Vardenafil-d5

Vardenafil-d5 is deuterium labeled Vardenafil. Vardenafil is a selective, orally active, potent inhibitor of phosphodiesterase-5 (PDE5), with an IC50 of 0.7 nM. Vardenafil shows selectivity over PDE1 (180 nM), PDE6 (11 nM), PDE2, PDE3, and PDE4 (>1000 nM). Vardenafil competitively inhibits cyclic guanosine monophosphate (cGMP) hydrolysis and thus increases cGMP levels. Vardenafil can be used for the research of erectile dysfunction[1][2].
