can also be a complex of neutral molecules and salts. Co-crystals can be prepared by melt crystallization, recrystallization from a solvent, or physical grinding of the components together, see Chem Commun, 17, 1889-1896, O. Almarsson and MJ Zaworotko (2004), which are incorporated herein by reference. For a general review of multi-component complexes, see J Pharm Sci, 64 (8), 1269-1288, Haleblian (August 1975), which are incorporated herein by reference.
[0089] The term "pharmaceutically acceptable salt" is understood to refer to any salt of the compounds provided herein that retains its biological properties and is non-toxic or otherwise desirable for pharmaceutical use. The salts may be derived from various organic and inorganic counterions well known in the art. The salts include, but are not limited to: (1) acid addition salts formed using organic or inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, sulfamic acid, acetic acid, adipic acid, tartaric acid, trifluoroacetic acid, trichloroacetic acid, propionic acid, hexanoic acid, cyclopentylpropionic acid, glycolic acid, glutaric acid, pyruvic acid, lactic acid, malonic acid, succinic acid, sorbic acid, ascorbic acid, malic acid, maleic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, 3-(4-hydroxybenzoyl)-1-hydroxybenzoyl ... )benzoic acid, picric acid, cinnamic acid, mandelic acid, phthalic acid, lauric acid, methanesulfonic acid, ethanesulfonic acid, 1,2-ethane-disulfonic acid, 2-hydroxyethanesulfonic acid, benzenesulfonic acid, 4-chlorobenzenesulfonic acid, 2-naphthalenesulfonic acid, 4-toluenesulfonic acid, camphoric acid, camphorsulfonic acid, 4-methylbicyclo[2.2.2]-oct-2-ene-1-carboxylic acid, glucoheptonic acid, 3-phenylpropionic acid, trimethylacetic acid, tert-butylacetic acid, lauryl sulfuric acid, gluconic acid, benzoic acid, glutamic acid, hydroxy or (2) base addition salts formed when an acidic proton present in the parent compound is (a) replaced by a metal ion (e.g., an alkali metal ion, an alkaline earth ion, or an aluminum ion) or an alkali metal or alkaline earth metal hydroxide (e.g., sodium, potassium, calcium, magnesium, aluminum, lithium, zinc, and barium hydroxides), ammonia, or (b) coordinated with an organic base such as an aliphatic, alicyclic, or aromatic Aromatic organic amines (e.g., ammonia, methylamine, dimethylamine, diethylamine, picoline, ethanolamine, diethanolamine, triethanolamine, ethylenediamine, lysine, arginine, ornithine, choline, N,N′-dibenzylethylenediamine, chloroprocaine, diethanolamine, procaine, N-benzylphenethylamine, N-methylglucamine, piperazine, succinimidylamine, tetramethylammonium hydroxide, and the like).
[0090] Pharmaceutically acceptable salts may include sodium, potassium, calcium, magnesium, ammonium, tetraalkylammonium and the like, and, when the compound contains a basic functional group, salts of nontoxic organic or inorganic acids such as hydrohalides (e.g., hydrochlorides, hydrobromides and hydroiodides), carbonates or bicarbonates, sulfates or bisulfates, borates, phosphates, hydrogen phosphates, dihydrogen phosphates, pyroglutamate, glucarates, stearates, sulfamates, nitrates, orotates, oxalates, palmitates, pamoates, acetates, trifluoroacetates, trichloroacetates, propionates, hexanoates, cyclopentylpropionates, glycolates, glutarates, pyruvates, lactates, malonates, succinates, tannates, tartrates, toluenesulfonates, sorbates, ascorbates, malates, maleates, fumarates, tartrates, camphorsulfonates, citrates, cyclamates, benzoates, isethionates, ethanesulfonates, formates, 3-(4-hydroxybenzoate)-4-nitropropionates, 1,2-dihydro-1,2-dihydro-1,2-dihydro-1,2-dihydro-1,2-dihydro-1,2-dihydro-1,2-dihydro-1,2-dihydro-1,2-dihydro-1,2-dihydro-1,2-dihydro-1,2-dihydro-1,2-dihydro-1,2-dihydro-1,2-dihydro-1
[0013] The invention also includes but is not limited to the following: benzoate, picrate, cinnamate, mandelate, phthalate, laurate, methanesulfonate (mesylate), methylsulfate, naphthoate, 2-naphthoate, nicotinate, ethanesulfonate, 1,2-ethane-disulfonate, 2-hydroxyethanesulfonate, benzenesulfonate (benzenesulfonate, besylate), 4-chlorobenzenesulfonate, 2-naphthalenesulfonate, 4-toluenesulfonate, camphorate, camphorsulfonate, 4-methylbicyclo[2.2.2]-oct-2-ene-1-carboxylate, glucoheptonate, 3-phenylpropionate, pivalate, tert-butylacetate, lauryl sulfate, glucoheptonate, gluconate, glucuronate, hexafluorophosphate, hydroxybenzoate, benzoate, glutamate, hydroxynaphthoate, salicylate, stearate, cyclohexylsulfamate, quinate, muconate, hydroxynaphthoate and the like.
[0091] Hemi-salts of acids and bases may also be formed, for example hemi-sulfates.
[0092] Those skilled in the art will appreciate that the above salts include those in which the counter ion is optically active (eg, D-lactate) or a racemate (eg, DL-tartrate).
[0093] For a review of suitable salts, see "Handbook of Pharmaceutical Salts: Properties, Selection, and Use", Stahl and Wermuth (Wiley-VCH, Weinheim, Germany, 2002).
[0094] Pharmaceutically acceptable salts of compounds of formula (I) can be prepared by one or more of the following three methods:
[0095] (i) by reacting a compound of formula (I) with a desired acid or base;
[0096] (ii) by removing an acid or base labile protecting group from a suitable precursor of a compound of formula (I) using an acid or base as required; or
[0097] (iii) by converting one salt of a compound of formula (I) into another salt by reaction with a suitable acid or base or with the aid of a suitable ion exchange column.
[0098] All three reactions are usually carried out in solution. The resulting salt may precipitate and be collected by filtration, or may be recovered by evaporation of the solvent. The degree of ionization of the resulting salt may vary from fully ionized to almost non-ionized.
[0099] The term "solvate" is understood to refer to a provided compound or salt thereof, which further includes a stoichiometric or non-stoichiometric amount of a solvent bound by non-covalent intermolecular forces. If the solvent is water, then the solvate is a hydrate. Pharmaceutically acceptable solvates of the present invention include those in which the solvent of crystallization may be isotopically (e.g., D 2 O,d 6 -acetone and d 6 -DMSO) substituted.
[0100] The currently accepted classification system for organic hydrates is that which defines isolated site, channel or metal ion coordinated hydrates, see Polymorphism in Pharmaceutical Solids, KR Morris (HG Brittain, ed., Marcel Dekker, 1995), which is incorporated herein by reference. Isolated site hydrates are those in which the water molecules are separated from each other by intervening organic molecules and are not in direct contact. In channel hydrates, the water molecules are located in the lattice channels, where they are adjacent to other water molecules. In metal ion coordinated hydrates, the water molecules are bonded to the metal ion.
[0101] When the solvent or water is tightly bound, the complex will have a well-defined stoichiometry that is independent of humidity. However, when the solvent or water is weakly bound, such as in channel solvates and hygroscopic compounds, the water / solvent content will depend on humidity and drying conditions. In such cases, non-stoichiometry will be normal.
