An inhibitor of HIV-1 integrase
Elvitegravir (also known as GS-9137 or JTK-303), a monoketo acid modified from the distinct diketo acid moiety (DKA) motif, is a potent inhibitor of human immunodeficiency virus type I (HIV-1) integrase, an enzyme integrating the viral DNA into the cellular DNA of the host during HIV replication. Elvitegravir inhibits the function of HIV-1 integrase through blocking viral DNA strand transfer and integration, which prevents the replication of HIV and subsequently allows viral DNA to be metabolized by cellular enzymes. Multiple studies indicate that elvitegravir not only inhibits the replication of a variety of subtypes of HIV-1 but also exhibits antiviral activity against murine leukemia virus (MLV) and simian immunodeficirncy virus (SIV).

Cell experiment: | MT-2 cells (2×105 cells) are infected with HIV-1 IIIB and then cultured in the presence of 0.5 nM or 0.1 nM Elvitegravir. Cultures are incubated at 37°C until an extensive cytopathic effect (CPE) is observed, and the culture supernatant is then harvested for further passage in fresh MT-2 cells. The concentration of Elvitegravir is increased when a significant CPE is observed. At the indicated passages, proviral DNA is extracted from infected MT-2 cells and then subjected to PCR, followed by direct population-based sequencing. Susceptibility to Elvitegravir at the indicated passages is determined using the MAGI assay or p24 production[1]. |
