生物活性

S-Methylisothiourea sulfate is a potent, selective and competitive inhibitor of inducible nitric oxide synthase (iNOS). S-Methylisothiourea sulfate exerts beneficial effects in rodent models of septic shock.

体外研究

S-Methylisothiourea sulfate is a competitive inhibitor of iNOS activity at the L-arginine site.
S-Methylisothiourea sulfate prevents the NO-mediated cytotoxic effect of LPS in cultured macrophages.
S-Methylisothiourea sulfate (100 nM-100 μM) exhibits inhibitory effects on LPS (ug/mL)-induced nitrite production in J774.2 macrophages and rat aortic vascular smooth muscle cells.
S-Methylisothiourea sulfate (up to 1 mM) does not inhibit the activity of xanthine oxidase, diaphorase, lactate dehydrogenase, monoamine oxidase, catalase, cytochrome P450, or superoxide dismutase.

体内研究

S-Methylisothiourea sulfate (0.01-3 mg/kg; i.v.) dose-dependently reverses the hypotension and the vascular hyporeactivity to vasoconstrictor agents caused by endotoxin LPS in anesthetized rats.
S-Methylisothiourea sulfate (5 mg/kg; i.p.; given 2 hr after LPS; 10 mg/kg; i.p.) attenuates the rises in plasma alanine and aspartate aminotransferases, bilirubin, and creatinine and also prevents hypocalcaemia when measured 6 hr after administration of LPS.
S-Methylisothiourea sulfate (1 mg/kg; i.p.) improves 24-hr survival of mice treated with a high dose of LPS (60 mg/kg; i.p.).

Animal Model: Male Wistar rats (260-320 g)
Dosage: 0.01 mg/kg, 0.1 mg/kg, 1 mg/kg, 3 mg/kg
Administration: Intravenous injection
Result: Caused a prompt restoration of the blood pressure to pre-LPS levels at 3 mg/kg dose in LPS (10 mg/kg, i.v.)-treated rats; Inhibited iNOS activity measured in homogenates of lung.
