Description

GS-443902 trisodium (GS-441524 triphosphate trisodium) is a potent viral RNA-dependent RNA-polymerases (RdRp) inhibitor with IC50s of 1.1 μM, 5 μM for RSV RdRp and HCV RdRp, respectively. GS-443902 trisodium is the active triphosphate metabolite of Remdesivir (GS-5734)[1][2].

IC50 & Target

IC50: 1.1 μM (RSV RdRp) and 5 μM (HCV RdRp)[1][2]
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[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].

* Please refer to the solubility information to select the appropriate solvent. The compound is unstable in solutions, freshly prepared is recommended.

* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
