Ataciguat (HMR-1766) is a nitric oxide-independent soluble guanylate cyclase (sGC) activator. Ataciguat is able to activate the ferric heme-iron redox form of sGC that stimulate the production of cyclic GMP (cGMP). Ataciguat exhibits vasodilator effects[1][2][3].

In Vitro	Ataciguat (1-100 μM) induces the relaxation in aortic rings or coronary rings[2]. Ataciguat (0.1-10 μM; 30 min) increases NO production in HUVEC cells[2]. Ataciguat (1 nM-100 μM) induces concentration-dependent relaxations in sphincter of Oddi (SO) rings pre-contracted by Carbachol[3].
