[0060] As will be understood by those skilled in the art, for any and all purposes, particularly in providing written description, all scopes disclosed herein also encompass any and all possible sub-ranges and combinations of sub-ranges thereof.Any listed scope can be easily considered as fully describing and enabling the same scope to be decomposed into at least equal half, one-third, one-quarter, one-fifth, one-tenth, etc. As a non-limiting example, each scope discussed herein can be easily decomposed into lower third, middle third, and upper third, etc. As will be understood by those skilled in the art, all languages such as "at most", "at least", "greater than", "less than", etc. include the listed numbers and refer to the scope of the sub-ranges discussed above subsequently. Finally, as will be understood by those skilled in the art, scope includes each individual member.Therefore, for example, a group with 1 to 3 atoms refers to a group with 1, 2 or 3 atoms.Similarly, a group with 1-5 atoms refers to a group with 1, 2, 3, 4 or 5 atoms, etc.
[0061] As understood by one of ordinary skill in the art, "molecular weight" (also known as "relative molar mass") is a dimensionless quantity but is converted to molar mass by multiplying by 1 gram / mole or by 1 Da, e.g., a compound with a weight average molecular weight of 5,000 has a weight average molar mass of 5,000 g / mol and a weight average molar mass of 5,000 Da.
[0062] Pharmaceutically acceptable salts of the compounds described herein are within the scope of the present technology and include acid addition salts or base addition salts that retain the desired pharmacological activity and are not biologically undesirable (e.g., the salts do not have undue toxicity, allergenicity or irritation, and are bioavailable). When the compounds of the present technology have a basic group (such as, for example, an amino group), pharmaceutically acceptable salts can be formed by inorganic acids (such as hydrochloric acid, hydroboric acid, nitric acid, sulfuric acid, and phosphoric acid), organic acids (such as alginic acid, formic acid, acetic acid, benzoic acid, gluconic acid, fumaric acid, oxalic acid, tartaric acid, lactic acid, maleic acid, citric acid, succinic acid, malic acid, methanesulfonic acid, benzenesulfonic acid, naphthalenesulfonic acid, and p-toluenesulfonic acid) or acidic amino acids (such as aspartic acid and glutamic acid). When the compounds of the present technology have an acidic group (such as, for example, a carboxylic acid group), it can react with metals such as alkali metals and alkaline earth metals (e.g., Na + , Li + , K + , Ca 2+ Mg 2+ 、Zn 2+), ammonia or organic amines (e.g., dicyclohexylamine, trimethylamine, triethylamine, pyridine, picoline, ethanolamine, diethanolamine, triethanolamine) or basic amino acids (e.g., arginine, lysine and ornithine) to form salts. Such salts can be prepared in situ during the isolation and purification of the compound, or by reacting the purified compound in free base or free acid form with a suitable acid or base, respectively, and isolating the salt thus formed.
[0063] Those skilled in the art will understand that the compounds of the present technology can exhibit tautomerism, conformational isomerism, geometric isomerism and / or stereoisomerism. Since the chemical formula drawings in the specification and claims can only represent one possible tautomerism, conformational isomerism, stereochemical or geometric isomeric form, it should be understood that the present technology covers any tautomerism, conformational isomerism, stereochemical and / or geometric isomeric form of the compound having one or more of the utilities described herein, as well as mixtures of these various forms.
[0064] "Tautomers" refer to isomeric forms of compounds that are in equilibrium with each other. The presence and concentration of isomeric forms will depend on the environment in which the compound exists and may differ depending on, for example, whether the compound is solid or in an organic solution or aqueous solution. For example, in aqueous solution, quinolones may exhibit the following isomeric forms (which are also referred to as tautomers of each other):
[0065]
[0066] As another example, guanidine can exhibit the following isomeric forms (also referred to as tautomers of one another) in protic organic solutions:
[0067]
[0068] As representative compounds are limited by structural formulae, it is understood that all formulae of compounds described herein represent all tautomeric forms of the compounds and are within the scope of the present technology.
[0069] Unless a specific stereochemistry is explicitly indicated, stereoisomers (also referred to as optical isomers) of a compound include all chiral, diastereomeric, and racemic forms of the structure. Thus, the compounds used in the present technology include enriched or resolved optical isomers at any or all asymmetric atoms, as apparent from the description. Both racemic and diastereomeric mixtures, as well as individual optical isomers, can be separated or synthesized to be substantially free of their enantiomeric or diastereomeric partners, and these stereoisomers are within the scope of the present technology.