[0102] The compounds of the present invention may exist in a continuum of solid states ranging from completely amorphous to completely crystalline, including polymorphs of the crystalline material. The term "amorphous" refers to a state in which a material lacks long-range order at the molecular level and can exhibit physical properties of a solid or a liquid depending on the temperature. Typically, the material does not produce a characteristic X-ray diffraction pattern, and it is more formally described as a liquid when it exhibits solid properties. Upon heating, a change from solid to liquid properties occurs, characterized by a change of state, typically a secondary change ("glass transition"). The term "crystalline" refers to a solid phase in which a material has a regular, ordered internal structure at the molecular level and produces a characteristic X-ray diffraction pattern with defined peaks. Upon sufficient heating, the material will also exhibit a liquid form, but the change from solid to liquid is characterized by a phase transition, typically a primary phase transition ("melting point").
[0103] The compounds of the invention may also exist in a mesomorphic state (mesophase or liquid crystal) when subjected to suitable conditions. The mesomorphic state is an intermediate state between a true crystalline state and a true liquid state (melt or solution). Mesomorphism due to temperature changes is described as "thermotropic liquid crystals" and mesomorphism due to the addition of a second component (e.g. water or another solvent) is described as "lyotropic liquid crystals". Compounds with the potential to form lyotropic mesophases are described as "amphiphilic" and are characterized by having an ionic polar head group (e.g. -COO - Na + 、-COO - K + or -SO 3 - Na + ) or a nonionic polar head group (e.g. -N - N + (CH 3 ) 3 ) molecular composition. For more information, see Crystallography and Polarizing Microscopy ( Crystals and the Polarizing Microscope ), NH Hartshorne and A. Stuart, 4th edition (Edward Arnold, 1970), which is incorporated herein by reference.

[0135] The compounds of formula (I) may contain one or more stereogenic centers and may therefore exist in the form of optical isomers (eg enantiomers and diastereomers). All such isomers and mixtures thereof are included within the scope of the present invention.
[0136] Stereocenters can occur in groups R and R 1 -R 9 In any one of .
[0137] It should be understood that the above compounds can exist in the form of enantiomers and diastereoisomer pairs. These isomers also represent other embodiments of the present invention.
[0138] Conventional techniques for the preparation / isolation of individual enantiomers include chiral synthesis from a suitable optically pure precursor or resolution of the racemate (or the racemate of a salt or derivative) using, for example, chiral high pressure liquid chromatography (HPLC).
[0139] Alternatively, the racemate (or racemic precursor) may be reacted with a suitable optically active compound (e.g., an alcohol) or, in the case where the compound of formula (I) contains an acidic or basic moiety, a base or acid (e.g., 1-phenylethylamine or tartaric acid). The resulting diastereomeric mixture may be separated by chromatography and / or fractional crystallization and one or both of the diastereomers converted to the corresponding pure enantiomer by means well known to those skilled in the art.
[0140] The chiral compounds of the present invention (and chiral precursors thereof) can be obtained in an enantiomerically enriched form using chromatography, typically HPLC on an asymmetric resin using a mobile phase consisting of a hydrocarbon, typically heptane or hexane, containing 0 to 50% by volume, typically 2% to 20% isopropanol and 0 to 5% by volume of an alkylamine, typically 0.1% diethylamine. Concentrating the eluate can yield an enriched mixture.
[0141] Stereoisomeric mixtures can be separated by conventional techniques known to those skilled in the art; see, for example, "Stereochemistry of Organic Compounds", EL Eliel and SH Wilen (Wiley, New York, 1994).

[0292] Linkers are known to those skilled in the art in the form of "stable" linkers, which resist degradation in the cell and in the systemic circulation, or "cleavable" or "conditionally unstable" linkers, which are designed to degrade under intracellular conditions and / or in the systemic circulation following a defined triggering event, which may be a pH change or a metabolic process such as ester or amide hydrolysis. The conjugates of the invention may comprise two or more cleavage mechanisms, which may be selected from acid-induced cleavage, peptidase-induced cleavage (e.g., peptide linkers cleaved by intracellular proteases such as lysosomal or endosomal proteases, see Trout et al., 1982, PNAS USA, 79, 626-629), esterase-induced cleavage, glycosidase-induced cleavage, glucuronidase-induced cleavage, phosphodiesterase-induced cleavage, phosphatase-induced cleavage, lipase-induced cleavage, or disulfide bond cleavage. Certain intracellular compartments, such as endosomes and lysosomes, have an acidic pH (pH 4.5) and provide conditions suitable for cleavage of acid-labile linkers. Specific hydrolysis processes have been described, such as the protease cleavage of dipeptides (e.g., valine-citrulline dipeptide moiety) contained in the clinical precedent ADC brentuximab vedotin (Ducry et al., Bioconj. Chem., 2010, 21, 5-13), phenylalanine-lysine dipeptide, maleimidocaproyl or maleimidocaproyl-valine-citrulline linkers. The p-aminobenzyloxycarbonyl (PABC) radical from the digestive group can also form part of the linker structure, which is eliminated from the conjugate in response to a suitable triggering event to release the parent structure (Carl et al., J. Med. Chem., 1981, 5). 24 ,479 and Chakravarty et al., Journal of Medicinal Chemistry, 1983, 26 , 638), such as in maleimidocaproyl-valine-citrulline-PABC linker. Other linkers include linkers that are cleaved at a specific pH or pH range, such as hydrazones, such as the hydrazone moiety in gemtuzumab-ozogamicin.
[0293] Non-cleavable linkers may be insensitive to proteases. Non-cleavable linkers include those contained in the clinical precedent ADC trastuzumab emtansine and require intracellular degradation of the conjugate to release the active drug C. See, e.g., Wong, Chemistry of Protein Conjugation and Cross-Linking, CRC Press Inc., Boca Raton, 1991.
[0294] The linker may be of a dendritic nature, wherein more than one small molecule C may be covalently linked to the targeting moiety via a branched, multifunctional unit (US2006 / 116422, US2005 / 271615). Dendritic linkers may increase the molar ratio of drug to targeting group, which is related to the efficacy of the conjugate. Thus, in the case where the targeting group contains, for example, only a single thiol group, multiple small molecules may be linked via a dendritic or branched linker.
[0295] The linker can be connected to the targeting moiety T by a reactive group thereon at any suitable available position on the targeting moiety in various ways. Examples of suitable reactive groups include surface lysine, oxidized carbohydrates and cysteine residues. Suitable reactive groups are known to those skilled in the art. For example, various antibody-drug conjugate (ADC) bonding techniques are known in the industry, including by alkylation, reductive amination, transesterification, amidation and thiol Michael addition (Michael addition). The resulting linkage includes functional groups based on hydrazone, disulfide, maleimide, succinimide and peptide. For example, a thiol group or a cysteine residue can be bonded to a linker or a spacer group by a maleimide group. Alternative coupling chemistries include lysine reactive groups such as succinyl or HOBt esters, pentafluorophenyl esters, β-lactams, isocyanates, and isothiocyanates; azide reactive groups such as alkynes and strained alkynes; cysteine reactive groups such as maleimide, α-haloacetamide, pyridyl disulfide, and vinyl sulfoxide; and ketone reactive groups such as hydroxylamine, hydrazine, and acyl hydrazide.
[0296] In some embodiments, the number of drug / linker moieties conjugated per antibody molecule is between 1 and 10. The drug-antibody ratio (DAR) is typically 1 to 10, and may be 2 to 5 or 2 to 3. Thus, b may be 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10.
