Mycalolide-B is a marine sponge-derived compound that functions as a selective inhibitor of actomyosin ATPase. It effectively hinders ATP-induced contraction and Mg2+-ATPase activity in the absence of Ca2+.
产品描述 | Mycalolide-B is a marine sponge-derived compound that functions as a selective inhibitor of actomyosin ATPase. It effectively hinders ATP-induced contraction and Mg2+-ATPase activity in the absence of Ca2+. |
体外活性 | Mycalolide-B belongs to macrolide antibiotics and consists of tris-oxazole with strong cytotoxic activity (IC 50 : 10-50 nM for growth of L1210 murine leukemia cells). Mycalolide-B, a toxin isolated from marine sponge, inhibits smooth muscle contractions without changing cytosolic Ca 2+ levels. Mycalolide-B also inhibits Ca 2+ -induced contraction in permeabilized smooth muscles. Mycalolide-B inhibits superprecipitation and Mg 2+ -ATPase activity stimulated by Ca 2+ without changing myosin light chain phosphorylation. Mycalolide-B inhibits ATP-induced contraction and Mg 2+ -ATPase activity in the absence of Ca 2+[1]. |

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。
