Description
An α1B-AR antagonist (Ki = 0.45 nM for the recombinant human receptor); selectively inhibits α1B-ARs over α1A-, α1D-, and α1L-ARs (Kis = 7.59, 10.23, and 49 nM, respectively); inhibits norepinephrine-induced contractions of isolated rabbit prostate and urethral strips (Kis = 100 and 316.2 nM, respectively), and reduces norepinephrine-induced contractions of chloroethylclonidine-precontracted isolated rabbit aortic rings (Ki = 50 nM); decreases diastolic blood pressure (ED25 = 183 µg/kg, i.v.) and increases intracavernous pressure in anesthetized dogs when administered intracavernously at 30-1,000 µg/kg
