| Bioactivity | Vardenafil is a selective and orally active inhibitor of phosphodiesterase-5 (PDE5), with an IC50 of 0.7 nM. Vardenafil shows inhibitory towards PDE1, PDE6 with IC50s of 180 nM, and 11 nM, while IC50s are >1000 nM for PDE3 and PDE4[1]. Vardenafil competitively inhibits cyclic guanosine monophosphate (cGMP) hydrolysis and thus increases cGMP levels[2]. Vardenafil can be used for the research of erectile dysfunction, hepatitis, diabetes[1]-[6]. |
| Invitro | Vardenafil specifically inhibits the hydrolysis of cGMP by PDE5 with an IC50 of 0.7 nM[1].Vardenafil increases intracellular cGMP levels in the cavernosum tissue of the penis, thus results increasing the dilation of the body's sinuses and blood flow[3]. |
