Abstract
Description
Technical Field
[0001] The present invention relates to a novel pyrido[4,3-d]pyrimidine compound as a Kirsten rat sarcoma viral homolog (KRAS) inhibitor, the present invention also relates to the preparation of the compound and the intermediate used in the preparation, a composition containing the compound, and the use of the compound for treating KRAS-related diseases, such as cancer. Background Art
[0002] KRAS, HRAS (Harvey rat sarcoma virus) and NRAS (neuroblastoma RAS viral gene homolog; Neuroblastoma RAS Viral Oncogene Homolog) belong to a group of GTPases that are essential for cell survival and proliferation through complex signaling cascades. Mutated RAS genes are found in approximately 30% of all cancers (Hyun et al., 2021, Int. J. Mol. Sci. 22 (22), 12142). KRAS is the most commonly mutated RAS isoform in cancer cells (up to 85%), which causes the development of cancers including non-small cell lung cancer (NSCLC), colorectal cancer and pancreatic cancer, which has significant unmet medical needs both overall and individually for affected patients. KRAS mutations are widely seen in pancreatic ductal carcinoma (PDAC). Mutations in KRAS have been observed in 30% of NSCLC cases, which is the main (80%) form of lung cancer. KRAS mutations seen in NSCLC include G12C in 39%, G12V in 18-21%, and G12D in 17-18%. KRAS mutations occur in 35-45% of colon cancers and lead to drug resistance.
[0003] Inhibitors of KRAS have been sought for decades, with recent progress in the approval of Sotolasib and subsequent KRASG12C-targeted compounds in trials (Palmer et al. 2021, NPJ Precision Oncology, 5, 98). Sotolasib specifically targets mutations in KRAS via covalent modification of mutant cysteine at position 12. For this reason, when considering other major KRAS mutations, such as G12V and G12D, Sotolasib and other currently known KRAS inhibitors that rely on the same mechanism of action may have a narrow therapeutic range and limited use.
[0004] Therefore, there remains a need for new KRAS inhibitors that can be used to treat a wider range of cancers. Summary of the invention
[0005] The present invention provides, in part, compounds of formula (I) to formula (VII), and pharmaceutically acceptable salts thereof. The compounds of the present invention can inhibit the activity of all KRAS G12C, KRAS G12D, and KRAS G12V receptors, and can be used to treat, prevent, inhibit, and improve diseases mediated by any of KRAS G12C, KRAS G12D, and KRAS G12V receptors or combinations thereof, such as cancer, disorders, and conditions.

[0199] As used herein, when used to modify a numerically defined parameter (e.g., a dosage of 5 mg), the term "about" means that the variation of the parameter can be as much as 10% lower or higher than the specified value of the parameter. For example, a dosage of about 5 mg means 5% ± 10%, i.e., it can vary between 4.5 mg and 5.5 mg.
[0200] If substituents are described as being "independently selected" from a group, each substituent is selected independently of the others. Thus, each substituent may be the same as or different from the other substituent(s).

[0224] Salts encompassed within the term "pharmaceutically acceptable salts" refer to compounds of the invention which are generally prepared by reacting the free base or free acid with a suitable organic or inorganic acid or base, respectively, to provide salts of the compounds of the invention suitable for administration to a subject or patient.
[0225] In addition, compounds of formula (I) may also include other salts of such compounds, which are not necessarily pharmaceutically acceptable salts, which can be used as intermediates for one or more of the following: 1) preparing compounds of formula (I); 2) purifying compounds of formula (I); 3) separating enantiomers of compounds of formula (I); or 4) separating diastereomers of compounds of formula (I).
[0226] Suitable acid addition salts are formed from acids which form non-toxic salts. Examples include, but are not limited to, acetate, adipate, aspartate, benzoate, benzenesulfonate, bicarbonate / carbonate, bisulfate / sulfate, borate, camphorsulfonate, citrate, cyclaminate, edisylate, ethanesulfonate, formate, fumarate, gluconate, glucuronate, hexafluorophosphate, hydroxybenzylbenzoate, hydrochloride / chloride, hydrobromide / bromide, hydroiodide / iodide, isethionate, lactate, malate, maleate, malonate, methanesulfonate, methylsulfate, naphthalene dicarboxylate, 2-naphthalenesulfonate, nicotinate, nitrate, orotate, oxalate, palmitate, pamoate, phosphate / hydrogenphosphate / dihydrogenphosphate, pyroglutamate, glucarate, stearate, succinate, tannate, tartrate, toluenesulfonate, trifluoroacetate, 1,5-naphthalene disulfonic acid, and xinafoate.

[0229] For a review of suitable salts, see Paulekun, GS et al., Trends in Active Pharmaceutical Ingredient Salt Selection Based on Analysis of the Orange Book Database, J. Med. Chem. 2007; 50(26), 6665-6672.
[0230] The pharmaceutically acceptable salts of the compounds of the present invention can be prepared by methods well known to those skilled in the art, including, but not limited to, the following steps:
[0231] (i) reacting a compound of the present invention with a desired acid or base;
[0232] (ii) by removing an acid-labile or base-labile protecting group from a suitable precursor of the compound of the invention, or by ring-opening a suitable cyclic precursor, such as a lactone or lactam, using the desired acid or base; or
[0233] (iii) by converting one salt of a compound of the invention into another salt. This can be achieved by reaction with an appropriate acid or base or by means of a suitable ion exchange procedure.
