Ataciguat 是一种不依赖一氧化氮的可溶性鸟苷酸环化酶 (sGC) 激活剂，具有血管舒张作用。它能够激活 sGC 的铁血红素铁氧化还原形式，刺激 cGMP 的产生。

Ataciguat (HMR-1766) is a potent and specific soluble guanylate cyclase (sGC) activator.

Ataciguat induces the relaxation in aortic rings or coronary rings. In the presence of nitric oxide synthase (NOS) inhibitor, the endothelium effect was abolished to DETA-NO or ataciguat, in both vessels. Ataciguat was able to induce NO production in HUVECs cells. In the presence of NOS inhibitor, the NO production induced by ataciguat was abolished[1].
