AR Degrader-3

AR Degrader-3 is an orally active molecular glue that targets AR/ARV7 and induces the degradation of AR and ARV7 through the ubiquitin-proteasome pathway (UPP). AR Degrader-3 directly interacts with the ligand-binding domain (LBD) and the N-terminal domain (NTD) of AR. AR Degrader-3 effectively suppresses the transcriptional activity of wild-type AR (AR-WT), AR mutants, and ARV7. AR Degrader-3 downregulates the mRNA and protein levels of downstream AR target genes, thereby overcoming antiandrogen resistance mediated by ARV7 and AR point mutations. AR Degrader-3 induces apoptosis in Enzalutamide (ENZa) -resistant cells and increases cleaved caspase-3 protein levels. AR Degrader-3 can be used for the study of castration-resistant prostate cancer (CRPC).