[0297] The conjugates can be designed to specifically target certain cell types or tumor types via the targeting moiety. Thus, the targeting moiety can be configured to direct the compound of formula (I) to specific cells or tumor types and thereby deliver the STING modulator in a cell-specific manner. The conjugates can thus be used accordingly in therapeutic settings. It is known to those skilled in the art that the principle of this targeted delivery is closely related to ADC technology, for example, as described in Polakis P., Pharmacological Reviews, 2016, 68 , 3-19 and Beck et al., Nature Reviews: Drug Discovery (Nat. Revs. Drug Disc.), 2017, 16 , 315-337. The conjugate can then be taken up inside the cell or tumor by receptor-mediated endocytosis. The target antigen or receptor may be part of a cell or tumor or may be an extracellular matrix protein within the cell or tumor microenvironment. Once inside the cell or tumor, one or more specific peptide sequences within the conjugate can be hydrolytically cleaved by one or more cell or tumor proteases. For example, tumor-associated proteases, cathepsins B, C or D or plasmin proteases can cleave the linker and release the active compound in the target cell or target cell tumor microenvironment. The active drug then migrates freely within the cell or microenvironment and thereby contacts and subsequently regulates the STING protein. In some embodiments, the active drug can be cleaved from the targeting portion outside the cell or tumor and the active drug then acts on the cell surface or penetrates the cell or tumor.
[0298] T is a targeting moiety and may include an antibody, antibody fragment, nucleic acid-based molecule, carbohydrate, peptide, modified peptide, or small molecule.
[0299] In one embodiment, T can be configured to target a tumor antigen. Thus, T cells can be configured to target human epidermal growth factor receptor (EGFR), plasminogen activator, cytotoxic T lymphocyte-associated antigen (CTLA) (e.g., CTLA-4), vascular endothelial growth factor (VEGF), neurotrophic factors (e.g., BDNF), fibroblast growth factor receptor (FGFR), nerve growth factor, platelet-derived growth factor (PDGF), transforming growth factor (TGF), tissue factor (TF), EpCAM, CEACAM5, CEACAM6, colon-specific antigen p, FLT3, PSA, PSMA, PSCA, STEAP, BCMA, CEA, folate receptor, cathepsin D, estrogen receptor, progesterone receptor, NCA-95, NCA-90, A3, A33, Ep-CAM, CD33 / CD30 / CD37 / CD52 / CD66e, CD56 / CD74 / CD79 / CD22 receptor, SLC34A2 gene product, SLC44A4, mesothelin protein, integrin alphaV β3, PD-1, PD-L1, EGP-1, EGP-2, EphA2 tyrosine kinase, mucin cell surface antigens (e.g., MUC16), hLewis Y antigen, carbonic anhydrase IX, 5T4, EFNA4, DLL4, Axl, B7, ALK, Fyn3, HLA, HIF, IGF, CC49, AFP, NaPi2b, brc-abl, caspase-8, guanylyl cyclase C, CD19, CD20, CD21, CD22, CD40, CD79a, CD79b, CD98, CD123, PTK7, CDK4, RANTES, CD44 、CD48、CD133、CD70、CD72、CD74、CD166、c-kit、cMet、ErbB2 / Her2、ErbB3 / Her3、ErbB4 / Her4、OX40、p53、α-fetoprotein、R1、PAP、PAX3、PAX5、Ras、Rho、ROR2、Connexin-4、E-cadherin、P-cadherin、cadherin-6、LRRC15、BMPR1B、E16、Sema 5b, ETBR, MSG783, Trop2, TRPM4, ENPP3, SLITRK6, LIV-1, CRIPTO, FcRH1, IRTA2, TENB2, FcRH2, NCA, MDP, IL30Rα, ERK, gpNMB, LYPD3, GEDA, CXCR5, HLA-DOB, P2X5, LY64 or LY75.
[0300] In a preferred embodiment, T is configured to target Her2. It is understood that HER2 may also be referred to as Erbb2 and is a biomarker for breast cancer, gastric cancer, ovarian cancer, and / or lung cancer.
[0301] In a preferred embodiment, T is an antibody or a fragment thereof. Certain antibodies have previously been used in the field of immuno-oncology. Exemplary anti-PD1 antibodies include lambrolizumab (MK-3475, Merck), nivolumab (BMS-936558, Bristol-Myers Squibb), AMP-224 (Merck) and pidilizumab (CT-011, Curetech Ltd.). Known anti-PDL1 antibodies include MDX-1105 (Medarex), MEDI4736 (Medimmune), MPDL4280A (Genentech) and BMS-936559 (Bristol-Myers Squibb). Exemplary anti-CTLA4 antibodies include ipilimumab (Yervoy, Bristol-Myers Squibb) and tremelimumab (Pfizer). Exemplary anti-ErbB2 / Her2 antibodies include trastuzumab (Roche), pertuzumab (Genentech), margetuximab (Macrogenics) and HT-19 (Mersana Therapeutics). In a preferred embodiment, T is trastuzumab or a fragment or derivative thereof.
[0302] As an example, a conjugate comprising an anti-HER2 antibody can specifically target HER2-positive cancer cells or tumors. Trastuzumab (Herceptin or Herclon) is a humanized monoclonal antibody that binds to the membrane-proximal portion of the extracellular domain of the HER2 receptor (Hudis et al., N. Engl. J. Med., 2007, 357 , 39-51; Cho et al., Nature, 2003, 421 Trastuzumab was approved by the USFDA in September 1998 for the treatment of metastatic breast cancer in patients whose tumors overexpress HER2 and who have received one or more chemotherapy regimens for metastatic disease.
[0303] The invention extends to whole antibodies as well as antigen-binding fragments or regions of corresponding full-length antibodies.
[0304] Antibodies or their antigen-binding fragments may be monovalent, divalent or multivalent. A monovalent antibody is a dimer (HL) comprising a heavy chain (H) and a light chain (L) associated by a disulfide bridge. A divalent antibody is a tetramer (H2L3) comprising two dimers associated by at least one disulfide bridge. Multivalent antibodies may also be produced, for example, by connecting multiple dimers. The basic structure of an antibody molecule consists of two identical light chains and two identical heavy chains, which are associated in a non-covalent manner and may be connected by disulfide bonds. Each heavy chain and light chain contains an amino-terminal variable region of about 110 amino acids, and the rest of the chain is a constant sequence. The variable region includes several hypervariable regions or complementary determining regions (CDRs), which form the antigen binding site of the antibody molecule and determine its specificity for the antigen or its variants or fragments (e.g., epitopes). On either side of the CDRs of the heavy and light chains is a framework region, which is a relatively conservative amino acid sequence that anchors and directs the CDRs. The antibody fragment may comprise a bispecific antibody (BsAb) or a chimeric antigen receptor (CAR).
[0305] The constant region consists of one of five heavy chain sequences (μ, γ, ζ, α or ε) and one of two light chain sequences (κ or λ). The heavy chain constant region sequence determines the antibody isotype and the effector function of the molecule.
[0306] Preferably, the antibody or antigen-binding fragment thereof is isolated or purified.
[0307] In a preferred embodiment, the antibody or antigen-binding fragment thereof comprises a polyclonal antibody or antigen-binding fragment thereof. The antibody or antigen-binding fragment thereof can be generated in rabbits, mice or rats.
