Abstract
In this study, a novel series of diarylpyrimidine derivatives with Fsp3-enriched spirocycles were designed and synthesized to further explore the chemical space of the hydrophobic channel of the NNRTI-binding pocket. The biological evaluation results showed that most of the compounds displayed effective inhibitory potency against the HIV-1 wild-type strain, with EC50 values ranging from micromolar to submicromolar levels. Among them, TT6 turned out to be the most effective inhibitor with an EC50 value of 0.17 μM, demonstrating up to 47 times more active than that of reference drug 3TC (EC50 = 8.01 μM). More encouragingly, TT6 was found to potently inhibit the HIV-1 mutant strain K103N with an EC50 value of 0.69 μM, being about 6-fold more potent than 3TC (EC50 = 3.68 μM) and NVP (EC50 = 4.62 μM). Furthermore, TT6 exhibited the most potent inhibitory activity toward HIV-1 reverse transcriptase with an IC50 value of 0.33 μM. Additionally, molecular simulation studies were conducted to investigate the binding modes between TT6 and NNRTI-binding pocket, which may provide valuable clues for the follow-up structural optimizations.

Abstract
This study presents proof of concept for designing a novel HIV-1 covalent inhibitor targeting the highly conserved Tyr318 in the HIV-1 non-nucleoside reverse transcriptase inhibitors binding pocket to improve the drug resistance profiles. The target inhibitor ZA-2 with a fluorosulfate warhead in the structure was found to be a potent inhibitor (EC50 = 11-246 nM) against HIV-1 IIIB and a panel of NNRTIs-resistant strains, being far superior to those of NVP and EFV. Moreover, ZA-2 was demonstrated with lower cytotoxicity (CC50 = 125 µM). In the reverse transcriptase inhibitory assay, ZA-2 exhibited an IC50 value of 0.057 µM with the ELISA method, and the MALDI-TOF MS data demonstrated the covalent binding mode of ZA-2 with the enzyme. Additionally, the molecular simulations have also demonstrated that compounds can form covalent binding to the Tyr318.

Abstract
Herein, alkenylpiperidine and alkynylpiperidine moieties were introduced into the left wing of DAPYs (diarylpyrimidines) to explore the new site of the NNIBP (non-nucleoside inhibitor binding pocket) protein-solvent interface region via the structure-based drug design strategy. All the synthesized compounds displayed nanomolar to submicromolar activity against WT (wild-type) HIV-1. Among all, compound FT1 (EC50 = 19 nM) was found to be the most active molecule, which is better than NVP (EC50 = 0.10 μM). In addition, most of the compounds displayed micromolar activity against K103N and E138K mutant strains, while FT1 (EC50(K103N) = 50 nM, EC50(E138K) = 0.19 µM) still has the most effective activity. The molecular dynamics simulation studies revealed that the presence of pyridine moiety of FT1 was essential and played a significant role in its binding with RT (reverse transcriptase).

Abstract
Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are widely used in combination therapies against HIV-1. As a continuation of our efforts to discover and develop "me-better" drugs of DAPYs, novel diarylpyrimidine derivatives were designed, synthesized and evaluated for their anti-HIV activities in MT-4 cells. All the compounds demonstrated strong inhibition activity against wide-type HIV-1 strain (IIIB) with EC50 values in the range of 2.5 nM ~ 0.93 μM. Among them, compounds IVB-5-4 and IVB-5-8 were the most potent ones which showed anti-HIV-1IIIB activity much superior than that of Nevirapine, comparable to Efavirenz and Etravirine. What's more, some compounds also showed low nanomole activity against some mutant strains such as K103N and E138K. The selected compound IVB-5-4 was also evaluated for the activity against reverse transcriptase (RT), and exhibited submicromolar IC50 values indicating that this series compounds are specific RT inhibitors. Preliminary structure-activity relationships and modeling studies of these new analogues provide valuable avenues for future molecular optimization.

Abstract
Fifteen naphthyl-carboxamide-DAPYs were generated to explore chemical space in reverse transcriptase (RT) binding site via lead optimization strategy. They displayed up to single-digit nanomolar activity against wild-type (WT) and rilpivirine-associated resistant mutant E138K viruses, as well as potent inhibitory ability toward the RT enzyme. Compound a1 showed exceptionally inhibitory effects with an EC50 value of 3.7 nM against HIV-1 wt strain, and an EC50 of 11 nM targeting mutant E138K. The structure-activity relationships (SARs) of the newly obtained DAPYs were also investigated. Molecular docking analysis elucidated the biological activity and offered a structural insight for follow-up research.

Abstract
Human immunodeficiency virus (HIV) is the primary infectious agent of acquired immunodeficiency syndrome (AIDS), and non-nucleoside reverse transcriptase inhibitors (NNRTIs) are the cornerstone of HIV treatment. In the last 20 years, our medicinal chemistry group has made great strides in developing several distinct novel NNRTIs, including 1-[(2-hydroxyethoxy)methyl]-6-(phenylthio)thymine (HEPT), thio-dihydro-alkoxy-benzyl-oxopyrimidine (S-DABO), diaryltriazine (DATA), diarylpyrimidine (DAPY) analogues, and their hybrid derivatives. Application of integrated modern medicinal strategies, including structure-based drug design, fragment-based optimization, scaffold/fragment hopping, molecular/fragment hybridization, and bioisosterism, led to the development of several highly potent analogues for further evaluations. In this paper, we review the development of NNRTIs in the last two decades using the above optimization strategies, including their structure–activity relationships, molecular modeling, and their binding modes with HIV-1 reverse transcriptase (RT). Future directions and perspectives on the design and associated challenges are also discussed.

