生物活性

Dolutegravir (S/GSK1349572) is a highly potent and orally bioavailable HIV integrase strand transfer inhibitor with an IC50 of 2.7 nM for HIV-1 integrase-catalyzed strand transfer. Dolutegravir (S/GSK1349572) inhibits HIV-1 viral replication with an IC50 of 0.51 nM in peripheral blood mononuclear cells. Dolutegravir retains a high potency against the HIV-1 Y143R, N155H, and G140S/Q148H mutants (EC50=3.6-5.8 nM).

IC50 & Target[1][2]

IC50: 2.7 nM (HIV-1 integrase-catalyzed strand transfer)

体外研究(In Vitro)

The EC50 of Dolutegravir (S/GSK1349572) against HIV-1 is 0.51 nM in PBMCs, 0.71 nM in MT-4 cells, and 2.2 nM in the PHIV assay, which uses a pseudotyped self-inactivating virus. The 50% cytotoxic concentrations (CC50) for Dolutegravir in proliferating IM-9, U-937, MT-4, and Molt-4 cells are 4.8, 7.0, 14, and 15 μM, respectively. In unstimulated and stimulated PBMCs, the CC50 are 189 μM and 52 μM, respectively. Based on the EC50 of Dolutegravir against HIV-1 in PBMCs (i.e., 0.51 nM), this translates to a cell-based therapeutic index of at least 9,400.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究(In Vivo)

Following a single intravenous (IV) administration of Dolutegravir, the plasma clearance is low in rats (0.23 mL/min/kg) and monkeys (2.12 mL/min/kg). The half-lives in the rat and monkey are similar, approximately 6 h, and the steady-state volume of distribution (VSS) is low. Following oral administration, Dolutegravir is rapidly absorbed with a high oral bioavailability when administered as a solution to fasted male rats and a single monkey (75.6 and 87.0%, respectively). Dolutegravir exposure (Cmax and AUC) increased with increasing dose following oral administration of a suspension to non-fasted rats up to 250 mg/kg and non-fasted monkeys up to 50 mg/kg, although the increase is less than proportional.

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。
