(S)-Methylisothiourea sulfate is a potent, selective and competitive inhibitor of the inducible nitric oxide synthase (iNOS). Nitric oxide synthases, composed of the constitutive and the inducible isoforms, are a family of enzymes responsible for catalyzing the production of nitric oxide (NO) from L-arginine. The inducible isoform, i.e. iNOS, can be induced in various cells, including macrophages, by a variety of agents such as endotoxin, and thereby produces NO as an immune defense mechanism. Enhanced NO formation has been implied in the pathophysiology of a variety of diseases, such as circulatory shock. Thus, (S)-methylisothiourea sulfate, as a selective iNOS inhibitor, may have considerable value in the therapy of circulatory shock of various etiologies and other pathophysiological conditions associated with induction of iNOS.

Cell lines | J774.2 macrophages and rat aortic vascular smooth muscle cells |
Reaction Conditions | 100 nM ~100 μM (S)-methylisothiourea sulfate |
Applications | In J774.2 macrophages and rat aortic vascular smooth muscle cells, (S)-methylisothiourea sulfate exhibited more potent inhibitory effects on lipopolysaccharide (LPS)-induced nitrite production than any other known inhibitor of NOS, such as NG-amino-L-arginine. |
