| In Vitro | GS-443902 (compound 8a), a triphosphates (TP) derivative, is a potent inhibitory activity against the enzyme TP RdRp (IC50=5.6 µM). In a continuous 72 h incubation of 1 µM GS-5734, the GS-443902 (compound 4tp) 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 (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. |
| In Vivo | GS-5734 (10 mg kg; i.v.) rapidly distributes into peripheral blood mononuclear cells (PBMCs), and efficient conversion to GS-443902 (NTP) is apparent within 2 h of dose administration in rhesus monkeys. In PBMCs, GS-443902 represents the predominant metabolite and is persistent with a t1/2 of 14 h and levels required for >50% virus inhibition for 24 hours. |
| Target | DNA/RNA Synthesis; SARS-CoV; RSV; HCV; Drug Metabolite |

Description of First Aid Measures
Eye contact
Remove any contact lenses, locate eye-wash station, and flush eyes immediately with large amounts of water. Separate eyelids with fingers to ensure adequate flushing. Promptly call a physician.
Skin contactRinse skin thoroughly with large amounts of water. Remove contaminated clothing and shoes and call a physician.
InhalationImmediately relocate self or casualty to fresh air. If breathing is difficult, give cardiopulmonary resuscitation (CPR). Avoid mouth-to-mouth resuscitation.
IngestionWash out mouth with water; Do NOT induce vomiting; call a physician.