[0308] In another preferred embodiment, the antibody or its antigen-binding fragment comprises a monoclonal antibody or its antigen-binding fragment. Preferably, the antibody is a human antibody. As used herein, the term "human antibody" may mean an antibody (e.g., a monoclonal antibody) comprising heavy chain and light chain CDR amino acid sequences substantially identical to those found in a specific human antibody exhibiting immunospecificity. When compared to a reference sequence, an amino acid sequence substantially identical to a heavy chain or light chain CDR exhibits considerable sequence identity. The identity is clearly known or identified as an amino acid sequence representing a specific human antibody. In fact, the same heavy chain and light chain CDR amino acid sequences may have, for example, minor amino acid modifications or conservative amino acid substitutions.
[0309] The term "human monoclonal antibody" may include monoclonal antibodies with substantially or completely human CDR amino acid sequences, for example, produced by recombinant methods, such as by phage libraries, by lymphocytes, or by hybridoma cells.
[0310] The term "humanized antibody" may refer to an antibody from a non-human species (eg, mouse or rabbit) whose protein sequence has been modified to increase its similarity to antibodies naturally produced in humans.
[0311] The antibody may be a recombinant antibody. The term "recombinant human antibody" may include human antibodies produced using recombinant DNA technology.
[0312] The term "antigen binding region" may refer to a region of an antibody that has specific binding affinity for its target antigen or a variant or fragment thereof. Preferably, the fragment is an epitope. The binding region may be a hypervariable CDR or a functional portion thereof. The term "functional portion" of a CDR may refer to a sequence within a CDR that exhibits specific affinity for a target antigen. A functional portion of a CDR may include a ligand that specifically binds to a target antigen or a fragment thereof.
[0313] The term "CDR" may refer to the hypervariable regions in the heavy and light variable chains. There may be one, two, three or more CDRs in each of the heavy and light chains of an antibody. Typically, there are at least three CDRs on each chain that, when configured together, form an antigen binding site, i.e., a three-dimensional combined site that binds or specifically reacts with an antigen. However, it has been hypothesized that there may be four CDRs in the heavy chain of some antibodies.
[0314] The definition of CDR also includes overlaps or subsets of amino acid residues when compared to each other. The exact number of residues that encompass a particular CDR or a functional portion thereof may vary depending on the sequence and size of the CDR. Given the variable region amino acid sequence of an antibody, one skilled in the art can determine the residues that comprise a particular CDR in a conventional manner.
[0315] The term "functional fragment" of an antibody may mean a portion of an antibody that retains functional activity. Functional activity may be, for example, antigen binding activity or specificity. Functional activity may also be, for example, an effector function provided by an antibody constant region. The term "functional fragment" is also intended to include fragments produced, for example, by protease digestion or reduction of human monoclonal antibodies and by recombinant DNA methods known to those skilled in the art. Human monoclonal antibody functional fragments include, for example, individual heavy or light chains and fragments thereof, such as VL, VH and Fd; monovalent fragments, such as Fv, Fab and Fab'; bivalent fragments, such as F(ab'); 2 ; single-chain Fv (scFv); and Fc fragment.
[0316] The term "VL fragment" may refer to a fragment of the light chain of a human monoclonal antibody that contains all or part of the light chain variable region (including CDR). The VL fragment may further contain a light chain constant region sequence.
[0317] The term "VH fragment" may refer to a fragment of the heavy chain of a human monoclonal antibody that contains all or a portion of the heavy chain variable region (including CDR).
[0318] The term "Fd fragment" may refer to the heavy chain variable region coupled to the first heavy chain constant region, that is, VH and CH-1."Fd fragment" does not comprise the second and third constant regions of the light chain or heavy chain.
[0319] The term "Fv fragment" may refer to a monovalent antigen-binding fragment of a human monoclonal antibody, comprising all or part of the variable regions of the heavy and light chains and excluding the constant regions of the heavy and light chains. The variable regions of the heavy and light chains include, for example, CDRs. For example, an Fv fragment comprises all or part of the amino-terminal variable regions of about 110 amino acids in both the heavy and light chains.
[0320] The term "Fab fragment" may refer to a monovalent antigen-binding fragment of a human monoclonal antibody that is larger than an Fv fragment. For example, a Fab fragment comprises the variable region and all or a portion of the first constant domain of the heavy chain and the light chain. Thus, a Fab fragment additionally comprises, for example, amino acid residues about 110 to about 220 of the heavy chain and the light chain.
[0321] The term "Fab' fragment" may refer to a monovalent antigen-binding fragment of a human monoclonal antibody that is larger than a Fab fragment. For example, a Fab' fragment comprises all of the light chain, all of the variable regions of the heavy chain, and all or a portion of the first and second constant domains of the heavy chain. For example, a Fab' fragment may additionally comprise some or all of amino acid residues 220 to 330 of the heavy chain.
[0322] The term "F(ab') 2 Fragment" may refer to a bivalent antigen-binding fragment of a human monoclonal antibody. F(ab') 2 The fragments comprise, for example, all or a portion of the variable regions of two heavy chains and two light chains, and may further comprise all or a portion of the first constant domains of two heavy chains and two light chains.
[0323] The term "single-chain Fv (scFv)" may refer to a fusion of the variable regions of the heavy chain (VH) and the light chain (VL) linked using a short linker peptide.
[0324] The term "bispecific antibody (BsAb)" may refer to a bispecific antibody including two scFvs linked to each other by a shorter linker peptide.
[0325] Those skilled in the art will appreciate that the exact boundaries of an antibody fragment are not important, as long as the fragment maintains functional activity. Using well-known recombinant methods, those skilled in the art can engineer polynucleotide sequences to express functional fragments with any endpoints desired for a particular application. Functional fragments of antibodies may include or consist of fragments having substantially the same heavy and light chain variable regions as human antibodies.
[0326] The antigen-binding fragment thereof may comprise or consist of any fragment selected from the group consisting of: VH, VL, Fd, Fv, Fab, Fab', scFv, F(ab') 2 and Fc fragment.
[0327] Its antigen-binding fragment may include any antigen-binding region sequence of VL, any antigen-binding region sequence of VH, or a combination of VL and VH antigen-binding regions of human antibodies or consist thereof. The appropriate number and combination of VH and VL antigen-binding region sequences can be determined by a person skilled in the art according to the desired affinity and specificity of the antigen-binding fragment and the intended application. Functional fragments or antigen-binding fragments of antibodies can be easily produced and isolated using methods well known to a person skilled in the art. The methods include, for example, proteolytic methods, recombinant methods, and chemical synthesis. Proteolytic methods for isolating functional fragments include using human antibodies as starting materials. Enzymes suitable for proteolysis of human immunoglobulins may include, for example, papain and pepsin. Appropriate enzymes can be easily selected by a person skilled in the art according to, for example, whether monovalent or divalent fragments are required. For example, papain cleavage will produce two monovalent Fab' fragments that bind to the antigen and one Fc fragment. For example, pepsin cleavage will produce a divalent F(ab') fragment. The F(ab') of the present invention can be further reduced using, for example, DTT or 2-mercaptoethanol. 2 fragments to produce two monovalent Fab' fragments.
[0328] Functional or antigen-binding fragments of antibodies produced by proteolysis can be purified by affinity and column chromatography procedures. For example, undigested antibodies and Fc fragments can be removed by binding to protein A. In addition, functional fragments can be purified by charge and size using (human) ion exchange and gel filtration chromatography. Such methods are well known to those skilled in the art.
