产品描述 | Ceralifimod (ONO-4641) is a potent agonist for sphingosine 1-phosphate receptors 1 and 5 (EC50s: 27.3, 334 pM for human S1P receptor 1 and 5). |
靶点活性 | S1P1 (human):(EC50)27.3 pM, S1P5 (human):334 pM(EC50) |
体外活性 | Ceralifimod induces S1P1 down-regulation in a concentration-dependent manner and by approximately 90% at a concentration of 25 nM. Ceralifimod has an agonistic action for S1P1 and S1P5. However, there is no difference between humans and rats in the agonistic action of Ceralifimod for S1P1. |
体内活性 | The maximum clinical scores decrease dose-dependently in the Ceralifimod groups and those in the Ceralifimod 0.03 and 0.1 mg/kg groups are significantly lower than that in the control group. In the Ceralifimod 0.1 mg/kg group, paralysis is inhibited completely in seven of eight animals. In contrast, none of the animals in the Ceralifimod 0.1 mg/kg group have a relapse; that is, Ceralifimod completely prevents relapse at a dose of 0.1 mg/kg. In normal NOD mice, the number of peripheral blood lymphocytes is decreased by approximately 20, 60, and 80% at 24 h after a single oral dose of 0.01, 0.03, and 0.1 mg/kg of Ceralifimod, respectively. In the control group of the NOD mouse model of relapsing-remitting EAE, the relapse rate is 90.0%, and two of the nine animals die. In the Ceralifimod groups, two of the nine animals in the 0.01 mg/kg died. |

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。
