Technical Field

Background

Proteolys-targeting chimera (PROTAC) is a novel strategy for selective knockdown of target proteins by small molecules (Sakamoto KM et al Proc Natl Acad Sci, 2001,98:8554-9.; sakamoto KM et al Methods enzymol 2005; 399:833-847.). PROTAC targets specific proteins and induces their degradation in cells using the ubiquitin-protease system (Zhou P.et al., mol cell.2000;6 (3): 751-756;Neklesa TK et al., pharmacol Ther.2017;174:138-144; lu M.et al., eur J Med chem.2018; 146:251-259;). The normal physiological function of the ubiquitin protease system is responsible for eliminating denatured, mutated or detrimental proteins in the cells. The normal physiological function of the ubiquitin protease system is responsible for eliminating denatured, mutated or detrimental proteins in the cells. Ubiquitin-proteasome system (UPS), also known as ubiquitin-proteasome pathway (UPP), is a common posttranslational regulatory mechanism responsible for protein degradation under normal and pathological conditions (Ardley h. Et al, esays biochem.2005,41,15-30;Komander D.et al, biochem.2012,81,203-229;Grice GL et al, cell rep.2015,12,545-553;Swatek KN et al, cell res.2016,26, 399-422). Ubiquitin is highly conserved in eukaryotic cells, a modified molecule consisting of 76 amino acids, covalently binds and labels a target substrate by a cascade of enzymatic reactions involving the E1, E2 and E3 enzymes. The modified substrate is then recognized by the 26S proteasome complex for ubiquitination-mediated degradation. So far, two E1 enzymes, called UBA1 and UBA6, respectively, have been found. On the other hand, there are approximately 40E 2 enzymes and more than 600E 3 enzymes that provide functional diversity to control the activity of many downstream protein substrates. However, only a limited number of E3 ubiquitin ligases were successfully hijacked for use by the small molecule PROTAC technology: von Hippel-Lindau tumor suppressor protein (VHL), mouse two-minute 2 homolog (MDM 2), apoptosis inhibitor (cIAP) and cereblon (Philipp o.et al., chem. Biol.2017,12, 2570-2578).

Bifunctional compounds consisting of a target protein binding moiety and an E3 ubiquitin ligase binding moiety have been shown to induce proteasome-mediated degradation of selected proteins. Such drug molecules offer the possibility of time-controlled protein expression and are useful in the treatment of related diseases. In recent years, this newly developed method has been widely used in antitumor studies (Lu J.et al, chem biol.2015;22 (6): 755-763;Ottis P.et al, chem biol.2017;12 (4): 892-898; crews CM et al, J Med chem.2018;61 (2): 403-404; neklesa TK et al, pharmacol Ther.2017, 174:138-144K; cermakova et al, molecular, 2018.23 (8); an S. Et al, EBiomedicine,2018.; lebraud H et al, essars biochem.2017;61 (5): 517-527.; sun YH et al, cell Res.2018;28:779-81; toure M.et al, angew Chem Int Ed Engl.2016;55 (6); 1976); 1973). And have been disclosed or discussed in the patent publications, e.g. US20160045607, US20170008904, US20180050021, US20180072711, WO2002020740, WO2014108452, WO2016146985, WO2016149668, WO2016149989, WO2016197032, WO2016197114, WO2017011590, WO2017030814, WO2017079267, WO2017182418, WO2017197036, WO2017197046, WO2017197051, WO2017197056, WO2017201449, WO2017211924, WO2018033556, WO2018071606.

