Primary TargetPDE5

General description

A cell-permeable, brain permeant, quinoline-based compound that acts as a highly potent and selective inhibitor of phosphodiesterase 5 (PDEV; IC₅₀ = 270 pM). Exhibits over 10,000 fold greater selectivity over various other phosphodiestrases and trivial activity against PDE VI (IC₅₀ = 339 nM). Shown to increase cGMP levels in mouse hippocampus and attenuates long term potentiation and memory defects in mice with elevated levels of oligomeric Aβ42. It is rapidly absorbed with peak plasma concentration observed at 30 min. Displays desirable pharmacokinetic properties with plasma t1/2 = 1.33 h and brain t1/2 = 1.04 h.
