| 产品描述: | 基本信息 产品编号: S10937 产品名称: (S)-(-)-Bay-K-8644 CAS: 98625-26-4 储存条件 粉末 -20℃ 四年 分子式: C16H15F3N2O4 溶于液体 -80℃ 6个月 分子量: 356.30 -20℃ 1个月 化学名: 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。 制备储备液 浓度 溶液体积 质量 1mg 5mg 10mg 1mM 2.8066mL 14.0331mL 28.0662mL 5mM 0.5613mL 2.8066mL 5.6132mL 10mM 0.2807mL 1.4033mL 2.8066mL 生物活性 产品描述 一种L型钙离子通道激动剂。 靶点 EC50:32nM (IBa) 体外研究 (±)-Bay K 8644,a conventional racemic mixture of Bay K 8644,is widely used as an L-type Ca2+ channel agonist. Each optical isomer possesses opposite effects on IBa (R(+)-Bay K 8644 as an antagonist and (S)-(-)-Bay-K-8644 as an agonist.(S)-(-)-BayK-8644 can prevent the inhibitory actions of two distinct cyclic nucleotide pathways on IBa in gastric myocytes of the guinea pig antrum.The Ca2+ channel activity is enhanced by 3–30μM (S)-(-)-Bay-K-8644 an agonist of L-type Ca2+ channels.The interactions of two Ca2+ channel activators (S)-(-)-Bay-K-8644 and FPL 64176 is examined on smooth muscle L-type Ca2+ channels.FPL 64176 (300nM) causes a sustained contraction of rat tail artery strips.This contractile response is inhibited by approximately 70% by (S)-(-)-Bay-K-8644 (EC50=14nM).(S)-(-)-Bay-K-8644 (100nM) increases whole-cell Ca2+ currents in A7r5 smooth muscle cells but effectively blocks further stimulation by 1μM FPL 64176. |