[0329] Antibodies or antigen-binding fragments thereof can be produced using techniques well known in the art. For example, by recombinant methods (see U.S. Pat. No. 4,816,567), hybridoma technology (Kohler et al., Nature, 1975, 256 , 495), phage display technology (see, for example, Clarkson et al., Nature, 1991, 352,624 and Marks et al., Journal of Molecular Biology, 1991, 222 ,581), synthetic techniques or a combination of such techniques. Preferably, polynucleotides encoding the desired regions of the heavy and light chains of the antibody are first isolated. The regions may include, for example, all or part of the variable regions of the heavy and light chains. Preferably, the regions may particularly include the antigen binding regions, preferably antigen binding sites, and most preferably CDRs of the heavy and light chains.
[0330] The polynucleotides encoding antibodies or antigen-binding fragments thereof of the present invention can be produced using methods known to those skilled in the art. Polynucleotides encoding antibodies or antigen-binding fragments thereof can be directly synthesized by oligonucleotide synthesis methods known in the industry. Alternatively, smaller fragments can be synthesized and joined to form larger functional fragments using recombination methods known in the industry. The antibodies used can be obtained commercially from numerous known sources (e.g., American Type Culture Collection (ATCC, Manassas, Va.)). A large number of antibodies against numerous disease targets and tumor-associated antigens have been deposited at ATCC and / or have disclosed variable region sequences and can be used in the claimed methods and compositions.
[0331] Cysteine engineered antibodies have been designed as Fab antibody fragments (ThioFab) and expressed as full-length IgG monoclonal (thioMab) antibodies (U.S. Pat. No. 7,521,541). ThioFab and ThioMab antibodies have been coupled to the newly introduced cysteine thiols via linkers to prepare site-specific antibody-drug conjugates (U.S. Pat. No. 7,521,541, US2008 / 0050310, WO2008 / 052187).
[0332] Polytherics has described bridging a pair of sulfhydryl groups contained in antibody proteins derived from the reduction of a native disulfide hinge (Badescu et al., Bioconjugate Chemistry, 2014, 25 , 1124-1136) to synthesize homogeneous drug-loaded ADCs. Similar methods have been used by Concortis (U.S. Patent 0105540, April 26, 2015), Thiologics (Schumacher et al., Org Biomol. Chem., 2014, 12 , 7261-7269) and Igenica (Behrens et al., Mol. Pharm., 2015,12 , 3986-3998). Related methods have been described in Frigerio et al., Current Topics in Medicinal Chemistry (Curr. Top. Med. Chem.), 2018, 18 ,1-32.
[0333] Other recent approaches that have been used for targeted homogeneous drug loading of ADCs include incorporating unnatural amino acid groups into antibodies (e.g., selenocysteine (Hofer, T. et al., Biochem., 2009, 48 , 12047-12057) or formylglycine (Drake, PM et al., Bioconjugate Chemistry, 2014, 25 , 1331-1341)). Glycosylation has been used to introduce sialic acid residues at specific sites (Zhou, Q. et al., Bioconjugate Chemistry, 2014, 25 , 510-520), and transglutaminase is used to enzymatically couple the primary amine-containing linker / payload to the glutamate residue (Dorywalska, M. et al., Bioconjugate Chemistry, 2015, 26 , 650-659). These and other methods are described in Sochai AM et al., Biotech. Adv., 2015, 33 ,775-784.
[0334] As used herein, the term "immunospecific" may mean that the binding region is capable of immunoreacting with a target antigen or a variant or fragment thereof by specifically binding thereto. The antibody or antigen-binding fragment thereof may selectively interact with the antigen with an affinity constant of approximately 10 -5 -10 -13 M -1 , preferably 10 -6 -10 -9 M -1 , even more preferably 10 -10 -10 -12 M -1 .
[0335] The term "immunoreact" may mean that the binding region is capable of inducing an immune response when binding to a target antigen or an epitope thereof.
[0336] The term "epitope" may refer to any region of an antigen that is capable of stimulating and combining with the binding region of an antibody or antigen-binding fragment thereof.
[0337] In one embodiment, T comprises a nucleic acid-based molecule. The nucleic acid-based molecule may be an aptamer. The nucleic acid-based molecule may target the CD33 / CD34 antigen, as described in Zaimy, MA et al., Cancer Gene Ther., 2016, 23 , 315-320; or PSMA tumor antigens (e.g., A9, A10, and A9L), as described in Lupold, SE et al., Cancer Res., 2002, 62 , 4029-4033; Dassie, JP et al., Nat. Biotech., 2009, 27 , 839-849; Rockey, WM et al., Nucleic Acid Ther., 2011, 21 , 299-314; or any other tumor antigen known to those skilled in the art, such as Orava, E., Biochem. Biophys. Acta, 2010, 1798 , described in 2190-2200.
[0338] Aptamers are nucleic acid or peptide molecules that are assumed to have a specific sequence-dependent shape and bind to a specific target ligand (based on the lock and key coordination between the aptamer and the ligand). Typically, aptamers can include single-stranded or double-stranded DNA molecules (ssDNA or dsDNA) or single-stranded RNA molecules (ssRNA). Peptide aptamers consist of short variable peptide domains connected to a protein framework at both ends. Aptamers can be used to bind both nucleic acid and non-nucleic acid targets.
[0339] Suitable aptamers can be selected from a pool of random sequences from which specific aptamers that bind to a selected antigen with high affinity can be identified. Methods for generating and selecting aptamers with desired specificity are well known to those skilled in the art and include the SELEX (Systematic Evolution of Ligands by Exponential Enrichment) process. Briefly, large oligonucleotide libraries are generated, allowing large numbers of functional nucleic acids to be isolated by an iterative process of in vitro selection and subsequent amplification by polymerase chain reaction. Preferred methods for generating aptamers include those disclosed in WO2004 / 042083.
[0340] In an alternative embodiment, T comprises a peptide or a modified peptide. The peptide or modified peptide may include an RGD sequence motif (e.g., Mousavizadeh, A., Colloids Surfaces B., 2017,158 , 507-517) to contain a linear RGD peptide sequence or a cyclized form thereof (as described in Belvisi, L et al., Current Topics in Medicinal Chemistry, 2016, 16 , 314-329). Exemplary embodiments of RGD ligands that the targeting moiety can target and bind to are as follows:

The peptide or modified peptide may also include albumin or a modified form of albumin, wherein the albumin may be coupled to a suitable linker via Cys34 or other suitable residues, as described in Larsen et al., Mol Cell Ther., 2016, 4 , as described in 3.
[0343] In an alternative embodiment, T comprises carbohydrates or modified carbohydrate molecules that can target tumor-associated carbohydrate antigen receptors on target tumors and cells. For example, glycosphingolipids, gangliosides, sialic acid, and mucins can indicate malignant transformation and abnormal glycosylation patterns on cancer cells (as reviewed in Feng, D. et al., ACS Chem. Biol., 2016, 11, 850-863; Hakomori, S., Ann. Rev. Immunol., 1984, 2, 103-126; Dube, DH and Bertozzi, CR, Nat. Rev. Drug Disc., 2005, 4, 477-488), and targeting ligands based on carbohydrate molecules (e.g., mannose, galactose, or cerebrosidase derivatives) have been designed for them. In a related approach, cell surface receptors on the tissue of interest can also be targeted; recent examples include derivatives of N-acetyl-galactosamine (GalNAc), which have been developed for targeting asialoglycoprotein receptors on hepatocytes, reviewed in D'Souza, A. et al., J. Controlled Rel., 2015, 203, 126-139, and recent examples in Sanhueza, CA et al., JACS, 2017, 139, 3528-3536.

