Biological Activity
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[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].
