Product Description
NO-independent activator of soluble guanylyl cyclase (sGC) [1,2]. Activates both isoforms α1β1 and α1β2 of sGC [3]. While the related compound YC-1 (Prod. No. ALX-420-025) also acts as a non-specific phosphodiesterase inhibitor, BAY 41-2272 has no effect on phosphodiesterases. Stimulation of sGC is not blocked by high concentrations of NO scavengers (e.g. PTIO, Prod. No. ALX-430-007) and the combination of  BAY 41-2272 with the NO donor DEA NONOate (Prod. No. ALX-430-034) potentiates the activation of sGC. Although BAY 41-2272 alone is not as strong a stimulator of sGC as NO, concentrations as low as 10-100nM stimulate sGC to a level that would be expected to cause biologically important increases in cGMP [1]. ODQ (Prod. No. ALX-270-034), a potent and selective inhibitor of sGC, completely inhibited the effect of BAY 41-2272 [1]. The activity of BAY 41-2272 is described in selected literature references [4-6].