For example, folic acid or its derivatives can be used to target folate receptors α, β or γ (FRα, FRβ and FRγ). In particular, FRα is known to be expressed in multiple endothelial tumor types (e.g., breast, lung and kidney tumors) (for a recent review, see Fernandez, M. et al., 2018, 4, 790-810), and conjugates of folate derivatives and toxins have been previously described (Vlahov, I. and Leamon, CP, Bioconjugate Chemistry, 2012, 23, 1357-1369).
[0347] The linker can be attached to the compound of formula (I) via a C atom, an O atom, a N atom or a S atom.
[0348] The linker can be cleavable, non-cleavable, hydrophilic or hydrophobic. A cleavable linker can be enzyme sensitive and cleavable by an enzyme such as a protease. For example, a cleavable linker can be a valine-citrulline linker or a valine-alanine linker. For example:

[0350] The non-cleavable linker may be insensitive to proteases.
[0351] The inventors have found that the compounds of the invention can be functionalized in various positions with various linkers and spacers to provide coupled molecules. The linkers can contain a self-cleaving group (e.g., p-aminobenzyl ether or amine and / or valine-citrulline unit) designed to release the parent ACSS after a hydrolysis event (e.g., after amide, peptide or carbamate hydrolysis). 2 Inhibitor.

[0360] The compound of formula (I) or the conjugate of formula (II) can be combined in a composition having many different forms, especially depending on the mode in which the composition is to be used. Thus, for example, the composition can be in the form of a powder, tablet, capsule, liquid, ointment, cream, gel, hydrogel, aerosol, spray, colloidal solution, transdermal patch, liposomal suspension or any other suitable form that can be administered to a human or animal in need of treatment. It should be understood that the vehicle of the medicament of the present invention should be well tolerated by the individual to whom it is administered.
[0361] The medicaments comprising the compounds described herein can be used in a variety of ways. Suitable modes of administration include oral, intratumoral, parenteral, topical, inhalation / intranasal, rectal / intravaginal and ocular / aural administration.
[0362] Formulations suitable for the above modes of administration can be formulated for immediate release and / or modified release. Modified release formulations include delayed release, sustained release, pulsed release, controlled release, targeted release, and programmed release.
[0363] The compounds of the present invention can be administered orally. Oral administration may involve swallowing so that the compound enters the gastrointestinal tract, or buccal or sublingual administration may be employed, whereby the compound enters the bloodstream directly from the oral cavity. Formulations suitable for oral administration include solid formulations (e.g., tablets), capsules containing microparticles, liquids or powders, lozenge-shaped tablets (including liquid fillers), chewables, multi- and nanoparticles, gels, solid solutions, liposomes, films, vaginal suppositories, sprays, liquid formulations, and buccal / mucoadhesive patches.
[0364] Liquid formulations include suspensions, solutions, syrups and elixirs. Such formulations can be used as fillers in soft or hard capsules and typically include a carrier (e.g., water, ethanol, polyethylene glycol, propylene glycol, methylcellulose or a suitable oil) and one or more emulsifiers and / or suspending agents. Liquid formulations can also be prepared, for example, by reconstituting a solid in a pouch.
[0365] The compounds of the invention may also be used in fast dissolving, fast disintegrating dosage forms such as those described in Expert Opinion in Therapeutic Patents, 11(6), 981-986, Liang and Chen (2001).
[0366] For tablet dosage forms, depending on the dosage, the drug may account for 1% to 80% by weight of the dosage form, more typically 5% to 60% by weight of the dosage form. In addition to the drug, tablets typically contain a disintegrant. Examples of disintegrants include sodium starch glycolate, sodium carboxymethylcellulose, calcium carboxymethylcellulose, cross-linked sodium carboxymethylcellulose, crospovidone, polyvinyl pyrrolidone, methylcellulose, microcrystalline cellulose, hydroxypropyl cellulose substituted with a low carbon alkyl group, starch, pregelatinized starch, and sodium alginate. Typically, the disintegrant will account for 1% to 25% by weight of the dosage form, preferably 5% to 20% by weight.
[0367] Binders are often used to impart cohesive qualities to tablet formulations. Suitable binders include microcrystalline cellulose, gelatin, sugars, polyethylene glycol, natural and synthetic gums, polyvinyl pyrrolidone, pregelatinized starch, hydroxypropyl cellulose, and hydroxypropyl methylcellulose. Tablets may also contain diluents such as lactose (monohydrate, spray-dried monohydrate, anhydrous, and the like), mannitol, xylitol, dextrose, sucrose, sorbitol, microcrystalline cellulose, starch, and dibasic calcium phosphate dihydrate.
[0368] Tablets may also optionally include surfactants (e.g., sodium lauryl sulfate and polysorbate 80) and glidants (e.g., silicon dioxide and talc). When present, surfactants may comprise 0.2% to 5% by weight of the tablet, and glidants may comprise 0.2% to 1% by weight of the tablet.
[0369] Tablets also typically contain lubricants, such as magnesium stearate, calcium stearate, zinc stearate, sodium stearyl fumarate, and a mixture of magnesium stearate and sodium lauryl sulfate. Lubricants typically account for 0.25% to 10% by weight, preferably 0.5% to 3% by weight of the tablet. Other possible ingredients include antioxidants, colorants, flavoring agents, preservatives, and taste masking agents.
[0370] An exemplary tablet contains up to about 80% by weight of the drug, about 10% to about 90% by weight of the binder, about 0% to about 85% by weight of the diluent, about 2% to about 10% by weight of the disintegrant, and about 0.25% to about 10% by weight of the lubricant. The tablet blend may be formed into a tablet directly or by roller compression. Alternatively, the tablet blend or blend portion may be wet, dry or melt granulated, melt coagulated, or extruded before tableting. The final formulation may include one or more layers and may be coated or uncoated; it may even be encapsulated. Tablet formulations are discussed in "Pharmaceutical Dosage Forms: Tablets", Vol. 1, H. Lieberman and L. Lachman (Marcel Dekker, New York, 1980).
[0371] Suitable modified release formulations for the purposes of the present invention are described in U.S. Pat. No. 6,106,864. Details of other suitable release technologies (e.g., high energy dispersions and osmotic and coated particles) are found in "Pharmaceutical Technology On-line", 25(2), 1-14, Verma et al. (2001). The use of chewing gum to achieve controlled release is described in WO 00 / 35298.
[0372] The compounds of the invention can also be administered directly into the bloodstream, muscle or internal organs. Suitable modes for parenteral administration include intravenous, intraarterial, intraperitoneal, intrathecal, intraventricular, intraurethral, intrasternal, intracranial, intramuscular and subcutaneous administration. Suitable devices for parenteral administration include needle (including microneedle) syringes, needle-free syringes and infusion techniques.
[0373] Parenteral formulations are typically aqueous solutions that may contain excipients (e.g., salts, carbohydrates) and buffers (preferably pH 3 to 9), but for some applications may be more appropriately formulated as sterile non-aqueous solutions or in dry form for use in combination with a suitable vehicle (e.g., sterile, pyrogen-free water).
[0374] The preparation of parenteral formulations under sterile conditions, for example by lyophilization, is readily accomplished using standard pharmaceutical techniques well known to those skilled in the art.
