Hydroxythiohomo Sildenafil is a thio analog of Sildenafil which has been reported to be a PDE5 inhibitor. Sildenafil is a selective inhibitor of type 5 cGMP phosphodiesterase (PDE5), which catalyzes teh hydrolysis of cGMP, an important secondary messenger molecule in a variety of cellular processes. Sildenafil has been reported to enhance angiogenesis in rat models of stroke and also has been reported to be a mild vasodilator. Sildenafil has been shown to prevent indomethacin-induced small intestinal ulceration formation throuh an NO/cGMP-dependent mechanism.