Abstract
Twenty-seven derivatives (40-66) were generated by pharmacophore fusing of sulfonylacetanilide-diarylpyrimidine (1) with rilpivirine or biphenyl-diarylpyrimidines. They displayed up to single-digit nanomolar activity against wild-type (WT) virus and various drug-resistant mutant strains in HIV-1-infected MT-4 cells, thereby targeting the reverse transcriptase (RT) enzyme. Compound 51 displayed exceptionally potent activity against WT virus (EC50 = 6 nM) and several mutant strains (L100I, EC50 = 8 nM, K103N, EC50 = 6 nM, Y181C, EC50 = 26 nM, Y188L, EC50 = 122 nM, E138K, EC50 = 26 nM). The structure-activity relationships of the newly obtained pyrimidine sulfonylacetanilides were also elucidated. Molecular docking analysis explained the activity and provided a structural insight for follow-up research.

All of the molecules were active against wild-type HIV-1 with EC50 values ranging from 0.61 μM to 0.84 nM. The most potent inhibitor, compound 4b, had an EC50 value of 0.84 nM against HIV-1 strain IIIB, and thus was more active than the reference drugs efavirenz and etravirine. Moreover, most of the compounds maintained high activity (low-micromolar EC50 values) against strains bearing the reverse transcriptase (RT) E138K mutation. Compound 4b had EC50 values of 3.5 nM and 66 nM against non-nucleoside reverse transcriptase inhibitor-resistant strains bearing the RT E138K and RES056 mutations. In enzyme activity assays, compound 4b exhibited an IC50 value of 10 nM against HIV-1 RT. Preliminary SARs and molecular docking studies provide valuable insights for further optimization.

Abstract
Diarylpyrimidines (DAPYs), a type of effective HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs), have been considered as one of the most successful agents for treating AIDS. A number of structurally diverse DAPYs have been designed and synthesized in the past decade, and most of them exhibited potent anti-HIV-1 activities; however, the structure-activity relationships of recently reported DAPYs and their pharmacophore features that interacted with HIV-1 reverse transcriptase (RT) remain to be studied. In the present study, molecular docking studies were first performed on three novel classes of DAPYs to study their binding pattern in the HIV-1 RT. Based on the docking conformations of these DAPYs, 3D-QSAR models were constructed using CoMSIA and Topomer CoMFA methods, and pharmacophore models were also built using distance comparison technique. All selected DAPYs presented preferred U- or L-shaped conformations while being docked into the non-nucleoside inhibitor-binding pocket of the HIV-1 RT. The best CoMSIA model exhibited powerful predictivity, with satisfactory statistical parameters such as a q2 of 0.572, an r2 of 0.952, and an [Formula: see text] of 0.728. Contour maps of the best CoMSIA model were in accordance with those of the Topomer CoMFA model, giving the insight into the feature requirements of DAPYs for the anti-HIV-1 activity. Three potential pharmacophore models were constructed, and each of them was consisted of five hypothesis features. All results suggested that the aromatic ring on the left wing of DAPYs and the central pyrimidine ring contained key pharmacophore features for the anti-HIV-1 activity, and also indicated that the right wing of DAPYs had potential for further structural modification to improve activity. Eight novel DAPY molecules with potential anti-HIV-1 activities were designed on the basis of the obtained results. The findings in this study might provide important information for further design and development of novel HIV-1 NNRTIs.

Abstract
Non-nucleoside reverse transcriptase inhibitors (NNRTIs) play a significant role in anti-HIV drug development. A series of naphthyl-substituted diarylpyrimidines with most EC50 values in the nanomolar range was reported as potent NNRTIs by our lab. In order to obtain the quantitative structure-activity relationship (QSAR) that can guide rational lead optimization, CoMFA and CoMSIA studies were carried out. Docking study based on the co-crystallized complex (PDB ID: 3MEC) was utilized as an approach to obtain reliable conformations for molecular alignment. Two different molecular alignments were performed, resulting in two CoMFA models and 34 CoMSIA models. The CoMSIA models correspond to all the possible combinations among five fields: steric, electrostatic, hydrophobic, hydrogen bond donor, and hydrogen bond acceptor. Highly predictive models were achieved, in which the statistically reliable CoMFA model had a q(2) of 0.743 and an r(2) of 0.980, whereas the best CoMSIA model had a q(2) of 0.713 and an r(2) of 0.969. The best models were rigorously validated with an external test set, which gave satisfactory predictive r(2) values for CoMFA and CoMSIA models: 0.85 and 0.83, respectively. Contour maps obtained from selected models revealed important structural features and some rational guidance for further optimization.