[0234] These procedures are typically carried out in solution. The resulting salt may precipitate out and be collected by filtration or may be recovered by evaporation of the solvent.
[0235] Solvate
[0236] The compounds of the present invention or their pharmaceutically acceptable salts may exist in unsolvated and solvated forms. The term "solvate" is used herein to describe a molecular complex comprising a compound of the present invention or its pharmaceutically acceptable salt, and one or more pharmaceutically acceptable solvent molecules, such as ethanol. When the solvent is water, the term "hydrate" is used.
[0237] In addition, the compounds of formula (I) may also include other solvates of such compounds that are not necessarily pharmaceutically acceptable solvates, which can be used as intermediates for one or more of the following: 1) preparing the compounds of formula (I); 2) purifying the compounds of formula (I); 3) separating the enantiomers of the compounds of formula (I); or 4) separating the diastereomers of the compounds of formula (I).
[0238] The currently accepted classification system for organic hydrates is a system that defines isolated site hydrates, channel hydrates or metal ion coordinated hydrates - see KR Morris's Polymorphism in Pharmaceuti calSolids (HG Brittain, ed., Marcel Dekker, 1995). Isolated site hydrates are hydrates 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 in the lattice channels in close proximity to other water molecules. In metal-ion coordinated hydrates, the water molecules are bound to the metal ions.
[0239] When the solvent or water is tightly bound, the complex can have a well-defined stoichiometry that is independent of humidity. However, when the solvent or water is weakly bound (as in channel solvates and hygroscopic compounds), the water / solvent content can depend on humidity and drying conditions. In such cases, non-stoichiometry will become the norm.
[0240] Compound
[0241] Also included within the scope of the present invention are multi-component complexes (except salts and solvates) in which the drug and at least one other component are present in stoichiometric or non-stoichiometric amounts. Complexes of this type include inclusion compounds (drug-host inclusion complexes) and co-crystals. The latter are typically defined as crystalline complexes of neutral molecular components bound together via non-covalent interactions, such as complexes (co-crystals) that can form hydrogen bonds with neutral molecules or with salts. Co-crystals can be prepared by melt crystallization, by recrystallization from a solvent, or by physically grinding the components together - see O. Almarsson and MJ Zaworotko, Chem Commun, 17, 1889-1896 (2004). For a general review of multi-component complexes, see Haleblian, J Pharm Sci, 64 (8), 1269-1288 (August 1975).
[0242] Solid form
[0243] The compounds of the present invention can exist in a continuous solid state form ranging from completely amorphous to completely crystalline. The term "amorphous" refers to a state in which a material lacks long-range order at the molecular level and can exhibit the physical properties of a solid or liquid depending on the temperature. Typically, such a material does not produce a unique X-ray diffraction pattern, and while exhibiting the properties of a solid, is more formally described as a liquid. Upon heating, a change in the properties of a solid to the properties of a liquid occurs, characterized by a change in state, typically secondary ("glass transition"). The term "crystalline" refers to a solid phase in which a material has a regularly ordered internal structure at the molecular level and produces a unique X-ray diffraction pattern with a specified peak. Such a material will exhibit the properties of a liquid when fully heated, but the solid becomes a liquid characterized by a phase transition, typically primary ("melting point").
[0244] The compounds of the present invention may also exist in a mesomorphic state (intermediate phase or liquid crystal) when subjected to appropriate conditions. The mesomorphic state is an intermediate state between a true crystalline state and a true liquid state (melt or solution) and consists of two-dimensional order at the molecular level. Mesomorphisms that occur due to temperature changes are described as "thermotropic", and mesomorphisms that occur due to the addition of a second component such as water or another solvent are described as "lyotropic". Compounds that have the potential to form lyotropic mesophases are described as "amphiphilic" and are composed of molecules with ionic polar head groups (such as -COO - Na + 、-COO - K + or -SO 3 - Na + ) or nonionic polar head groups (such as -N - N + (CH3 ) 3 ) molecular composition.

[0245] Stereoisomers
[0246] The compounds of the present invention may exist in the form of two or more stereoisomers. The stereoisomers of the compounds may include cis and trans isomers (geometric isomers), optical isomers such as R and S enantiomers, diastereomers, rotational isomers, atropisomers and conformational isomers. For example, compounds of the present invention containing one or more asymmetric carbon atoms may exist in the form of two or more stereoisomers.
[0247] The pharmaceutically acceptable salts of the compounds of the present invention may also contain an optically active counter ion (eg, d-lactate or L-lysine) or a racemic counter ion (eg, dl-tartrate or dl-arginine).
[0248] Cis / trans isomers may be separated by conventional techniques well known to those skilled in the art, for example chromatography and fractional crystallization.
