产品描述 | GS-443902 trisodium (GS-441524 triphosphate trisodium), the active triphosphate metabolite of Remdesivir (GS-5734), serves as a potent inhibitor of viral RNA-dependent RNA-polymerases (RdRp), displaying inhibitory concentrations (IC50) of 1.1 μM and 5 μM for RSV RdRp and HCV RdRp, respectively. |
靶点活性 | HCV RdRp:5 µM (IC50), RdRp (RSV):1.1 µM (IC50) |
体外活性 | In a continuous 72 h incubation of 1 μM Remdesivir (GS-5734), the GS-443902 trisodium (GS-441524 triphosphate trisodium; Remdesivir metabolite trisodium) level is measured at 2, 24, 48 and 72 h, and reaches a C max of 300, 110, and 90 pmol/million cells in macrophages, HMVEC, and HeLa cells lines respectively[1]. GS-443902 trisodium (compound 8a) is a triphosphates (TP) derivative[2]. GS-443902 trisodium (NTP; 0.01, 0.1, 1, 10, 100 μM) inhibits RSV RdRp-catalysed RNA synthesis by incorporating into the nascent viral RNA transcript and causing its premature termination. GS-5734 selectively inhibits EBOV replication by targeting its RdRp and inhibiting viral RNA synthesis following efficient intracellular conversion to GS-443902 sodium[3]. |
体内活性 | Remdesivir (GS-5734; 10?mg?kg; i.v.) rapidly distributes into peripheral blood mononuclear cells (PBMCs), and efficient conversion to GS-443902 trisodium (Remdesivir metabolite trisodium; NTP) is apparent within 2?h of dose administration in rhesus monkeys. In PBMCs, GS-443902 trisodium represents the predominant metabolite and is persistent with a t 1/2 of 14?h and levels required for >50% virus inhibition for 24?hours[3]. |

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。