[0375] The solubility of the compound of formula (I) and the conjugate of formula (II) for preparing parenteral solutions can be enhanced by appropriate formulation techniques (e.g., incorporation of solubilizers). The formulations for parenteral administration can be formulated to release directly and / or in a modified manner. The formulations released in a modified manner include delayed release, sustained release, pulsed release, controlled release, targeted release, and programmed release. Therefore, the compounds of the present invention can be formulated into solid, semisolid, or thixotropic liquids for administration in the form of implanted reservoirs, thereby releasing the active compound in a modified manner. Examples of the formulations include drug-coated stents and poly (dl-lactic-co-glycol) acid (PGLA) microspheres.
[0376] The compounds of the invention may also be administered topically to the skin or mucous membranes, i.e., transdermally or transdermally. Typical formulations for this purpose include gels, hydrogels, lotions, solutions, creams, ointments, dusting powders, dressings, foams, films, skin patches, wafers, implants, sponges, fibers, bandages, and microemulsions. Liposomes may also be used. Typical carriers include alcohol, water, mineral oil, liquid petrolatum, white petrolatum, glycerol, polyethylene glycol, and propylene glycol. Penetration enhancers may be included, see, for example, J Pharm Sci, 88(10), 955-958, Finnin and Morgan (October 1999).
[0377] Other local administration methods include electroporation, iontophoresis, phonophoresis, sonication, and microneedle or needle-free (e.g., Powderject TM 、Bioject TM etc.) for delivery by injection.
[0378] The compounds of the invention may also be administered intranasally or by inhalation, typically in the form of a dry powder from a dry powder inhaler (alone, as a mixture (e.g., a dry blend with lactose) or as mixed component particles (e.g., mixed with a phospholipid, such as phosphatidylcholine)) or as an aerosol spray from a pressurized container, pump, injector, nebulizer (preferably one that uses electrohydrodynamics to generate a fine mist) or sprayer (with or without a suitable propellant, such as 1,1,1,2-tetrafluoroethane or 1,1,1,2,3,3,3-heptafluoropropane). For intranasal use, the powder may include a bioadhesive, such as chitosan or cyclodextrin.
[0379] The pressurized container, pump, spray, atomizer or nebulizer contains a solution or suspension of the compound of the invention, which includes, for example, ethanol, aqueous ethanol or a suitable alternative for dispersion, solubilization or prolonged release of the active substance, a propellant as a solvent and optionally a surfactant (for example sorbitan trioleate, oleic acid or oligolactic acid).
[0380] Before use in dry powder or suspension formulations, the drug product is micronized to a size suitable for delivery by inhalation (usually less than 5 microns). This can be achieved by any appropriate comminution method (e.g., spiral jet milling, fluidized bed jet milling, supercritical fluid processing to form nanoparticles, high pressure homogenization or spray drying.
[0381] Capsules (e.g. made from gelatin or hydroxypropylmethylcellulose), blisters and cartridges for use in an inhaler or insufflator may be formulated to contain a powder mix of a compound of the invention, a suitable powder base such as lactose or starch, and a performance modifier such as L-leucine, mannitol or magnesium stearate. Lactose may be anhydrous or in the form of a monohydrate, the latter being preferred. Other suitable excipients include dextran, glucose, maltose, sorbitol, xylitol, fructose, sucrose and trehalose.
[0382] Solution formulations suitable for use in atomizers that use electrohydrodynamics to produce fine mist may contain 1 μg to 20 mg of the compound of the invention per actuation, and the actuation volume may vary from 1 μL to 100 μL. Typical formulations may include a compound of formula (I) or a conjugate of formula (II), propylene glycol, sterile water, ethanol, and sodium chloride. Alternative solvents that can be used to replace propylene glycol include glycerol and polyethylene glycol.
[0383] Suitable flavors (eg, menthol and levomenthol) or sweeteners (eg, saccharin or saccharin sodium) may be added to those formulations of the invention intended for inhaled / intranasal administration.
[0384] In the case of dry powder inhalers and aerosols, the dosage unit is determined by means of a valve that delivers a metered amount. The units of the invention are typically configured to administer a metered dose or "puff" containing 1 μg to 100 mg of a compound of formula (I) or a conjugate of formula (II). The overall dose will typically be in the range of 1 μg to 200 mg, which can be administered in a single dose or more typically as divided doses over a day.
[0385] The compounds of the invention may be administered rectally or vaginally, for example, in the form of a suppository, pessary, microbicide, vaginal ring or enema. Cocoa butter is a traditional suppository base, but a variety of alternatives may be used as desired.
[0386] The compounds of the invention can also be administered directly to the eye or ear, usually in the form of drops of a micronized suspension or solution in isotonic and pH-adjusted sterile saline. Other formulations suitable for administration through the eye and ear include ointments, biodegradable (e.g., absorbable gel sponges, collagen) and non-biodegradable (e.g., silicone) implants, sheets, lenses, and microparticles or vesicular systems (e.g., vesicles or liposomes). Polymers such as cross-linked polyacrylic acid, polyvinyl alcohol, hyaluronic acid, cellulose polymers (e.g., hydroxypropyl methylcellulose, hydroxyethyl cellulose, or methylcellulose) or heteropolysaccharide polymers (e.g., gellan gum) can be incorporated together with preservatives (e.g., benzalkonium chloride). The formulation can also be delivered by iontophoresis.
[0387] The compounds of the invention can also be administered directly to the site of interest by injection of a solution or suspension containing the active drug substance. The site of interest may be a tumor and the compound may be administered by intratumoral injection. Typical injection solutions include propylene glycol, sterile water, ethanol, and sodium chloride. Alternative solvents that can be used to replace propylene glycol include glycerol and polyethylene glycol.
[0388] The compounds of the present invention may be used in combination with soluble macromolecules (such as cyclodextrin and suitable derivatives thereof or polyethylene glycol-containing polymers) to improve their solubility, dissolution rate, taste masking, bioavailability and / or stability when used in any of the above administration routes.
[0389] Drug-cyclodextrin complexes, for example, are generally found to be useful for most dosage forms and routes of administration. Both inclusion and non-inclusion complexes can be used. As an alternative to direct complexing with the drug, the cyclodextrin can be used as an auxiliary additive, that is, as a carrier, diluent or solubilizer. The most commonly used for these purposes are alpha, beta and gamma cyclodextrins, examples of which can be found in International Patent Applications Nos. WO 91 / 11172, WO 94 / 02518 and WO 98 / 55148.
[0390] It should be understood that the required amount of the compound is determined according to its biological activity and bioavailability, which in turn depends on the mode of administration, the physiochemical properties of the compound, and whether it is used as a monotherapy or a combination therapy. The frequency of administration is also affected by the half-life of the compound in the treated individual. The most preferred dosage can be determined by a person skilled in the art and varies with the specific compound used, the concentration of the pharmaceutical composition, the mode of administration, and the progression of the disease. Other factors according to the specific individual being treated may require adjustment of the dosage, including the age, weight, sex, diet, and administration time of the individual.
[0391] Typically, for administration to humans, the total daily dose of the compounds of the invention is typically in the range of 100 μg to 10 g (e.g., 1 mg to 1 g, e.g., 10 mg to 500 mg). For example, oral administration may require a total daily dose of 25 mg to 250 mg. The total daily dose may be administered in a single or divided dose and may be outside the typical range given herein at the discretion of the physician. These doses are based on a general human subject weighing about 60 kg to 70 kg. The physician will be able to easily determine the dose for subjects whose weight exceeds this range (e.g., infants and the elderly).
