Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	Reverse transcriptase ^[1]
In vitro	GS-7340 has a potent anti-HIV activity with IC50 of 0.005 μM. ^[1] GS 7340 has a half-life of 90 min in human plasma and a half-life of 28.3 min in an MT-2 cell extract at 37°C. ^[2] the hepatic uptake of GS-7340 isfacilitated by OATP1B1 and OATP1B3, respectively. GS-7340 inhibits HBV reverse transcriptase after being converted to the pharmacologically active form, TFV-DP. ^[3]
In vivo	In male beagle dogs, GS 7340 (10 mg/kg, p.o.) results in an enhanced distribution to lymphatic tissue. ^[2]
