产品描述:基本信息 产品编号: M11615  产品名称: MLS1547 CAS: 315698-36-3   储存条件 粉末 -20℃ 四年 分子式: C19H19ClN4O 溶于液体 -80℃ 二年 分子量: 354.83     化学名:  5-chloro-7-{[4-(2-pyridinyl)-1-piperazinyl]methyl}-8-quinolinol 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 一种高效的 G 蛋白偏向多巴胺 D2 受体 (D2R) 激动剂。 靶点 H3 Receptor 50.3nM (Kd)   体外研究 (R)-(-)-α-Methylhistamine dihydrobromide is an H3-agonist that is>10 times as potent as histamine (HA).Its selectivity toward H3-receptors is>1,000 times as high as that of HA.(R)-(-)-α-Methylhistamine dihydrobromide has only weak affinities for H1 and H2 receptor with a pKi=4.8 and<3.5,repectively.(R)-(-)-α-Methylhistamine dihydrobromide displays >200-fold selectivity over H4 receptors. 体内研究 Pretreatment with (R)-(-)-α-Methylhistamine dihydrobromide (RAMH;10mg/kg;i.p.;60 min before training) reverses propofol‐induced (25mg/kg;i.p.;30 min before training) memory retention.(R)-alpha-Methylhistamine dihydrochloride (6.3mg/kg;i.p.) significantly decreases the steady-state t-MH level in the mouse brain,whereas these compounds produced no significant changes in the HA level. Animal Model: Male Sprague‐Dawley rats (10-12 week) Dosage: 10mg/kg Administration: IP;60 min before training Result: Reversed propofol‐induced memory retention.
