Discovery and biological evaluation of darolutamide derivatives as inhibitors and down-regulators of wild-type AR and the mutants

Androgen receptor (AR) has been a target of prostate cancer (PC) for nearly six decades. Recently, downregulating or degrading AR and the mutants especially the splice variant 7 (AR-V7) lacking ligand binding domain (LBD) emerged as an advantageous therapeutic approach to overcome drug resistance. Here, the structural modification of darolutamide resulted in the discovery of dual-action AR inhibitors and down-regulators. Unlike other traditional AR antagonists targeting the AR-LBD, compounds 4k and 4b not only inhibit the activities of wt-AR and AR-F876L mutant but also downregulate the protein expression of full-length (AR-full) and AR variant 7 (AR-V7) at mRNA level. In cell proliferation assays, compounds 4k and 4b exhibited better antiproliferative activities than darolutamide and enzalutamide against AR-V7-positive 22Rv1 cells and VCaP cells. In addition, 4k demonstrated better antitumor activity than clinically used enzalutamide in castration-resistant VCaP xenograft model. Collectively, combining the activities of AR inhibition and downregulation, compound 4k is proposed as an advantageous lead compound to disrupt AR signaling and overcome resistance.
