Problems solved by technology

[0002] Although there are currently two FDA-approved HIV integrase inhibitors (raltegravir and elvitegravir) on the market, both have shown resistance and extensive cross-resistance to Low to moderate genetic barrier to drug resistance, which increases the need for inhibitors with improved potency against raltegravir-resistant strains

Embodiment

[0594] Assay protocol:

[0595] In vitro integrase assay. The integrase reaction was performed by adding drug or an equal volume of 100% dimethyl sulfoxide (DMSO; used as drug solvent) to 20 nM DNA and 400 nM integrase in 50 mM morpholine propane sulfonic acid (pH 7.2), 7.5 mM MgCl 2 and 14 mM 2-mercaptoethanol in a mixture. Reactions were performed at 37°C for 2 hours and quenched by adding an equal volume of loading buffer (formamide containing 1% sodium dodecyl sulfate, 0.25% bromophenol blue, and xylene cyanol). Reaction products were separated on a 16% polyacrylamide denaturing sequencing gel. Dried gels were visualized using a Typhoon 8600 (GE Healthcare, Piscataway, NJ). Densitometric analysis was performed using ImageQuant 5.1 software from GE Healthcare. Data analysis of at least 3 independent measurements was performed using GraphPad's Prism 5.0c software (linear regression, 50% inhibitory concentration [IC 50 ] determination, standard deviation [SD]).
