生物活性
VPC-14449 is a potent and selective inhibitor of the DNA-binding domain of the androgen receptor (AR-DBD), with IC 50 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.

IC50 & Target[1][2]
IC50: 0.34 μM (AR-DBD)
体外研究(In Vitro)
VPC-14449 (0.01-100 μM; 24 h) inhibits AR-transcriptional activity and cell viability in LNCaP, C4-2, MR49F, and 22Rv1 cells.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. has not independently confirmed the accuracy of these methods. They are for reference only.Cell Viability Assay
体内研究(In Vivo)
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. has not independently confirmed the accuracy of these methods. They are for reference only.
