产品描述 | SR 57227A (SR 57227 hydrochloride) is a potent, orally active and selective 5-HT3 receptor agonist. It with ability to cross the blood brain barrier. It has affinities (IC50) varying between 2.8 and 250 nM for 5-HT3 receptor binding sites in rat cortical membranes and on whole NG 108-15 cells or their membranes. Anti-depressant effects. |
体内活性 | Seizure latency was significantly prolonged by a 5-HT3 receptor agonist SR 57227 in a dose-dependent manner.?Seizure score and mortality were also decreased by SR 57227 in PTZ-treated mice.?Furthermore, these anticonvulsant effects of SR 57227 were inhibited by a 5-HT3 receptor antagonist ondansetron.?However, ondansetron alone had no effect on seizure latency, seizure score or mortality at different doses.?Immunohistochemical studies have also shown that c-Fos expression was significantly increased in hippocampus (dentate gyrus, CA1, CA3 and CA4) of PTZ-treated mice.?Furthermore, c-Fos expression was significantly inhibited by ondansetron in mice treated with PTZ and SR 57227.?An ELISA study showed that SR 57227 attenuated the PTZ-induced inhibitory effects of GABA levels in hippocampus and cortex, and the attenuated effects of SR 57227 were antagonized by ondansetron in hippocampus but not cortex.?Activation of 5-HT3 receptor by SR 57227, which plays an important role on the control of seizure induced by PTZ, may be related to GABA activity in hippocampus.?Therefore, 5-HT3 receptor subtype is a potential target for the treatment of epilepsy[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。
