Relaxation responses induced by MEPY in endothelium-intact rat aortic rings pre-contracted with phenylephrine (PE, 1 μM) in the presence or absence (control) of glibenclamide (10 μM), tetraethylammonium (TEA, 5 mM), or 4-aminopyridine (4-AP, 1 mM) in Krebs-Henseleit solution. The relaxant effects of MEPY on isolated rat aortic rings were calculated as a percentage of the contraction in response to PE. Values are expressed as mean ± SEM (n = 6–8).
