Biological Activity for Cl-4AS-1

Cl-4AS-1 is a potent steroidal androgen receptor agonist (IC50 = 12 nM). Mimics the action of 5α-dihydrotestosterone (DHT). Transactivates the mouse mammary tumor virus (MMTV) promoter; represses MMP1 promoter activity. Inhibits 5α-reductase type I and II (IC50 values are 6 and 10 nM respectively).
