产品描述：基本信息 产品编号： S10953  产品名称： S-8510 phosphate CAS: 151466-23-8   储存条件 粉末 -20℃ 四年 分子式： C12H13N4O6P 溶于液体 -80℃ 二年 分子量： 340.23     化学名：  Imidazo(4,5-d)pyrano(4,3-b)pyridine,1,6,7,9-tetrahydro-2-(3-isoxazolyl)-,phosphate (1:1) Solubility (25°C)：   体外:   DMSO   Ethanol   Water   体内(现配现用):   ＜1mg/ml表示微溶或不溶。 普西唐提供的所有化合物浓度为内部测试所得，实际溶液度可能与公布值有所偏差，属于正常的批间细微差异现象。 请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液；⼀旦配成溶液，请分装保存，避免反复冻融造成的产品失效。   生物活性 产品描述 一种苯二氮(BDZ)受体的逆向激动剂 靶点 Ki:34.6nM (-GABA),36.2nM (+GABA).   体外研究 S-8510 has a relatively high affinity to BDZ receptors.The ratio of Ki values for each ligand with and without GABA is defined as the GABA ratio,which is considered as a biochemical index for BDZ receptor ligands.The GABA ratio for S-8510 or CGS8216 is close to the value for flumazenil which is considered as an antagonist or a very weak agonist.S-8510 (10-7 M) enhances LTP and this enhancement is antagonized by BDZ receptor antagonist,flumazenil.Flumazenil itself does not atfect LTP or evokes responses prior to tetanic stimulation.S-8510 has no effect on the field evoked potential up to 10-5 M.However,S-8510 increases the amplitude of the population spike at a dose of 10-4 M,and this effect is completely antagonized by concomitant application of flumazenil (10-4 M). 体内研究 S-8510 or CGS8216 could cause lethal convulsion only in combination with more than 90mg/kg of PTZ.The proconvulsant activity of S-8510 appears to be selective for PTZ-induced subconvulsive state.Scopolamine decreases the time spending in the area around the platform,indicating the amnesic action of scopolamine.S-8510 and CGS8216 reverses this scopolamineinduced amnesia.S-8510 improves the memory impairment induced by diazepam in the water maze and passive avoidance paradigms as well.S-8510 dose-dependently increases the ACh level up to 100mg/kg.Both S-8510 and PTZ increases the extracellular level of NA in the hippocampus in a dose-dependent manner.Anxiogenic actions of S-8510,CGS8216 and FG7142 are examined in the water lick conflict paradigm of Wistar rats.S-8510 and CGS8216 fail to affect this behavioral paradigm up to 30mg/kg.S-8510 significantly decreases the immobility time in the forced swimming test using ddY mice at 40 to 80mg/kg in a dose-dependent manner.In the tetrabenazine-induced ptosis model,S-8510 significantly reduces the extent of ptosis induced by tetrabenazine at doses more than 10mg/kg.Again,S-8510 reduces the extent of ptosis only by 39% even at the maximum dose,whereas imipramine exerts more pronounced effects (by about 80% at a dose of 20mg/kg).   推荐实验方法(仅供参考) 动物实验:   Mice,Rats Proconvulsant actions of S-8510 are examined in combiition with a subconvulsive dose of convulsant (PTZ or strychnine) or minimal electroconvulsive shock in ddY mice.Each convulsant is administrated,simultaneously with the inverse agonist,whereas minimal electroconvulsive shock is applied 5 min after intravenous injection of the inverse agonist.The proconvulsant test of S-8510 on PTZ (52,62.5,75 or 90mg/kg s.c.) or strychnine (0.25mg/kg,s.c.)-induced convulsion is made.ED50 values for producing clonic convulsion to death in 50% of ddY mice are calculated.Anxiogenic actions of each inverse agonist are examined in the punished water licking method in Wistar rats.Each inverse agonist is administered per OS 30 min before the test trial.Antiamnesic actions of inverse agonists are examined in the water maze paradigm.Wistar rats are given 4 trials every day for consecutive 4 days.On the 5th day,each animal has the retention test for 60s.Amnesia is produced by intraperitoneally injected scopolamine at a dose of 0.5mg/kg.Scopolamine and each inverse agonist are given 15 min and 30 min before the retention trial,respectively.