Prostate cancer (PCa) remains the leading cause of cancer-related death in north american men (S.M.Green, mol.Cell.Endocrinol.360 (2012) 3-13). The main driving factor for this disease is the Androgen Receptor (AR), a steroid-induced transcription factor, which regulates many genes that promote tumor growth (N.Lallous, int.J.Mol.Sci.14 (2013), 12496-12519). AR is part of the nuclear receptor family, consisting of an N-terminal domain (NTD), followed by a DNA Binding Domain (DBD) and a C-terminal Ligand Binding Domain (LBD) (G.Jenster, mol.Endocrinol.5 (1991) 1396-1404). The binding signaling nuclear localization of steroids to LBD followed by DBD-mediated AR dimerization and binding of activated receptor dimers to Androgen Response Elements (ARE) on the target gene. Currently used AR antagonists, such as enzalutamide, block AR activation by interfering with the binding of steroids to the androgen binding pocket on LBD (C.E.Bohl, J.Biol.Chem.280 (2005) 37747-37754). Resistance occurs when mutations in the binding pocket render these drugs ineffective, or by expressing constitutively active splice variants (e.g., AR-V7, 6-9) that lack LBD entirely. Despite the improvement in medical treatment over the past 30 years, prostate cancer (PCa) remains an important cause of cancer-related death, next to lung cancer in men in developed countries (Hamdy, F.C.; N.Engl. J.Med.2016,375,1415-1424; litwin, M.S.; J.Am. Med. Assoc.2017,317, 2532-2542). In addition to surgery and radiation therapy, androgen Deprivation Therapy (ADTs) is a first line treatment for patients with high risk local disease of prostate cancer, and second generation antiandrogens such as abiraterone and enzalutamide have been shown to be beneficial in advanced prostate cancer patients (Karantanos, T.; oncogene 2013,32,5501-5511; harris, WP, nat. Clin. Practice. Neurol.2009,6, 76-85.). However, patients who progress to metastatic castration-resistant prostate cancer (mCRPC), a hormone-resistant disease, are subject to high mortality, and there is currently no cure (Narayanan, r.; oncoscience 2017,4,175-177; croder, cm; endocrinology 2018,159,980-993). Androgen Receptor (AR) and its downstream signaling play a critical role in the development and progression of localized and metastatic prostate cancer. (sundecn, h.; previous strategies for successful targeting of AR signaling have focused mainly on blocking androgen synthesis by drugs (such as abiraterone) and on blocking androgen synthesis by AR antagonists (such as enzalutamide and apaluramide (ARN-509)) (Oksala, r.; steroid biochem.mol.biol.2018; watson, pa., nat.Rev.cancer 2015,15,701-711; guo, C.; J.Med.chem.2011,54,7693-7704.; guerrini, A.; J.Med.chem.2014,57,7263-7279.Jung, M.E, J.Med.chem.2010,53,2779-2796, yamamoto, S.; bioorg. Medical chemistry 2012,20,2338-2352.) however, these drugs became ineffective in advanced prostate cancer with AR gene amplification, mutation and alternate splicing (Lottrup, G.; J.Clin.Endocrinol.2013, 98, 2223-9) however, it was apparent that in most CRPC patients, AR protein continued expression, the tumor still relied on the AR signal and thus the target for AR signaling (CRP.21, 35, 35.g.; mu.35, 35).

The compounds of the invention are more potent new AR antagonists than known AR antagonists and antagonize AR by alternative strategies, for example, by degradation of AR. The present application addresses this need.

"diastereoisomers" refers to stereoisomers of a compound having two or more chiral centers that are not mirror images of each other. Mixtures of diastereomers can be separated into their individual diastereomers based on their physical or chemical differences by methods well known to those skilled in the art, such as by chromatography and/or fractional crystallization. Enantiomers can be separated into the corresponding pure enantiomers by reaction with a suitable optically active compound (e.g., a chiral auxiliary such as a chiral alcohol or Mosher acid chloride) to convert the enantiomeric mixture into a diastereomeric mixture, separate the diastereomers, and convert (e.g., hydrolyze) the individual diastereomers. Enantiomers and diastereomers may also be separated by use of a chiral HPLC column.

Single stereoisomers, such as substantially pure enantiomers, may be obtained by resolution of the racemic mixture using methods such as the formation of diastereomers using optical resolution agents (Eliel, e. And Wilen, s.stephaochemistry of Organic compounds, new york: john Wiley & Sons, inc., 1994; lochmiller, CH et al "chromatographic resolution of enantiomers: selectivity review". J.chromatogrj., 113 (3) (1975): pages 283-302) the racemic mixture of the chiral compounds of the invention may be separated and isolated by any suitable method, including: (1) forming ions, diastereomeric salts with chiral compounds and separating by fractional crystallization or other methods, (2) forming diastereomeric compound derivatizing reagents with chiral compounds, separation of diastereomers and conversion to pure stereoisomers, and (3) directly separating the substantially pure or enriched stereoisomers under chiral conditions.
