Hydroxyhomo Sildenafil is an analog of Sildenafil (sc-338584). Hydroxyhomo Sildenafil serves as a tool for studying the biochemical and pharmacological properties of PDE5 inhibitors. It allows researchers to compare its effects with those of Sildenafil, enhancing our understanding of how structural differences influence binding affinity and enzyme inhibition.
