體外研究活性 | PF543是一種細胞滲透性羥基甲基吡咯烷化合物,其以可逆的,鞘氨醇競爭性方式抑制SphK-1/SphK1催化的鞘氨醇磷酸化,對S1P受體沒有親和力,對Sphk2 (10 μM下抑制6.8%)或 46種其他脂質和蛋白激酶(IC50 >10 μM)的抑制活性很弱。在SphK1過表達的1483頭頸癌細胞中,PF-543減少10倍的內源性S1P水平,并成比例增加鞘氨醇水平。PF-543與SphK1可逆結合(k off t1/2=8.5 min),具有高親和力,結合常數(shù)(Kd)為5 nM。PF543不影響1483,A549,LN229,Jurkat,U937和MCF-7細胞的增殖和存活,盡管會使細胞中S1P/鞘氨醇比率發(fā)生巨大改變。在全血中,PF-543是有效的S1P形成抑制劑,表明鞘氨醇激酶的SphK1亞型是人血中S1P的主要來源。[1] |

動物體內配方計算器(澄清溶液)
第一步:請輸入基本實驗信息(考慮到實驗過程中的損耗,建議多配一只動物的藥量)
第二步:請輸入動物體內配方組成(配方適用于不溶于水的藥物;不同批次藥物配方比例不同,請聯(lián)系Selleck為您提供正確的澄清溶液配方)
計算結果:
工作液濃度: mg/ml;
DMSO母液配制方法: mg 藥物溶于μL DMSO溶液(母液濃度mg/mL,注:如該濃度超過該批次藥物DMSO溶解度,請先聯(lián)系Selleck);
體內配方配制方法:取μL DMSO母液,加入μL PEG300,混勻澄清后加入μL Tween 80,混勻澄清后加入μL ddH2O,混勻澄清。
體內配方配制方法:取μL DMSO母液,加入μL Corn oil,混勻澄清。
注意:1. 首先保證母液是澄清的;
2.一定要按照順序依次將溶劑加入,進行下一步操作之前必須保證上一步操作得到的是澄清的溶液,可采用渦旋、超聲或水浴加熱等物理方法助溶。
