生物活性

产品描述 Dolutegravir是一种两个金属结合的HIV integrase抑制剂,无细胞试验中IC50为2.7 nM,对耐Raltegravir的显著突变体Y143R,Q148K,N155H,和G140S/Q148H具有适度的活性。

体外研究(In Vitro)
体外研究活性

S/GSK1349572对来自整合酶抑制剂-天然HIV-2感染患者的9种临床分离株表现出有效的抑制作用,EC50范围为0.2 nM -1.4 nM。[1]

在体外,S/GSK1349572抑制重组HIV-1整合酶催化的链转移,IC50为2.7 nM。此外,S/GSK1349572有效抑制细胞中HIV复制,如作用于感染自身灭活的PHIV慢病毒载体的外周血单核细胞(PBMCs),MT-4 细胞和CIP4细胞,EC50分别为0.51 nM,0.71 nM和2.2 nM。[2]

在体外,S/GSK1349572对5种不同的非核苷逆转录抑制剂抗性病毒,或核苷逆转录抑制剂抗性病毒表现出有效的活性,EC50范围为1.3 nM -2.1 nM。与抗野生型病毒类似,S/GSK1349572对两种蛋白酶抑制剂抗性病毒表现出同样的活性,EC50为0.36 nM和0.37 nM。[2]

激酶实验 体外链转移试验
S/GSK1349572和其他INIs的抑制效能通过链转移试验使用重组HIV整合酶测量。整合酶和生物素化预处理的供体DNA-链霉亲和素包被的闪烁迫近测定(SPA)珠复合物,通过将2 μM纯化的重组整合酶与0.66 μM生物素化供体DNA-4 mg/mL链霉亲和素包被的SPA珠在25 mM 吗啡啉丙磺酸钠(MOPS) (pH 7.2),23 mM NaCl,和10 mM MgCl2于37 °C下培养5分钟制备。将这些珠子离心,并与稀释的INIs在37 °C下预培养60分钟。然后加入3H-标记的靶DNA底物,得到底物终浓度为7 nM,将链转移反应混合物在37 °C下培育25到45分钟,使供体DNA到放射性标记的靶DNA链转移线性增加。信号使用Wallac MicroBeta闪烁酶标仪读取。
