Abstract
Human immunodeficiency virus type 1 reverse transcriptase (HIV-1 RT) is an important target for antiviral therapy against acquired immunodeficiency syndrome. However, the efficiency of available drugs is impaired most typically by drug-resistance mutations in this enzyme. In this study, we applied a nuclear magnetic resonance (NMR) spectroscopic technique to the characterization of the binding of HIV-1 RT to various non-nucleoside reverse transcriptase inhibitors (NNRTIs) with different activities, i.e., nevirapine, delavirdine, efavirenz, dapivirine, etravirine, and rilpivirine. 1H-13C heteronuclear single-quantum coherence (HSQC) spectral data of HIV-1 RT, in which the methionine methyl groups of the p66 subunit were selectively labeled with 13C, were collected in the presence and absence of these NNRTIs. We found that the methyl 13C chemical shifts of the M230 resonance of HIV-1 RT bound to these drugs exhibited a high correlation with their anti-HIV-1 RT activities. This methionine residue is located in proximity to the NNRTI-binding pocket but not directly involved in drug interactions and serves as a conformational probe, indicating that the open conformation of HIV-1 RT was more populated with NNRTIs with higher inhibitory activities. Thus, the NMR approach offers a useful tool to screen for novel NNRTIs in developing anti-HIV drugs.

Abstract
A common problem with non-nucleoside reverse transcriptase inhibitors (NNRTIs) of HIV-1 is the emergence of mutations in the HIV-1 RT, in particular Lys103 → Asn (K103N) and Tyr181 → Cys (Y181C), which lead to resistance to this entire class of inhibitors. In this study, we theoretically designed two new non-nucleoside HIV-1 RT inhibitors, Mnev-1 and Mnev-2, derived from nevirapine, in order to reduce the resistance caused by those HIV-1 RT mutations. The binding modes of Mnev-1 and Mnev-2 with the wild-type HIV-1 RT and its mutants (K103N and Y181C) were suggested by molecular docking followed by 20-ns molecular dynamics (MD) simulations in explicit water of those binding complexes (HIV-1 RTs with the new inhibitors). A molecular mechanics/generalized Born surface area (MM/GBSA) calculation was carried out for multiple snapshots extracted from the MD trajectory to estimate the binding free energy. The results of the calculations show that each of the new inhibitors forms a stable hydrogen bond with His235 during the MD simulations, leading to tighter binding of the new inhibitors with their targets. In addition, the repulsive interaction with Cys181 in the Y181C-nevirapine complex is not present in the novel inhibitors. The binding affinities predicted using the MM/GBSA calculations indicate that the new inhibitors could be effective at bypassing the drug resistance of these HIV-1 RT mutants.

Abstract
EFdA (4'-ethynyl-2-fluoro-2'-deoxyadenosine), a nucleoside reverse transcriptase inhibitor with extremely potent anti-HIV activity, was concisely synthesized from (R)-glyceraldehyde acetonide in an 18% overall yield by a 12-step sequence involving highly diastereoselective ethynylation of an α-alkoxy ketone intermediate. The present synthesis is superior, both in overall yield and in the number of steps, to the previous one which required 18 steps from an expensive starting material and resulted in a modest overall yield of 2.5%.
