HIV integrase

Dolutegravir(S/GSK1349572) inhibits HIV-1 integrase-catalyzed strand transfer with a 50% inhibitory concentration (IC50) of 2.7 nM. S/GSK1349572 inhibits both the HIV integration reaction strand transfer step in vitro and HIV replication in cells with similar potencies. The inhibitor has no effect on total viral DNA synthesis in infected cells but blocks the integration of viral DNA into host DNA with the same potency as its antiviral effect.

The bioavailability of dolutegravir was high when administered as a solution, but was limited by dissolution rate or solubility when administered as a suspension. Dolutegravir is the major circulating component in mice, rats, and monkeys, with direct ether glucuronidation shown to be the primary biotransformation pathway. Dolutegravir is primarily eliminated via the feces either unabsorbed or by hydrolysis of the glucuronide or glucose conjugate.
