Non-nucleoside reverse transcriptase ...The use of highly active antiretroviral therapy (HAART) has made the human immunodeficiency virus (HIV) a chronic disease rather than a terminal disease. Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are an important component of HAART, although we are seeing clinically relevant drug-resistant mutants such that there is a need to develop new molecules. We recently identified a new class of -phenyl-1-(phenylsulfonyl)-1-1,2,4-triazol-3-amine HIV-1 NNRTI, with one known as compound 12126065, with sub nanomolar (nM) potency in TZM-bl cells (HeLa cells expressing CD4, CCR5, and CXCR4) with no in vivo acute or subacute toxicity. We now describe the cryo-EM structure of this molecule (resolution of 3.53 Å) and compare it to analogues and other known NNRTIs. We also describe the synthesis and activity of five additional analogues of this class of compounds, some of which have promising activity against a K103N/Y181C (A17) double mutant, which will enable the design of future molecules. | ||||||

The grids were glow-discharged for 25 s at 25 mA with the chamber pressure set at 0.3 mbar (PELCO easiGlow; Ted Pella). The grids were prepared using the Leica GP2 plunge freezer with its chamber set to 10oC and 95% humidity. Samples of purified HIV-1 RT were diluted to 1mg/mL and 2 molar equivalents of the appropriate compound 12126065 were incubated on a 4oC rotator overnight to combine. A total of 4uL of HIV-1 RT and compound were applied to the backside of the Quantifoil grid and blotted for 4 seconds on the carbon side before plunge frozen in ethane at -181oC. |
