ARV-110 is an androgen receptor PROTAC degrader. It promotes ubiquitination and degradation of the androgen receptor.
ARV-110 is a PROteolysis TArgeting Chimera (PROTAC) protein degrader that recruits the cereblon-containing E3 ubiquitin ligase to direct the polyubiquitination and subsequent proteasomal degradation of AR. It selectively degrades wild-type AR and most clinically relevant mutants with low nanomolar potency.
Bavdegalutamide (ARV-110) is an orally active, specific androgen receptor (AR) PROTAC degrader. Bavdegalutamide promotes ubiquitination and degradation of AR. Bavdegalutamide can be used for the research of prostate cancer (Pink: AR ligand (HY-168299); Blue: E3 ligase ligand (HY-W093272); Black: linker (HY-W091986))[1].
Bavdegalutamide (oral gavage; 1 mg/kg; QD) exhibits a greater than 90% AR degradation in vivo. In LNCaP, VCaP and prostate cancer patient derived xenograft (PDX) models, Bavdegalutamide also exhibits significant inhibition of tumor growth and AR signaling[2].Bavdegalutamide (oral gavage; 3 or 10 mpk; 30 days) demonstrates in vivo efficacy and reduction of AR-target gene expression in a long term, castrate, enzalutamide-resistant VCaP tumor model. The TGI are 70% and 60% for 3 mpk and 10 mpk dosage. Respectively[2].
