Biological Activity
VPC-14449 is a potent and selective inhibitor of the DNA-binding domain of the androgen receptor (AR-DBD), with IC50 of 0.34 μM for full-length human AR. VPC-14449 reduces the ability of full-length AR as well as AR variants to interact with chromatin. VPC-14449 can be used for the research of prostate cancer[1][2].
VPC-14449 (0.01-100 μM; 24 h) inhibits AR-transcriptional activity and cell viability in LNCaP, C4-2, MR49F, and 22Rv1 cells[2].VPC-14449 (0.01-100 μM; 24 h) dose-dependently inhibits the transiently expressed full-length human AR in PC3 cells (IC50=0.34 μM) without affecting AR protein expression[1].
VPC-14449 (100 mg/kg; i.p. twice daily for 4 weeks) reduces tumor volume and abolishes PSA production with no decrease in body weight over a total duration 4 weeks in LNCaP xenograft model[1].
