Background

Dutasteride?(Avodart) is an inhibitor of dual 5-alpha-reductase for treating benign prostatic hyperplasia (BPH).

Dutasteride has been reported to inhibit conversion of?3H-testosterone to?3H-DHT by more than 99% in LNCaP cells. Dutasteride strongly reduces growth, proliferation, and viability of LNCaP cells as well. Dutasteride increased the enzymatic activities of caspase 7 and caspase 8 dose-dependently at 48 hours, providing functional significance and confirming that the?apoptotic and survival pathways are being activated by dutasteride treatment in LNCaP cells [1].

In vivo, dutasteride, which inhibits both 5αR1/5αR2, is efficacious in blocking prostate cancer development or progression in C57BL/6 TRAMP x FVB mice [2].
