Description

General description

A cell-permeable thiotriazolopyrimidine compound that acts as an effective NADPH oxidase (NOX) inhibitor (IC₅₀ = 10.6 µM against NOX activity in human neutrophil lysates) and is widely used for studying NOX-dependent cellular ROS formations in various cultures, including oxLDL-treated HUVEC (complete inhibition at 5 µM), PDGF-induced primary rat VSMC (vascular smooth muscle cells; complete inhibition at 10 µM), as well as aortic sections from spontaneously hypertensive rats (72% inhibition at 10 µM) ex vivo.

Also shown to inhibit PDGF-BB-induced murine EB (embryonid body) vacularization (74% inhibition at 50 µM) and improve ACh-induced vasorelaxation of isolated rat aortic rings from both SHRs and non-hypertensive rats ex vivo (by 41.7 and 34.5%, respectively, at 10 µM).
