MCE 国际站:GS-443902 trisodium
产品活性:GS-443902 trisodium (GS-441524 triphosphate trisodium) 是一种有效的病毒 RNA 依赖的 RNA 聚合酶 (RdRp) 抑制剂,对 RSV RdRp 和 HCV RdRp 的 IC50 分别为 1.1 µM 和 5 µM。GS-443902 trisodium 是 Remdesivir (GS-5734) 的活性三磷酸盐代谢产物。
研究领域:Cell Cycle/DNA Damage | Anti-infection | Metabolic Enzyme/Protease
作用靶点:DNA/RNA Synthesis | SARS-CoV | RSV | HCV | Drug Metabolite
In Vitro: 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 Cmax of 300, 110, and 90 pmol/million cells in macrophages, HMVEC, and HeLa cells lines respectively.
GS-443902 trisodium (compound 8a) is a triphosphates (TP) derivative.
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.
In Vivo: 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 t1/2 of 14 h and levels required for >50% virus inhibition for 24 hours.
