| 产品描述 | IC50: 65 M L-NIO dihydrochloride is an inhibitor of nitric oxide (NO) synthase (iNOS, eNOS and nNOS). An NO synthase is inducible by immunological stimuli such as endotoxin (LPS) and various cytokines, generating nitric oxide (NO) in phagocytic cells including neutrophils and macrophages. Generation of NO by macrophages has been revealed to kill tumour cells due to the inactivation of ironsulphur centres of mitochondrial enzymes. In vitro: To protect against inflammatory injury stimulated by activated neutrophils, the ability of L-arginine (N-iminoethyl-L-ornithine (L-NIO) was studied in rats, following intradermal or intrapulmonary deposition of immune complexes [1]. The protective effect of L-NIO in the skin was reversed in a dose-dependent manner by the presence of L-arginine, rather than by D-arginine. The protective effects of L-NIO L-Arginine were reversed also in immune complex-induced lung injury, and not associated with reductions in neutrophil accumulation as measured by extraction from tissues of myeloperoxidase. The results demonstrate immune complex induced vascular injury induced by activated macrophage was inhibited effectively by L-NIO as a potent inhibitor [1]. In vivo: A dose-dependent increase in mean systemic arterial blood pressure accompanied by bradycardia was induced at the administration of L-NIO (0.03-300 mgkg-1, i.v.). L-NIO (100 mgkg-, i.v.) has an effect inhibitor of the hypotensive responses to ACh and bradykinin. L-arginine (30-100 mg kg- 1, i.v.) in a dose-dependent manner reversed the increase in blood pressure and bradycardia produced by these compounds. It was enantiomer specific for all of these effects. These facts indicate that L-NIO can inhibit NO synthase as inhibitors in the vascular endothelium and verify that L-NIO plays an important role for NO synthesis in the maintenance of vascular tone and blood pressure [2]. Clinical trial: So far, no clinical study has been conducted. References: |