[0070] The compounds of the present technology may exist as solvates (especially hydrates). Hydrates may be formed during the manufacture of the compound or a composition comprising the compound, or hydrates may be formed over time due to the hygroscopic properties of the compound. The compounds of the present technology may also exist as organic solvates (including DMF, ether and alcohol solvates, etc.). The identification and preparation of any particular solvate is within the skill of a person of ordinary skill in synthetic organic chemistry or medicinal chemistry.
[0071] Throughout this disclosure, various publications, patents, and published patent specifications are referenced by identifying citations. Arabic numerals referring to the references are also included in this disclosure, and their complete bibliographic details are provided after the Examples section. The disclosures of these publications, patents, and published patent specifications are hereby incorporated by reference into this disclosure to more fully describe the present technology.
[0072] This technology
[0073] Poly ADP ribose polymerase 1 (PARP1) is a member of a family of proteins involved in numerous cellular processes such as DNA repair, genome stability, and programmed cell death. PARP1 is an ADP-ribosyltransferase that uses NAD+ as a substrate to modify proteins, including itself, through PARylation and detects single-strand DNA breaks, thereby playing an important role in homologous recombination and DNA repair by signaling the enzymatic processes involved in repairing single-strand DNA breaks.
[0074] Several PARP1 inhibitors have been approved for the treatment of breast and ovarian cancers deficient in other DNA repair mechanisms, and additional PARP inhibitors are currently in clinical trials for the treatment of ovarian cancer, pancreatic and biliary malignancies, glioblastoma, lung cancer, and prostate cancer. BRCA1 / 2-deficient cancers are extremely sensitive to PARP1 inhibition, with PARP inhibition being lethal for cells with loss-of-function mutations in BRCA1 and BRCA2. Reduced homologous recombination (HR) capacity through other mechanisms also sensitizes cells to PARP inhibitors. Cells lacking DNA repair defects are typically 1000-fold less susceptible to PARP inhibitors than cells with such defects. PARP inhibitors reduce PARylation and trap PARP1 on DNA, leading to replication fork collapse and cell death.
[0075] However, current PARP1 inhibitors such as talazoparib, olaparib, rucaparib and niraparib do not have good central nervous system (CNS) penetration, and veliparib is ineffective for most tumors. See, for example, Gupta, Shiv K. et al. "PARP inhibitors for sensitization of alkylation chemotherapy inglioblastoma: impact of blood-brain barrier and molecular heterogeneity" Frontiers in oncology 8 (2019): 670; Kizilbash, SH et al. "Restricted delivery of talazoparib across the blood-brain barrier limits the sensitizing effects of PARP inhibition on Temozolomide therapy in glioblastoma" Mol. Cancer Ther, 16 (2017): 2735-2746.
[0076] Therefore, there is a need for PARP inhibitors with improved central nervous system penetration for the treatment of brain cancers such as glioblastoma, neuroblastoma, and medulloblastoma.
[0077] The present technology responds to these needs and provides additional advantages. According to internal proprietary prediction models, it is expected that the compounds of the present technology show desirable blood-brain barrier (BBB) permeability. These proprietary prediction models are further verified by in vitro assays, which have been fully confirmed to predict the BBB permeability of living subjects, and are further verified by in vivo experiments. Therefore, the present technology provides compounds with advantageously improved central nervous system penetration, and compositions and methods particularly suitable for treating central nervous system cancer.

[0099] In addition to those representative dosage forms described above, suitable pharmaceutically acceptable excipients and carriers are generally known to those skilled in the art and are therefore included in the prior art. Such excipients and carriers are described in, for example, "Remingtons Pharmaceutical Sciences" Mack Pub. Co., New Jersey (1991), which is incorporated herein by reference.
[0100] The formulations of the present technology can be designed to be short-acting, fast-releasing, long-acting, and sustained-releasing, as described below. Therefore, the pharmaceutical formulations can also be formulated for controlled or sustained release.
[0101] The compositions of the present invention may also comprise, for example, micelles or liposomes, or some other encapsulation forms, or may be administered in a sustained release form to provide extended storage and / or delivery effects. Thus, pharmaceutical preparations and drugs may be compressed into pills or cylinders and implanted intramuscularly or subcutaneously as reservoir injections or as implants (such as stents). Such implants may be made of known inert materials, such as silicone and biodegradable polymers.
