Abstract
Description
MTA-COOPERATIVE PRMT5 INHIBITORFIELD OF THE INVENTION
[0001] The present invention relates to compounds used as MTA-cooperative inhibitors of protein arginine N-methyl transferase 5 (PRMT5) . In particular, the present invention relates to MTA-cooperative PRMT5 inhibitors, including their pharmaceutical compositions comprising the compounds and the methods of use thereof.BACKGROUND
[0002] The protein arginine methyltransferase PRMT5 is crucial for maintaining cellular homeostasis by regulating gene transcription, ribosomal biogenesis, mRNA splicing, protein translation, DNA damage response, and immune functions (Musiani, D. et al., Proteomics profiling of arginine methylation defines PRMT5 substrate specificity. Sci. Signaling 2019, 12 (575) , eaat8388) . PRMT5 is a type II arginine methyltransferase that symmetrically dimethylate histones and non-histone proteins. It catalyzes a methyl group transfer from S-adenosyl-L-methionine (SAM) to an omega-nitrogen of the guanidino function of protein L-arginine residues (omega-monomethylation) and a second methyl group to the other omega-nitrogen, resulting in symmetric dimethylarginine (sDMA) (Gary, J. D., and Clarke, S. Prog. Nucleic Acid Res. Mol. Biol 1998, RNA and protein interactions modulated by protein arginine methylation. 61, 65–131) .
[0003] Due to multiple functions involved with PRMT5, complete inactivation of PRMT5 is lethal in most cell lines. Therefore, PRMT5 is considered as an essential gene for cell viability (McDonald, E.R., et al., Project DRIVE: A Compendium of Cancer Dependencies and Synthetic Lethal Relationships Uncovered by Large-Scale, Deep RNAi Screening. Cell 2017, 170 (3) , 577-592) . PRMT5 is an attractive drug target in the field of oncology. Several potent and selective inhibitors targeting the catalytic pocket of PRMT5 have been developed. However, given the essential role of PRMT5 in normal tissue homeostasis, solely inhibiting PRMT5 may cause the toxicity and lead to a limited therapeutic window.
[0004] Methylthioadenosine (MTA) is an endogenous competitor of SAM and partially inhibits PRMT5 without inhibiting PRMT family members other than PRMT5. Studies have shown that inhibition of PRMT5 by MTA will reduce the methylation activity and sensitize cells to PRMT5 inhibitors. MTA is a substrate of methylthioadenosine phosphorylase (MTAP) and can be converted into 5-methylthioribose 1-phosphate (MTR-1-P) by MTAP. Therefore, MTA will not be accumulated in the wild type cells to reduce PRMT5 activity. On the contrary, cells with homozygous deletion of MTAP will cause MTA to be accumulated in the cells, resulting in decreased PRMT5 activity (Kryukov, G.V. et al., MTAP deletion confers enhanced dependency on the arginine methyltransferase PRMT5 in human cancer cells. Science 2016, 351 (6278) , 1214-1218) . Therefore, MTA-cooperated inhibition of PRMT5 will selectively inhibit PRMT5 activity in cells with homozygous deletion of MTAP.
[0005] Homozygous deletions of MTAP are relatively common in cancers with about 15%incidence rate. Higher incidence rates were noticed in glioblastoma, bladder cancer, non-small cell lung cancer, and pancreatic cancer. This loss is due to its proximity to the P16 / CDKN2A tumor suppressor locus. Homozygous deletions of p16 / CDKN2a commonly involve the co-deletion of adjacent genes, such as MTAP (Mavrakis, K.J. et al., Disordered methionine metabolism in MTAP / CDKN2A-deleted cancers leads to dependence on PRMT5. Science 2016, 351 (6278) , 1208-1213) .
