产品描述 | 7-Nitroindazole is a non-selective inhibitor of NOS isoforms in vitro for neuronal nitric oxide synthase showing a 10-fold selectivity for neuronal NOS. |
体内活性 | In the experimental model of cocaine multiple administration in rats the selective nNOS inhibitor 7-nitroindazole not only attenuated the behavioral changes induced by cocaine deprivation but also exerted an antioxidant and neuroprotective activity.?The possible mechanisms underlying the neuroprotective effects of 7-NI could be due to the combination of its inhibitory effect of nNOS and its direct free radical scavenging properties.?The beneficial effect of 7-NI in restoration of the antioxidant cell defense in the brain, impaired by multiple cocaine administration, and along with it the attenuation of the physical dependence, induced by cocaine, once again confirm the role of the oxidative stress in the development of addiction to psychoactive compounds[1]. |
动物实验 | Animals were divided into four groups (n = 12) as follows:group 1: control animals, treated with saline for 7 days, which were involved in the experiment from the very beginning and housed under the same standard laboratory conditions as the treated animals;group 2: animals, receiving 15 mg/kg?1 i.p. of cocaine for 7 days;group 3: animals, receiving 25 mg/kg?1 i.p. 7-NI for 7 days ;group 4: animals, treated with 7-NI (25 mg/kg?1 i.p.) and 30 min later with cocaine (15 mg/kg?1) for 7 days.Twenty-four hours after the last administration of the compounds the animals were observed for behavioral changes related to the withdrawal syndrome.?Then the animals were sacrificed through decapitation and brains were extracted.?Brains of six animals from each group were taken for isolation of synaptosomes and brains from the other six animals of each group were used for measurement of nNOS and antioxidant enzymes[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。