[0102] Specific dosage can be adjusted according to the disease state, age, weight, general health, sex and diet of the subject, dosage interval, administration route, excretion rate and drug combination. Any of the above dosage forms containing an effective amount is completely within the scope of routine experiments, and therefore is completely within the scope of the existing present technology.
[0103] Those skilled in the art can easily determine the effective amount by simply administering the compound of the present technology to the patient in an increasing amount until (for example) the tumor mass of the subject is reduced. The compound of the present technology can be administered to the patient at a dosage level ranging from about 0.1 mg to about 1,000 mg per day. For a normal adult weighing about 70 kg, a dosage ranging from about 0.01 mg to about 100 mg per kg of body weight per day is sufficient. However, the specific dosage used may vary or may be adjusted as appropriate by a person of ordinary skill in the art. For example, the dosage may depend on many factors, including the patient's needs, the severity of tumor-related B-cell malignancies (e.g., non-Hodgkin lymphoma or chronic lymphocytic leukemia), and the pharmacological activity of the compound used. The determination of the optimal dosage for a particular patient is well known to those skilled in the art.
[0104] Various assays and model systems can be readily employed to determine the therapeutic efficacy of treatments according to the present technology. The effectiveness of the compositions (and determination of effective amounts) and methods of the present technology can also be demonstrated by the following: reduction in tumor mass and / or slowing tumor growth and / or affecting the increase in the therapeutic responsiveness of cancer to a second cancer therapy (such as radiotherapy, monoclonal antibodies and / or chemotherapeutic agents).
[0105] For each specified condition described herein, the test subject will exhibit a 10%, 20%, 30%, 50% or greater reduction, up to a 75% to 90% or 95% or greater reduction, in one or more symptoms caused by or associated with the subject's condition, compared to a placebo-treated control subject or other appropriate control subject.
[0106] The compounds of the present technology can also be applied to patients together with other conventional therapeutic agents that can be used to treat tumors or vaccinations. Administration can include oral administration, parenteral administration or nasal administration. In any of these embodiments, administration can include intratumoral injection, subcutaneous injection, intravenous injection, intraperitoneal injection or intramuscular injection. In any of these embodiments, administration can include oral administration. The method of the present technology can also include conventional therapeutic agents and one or more compounds of the present technology in an amount that can potentially or synergistically effectively treat cancer (e.g., breast cancer, ovarian cancer, pancreatic cancer, biliary tract cancer, lung cancer, prostate cancer and / or CNS cancer) sequentially or in combination.
[0107] In one aspect, the compounds of the present technology are administered to a patient in an amount or dosage suitable for therapeutic use. In general, the unit dose comprising the compounds of the present technology will vary according to the patient's considerations. These considerations include, for example, age, regimen, condition, gender, extent of disease, contraindications, concomitant therapy, and the like. Exemplary unit doses based on these considerations can also be adjusted or modified by those skilled in the art. For example, a unit dose for a patient comprising a compound of the present technology can be in the range of 1×10 - 4 g / kg to 1 g / kg, preferably 1×10 -3 The dosage of the compounds of the present technology may also vary between 0.01 mg / kg and 100 mg / kg, or preferably between 0.1 mg / kg and 10 mg / kg.
[0108] The compounds of the present technology can also be modified, for example, by covalently linking an organic moiety or conjugate to improve pharmacokinetic properties, toxicity or bioavailability (e.g., increase in vivo half-life). The conjugate can be a linear or branched hydrophilic polymer group, a fatty acid group or a fatty acid ester group. The polymer group can include a molecular weight that can be adjusted by a person of ordinary skill in the art to improve, for example, pharmacokinetic properties, toxicity or bioavailability. Exemplary conjugates can include polyalkylene glycols (e.g., polyethylene glycol (PEG), polypropylene glycol (PPG)), carbohydrate polymers, amino acid polymers or polyvinyl pyrrolidone and fatty acid or fatty acid ester groups, each of which can independently contain about eight to about seventy carbon atoms. The conjugates used with the compounds of the present technology can also be used as connectors to, for example, any suitable substituent or group, radiolabel (marker or label), halogen, protein, enzyme, polypeptide, other therapeutic agent (e.g., medicine or drug), nucleoside, dye, oligonucleotide, lipid, phospholipid and / or liposome. In one aspect, the conjugate can include polyethyleneamine (PEI), polyglycine, a hybrid of PEI and polyglycine, polyethylene glycol (PEG) or methoxypolyethylene glycol (mPEG). The conjugate can also connect the compound of the present technology to (for example) a label (fluorescent label or luminescent label) or a marker (radionuclide, radioisotope and / or isotope) to form a probe of the present technology. The conjugate used with the compound of the present technology can improve the half-life in vivo in one aspect. Other exemplary conjugates used with the compound of the present technology and their applications and related technologies include those summarized in U.S. Patent No. 5,672,662, which is hereby incorporated by reference herein.