[0249] Conventional techniques for preparing / isolating single enantiomers include chiral synthesis from suitable optically pure precursors, or separation of racemates (or racemates of salts or derivatives) using, for example, chiral high pressure liquid chromatography (HPLC). Alternatively, the racemate (or racemic precursor) can be reacted with a suitable optically active compound (e.g., alcohol, or a base or acid, such as 1-phenylethylamine or tartaric acid, in the case where the compounds of the present invention contain an acidic or basic moiety). The resulting diastereomeric mixture can be separated by chromatography, fractional crystallization, or by using both of the techniques, and one or both of the diastereomers can be converted into the corresponding pure enantiomers in a manner well known to the technician. The chiral compounds of the present invention (and their chiral precursors) can be obtained in an enantiomerically enriched form using chromatography (usually HPLC). Concentrating the eluent provides an enriched mixture. Chiral chromatography using subcritical and supercritical fluids can be used. Methods for chiral chromatography suitable for use in some embodiments of the present invention are known in the art (see, e.g., Smith, Roger M., Loughborough University, Loughborough, UK; Chromatographic Science Series (1998), 75 (Supercritical Fluid Chromatography with Packed Columns), pp. 223-249 and references cited therein).
[0250] When any racemate is crystallized, there may be two different types of crystals. The first type is the racemic compound (real racemate) mentioned above, which wherein produces a crystal of a homogeneous form containing two enantiomers of equimolar amount. The second type is a racemic mixture or an agglomerate, which wherein produces two crystalline forms each comprising a single enantiomer in equimolar amount. Although the two crystalline forms present in the racemic mixture can have the same physical properties, it can be different from the real racemate in physical properties. The racemic mixture can be separated by conventional techniques known to those skilled in the art-see, for example, ELEiel and SH Wilen's Stereochemistry of Organic Compounds (Wiley, 1994).
[0251] Tautomerism
[0252] When structural isomers can be interconverted via a low energy barrier, tautomeric isomerism ("tautomerism") can occur. This can occur as proton tautomerism in compounds of the invention containing, for example, imino / amino, keto / enol or oxime / nitroso, lactam / lactim groups, or as so-called valence tautomerism in compounds containing aromatic moieties. It can be seen that a single compound can exhibit more than one type of isomerism.
[0253] It must be emphasized that, although the compounds of the present invention have been drawn herein in a single tautomeric form for the sake of brevity, all possible tautomeric forms are encompassed within the scope of the present invention.

[0258] Deuterium (i.e. 2 H) Substitution may provide certain therapeutic advantages resulting from greater metabolic stability.
[0259] Using positron emitting isotopes (such as11 C. 18 F. 15 O and 13 Substitution of N) can be useful in positron emission tomography (PET) studies to examine substrate receptor occupancy.
[0260] In some embodiments, the present invention provides deuterium-labeled (or deuterated) compounds and salts, wherein the chemical formulas and variables of such compounds and salts are each and independently described herein. "Deuterated" means that at least one of the atoms in the compound is deuterium, and its abundance is greater than the natural abundance of deuterium (usually about 0.015%). The skilled person recognizes that in a compound with a hydrogen atom, the hydrogen atom actually represents a mixture of H and D, of which about 0.015% is D. The concentration of deuterium introduced into the deuterium-labeled compounds and salts of the present invention can be defined by the deuterium enrichment factor. It should be understood that one or more deuteriums can be exchanged with hydrogen under physiological conditions.
[0261] In some embodiments, the deuterium compound is selected from any one of the compounds set forth in Table 2 shown in the Examples section.
[0262] In some embodiments, one or more hydrogen atoms at certain metabolic sites on the compounds of the invention are deuterated.

[0264] Pharmaceutically acceptable solvates according to the present invention include those in which the solvent of crystallization may be isotopically substituted, for example D 2 O、d 6 -acetone, d 6 -DMSO.
[0265] Prodrug
[0266] The compounds of the present invention can be administered in the form of prodrugs. Therefore, some derivatives of the compounds of the present invention that may have little or no pharmacological activity in themselves can be converted into compounds of the present invention having the desired activity, for example, by hydrolytic cleavage, especially by hydrolytic cleavage promoted by esterases or peptidases, when applied to the body or body. Such derivatives are referred to as "prodrugs". Other information about the use of prodrugs can be found in "The Expanding Role of Prodrugs in Contemporary Drug Design and Development, Nature Reviews Drug Discovery, 17, 559-587 (2018) (J. Rautio et al.)".
[0267] Prodrugs according to the invention can be produced, for example, by replacing appropriate functional groups present in the compounds of the invention with certain moieties known to those skilled in the art as "pro-moieties" as described, for example, in "Design of Prodrugs" by H.

[0280] Certain compounds of the present invention themselves can serve as prodrugs of other compounds of the present invention. Two compounds of the present invention may also be joined together in prodrug form. In some cases, a prodrug of a compound of the present invention can be produced by internally connecting two functional groups in a compound of the present invention, for example by forming a lactone.

Other functional groups such as NH groups may also undergo conjugation.
[0290] Pharmaceutical composition
[0291] In another embodiment, the present invention includes pharmaceutical compositions. For the purpose of pharmaceutical compositions, the compound itself or a pharmaceutically acceptable salt thereof will be referred to simply as a compound of the present invention.
[0292] "Pharmaceutical composition" refers to a mixture of one or more compounds of the present invention, or pharmaceutically acceptable salts, solvates, hydrates or prodrugs thereof as active ingredients and at least one pharmaceutically acceptable excipient.
