One resistance mechanism is point mutations in the ligand binding domain of AR that can transform antagonists into agonists. The AR F877L mutation, identified in patients treated with enzalutamide or apalutamide, confers resistance to both enzalutamide and apalutamide. Compound 4 (JNJ-pan-AR) was identified as a pan-AR antagonist with potent activity against wild-type and clinically relevant AR mutations including F877L. Metabolite identification studies revealed a latent bioactivation pathway associated with 4. Subsequent lead optimization of 4 led to amelioration of this pathway and nomination of 5 (JNJ-63576253) as a clinical stage, next-generation AR antagonist for the treatment of castration-resistant prostate cancer (CRPC).Publication metadataAuthor(s): Zhang Z, Connolly PJ, Lim HK, Pande V, Meerpoel L, Teleha C, Branch JR, Ondrus J, Hickson I, Bush T, Luistro L, Packman K, Bischoff JR, Ibrahim S, Parrett C, Chong Y, Gottardis MM, Bignan GPublication type: ArticlePublication status: PublishedJournal: Journal of Medicinal ChemistryYear: 2021Volume: 64Issue: 2Pages: 909-924Print publication date: 28/01/2021Online publication date: 20/01/2021Acceptance date: 07/09/2020Date deposited: 26/03/2021ISSN (print): 0022-2623ISSN (electronic): 1520-4804Publisher: American Chemical SocietyURL: DOI: 10.1021/acs.jmedchem.0c01563AltmetricsShare
