L-741626 是D2多巴胺受体选择性拮抗剂,对人 D2、D3 和 D4 受体的Ki 分别为 2.4、100 和 220 nM。
产品描述 | L-741626 is a selective antagonist of D2 dopamine receptor (Ki: 2.4, 100, and 220 nM for human D2, D3 and D4 receptors respectively). |
靶点活性 | human D2 receptor:(ki)2.4 nM, human D3 receptor:100 nM(ki), human D4 receptor:220 nM(ki) |
体外活性 | L-741626 is an effective antagonist (EC50 (D2)=4.46 nM) with some D2 selectivity (EC50 (D3)=90.4 nM), in the functional assay. L-741626 is prepared by literature methods (Ki (D2)=11.2 nM). L-741626 also shows a D3/D2 and D4/D2 selectivity ratio of 15-fold and 136-fold, respectively. Intrinsic activities using inhibition of quinpirole stimulation of mitogenesis in human dopamine D2 or D3 receptors transfected into Chinese hamster ovary (CHO) cells, in a functional assay [2]. |
体内活性 | In pramipexole-trained male Sprague Dawley rats, L-741626 (1.0 mg/kg; i.h.) is effective at shifting to the right the pramipexole dose-response curve [3]. Coadministration Cocaine with the D2 antagonist L-741626 (3 mg/kg; i.p.; 15 min before Cocaine) for 5 days decreases the Cocaine-induced enhance in microglial TNF-α production in adult mice [4]. |

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。
