产品描述 | NG,NG-dimethyl-L-Arginine dihydrochloride is an endogenous nitric oxide synthase inhibitor. Nitric oxide (NO) that is synthesised from L-arginine contributes to the regulation of blood pressure and to host defence[1]. |
体外活性 | NG,NG-dimethyl-L-Arginine (ADMA) was found to be able to inhibit macrophage and vascular NO synthase. When added to a cytosolic preparation of macrophage NO synthase, ADMA could cause dose-dependent inhibition of NO formation. In the presence of added arginine, ADMA could inhibited NO synthesis and the inhibitory effects of ADMA were prevented by addition of L-arginine so that the rate of NO synthesis did not significantly differ from control values [1]. |
体内活性 | Animal study showed that the injection of 1-30 mg/kg ADMA into 3 anaesthetised guineapigs could cause dose-dependent increases in mean arterial blood pressure. Moreover, during continuous infusion of ADMA, which caused plasma ADMA concentrations to rise approximately 9-fold, the systolic blood pressure was raised by nearly 15 % [1]. |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
