AI Technical Summary
Current therapies for castration-resistant prostate cancer (CRPC) targeting the androgen receptor (AR) face significant challenges due to drug resistance, including mutations in the AR ligand binding domain, AR amplification/overexpression, and the presence of constitutively active AR variants like AR-V7, which are not effectively addressed by existing AR-directed therapies.
Development of novel bifunctional compounds that act as degraders of AR variants, specifically targeting the N-terminal domain (NTD) of the AR, utilizing a targeting protein warhead (TPW), a linker (L), and an E3 ligase binder (U) to degrade aberrant AR proteins, thereby inhibiting their activity.
These compounds potentially overcome resistance to current therapies by effectively degrading AR proteins, including full-length AR and AR variants, offering a broader range of inhibition and improved therapeutic outcomes for CRPC.

COMPOUNDS FOR THE TARGETED DEGRADATION OF ANDROGEN RECEPTOR AND USE THEREOFBACKGROUND OF THE INVENTION
[0001] Prostate cancer (PCa) is the second most diagnosed cancer and the fifth leading cause of cancer death among men worldwide, with an estimated 1,414,000 new cancer cases and 375, 304 deaths in 2020. Prostate cancer (PCa) is the most frequently diagnosed cancer in 112 countries, and the leading cause of cancer death in 48 countries. It is worth noting that the burden of prostate cancer is expected to increase owing to the population aging and economic growth (Le Wang et. al., Front Public Health, 2022 Feb. 16 (10) , 811044) .
[0002] Although the prognostics and treatment of PCa would generally achieve good outcome with surgical prostate castration to remove major androgen supply when the cancer is constrained to the prostate, about 20%of patients will progress to a more devastating metastatic stage of PCa. Data suggest that 10-20 %of patients with PCa develop castration-resistant prostate cancer (CRPC) within five years of follow-up and that the median survival since the development of castration resistance is approximately 14 months (range 9-30) , which is associated with continuous androgen receptor (AR) signaling even in the absence of androgen (André Mansinho et. al., Adv. Exp. Med. Biol. 2018: 1096: 117-133) .
[0003] Currently, widely used AR-directed therapies, such as abiraterone acetate (Zytiga) and enzalutamide (Xtandi) , which target androgen synthesis or AR hormone binding pocket (AR-HBP) , provide only a modest 3 to 5-month survival benefit for patients with mCRPC. However, the development of acquired resistance will occur in nearly all patients with CRPC, even those who initially benefit from hormonal therapy. Multiple possible mechanisms for resistance development have been identified, among which the mutations in the AR ligand binding domain (LBD) , AR amplification / overexpression, AR splice variants (AR-Vs) expression, and intra-tumoral de novo synthesis of androgens have been broadly observed in the clinic. Novel anti-AR drug is urgently required to overcome the drug resistance caused by the current anti-AR agents for patients with CRPC.
[0004] Notably, the AR N-terminal domain (NTD) is considered the “Achilles Heel” of AR, essential for AR activity regardless of the presence of androgen. Numerous AR variants (AR-Vs) , which miss LBD as the result of transcription splicing, have been identified in PCa cells and patients. Remarkably, these variants are constitutively active because of the removal of otherwise inhibitory LBD, and some of them (e.g. AR-V7) are negatively correlated with AR-directed therapy outcome in patients. Pharmacologically, AR-NTD inhibitors can potentially affect a broader range of AR proteins, such as full-length AR (AR-FL) , AR mutants and AR-Vs. Although AR-NTD are intrinsically disordered proteins (IDPs) due to possessing few α-helices and β-sheets, making structure-based drug design difficult, the discovery of AR-NTD inhibitors is still underway, such as the investigational new drug EPI-7386 (Clinical phase II) , which displayed preliminary potential to overcome resistance encountered by current therapies. A review focusing on recent advances in drug research targeting AR-NTD for treating CRPC can be found [Yang Ji et. al., European Journal of Medicinal Chemistry Volume 247, 5 February 2023, 115077] .
[0005] Herein, we report the discovery of a number of new compounds that can act as a degrader of alternatively spliced form of AR such as AR-V7. These novel bifunctional molecules represent a new step toward the development of drugs that may overcome resistance derived from the current therapies.SUMMARY OF THE INVENTION

[0716] Biological Assay:
[0717] Protein degradation assay
[0718] The traditional western blotting (WB) or in-cell western assay were performed to analyze compounds' degradation activity on AR (-FL and-V7) in 22Rvl cells.
[0719] For traditional WB, 1.5 million 22Rvl cells were inoculated in a 6-well tissue culture plate and grew overnight before being treated with 100 or 1000 nM compounds for another 24 hours. The treated cells were digested with lysis buffer and released protein were quantified in BCA assay, separated on an SDS-PAGE and detected by antibodies recognizing AR-NTD (CST#5153) with β-actin as internal reference.
[0720] For in-cell western assay, 6000 22Rvl cells were inoculated in a 96-well black transparent tissue culture plate and grew overnight before being treated with serial-diluted compounds for 16-24 hours. The levels of AR-V7 in the treated cells were detected with AR-V7 specific antibody (Abcam #Ab273500) , normalized by total cell numbers as reflected by DNA staining, read out by two channels of fluoresce density simultaneously on a LI-COR Odessey DLx imager. The data is analyzed using the 5-parameter dose-response equation in Prism software (GraphPad) , and the DC50 and Dmax values are calculated.
[0721] Table II below provides the biological assay data. Wherein “A” means the value< 50 nM, “B” means 50 nM < the value < 500 nM, “C” means 500 nM < the value < 5000 nM, and “D” means the value >5000 nM, in which, the value means DC50 or IC50. (NT means not tested.)

[0723] Cell proliferation assay
[0724] Compounds' effect on cell viability were performed on cancer cell lines including LNCap, VCap, 22Rv1, DU-145 and OVCAR3 cells with Assay (Promega#G7570) .
[0725] 1000-6000 cells were inoculated in a 96-well black transparent tissue culture plate, grew overnight to 15-20% confluency, treated with serial-diluted compounds for 4-6 days. Viability of the treated cells were quantified by their ability to catalyze CTG substrate for luminesce signal, as recorded on a Spectramax iD3 plate reader. The data is analyzed using the 5-parameter dose-response equation in Prism software (GraphPad) , and the IC50 and Emax values are calculated.
[0726] Below table III provides the proliferation data. Wherein “A” means the value< 50 nM, “B” means 50 nM < the value < 500 nM, “C” means 500 nM < the value < 5000 nM, and “D” means the value >5000 nM, in which, the value means DC50 or IC50. (NT means not tested.)
