阿塔瓜瓜产品是Ataciguat is an anthranilic acid derivative that activates the oxidized (heme-free) form of soluble guanylate cyclase (sGC) (EC₅₀= 0.5-10 µM in purified bovine lung or crude human corpus cavernosum isolates) by binding to the heme pocket and mimicking its function. It has been shown to increase cGMP levels in cultured rat aorta smooth muscle cells and to induce vasorelaxation of isolated rat aorta, porcine coronary arteries, and human corpus cavernosum (EC₅₀ = 1-10 µM).
