Product Description

Biological Activity

Description Elvitegravir (GS-9137, JTK-303) is an HIV integrase inhibitor for HIV-1 IIIB, HIV-2 EHO and HIV-2 ROD with IC50 of 0.7 nM, 2.8 nM and 1.4 nM in cell-free assays, respectively.
Targets HIV-1 IIIB [1]
(Cell-free assay)
HIV-2 ROD [1]
(Cell-free assay)
HIV-2 EHO [1]
(Cell-free assay)
IC50 0.7 nM 1.4 nM 2.8 nM
In vitro Elvitegravir inhibits PBMC and PA with IC50 of 0.89 and 20 nM, respectively. Elvitegravir prevents the integration of HIV-1 cDNA through the inhibition of DNA strand transfer. Elvitegravir suppresses the replication of HIV-1, including various subtypes and multiple-drug-resistant clinical isolates, and HIV-2 strains with a 50% effective concentration in the subnanomolar to nanomolar range. Elvitegravir inhibits the replication of HIV-1 clinical isolates carrying NRTI, NNRTI, and PI resistance-associated genotypes. Elvitegravir inhibits the HIV replication at a step that occurs after reverse transcription but before proteolytic cleavage, consistent with the integration step. Elvitegravir inhibits the synthesis of strand transfer products with an IC50 of 54 nM. Elvitegravir blocks integration via the inhibition of IN-mediated strand transfer. [1] Elvitegravir inhibits the integration of the HIV-based vector used as a positive control for the luciferase assay with an EC50 of 0.8 nM, as observed in the MAGI assay with HIV-1IIIB. Elvitegravir suppresses the replication of MLV infection with IC50 of 5.8 nM as well as that of the primate retrovirus SIV (IC50 = 0.5 nM), revealing that IN inhibitors have antiviral activity against a broad range of retroviruses. EVG is active against HIV-1 and HIV-2 and has a serum-free antiviral IC50 of 0.3-0.9 nM in peripheral blood mononuclear cells. [2]

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.

Results For compounds(Elvitegravir, Rifampicin, Rifampicin and Maraviroc) with significant induction of ABCB1 mRNA expression at 10 mmol/L, induction was also quantified at the functional level after 3 days and 1 week of incubation. After 3 days of treatment, a trend towards increased ABCB1 activity was observed for Rifampicin and Elvitegravir. After 7 days ABCB1 activity was significantly increased by Elvitegravir, Vicriviroc and the positive control, Rifampicin.

Incubation Time 0-25 h
Results The addition of AZT could be delayed for about 4.8 h before 50% loss in potency was observed, whereas NVP required about 7.2 h to reveal this effect(Fig. 1A). These data reflect the need for AZT conversion to its active phosphorylated form, which NVP does not require. RAL addition could be postponed for about 10.2 h before 50% loss in activity was observed, whereas EVG required about 11.1 h. Titrating RAL and EVG over a 10-fold range (from 10× to 100× the EC95 ) did not significantly affect the resulting time windows (10.1 to 12.7 h for 50% inhibition) (Fig. B).
