| Bioactivity | Dutasteride (GG745) is a potent inhibitor of both 5α-reductase isozymes. Dutasteride may possess off-target effects on the androgen receptor (AR) due to its structural similarity to DHT[1]. | ||||||||||||
| Invitro | Dutasteride inhibits 3H-T conversion to 3H-DHT and, as anticipated, inhibits T-induced secretion of PSA and proliferation. However the drug also inhibited DHT-induced PSA secretion and cell proliferation (IC50 approximately 1 μM)[1]. Dutasteride competes for binding the LNCaP cell AR with an IC50 approximately 1.5 μM. High concentrations of dutasteride (10-50 μM), but not finasteride, in steroid-free medium, resulted in enhanced cell death, possibly by apoptosis[1]. Dutasteride reduces cell viability and cell proliferation in both cell lines tested (androgen-responsive (LNCaP) and androgen-unresponsive (DU145) human prostate cancer (PCa)) [2]. | ||||||||||||
