产品描述:基本信息 产品编号: T11460 产品名称: Timepidium bromide CAS: 35035-05-3   储存条件 粉末 -20℃ 四年 分子式: C17H22BrNOs2 溶于液体 -80℃ 二年 分子量 400.40     化学名:  3-(dithiophen-2-ylmethylidene)-5-methoxy-1,1-dimethylpiperidin-1-ium;bromide 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 一种抗胆碱剂。 靶点 Cholinergic    体内研究 Effects of Timepidium bromide (TB),acetylcholine (ACh) and neostigmine (Neost) on gastric and duodenal blood flow distribution are studied by the use of 131I-labeled macroaggregated human serum albumin (MAA) in rabbits. In normal rabbits,gastric blood flow is found to be uneven in various regions of the stomach:anterior corpus (50% of total gastric blood flow) greater than posterior corpus (40%) greater than pyloric antrum (7%).Intravenous administration of Timepidium bromide (200μg/kg) to normal rabbits produces a slight increase in total gastric blood flow,but the increase in the mucosal layer of the pyloric antrum is considerable.   推荐实验方法(仅供参考) 动物实验:   Rabbits Timepidium bromide (200μg/kg) is injected into the femoral vein 5 min prior to 131I-MAA.To evaluate the effects of Timepidium bromide on gastric and duodenal blood flow in cholinergic drug-treated animals, Timepidium bromide is administered in a dose of 200μg/kg through the femoral vein 3 min before ACh or 5 min after Neost.131I-MAA is given into the left ventricle of the animals 2 min after ACh and 10 min after Neost.
