Background

GSK744 (S/GSK1265744) is a potential inhibitor of HIV integrase with IC50 value of 3 nM [1].
HIV integrase is an enzyme produced by HIV virus that enables its genetic material to be integrated into the infected cell DNA. It is reported that HIV intergrase inhibitor plays an important role in halting HIV progression [2].
GSK744 (S/GSK1265744) is a potent HIV integrase inhibitor. Using resistance passage experiments, integrase enzyme assays, and cellular assays with site-directed molecular (SDM) HIV clones resistant to other classes of anti-HIV-1 agents and earlier integrase strand transfer inhibitors, results showed that GSK1265744 efficiently inhibited HIV replication through inhibiting HIV integrase [1].
In female pigtail macaques model that intravaginal inoculated simian/human immunodeficiency virus twice a week for up to 11 weeks, GSK744 injection prevented the macaques from being infected by virus while placebo controls were infected after a 4 median vaginal challenges with SHIV which reminded that GSK744 may be a potential preexposure prophylaxis drug for prevention via inhibiting HIV integrase [3] [2].
Many clinical trials have been conducted to show that GSK744 can efficiently protected healthy subjects from HIV infection [4-6].