[0293] The term "excipient" is used herein to describe any ingredient other than a compound of the invention. The choice of excipient will to a large extent depend on factors such as the mode of administration, the effect of the excipient on solubility and stability, and the nature of the dosage form.
[0294] As used herein, "excipient" includes any and all solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic agents and absorption delaying agents, carriers, diluents, etc. that are compatible physiologically. Examples of excipients include one or more of water, saline, phosphate buffered saline, dextrose, glycerol, ethanol, etc. and combinations thereof, and may include isotonic agents in the composition, such as sugar, sodium chloride or polyols, such as mannitol or sorbitol. Examples of excipients also include various organic solvents (such as hydrates and solvates). If necessary, the pharmaceutical composition may contain additional excipients, such as flavorings, binders / binding agents, lubricants, disintegrants, sweeteners or flavorings, colorants or dyes, etc. For example, for oral administration, tablets containing various excipients (such as citric acid) can be used together with various disintegrants (such as starch, alginic acid and some composite silicates) and binders (such as sucrose, gelatin and gum arabic). Examples of excipients include, but are not limited to, calcium carbonate, calcium phosphate, various sugars and various types of starch, cellulose derivatives, gelatin, vegetable oils and polyethylene glycol. In addition, lubricants (such as magnesium stearate, sodium lauryl sulfate and talc) are generally suitable for tableting purposes. Similar types of solid compositions can also be used in soft and hard filled gelatin capsules. Therefore, non-limiting examples of excipients also include lactose or milk sugar and high molecular weight polyethylene glycol. When it is necessary to orally administer an aqueous suspension or elixir, the active compound therein can be combined with various sweeteners or flavorings, coloring agents or dyes and emulsifiers or suspending agents when necessary, and with other excipients (such as water, ethanol, propylene glycol, glycerol or a combination thereof).
[0295] Examples of excipients also include pharmaceutically acceptable substances such as wetting agents or minor amounts of auxiliary substances such as wetting or emulsifying agents, preservatives or buffers, which enhance the shelf life or effectiveness of the compound.
[0296] The compositions of the present invention can be in various forms. These forms include, for example, liquid, semisolid and solid dosage forms, such as liquid solutions (e.g., injectable and infusible solutions), dispersions or suspensions, tablets, capsules, pills, powders, liposomes and suppositories. The form depends on the intended mode of administration and therapeutic application.
[0297] Typical compositions are in the form of injectable or infusible solutions, such as compositions similar to those commonly used to passively immunize humans with antibodies. One mode of administration is parenteral (e.g., intravenous, subcutaneous, intraperitoneal, intramuscular). In another embodiment, the compound is administered by intravenous infusion or injection. In yet another embodiment, the compound is administered by intramuscular or subcutaneous injection.
[0298] Oral administration of solid dosage forms can be presented, for example, in the form of discrete units, such as hard or soft capsules, pills, cachets, lozenges or tablets, each of which contains a predetermined amount of at least one compound of the present invention. In another embodiment, oral administration can be carried out in the form of a powder or granules. In another embodiment, the oral dosage form is sublingual, such as a lozenge. In such solid dosage forms, the compounds of the present invention are generally combined with one or more adjuvants. Such capsules or tablets may contain controlled release formulations. In the case of capsules, tablets and pills, the dosage form may also contain a buffer or may be prepared with an enteric coating.
[0299] In another embodiment, oral administration can be carried out in liquid dosage form. Liquid dosage forms for oral administration include, for example, pharmaceutically acceptable emulsions, solutions, suspensions, syrups, and elixirs containing inert diluents (e.g., water) commonly used in the art. Such compositions may also include adjuvants, such as one or more of wetting agents, emulsifiers, suspending agents, flavoring agents (e.g., sweeteners), and / or aromatics.
[0300] In another embodiment, the present invention includes parenteral dosage forms. "Parenteral administration" includes, for example, subcutaneous injection, intravenous injection, intraperitoneal injection, intramuscular injection, intrasternal injection and infusion. Injectable preparations (i.e., sterile injectable aqueous or oily suspensions) can be prepared according to known techniques using one or more of suitable dispersants, wetting agents and / or suspending agents.
[0301] In another embodiment, the present invention includes topical dosage forms. "Topical application" includes, for example, transdermal and transdermal application (such as via transdermal patch or iontophoresis device), intraocular application, or intranasal or inhalation application. Compositions for topical application also include, for example, topical gels, sprays, ointments and creams. Topical preparations can include compounds that enhance the absorption or penetration of active ingredients through the skin or other affected areas. When the compound of the present invention is applied by a transdermal device, the patch of a reservoir and porous membrane type or a patch of a solid matrix type is used to achieve. Typical preparations for this purpose include gels, hydrogels, lotions, solutions, creams, ointments, powders, dressings, foams, films, skin patches, wafers, implants, sponges, fibers, bandages and microemulsions. Liposomes can also be used. Typical excipients include alcohol, water, mineral oil, liquid paraffin, white paraffin, glycerol, polyethylene glycol and propylene glycol.

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 introduced together with preservatives such as benzalkonium chloride. Such preparations can also be delivered by iontophoresis.