[0006] We realized that MTA-cooperative inhibition of PRMT5 activity in MTAP-deficient cancers will provide therapeutic benefit for a wide range of cancers. Thus, there is a need to develop new MTA-cooperative PRMT5 inhibitors that are capable of inhibiting PRMT5 activity in the MTAP-deficient cells.SUMMARY OF THE INVENTION

[0085] As used herein, the term "enantiomers" refers to a pair of stereoisomers that are non-superimposable mirror images of each other. A 1: 1 mixture of a pair of enantiomers is a racemic mixture. The term "enantiomers" is used where appropriate to refer to racemic mixtures. A "diastereomer" is a stereoisomer having at least two atoms that are asymmetric but are not mirror images of each other. Absolute stereochemistry can be assigned according to the Cahn-Ingold-PrelogR-Ssystem. When a compound is a pure enantiomer, the stereochemistry at each chiral carbon can be designated by R or S. Resolved compounds can be represented as (+) or (-) depending on the direction (dextral or levorotary) which they rotate plane polarized light at the wavelength of the sodium D line. Certain compounds described herein contain one or more asymmetric centers or axes and may thus give rise to enantiomers, diastereomers, and other stereoisomeric forms that may be defined, in terms of absolute stereochemistry, as (R) -or (S) -. The present invention is meant to include all such possible isomers, including racemic mixtures, optically pure forms and intermediate mixtures. Optically active (R) -and (S) -isomers may be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. If the compound contains a double bond, the substituent may be in the E or Z configuration. If the compound contains a disubstituted cycloalkyl, the cycloalkyl substituent may have a cis-or trans-configuration.
[0086] As used herein, "prodrugs" are intended to include any covalently bonded carriers that release the active parent drug according to formula (I) through in vivo physiological action, such as hydrolysis, metabolism and the like, when such prodrug is administered to a subject. The suitability and techniques involved in making and using prodrugs are well known by a person of ordinary skill in the art. Prodrugs of the compounds of formula (I) (parent compounds) can be prepared by modifying functional groups present in the compounds in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent compounds. "Prodrugs" include the compounds of formula (I) wherein a hydroxy, amino, or sulfhydryl group is bonded to any group that, when the prodrugs are administered to a subject, cleaves to form a free hydroxyl, free amino, or free sulfhydryl group, respectively. Examples of prodrugs include, but are not limited to, derivatives and metabolites of the compounds of formula (I) that include biohydrolyzable moieties such as biohydrolyzable amides, biohydrolyzable esters, biohydrolyzable carbamates, biohydrolyzable carbonates, biohydrolyzable ureides, and biohydrolyzable phosphate analogues. In certain embodiments, prodrugs of the compounds of formula (I) with carboxyl functional groups are the lower alkyl (e.g., C1-C6) esters of the carboxylic acid. The carboxylate esters are conveniently formed by esterifying any of the carboxylic acid moieties present on the molecule.
[0087] The present invention also includes all pharmaceutically acceptable isotopically labeled compounds identical to those of the present invention except that one or more atoms are replaced by atoms with the same atomic number but different atomic masses or mass numbers from those that predominate in nature. Examples of isotopes suitable for inclusion in the compounds of the invention include, but are not limited to, isotopes of hydrogen (e.g., deuterium (D, 2H) , tritium (T, 3H) ) ; isotopes of carbon (e.g., 11C, 13C, and 14C) ; isotopes of chlorine (e.g., 36Cl) ; isotopes of fluorine (e.g., 18F) ; isotopes of iodine (e.g., 123I and 125I) ; isotopes of nitrogen (e.g., 13N and 15N) ; isotopes of oxygen (e.g., 15O, 17O and 18O) ; isotopes of phosphorus (e.g., 32P) ; and isotopes of sulfur (e.g., 35S) . Certain isotopically labeled compounds of the present invention (e.g., those incorporating radioactive isotopes) may be used in drug and / or substrate tissue distribution studies (e.g., assays) . The radioactive isotopes tritium (i.e., 3H) and carbon-14 (i.e., 14C) are particularly useful for this purpose because they are easy to incorporate and detect. Substitution with positron-emitting isotopes such as 11C, 18F, 15O, and 13N can be used to examine substrate receptor occupancy in positron emission tomography (PET) studies. Isotopically labeled compounds of the invention may be prepared by methods analogous to those described in the accompanying Schemes and / or Examples and Preparations by using appropriate isotopically labeled reagents in place of the previously employed non-labeled reagents. Pharmaceutically acceptable solvates of the invention include those in which the crystallization solvent may be isotopically substituted, for example, D2O, acetone-d6 or DMSO-d6.
