Biological Activity

S/GSK1349572 (GSK1349572, Dolutegravir) is a novel potent inhibitor of HIV integrase  with an IC50 of 2.7 nM in vitro. Dolutegravir (DTG, GSK1349572) is metabolized primarily by uridine diphosphate glucuronyltransferase (UGT)1A1, with a minor role of cytochrome P450 (CYP)3A, and with renal elimination of unchanged compound being extremely low (< 1% of the dose). S/GSK1349572 is a next generation integrase inhibitor (INI) with low nM potency. Susceptibility to S/GSK1349572 and raltegravir (RAL) was determined for INI resistant clinical isolates from therapy experienced patients treated with RAL plus optimized background regimen.

Cell Experiment
Cell lines MT-4 cells
Preparation method Antiviral assay in MT-4 cells. MT-4 cells growing exponentially at a density of 5 × 105 or 6 × 105/ml were infected with HIV-1 strain IIIB at a viral multiplicity of infection of 0.001 or a 50% tissue culture infective dose of 4 to 10. The cells were then aliquoted to 96-well plates in the presence of varying concentrations of compounds. After incubation for 4 or 5 days, antiviral activity was determined by a cell viability assay that either measured bioluminescence with a CellTiter-Glo luminescent reagent (Promega Corporation, Madison, WI) or measured absorbance at 560 and 690 nm using the yellow tetrazolium MTT reagent [3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyltetrazolium bromide].
Concentrations 0.16, 0.8, 4, 20nM
Incubation time 4 or 5 days

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.