[0303] For intranasal administration, the compounds of the present invention are preferably delivered in the form of a solution or suspension from a pump spray container squeezed or pumped by the patient, or delivered in the form of an aerosol spray presentation from a pressurized container or a nebulizer using a suitable propellant. Preparations suitable for intranasal administration are usually administered in the form of a dry powder from a dry powder inhaler (alone, as a mixture, for example, dry blended with lactose, or as mixed component particles, for example, mixed with phospholipids (such as phosphatidylcholine)), or in the form of an aerosol spray from a pressurized container, a pump, a nebulizer, an atomizer (preferably an atomizer using electrohydrodynamics to generate a fine mist) or a nebulizer 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 contain a bioadhesive, such as chitosan or cyclodextrin.
[0304] In another embodiment, the present invention includes a rectal dosage form. Such a rectal dosage form can be in the form of, for example, a suppository. Cocoa butter is a traditional suppository base, but various substitutes can be used when appropriate.
[0305] Other excipients and modes of administration known in the pharmaceutical field can also be used. The pharmaceutical compositions of the present invention can be prepared by any of the well-known pharmaceutical techniques, such as effective formulation and administration procedures. The above considerations on effective formulation and administration procedures are well known in the art and described in standard textbooks. The formulation of drugs is discussed in, for example, Hoover, John E., Remington's Pharmaceutical Sciences, Mack Publishing Co., Easton, Pennsylvania, 1975; Liberman et al., ed., Pharmaceutical Dosage Forms, Marcel Decker, New York, NY, 1980; and Kibbe et al., ed., Handbook of Pharmaceutical Excipients (3rd edition), American Pharmaceutical Association, Washington, 1999.
[0306] Acceptable excipients are nontoxic to the subject at the dosages and concentrations employed, and may include one or more of the following: 1) buffers, such as phosphate, citrate or other organic acids; 2) salts, such as sodium chloride; 3) antioxidants, such as ascorbic acid or methionine; 4) preservatives, such as octadecyldimethylbenzyl ammonium chloride, hexahydroxyquaternium chloride, benzalkonium chloride, benzethonium chloride, phenol, butyl alcohol or benzyl alcohol; 5) alkyl parabens, such as methyl paraben, propyl paraben, catechol, resorcinol, cyclohexanol, 3-pentanol or m-cresol; 6) low molecular weight (less than about 10 residues) polypeptides; 7) proteins, such as serum albumin, gelatin or immunoglobulin; 8) hydrophilic polymers such as polyvinyl pyrrolidone; 9) amino acids such as glycine, glutamine, asparagine, histidine, arginine or lysine; 10) monosaccharides, disaccharides or other carbohydrates, including glucose, mannose or dextrin; 11) chelating agents such as EDTA; 12) sugars such as sucrose, mannitol, trehalose or sorbitol; 13) salt-forming counterions such as sodium, metal complexes (e.g., Zn-protein complexes), or 14) non-ionic surfactants such as polysorbates (e.g., polysorbate 20 or polysorbate 80), poloxamers or polyethylene glycol (PEG).
[0307] For oral administration, the composition can be provided to the patient in the form of tablets or capsules containing 0.01, 0.05, 0.1, 0.5, 1.0, 2.5, 5.0, 10.0, 15.0, 25.0, 50.0, 75.0, 100, 125, 150, 175, 200, 250, 500 or 1000 mg of active ingredient for symptomatic adjustment of dosage. The medicament generally contains about 0.01 mg to about 500 mg of active ingredient, or in another embodiment, contains about 1 mg to about 100 mg of active ingredient. In the case of intravenous administration, during constant rate infusion, the dosage can be in the range of about 0.01 to about 10 mg / kg / minute.
[0308] Liposomes containing the compounds of the present invention can be prepared by methods known in the art (see, for example, Chang, HI; Yeh, MK; Clinical development of liposome-based drugs: formulation, characterization, and therapeutic efficacy; Int J Nanomedicine 2012; 7; 49-60). Particularly suitable liposomes can be produced by reverse phase evaporation using a lipid composition comprising phosphatidylcholine, cholesterol and PEG-derivatized phosphatidylethanolamine (PEG-PE). Liposomes are extruded through a filter of defined pore size to produce liposomes having a desired diameter.
[0309] The compounds of the invention may also be embedded in microcapsules prepared, for example, by coacervation techniques or by interfacial polymerization, such as hydroxymethylcellulose or gelatin-microcapsules and poly-(methyl methacrylate) microcapsules in colloidal drug delivery systems (e.g., liposomes, albumin microspheres, microemulsions, nanoparticles and nanocapsules) or in macroemulsions, respectively. Such techniques are disclosed in Remington, The Science and Practice of Pharmacy, 20th edition, Mack Publishing (2000).
[0310] Sustained release preparations can be used.Sustained release preparations suitable examples include semipermeable matrixes of solid hydrophobic polymers containing compounds of the present invention, and the matrix is in the form of formed articles, such as films or microcapsules.Examples of sustained release matrixes include polyesters, hydrogels (e.g., poly(2-hydroxyethyl-methacrylate) or poly(vinyl alcohol)), polylactides, copolymers of L-glutamic acid and 7-ethyl-L-glutamate, non-degradable ethylene-vinyl acetate, degradable lactic acid-glycolic acid copolymers (such as copolymers in leuprolide acetate for reservoir suspensions) (injectable microspheres consisting of lactic acid-glycolic acid copolymers and leuprolide acetate), sucrose acetate isobutyrate and poly-D-(-)-3-hydroxybutyric acid.