[0392] The compounds can be administered before, during or after the onset of the disease to be treated.
[0393] Specific formulations and precise treatment regimens (e.g., daily doses and frequency of administration of the compounds) including the compounds of the invention can be formulated using known procedures (e.g., those commonly used in the pharmaceutical industry, such as in vivo experiments, clinical trials, etc.). The inventors believe that they are the first to describe pharmaceutical compositions for treating diseases based on the use of the compounds of the invention.
[0394] Therefore, in an eighth aspect of the present invention, there is provided a pharmaceutical composition comprising a compound according to the first aspect or a pharmaceutically acceptable salt, solvate, tautomeric form or polymorph thereof or a conjugate according to the second aspect and a pharmaceutically acceptable vehicle.

[0396] A "subject" may be a vertebrate, a mammal, or a domestic animal. Thus, the compounds, compositions, and medicaments of the invention may be used to treat any mammal (e.g., livestock (e.g., horses), pets), or may be used in other veterinary applications. However, most preferably, the subject is a human.
[0397] A "therapeutically effective amount" of a compound is an amount that, when administered to a subject, treats the target disease or produces the desired effect (i.e., inhibits ACSS 2 Any amount of drug required for protein).
[0398] For example, the therapeutically effective amount of the compound used may be about 0.01 mg to about 800 mg and preferably about 0.01 mg to about 500 mg. Preferably, the amount of the compound is about 0.1 mg to about 250 mg and most preferably about 0.1 mg to about 20 mg.

Pharmaceutically acceptable solid medium can include one or more substances that can also be used as the following: flavoring agent, lubricant, solubilizer, suspending agent, dye, filler, glidant, compression aid, inert adhesive, sweetener, preservative, dye, coating or tablet disintegrant. The medium can also be an encapsulation material. In powder, the medium is a fine solid mixed with the fine active agent of the present invention (that is, the compound according to the first, second and third aspects). In tablets, the active compound can be mixed with the medium with the desired compression properties in a suitable proportion and compacted into the desired shape and size. Powders and tablets preferably contain up to 99% of the active compound. Suitable solid mediums include (for example) calcium phosphate, magnesium stearate, talc, sugar, lactose, dextrin, starch, gelatin, cellulose, polyvinyl pyrrolidine, low melting point wax and ion exchange resin. In another embodiment, the pharmaceutical medium can be a gel and the composition can be in the form of cream or the like.
[0401] However, the pharmaceutical vehicle can be a liquid, and the pharmaceutical composition is in the form of a solution. Liquid vehicles can be used to prepare solutions, suspensions, emulsions, syrups, elixirs and pressurized compositions. The compounds of the present invention can be dissolved or suspended in a pharmaceutically acceptable liquid vehicle (e.g., water, an organic solvent, a mixture of the two, or a pharmaceutically acceptable oil or fat). The liquid vehicle may contain other suitable pharmaceutical active agents, such as solubilizers, emulsifiers, buffers, preservatives, sweeteners, flavoring agents, suspending agents, thickeners, colorants, viscosity modifiers, stabilizers or osmotic regulators. Suitable examples of liquid vehicles for oral and parenteral administration include water (partially containing the above-mentioned additives, such as cellulose derivatives, preferably sodium carboxymethylcellulose solutions), alcohols (including alcohols and polyols, such as glycols) and their derivatives and oils (e.g., fractionated coconut oil and peanut oil). For parenteral administration, the vehicle may also be an oily ester, such as ethyl oleate and isopropyl myristate. Sterile liquid vehicles can be used for parenteral administration in the form of sterile liquid compositions. The liquid vehicle for pressurized compositions can be halogenated hydrocarbon or other pharmaceutically acceptable propellant.
[0402] Liquid pharmaceutical compositions (which are sterile solutions or suspensions) can be utilized by, for example, intramuscular, intrathecal, epidural, intraperitoneal, intravenous, and especially subcutaneous injection. The compound can be prepared as a sterile solid composition that can be dissolved or suspended using sterile water, saline or other suitable sterile injectable media when administered.
[0403] The compounds and compositions of the present invention can be administered in the form of sterile solutions or suspensions containing other solutes or suspending agents (e.g., sufficient saline or glucose to make the solution isotonic), bile salts, gum arabic, gelatin, sorbitan monooleate, polysorbate 80 (oleate of sorbitol and its anhydride copolymerized with ethylene oxide), and the like. The compounds used in the present invention can also be orally administered in the form of liquid or solid compositions. Compositions suitable for oral administration include solid forms (e.g., pills, capsules, granules, tablets, and powders) and liquid forms (e.g., solutions, syrups, elixirs, and suspensions). Forms useful for parenteral administration include sterile solutions, emulsions, and suspensions.
[0404] It is known to those skilled in the art that active drug ingredients can be converted into prodrugs, which are metabolically unstable derivatives that are converted into active drug substances in the body. Also included within the scope of the present invention are prodrugs, which are compounds of formula (I) containing metabolically or hydrolytically unstable moieties that are converted into active drugs of formula (I) in vivo. Processes for converting prodrugs into active drug substances include, but are not limited to, ester or carbonate or carbamate hydrolysis, phosphate hydrolysis, S-oxidation, N-oxidation, dealkylation, and metabolic oxidation, as described in Beaumont et al., Curr. Drug Metab., 2003, 4, 461-485 and Huttenen et al., Pharmacological Reviews, 2011, 63, 750-771. Such prodrug derivatives may provide improved solubility, stability, or permeability compared to the parent drug substance, or may more preferably allow administration of the drug substance by alternative routes of administration, such as in the form of an intravenous solution.
[0405] Also included within the scope of the present invention are soft drugs or antedrugs, which are compounds of formula (I) containing metabolically or hydrolytically labile moieties which are converted in vivo into inert derivatives. Processes for converting active drug substances into inert derivatives include, but are not limited to, ester hydrolysis, S-oxidation, N-oxidation, dealkylation, and metabolic oxidation, as described, for example, in Pearce et al., Drug Metab. Dispos., 2006, 34, 1035-1040 and B. Testa, Prodrug and Soft Drug Design, Comprehensive Medicinal Chemistry II, Vol. 5, Elsevier, Oxford, 2007, pp. 1009-1041 and Bodor, N., Chem. Tech., 1984, 14, 28-38.
[0406] Included within the scope of the present invention are all pharmaceutically acceptable isotopically-labeled compounds of the present invention wherein one or more atoms are replaced by an atom having the same atomic number but an atomic mass or mass number different from the atomic mass or mass number predominant in nature.
[0407] Examples of suitable isotopes for incorporation into the compounds of the invention include isotopes of hydrogen (e.g. 2 H and 3 H), carbon (e.g. 11 C. 13 C and 14 C), chlorine (e.g. 36Cl), fluorine (e.g. 18 F), iodine (e.g. 123 I and 125 I), nitrogen (e.g. 13 N and 15 N), oxygen (e.g. 15 O. 17 O and 18 O), phosphorus (e.g. 32 P) and sulfur (e.g. 35 S).
[0408] Certain isotopically-labeled compounds of the invention (e.g., those incorporating a radioactive isotope) are useful in drug and / or substrate tissue distribution studies. 3 H) and carbon-14 (i.e. 14 C) are particularly useful for this purpose because they are easy to incorporate and can be easily detected. The use of isotopes (e.g., deuterium, 2 H) substitution may offer certain therapeutic advantages due to greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements, and thus may be preferred in some circumstances.
