Biological Activity for Prazosin hydrochloride

Prazosin hydrochloride is an α1 and α2B-adrenoceptor antagonist. Also a potent antagonist at the melatonin MT3 receptor (Ki = 10.2 nM). In prostate cancer cells, Prazosin induces DNA damage stress, Cdk1 inactivation, G2 checkpoint arrest and apoptosis. In mice bearing prostate cancer xenografts, oral administration of Prazosin reduces tumor mass.