[0311] Preparations for intravenous administration must be sterile. This is easily achieved, for example, by filtration through a sterile filtration membrane. The compounds of the present invention are typically placed in a container with a sterile access port, such as an intravenous solution bag or vial with a stopper pierceable by a hypodermic injection needle.
[0312] Suitable emulsions can be prepared using commercially available fat emulsions, such as lipid emulsions comprising soybean oil, fat emulsions for intravenous administration (e.g., safflower oil, soybean oil, lecithin and glycerol contained in water), emulsions containing soybean oil and medium-chain triglycerides, and lipid emulsions of cottonseed oil. The active ingredient can be dissolved in a premixed emulsion composition, or alternatively, it can be dissolved in oil (e.g., soybean oil, safflower oil, cottonseed oil, sesame oil, corn oil or almond oil) and in an emulsion formed after mixing with phospholipids (e.g., lecithin, soybean lecithin or soybean lecithin) and water. It should be understood that other ingredients, such as glycerol or glucose, can be added to adjust the emulsion tension. Suitable emulsions will generally contain up to 20% oil, such as between 5% and 20%. Fat emulsions can include fat droplets between 0.1 and 1.0 μm, especially between 0.1 and 0.5 μm and have a pH in the range of 5.5 to 8.0.
[0313] For example, the emulsion composition may be one prepared by mixing the compound of the present invention with a lipid emulsion containing soybean oil or its components (soybean oil, lecithin, glycerin and water).
[0314] Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable aqueous or organic solvents or mixtures thereof, and powders. Liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described above. In some embodiments, the composition is administered by oral or nasal respiratory routes for local or systemic effects. Compositions in preferably sterile pharmaceutically acceptable solvents can be atomized by using gases. Atomized solutions can be directly inhaled from a nebulizer, or a nebulizer can be connected to a mask, curtain or intermittent positive pressure breathing machine. Solutions, suspensions or powder compositions can be preferably administered orally or nasally from a device that delivers the preparation in an appropriate manner.
[0315] Drug intermediate (DPI) is a partially processed material that must undergo other processing steps before it becomes a raw drug. The compound of the present invention can be formulated into a drug intermediate DPI, which contains an active ingredient in a higher free energy form compared to a crystalline form. One reason for using DPI is to improve oral absorption characteristics, which is due to lower solubility, slow dissolution, improved mass transport via the mucus layer adjacent to the epithelial cells, and in some cases, due to limitations caused by biological barriers such as metabolism and transport proteins. Other reasons may include improved solid-state stability and downstream manufacturability. In one embodiment, the drug intermediate contains a compound of the present invention (e.g., amorphous solid dispersion (ASD)) separated and stable in an amorphous form. There are many techniques known in the art for manufacturing ASD, which produces materials suitable for integration into raw drug materials, such as spray-dried dispersions (SDD), melt extrudates (commonly referred to as HME), coprecipitates, amorphous drug nanoparticles and nanoadsorbates. In one embodiment, an amorphous solid dispersion comprises a compound of the present invention and a polymer excipient. Other excipients and the concentrations of the excipient and the compound of the present invention are well known in the art and described in standard textbooks. See, for example, Navnit Shah et al., "Amorphous Solid Dispersions Theory and Practice."

[0346] In another embodiment, such additional anti-cancer therapeutics include compounds that are immuno-oncology agents, including immunomodulatory agents.
[0347] In another embodiment, combinations with pattern recognition receptors (PRRs) are contemplated. PRRs are receptors expressed by cells of the immune system and recognize various molecules associated with pathogens and / or cell damage or death. PRRs participate in both innate and acquired immune responses. PRR agonists can be used to stimulate the immune response of a subject. There are various classes of PRR molecules, including toll-like receptors (TLRs), RIG-I-like receptors (RLRs), nucleotide-binding oligomerization domain (NOD)-like receptors (NLRs), C-type lectin receptors (CLRs), and stimulator of interferon genes (STING) proteins.
[0348] The STING protein acts as both a cyrosolic DNA sensor and an adaptor protein in type 1 interferon signaling. The terms "STING" and "stimulator of interferon genes" refer to any form of the STING protein, as well as variants, isomers, and species homologs that retain at least a portion of the STING activity. Unless otherwise indicated, such as by specific reference to human STING, STING includes all mammalian species of native sequence STING, such as humans, monkeys, and mouse STING is also referred to as TMEM173.
[0349] As used herein, "STING agonist" refers to any molecule that, upon binding to STING, (1) stimulates or activates STING, (2) enhances, increases, promotes, induces or prolongs the activity, function or presence of STING, or (3) enhances, increases, promotes or induces the expression of STING. STING agonists suitable for use in any of the methods, agents and uses of the present invention include, for example, nucleic acid ligands that bind to STING.

