产品描述 | CI-949 is an allergic mediator release inhibitor, which inhibits leukotriene C4/D4 (LTC4/LTD4), histamine, and thromboxane B2 (TXB2) release (IC50s: 0.5 μM, 11.4 μM and 0.1 μM). |
靶点活性 | Histamine:, LTD4:0.5 μM, LTC4:0.5 μM, TXB2:0.1 μM |
体外活性 | Complete inhibition of leukotriene and thromboxane synthesis/release is obtained with 10 and 1 μM of CI-949, respectively. CI-949 is an effective inhibitor of the release of all three mediators in response to this stimulus. The IC50s for inhibition of histamine, leukotriene, and thromboxane are 6.3, 2, and 0.1 μM for the FMLP challenge [1]. CI-949 effectively inhibits the release of histamine and the synthesis or release of immunoreactive sulfidopeptide leukotrienes C4-D4 and thromboxane B2 from antigen-challenged lung fragments of actively sensitized guinea-pigs. The IC50s are 26.7±2.8 μM for histamine, 2.7±2.4 μM for leukotriene, and 3.0±1.8 μM for thromboxane [2]. |
体内活性 | A dose of 50 mg/kg i.p. of CI-949 protects conscious, aerosol-allergen challenged guinea-pigs for at least 1 h and 100 mg/kg i.p. or per os protects for at least 2 h. The animals are protected from collapse for at least I h after 50 and 100 mg/kg, and 100 mg/kg afforded complete protection up to 2h. An oral dose of 100 mg/kg at 2 h, but not at 4 h before challenge also inhibits collapse. A dose of 100 mg/kg at 4 h and again at 2 h before the challenge is more effective than a single dose at 2 h [2]. |

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。
