Popis: Abstract.: This study was performed to investigate the mechanisms involved in the vasorelaxation induced by mesoionic 2-(4-chlorophenyl)-3-methyl-4-(4-methoxyphenyl)-1;3-thiazolium-5-thyolate (CMMTT), a newly synthesized mesoionic compound, in rat superior mesenteric arteries. In phenylephrine (10 μM)–pre-contracted mesenteric rings, CMMTT (10−14 –10− 6 M) induced a concentration-dependent relaxation [pD2 = 10.26 ± 0.05, Emax = 80.8 ± 5.8%], and this effect was almost abolished after either removal of the vascular endothelium [Emax = 17.7 ± 4.2%, P