[0351] Therapeutic antibodies may have specificity for various different antigens. For example, therapeutic antibodies may be directed to tumor-associated antigens, so that the combination of the antibody and the antigen promotes the death of cells expressing the antigen. In another example, therapeutic antibodies may be directed to antigens on immune cells, so that the combination of the antibody prevents the activity of cells expressing the antigen from being downregulated (and thereby promotes the activity of cells expressing the antigen). In some cases, therapeutic antibodies may work by a variety of different mechanisms (for example, they may simultaneously i) promote cell death of the antigen, and ii) prevent the antigen from causing the activity of immune cells in contact with cells expressing the antigen to be downregulated).
[0352] In another embodiment, such additional anti-cancer therapeutics include antibodies that would be blocking or inhibitory at the target: CTLA-4 (including ipilimumab or tremelimumab), PD-1 or PD-L1 (including atezolizumab, avelumab, cemiplimab, durvalumab, nivolumab, sasanlimab or pembrolizumab), LAG-3, TIM-3 or TIGIT.

[0366] Synthesis method
[0367] The compounds of the present invention can be synthesized by synthetic routes including methods similar to those well known in the chemical arts, particularly according to the descriptions contained herein. Starting materials are generally available from commercial sources or can be prepared using methods well known to those skilled in the art. Many of the compounds used herein are related to or can be derived from compounds in which one or more of scientific interest or commercial needs have emerged. Thus, such compounds can be one or more of the following: 1) commercially available; 2) reported in the literature or 3) prepared by those skilled in the art using materials reported in the literature, based on other generally available substances.
[0368] For the purpose of illustration, the reaction scheme described below provides a potential approach to synthesizing compounds of the present invention and key intermediates. For a more detailed description of individual reaction steps, see the following examples section. Those skilled in the art will appreciate that other synthetic routes can be used to synthesize compounds of the present invention. Although specific starting materials and reagents are discussed below, other starting materials and reagents can be substituted to provide one or more of various derivatives or reaction conditions. In addition, many compounds prepared by the method described below can be modified in addition according to the present invention using conventional chemical methods well known to those skilled in the art.
[0369] The skilled artisan will appreciate that the experimental conditions set forth in the schemes below illustrate suitable conditions for achieving the transformations shown, and may require or need to change the precise conditions for preparing the compounds of the present invention. It will also be appreciated that it may be necessary or necessary to transform in an order different from that described in the schemes, or to modify one or more of the transformations to provide desired compounds of the present invention.
[0370] It should be noted that some preparation methods suitable for preparing the compounds described herein may require protection of distal functional groups (e.g., primary amines, secondary amines, carboxyl groups, etc. in the precursors of the compounds of the present invention). The need for such protection will vary depending on the nature of the distal functional group and the conditions of the preparation method. The need for such protection is easily determined by those skilled in the art. The use of such protection / deprotection methods is also within the technical scope of the art. For a general description of protecting groups and their uses, see March's Advanced Organic Chemistry: Reactions, Mechanisms, and Structure 8th edition.
[0371] For example, if the compound contains an amine or carboxylic acid functional group, such functional group may interfere with the reaction at other sites of the molecule if it is not protected. Therefore, such functional groups can be protected by an appropriate protecting group (PG), which can be removed in subsequent steps. Suitable protecting groups for protecting amines and carboxylic acids include those commonly used in peptide synthesis (such as N-tert-butyloxycarbonyl (Boc), benzyloxycarbonyl (Cbz) and 9-fluorenylmethyleneoxycarbonyl (Fmoc) for amines and lower alkyl groups, or benzyl esters for carboxylic acids), which are generally not chemically reactive under the described reaction conditions and can generally be removed without chemically changing other functional groups in the compounds of the present invention.

Some of the compounds of the present invention contain a single chiral center. In the following schemes, the general method for preparing the compounds is to show in racemic or enantiomerically enriched form. It will be apparent to those skilled in the art that all synthetic transformations can be carried out in a very similar manner, whether the material is enantiomerically enriched or racemic. In addition, the desired optically active material can be split at any desired point in the sequence using well-known methods as described herein and in the chemical literature.
[0447] General method:
[0448] Unless otherwise indicated, the variables in Schemes I to III have the same meanings as defined herein.
[0449] Scheme I: General Method A
[0450]
[0451] As exemplified in Scheme I, 4,7-dichloro-8-fluoro-2-(methylthio)pyrido[4,3-d]pyrimidine (CAS No. 2454396-80-4) can be treated with an amine in the presence of an effective base such as DIPEA in a suitable solvent such as DCM to provide an adduct at the 4-chloro position via a SnAr reaction. The adduct is prepared using a palladium catalyst such as CataCXiumA Pd G3 and a base such as K in a suitable solvent such as dioxane / water. 2 CO 3 or K 3 PO 4), Suzuki reaction is carried out at 7-chloro position to produce naphthol group. 2-thiomethyl can be oxidized to sulfone using an oxidant (such as mCPBA) in a solvent (such as DCM). Sulfone group obtained by replacement of a suitable base (such as LHMDS) in a suitable solvent (such as DCM) can be obtained by alcohol nucleophile (such as ((2R, 7aS)-2-fluorotetrahydro-1H-pyrrolizine-7a (5H)-yl) methanol, CAS No. 2097518-76-6). In some cases, the penultimate intermediate can contain a protecting group, which can be removed by other steps in the synthesis sequence using conditions known in the art (March's Advanced Organic Chemistry: Reactions, Mechanisms, and Structure 8th Edition or Protecting Groups, 10Georg Thieme Verlag, 1994). Compounds at each step can be purified by standard techniques such as column chromatography, crystallization, reversed-phase HPLC or SFC.
