产品描述 | ABT-546 (A-216546) is a potent, highly selective, and active endothelin ETA receptor antagonist with a Ki of 0.46 nM for [125I]endothelin-1 binding to cloned human endothelin ETA. |
靶点活性 | ETA:0.46 nM (ki) |
体外活性 | ABT-546 is >25,000-fold more selective for the ETA receptor than for the ETB receptor. ABT-546 blocks endothelin-1-induced arachidonic acid release and phosphatidylinositol hydrolysis (IC50s: 0.59 nM and 3 nM). ABT-546 effectively inhibits specific I endothelin-1 binding to endothelin ETA receptor in membranes prepared from rat pituitary MMQ cells (IC50: 0.56 nM). In membranes prepared from CHO cells stably transfected with the human endothelin ETA and ETB receptors, ABT-546 again effectively inhibits specific [125I]endothelin-1 binding to endothelin ETA receptor (IC50: 0.49 nM), but is less effective in inhibiting specific [125I]endothelin-3 binding to endothelin ETB receptor (IC50: 15,400 nM). In isolated vessels, ABT-546 inhibits endothelin ETA receptor-mediated endothelin-1-induced vasoconstriction, and endothelin ETB receptor-mediated sarafotoxin 6c-induces vasoconstriction with pA2 of 8.29 and 4.57, respectively. |
体内活性 | ABT-546 (0-100 mg/kg; p.o.; for 1 hour or 4 hours; male Sprague-Dawley rats) treatment dose-dependently blocks the endothelin-1-induced pressor response in conscious rats. |
动物实验 | Animal Model: Male Sprague-Dawley rats (250-350 g) induced with endothelin-1. Dosage: 0.1 mg/kg, 1 mg/kg, 10 mg/kg, 30 mg/kg, 100 mg/kg. Administration: p.o.; for 1 hour or 4 hours |

对于不同动物的给药剂量换算,您也可以参考 更多...
请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
