A031
A031 is a PROTAC degrader targeting the androgen receptor. A031 induces time-dependent degradation of androgen receptor protein. A031 exerts tumor growth inhibitory effects in a zebrafish model xenografted with human prostate cancer cells. A031 can be used in studies related to prostate cancer.

Biological Activity
A031 (0.125-1.0 μM; 4 days) potently inhibits AR-positive human prostate cancer VCaP cell viability with an IC50 of less than 0.25 μM and achieves a 69.56% inhibition rate at 1.0 μM after 4 days of treatment[1].
A031 (2.0 μM; 2-4.5 h) induces time-dependent degradation of AR protein in AR-positive human prostate cancer VCaP cells, with near-complete degradation observed after 4.5 h of treatment with 2.0 μM A031[1].
A031 (2.0 μM) acts as a bona fide AR degrader in AR-positive human prostate cancer VCaP cells, as its AR-degrading activity is blocked by proteasome and NEDD8 pathway inhibitors but not by VHL-3 pre-treatment[1].