[0452] Scheme II: General Method B
[0453]
[0454] As illustrated in Scheme II, 2,4,7-trichloro-8-fluoropyrido[4,3-d]pyrimidine (CAS No. 2454396-80-4) can be treated with an amine in the presence of an effective base (such as DIPEA) in a suitable solvent (such as DCM) to provide an adduct at the 4-chloro position via a SnAr reaction. A second SnAr reaction at the 2-chloro position in the presence of a base (such as DIPEA) in a suitable solvent (such as 1,4-dioxane) at an elevated temperature (such as 90° C.) produces an alcohol nucleophile (such as ((2R,7aS)-2-fluorotetrahydro-1H-pyrrolizine-7a(5H)-yl)methanol, CAS No. 2097518-76-6). Using a palladium catalyst (such as Pd(OAc) 2 / dppf) and a base (such as NaOH) in a suitable solvent (such as CH 3 CN / water), a Suzuki reaction was carried out at the 7-chloro position to generate a naphthol group.
[0455] Scheme III: General Method C
[0456]
[0457] As exemplified in Scheme III, 4,7-dichloro-8-fluoro-2-(methylthio)pyrido[4,3-d]pyrimidine (CAS No. 2454491-14-4) can be treated with a placeholder amine such as 2-(((tert-butyldimethylsilyl)oxy)methyl)piperidine in the presence of an effective base such as DIPEA in an appropriate solvent such as DCM to provide an adduct at the 4-chloro position via a SnAr reaction. The adduct can be prepared using a palladium catalyst such as CataCXium Pd G3 and a base such as K 3 PO 4 ) in a suitable solvent (such as THF / water), a Suzuki reaction at the 7-chloro position generates a naphthol group. The thiomethyl group can be oxidized to the sulfone using an oxidizing agent (such as buffered potassium persulfate (Oxone)) in a solvent (such as acetone / water). The thiomethyl group is reacted in a suitable solvent (such as CH 3 CN), a second SnAr reaction at the 2-sulfonyl position produces an alcohol nucleophile (such as ((2R,7aS)-2-fluorotetrahydro-1H-pyrrolizin-7a(5H)-yl)methanol) at an elevated temperature (such as 80°C). The occupier amine can be removed using a base (such as NaOH) in the presence of a fluoride source (such as TBAF) at an elevated temperature (such as 60°C). Subsequently, the desired C4 amine is added in the presence of 2-chloro-1-methylpyridinium iodide and an effective base (such as DIPEA) in an appropriate solvent (such as 2-MeTHF) to provide an adduct at the 4-oxy subunit position via a SnAr reaction.
[0458] Scheme IV: General Method D
[0459]
[0460] As exemplified in Scheme IV, 4,5,7-trichloro-8-fluoro-2-(methylthio)pyrido[4,3-d]pyrimidine can be treated with an amino alcohol (cyclic or acyclic) in the presence of an effective base (such as DIPEA) in an appropriate solvent (such as DCM) to provide an adduct at the 4-chloro position via a SnAr reaction. 2 CO 3 or K 3 PO 4 ) in a suitable solvent (such as dioxane / water), a Suzuki reaction at the 7-chloro position produces a naphthol group or a naphthyl group. An oxidizing agent (such as potassium persulfate) can be used in a buffered aqueous solvent (containing NaHCO 3and acetone or methyl ethyl ketone), 2-thiomethyl is oxidized to sulfone. This can be accomplished by using an alcohol nucleophile (e.g., ((2R,7aS)-2-fluorotetrahydro-1H-pyrrolizin-7a(5H)-yl)methanol, CAS No. 2097518-76-6) and a suitable base (e.g., LHMDS or LiOTMS) in a suitable solvent (e.g., CH 3 CN) to replace the obtained sulfone group. In some cases, the penultimate intermediate may contain a protecting group, which can be removed by other steps in the synthesis sequence using conditions known in the art (March's Advanced Organic Chemistry: Reactions, Mechanisms, and Structure 8th edition or Protecting Groups, 10 Georg Thieme Verlag, 1994). Standard techniques such as column chromatography, crystallization, reversed-phase HPLC or SFC purification of the compound at each step can be used.

Chem. 2012, 55 (10), 4605. The retention time of the preparative AS-H column with baseline resolution was: 3.01min for peak 1 and 3.70min for peak 2. The er ratio of peak 1 material was 100 / 0. The peak 1 material (1b, 294g, 1.37mol) from the chiral separation was dissolved in EtOH (3.2L) and Boc 2 O (486 g, 2.23 mol), followed by 10% Pd / C (10 g). At 25 °C in H 2 The reaction was stirred under an atmosphere of (60 psi) for 18 h. Subsequently, fresh Pd / C (5 g) was added and the mixture was stirred under an atmosphere of H 2 (60psi) and continued stirring for 30min. HPLC showed that all benzyl groups had been removed.
