| 产品描述: | 基本信息 产品编号: L50021 产品名称: Lintitript CAS: 136381-85-6 储存条件 粉末 -20℃ 四年 分子式: C20H14ClN3O3S 溶于液体 -80℃ 6个月 分子量: 411.86 -20℃ 1个月 化学名: 2-[2-[[4-(2-chlorophenyl)-1,3-thiazol-2-yl]carbamoyl]indol-1-yl]acetic acid Solubility (25°C): 体外: DMSO Ethanol 'mg/mL 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,选择性,口服活性,竞争性和非肽类 CCK1 受体拮抗剂,EC50 为 6nM,Ki 为 0.2nM。Lintitript 对 CCK1 的选择性比对 CCK2 受体的选择性高 33 倍以上 (EC50值为 200nM)。 靶点 EC50:6nM (cholecystokinin (CCK1) receptor);Ki:0.2nM (cholecystokinin (CCK1) receptor) 体外研究 In vitro,Lintitript (SR 27897) is a competitive antagonist of cholecystokinin (CCK)-stimulated amylase release in isolated rat pancreatic acini (pA2=7.50) and of CCK-induced guinea pig gall bladder contractions (pA2=9.57).Lintitript produces concentration dependent inhibition of [125I]CCK binding to CCK1 receptor sites in the rat pancreas (IC50 value of 0.58nM) and also to CCK 2 sites in the guinea pig cortex (IC2 value of 479nM).Lintitript inhibits [125I]gastrin binding to gastrin receptors. Lintitript (0.5nM) increases the dissociation constant of CCK for the CCK A receptor (Kd=1.8 to 7.2nM) without modifying the maximum number of receptors (Bmax=1800 to 1770 fmol/mg). 体内研究 Lintitript (SR 27897;1mg/kg,i.v.) completely reverses the CCK-induced amylase secretion.Lintitript also inhibits CCKinduced gastric and gallbladder emptying in mice (ED50s=3 and 72μg/kg,respectively).Lintitript is also very active (ED50=27μg/kg p.o.) in the gall bladder emptying protocol with egg yolk as an inducer of endogenous CCK release. |
