生物活性

製品説明 Silodosin (KAD 3213, KMD 3213) is a highly selective α1A-adrenoceptor antagonist, used in treatment of benign prostatic hyperplasia.
in vitro Silodosin shows higher selectivity for the alpha(1A)-AR subtype than tamsulosin hydrochloride, naftopidil or prazosin hydrochloride (affinity is highest for tamsulosin hydrochloride, followed by silodosin, prazosin hydrochloride and naftopidil in that order). [1] Silodosin and tadalafil have synergistic inhibitor effects on nerve-mediated contractions of human and rat isolated prostates in rats. [2]
in vivo Silodosin strongly antagonizes noradrenaline-induced contractions in rabbit lower urinary tract tissues (including prostate, urethra and bladder trigone, with pA(2) or pKb values of 9.60, 8.71 and 9.35, respectively). [1] Silodosin significantly inhibits the phenylephrine-induced increase in intraurethral pressure (versus the vehicle-treated group) at 12 hours, 18 hours, and 24 hours after its oral administration in rats. [3] Silodosin (0.1-0.3 mg/kg) or prazosin (0.03-0.1 mg/kg) reduces obstruction-induced increases in intraluminal ureter pressures by 21-37% or 18-40% respectively. Silodosin inhibits contractions of the rat and human isolated ureters and has excellent functional selectivity in vivo to relieve pressure-load of the rat obstructed ureter. [4] Silodosin (0.3-300 mg/kg) dose-dependently inhibits the hypogastric nerve stimulation-induced increase in intraurethral pressure (without significant hypotensive effects) in both young and old dogs with benign prostatic hyperplasia.
