Vardenafil HCl Trihydrate是一种新型PDE抑制剂,作用于PDE5和PDE1,IC50分别为0.7和180 nM。
Information
Vardenafil HCl Trihydrate (BAY38-9456) is a new type PDE inhibitor with IC50 of 0.7 and 180 nM for PDE5 and PDE1, respectively.
In vitro
Vardenafil specifically inhibits the hydrolysis of cGMP by PDE5 with an IC50 of 0.7 nM (6.6 nM). Vardenafil significantly enhances the SNP-induced relaxation of human trabecular smooth muscle at 3 nM (10 nM). Vardenafil also significantly potentiates both ACh-induced and transmural electrical stimulation-induced relaxation of trabecular smooth muscle. Vardenafil (100 mM) increases cyclic GMP levels in rat hippocampal slices. Vardenafil, tadalafil, and Sildenafil each competitively inhibit cGMP hydrolysis by phosphodiesterase-5 (PDE5), thereby fostering cGMP accumulation and relaxation of vascular smooth muscle.
In vivo
Vardenafil dose-dependently potentiates erectile responses to intravenously administered sodium nitroprusside in rabbit. [1] Vardenafil (3 mg/kg, p.o.) results in an improved object discrimination performance in rats. Vardenafil (30 mg/L, p.o.) increases both iNOS and proliferating cell nuclear antigen expression (SM cell replication) in rats, with normalization of the dynamic infusion cavernosometry drop rate and SM/collagen ratio. Vardenafil induces powerful preconditioning-like cardioprotective effect against ischemia/reperfusion injury through opening of mitochondrial K(ATP) channels in the heart of rabbit. Vardenafil protects the ischemic myocardium against reperfusion injury through a mechanism dependent on mitochondrial K(ATP) channel opening.
