PhA efflux in MDCKII-BCRP cells. Concentration-dependent inhibition of BCRP/ABCG2 by elvitegravir and vicriviroc. Each curve depicts one representative experiment of a series of three or four; each concentration was tested in 30000 cells.

 

Strand transfer was carried out with RSV IN(1-269) (4 uM) and GU320R(2 uM)in the presence of 50mM NDSB201. Increasing concentrations of STIs were added as indicated at the top; DTG(Dolutegravir) in lanes 3-5, MK-2048 in lanes 6-8, and RAL in lanes 9-11. No STI was present in lane 2, and lane 1 contains the molecular weight markers. Strand transfer products and ODN substrate are identified on the right. CHS, circular half-site; OC target and SC target, open circular and supercoiled target DNA, respectively.

Comparison of the activity of dolutegravir (DTG), raltegravir (RAL), and elvitegravir (EVG) against wild-type HIV-2ROD9. Values for RAL and EVG include data from two previously-published studies of HIV-2 from our group [14,15] plus additional determinations; all data were obtained using the single-cycle assay. Bars indicate mean 50% effective concentrations (EC50); the number of independent determinations (n) for each strain is shown below the x-axis. P values were obtained via analysis of variance (ANOVA) of log10-transformed EC50 values with Tukey’s post test (Prism v6.0). No cytotoxic effects were observed in dolutegravir-treated MAGIC-5A cultures at concentrations as high as 10,000 nM.