[0109] In another aspect, the present technology provides a method for identifying a target of interest, comprising contacting the target of interest with a detectable or imaging effective amount of a labeled compound of the present technology. A detectable or imaging effective amount is the amount of the labeled compound of the present technology necessary to be detected by the selected detection method. For example, a detectable amount can be an amount of administration sufficient to detect the binding of the labeled compound to the target of interest. Suitable labels are known to those skilled in the art and may include, for example, radioisotopes, radionuclides, isotopes, fluorescent groups, biotin (bound to streptavidin complexes), and chemiluminescent groups. After the labeled compound is bound to the target of interest, the target can be separated, purified, and further characterized (such as by determining the amino acid sequence).
[0110] The terms "association" and / or "binding" may refer to, for example, a chemical or physical interaction between a compound of the present technology and a target of interest. Examples of associations or interactions include covalent bonds, ionic bonds, hydrophilic-hydrophilic interactions, hydrophobic-hydrophobic interactions, and complexes. Association may also generally refer to "binding" or "affinity," as each can be used to describe a variety of chemical or physical interactions. Measuring binding or affinity is also routine for those skilled in the art. For example, a compound of the present technology may bind to or interact with a target of interest or a precursor, portion, fragment, and peptide thereof, and / or their deposits.

[0312] program:
[0313] The PARP1 enzyme assay was performed in a 384-well plate in a total volume of 20 μL in assay buffer. For concentration response curves, compounds were serially diluted 3-fold (from 2 mM top concentration to 0.1013 mM) to generate a 10-point curve and 125 nL was transferred to the assay plate using an Echo sonic dispenser, with a final concentration range of 26.6 μM to 1.35 μM in 10 μL of reaction. Five microliters of a 10 nM PARP1 enzyme and 100 nM core histone (2x) mixture were added to the assay plate and pre-incubated for 30 min at room temperature (RT). The reaction was initiated by adding 5 μL of a 10 μM β-NAD plus 0.02 mg / mL activated DNA (2X) mixture. The reaction was incubated for 60 min at RT. The final concentrations of PARP1 enzyme and substrate were 5 nM and 5 μM, respectively. Positive control (high signal) wells and negative control (low signal) wells were replaced with 125 nL DMSO instead of compound. After incubation, the reaction was terminated by adding 10 μL of 10 μM 3ABA PARP1 inhibitor, incubated for 5 min at RT, and placed in a -80 °C freezer for shipment to the Valo Health site in Branford, CT, where mass spectrometry will be used to directly measure nicotinamide (NAM) levels.

[0362] MDCK-MDR1 Permeability Assay Results for Exemplary Compounds of the Present Technology
[0363] The bidirectional assay (which contains a Mandin Darby canine kidney (MDCK) cell line transfected with the human MDR1 gene (P-glycoprotein; P-gp), which is designed to overexpress the MDR1 efflux transporter, a major efflux transporter at the blood-brain barrier (BBB)) uses an established method to measure the rate of flux of a compound across a polarized cell monolayer. As is well known in the art, data generated from the MDCK-MDR1 permeability assay can be used to predict the in vivo absorption of a drug. The bidirectional MDCK-MDR1 permeability assay can identify and quantify the level of active efflux. Compounds that pass through the cell monolayer in both the apical to basolateral direction (A→B) and the basolateral to apical direction (B→A) are screened, providing a ratio of B→A / A→B (efflux ratio; "ER"). Unlike the Caco-2 assay, the MDCK-MDR1 assay is not subject to potential efflux interference from breast cancer resistance protein (BCRP). When a compound has an ER greater than 2, it indicates that the compound may undergo active efflux. The data can be further used to predict blood-brain barrier (BBB) permeability via calculations from the log(permeability-surface area product) ("logPS") data, which is well known to predict in vivo log([brain concentration] / [plasma concentration]).
[0364] Table 2 below provides initial bidirectional MDCK-MDR1 permeability results for exemplary compounds of the present technology.
