Abstract
Non-nucleoside reverse transcriptase inhibitors (NNRTIs) have always been an important part of the anti-HIV-1 combination therapy known as combination antiretroviral therapy (cART) since 1996. The use of NNRTIs for about 22 years has led to some mutations in the residues that compose the reverse transcriptase active site, resulting in the emergence of drug-resistant viruses. Thus, the search for new potent NNRTIs with an improved safety profile and activity against drug-resistant HIV strains is indispensable, and many hit and lead NNRTIs have been discovered in the last decade. This review provides an overview of the development in this field from 2013 to August 2018.

Discovery of novel piperidine-substituted indolylarylsulfones as potent HIV NNRTIs via structure-guided scaffold morphing and fragment rearrangement. Eur J Med Chem 2016; 126:190-201.

Abstract
To further explore the chemical space around the entrance channel of HIV-1 reverse transcriptase (RT), a series of novel indolylarylsulfones (IASs) bearing N-substituted piperidine at indole-2-carboxamide were identified as potent HIV NNRTIs by structure-guided scaffold morphing and fragment rearrangement. All the IASs exhibited moderate to excellent potency against wild-type HIV-1 with EC50 values ranging from 0.62 μM to 0.006 μM 8 (EC50 = 6 nM) and 18 (EC50 = 9 nM) were identified as the most potent compounds, which were more active than NVP and DLV, and reached the same order of EFV and ETV. Furthermore, most compounds maintained high activity agaist various single HIV-1 mutants (L100I, K103N, E138K, Y181C) as well as one double mutant (F227L/V106A) with EC50 values in low-micromolar to double-digit nanomolar concentration ranges. Especially, 8 displayed outstanding potency against L100I (EC50 = 17 nM with a 2.8-fold resistance ratio) and 18 was relatively more potent to E138K mutant (EC50 = 43 nM with a 4.7-fold resistance ratio). Preliminary SARs and molecular modeling studies were also discussed in detail, which may provide valuable insights for further optimization.

Abstract
We designed and synthesized a series of human immunodeficiency virus type 1 (HIV-1) non-nucleoside reverse transcriptase inhibitors (NNRTIs) with a piperidine-substituted thiophene[3,2-d]pyrimidine scaffold, employing a strategy of structure-based molecular hybridization and substituent decorating. Most of the synthesized compounds exhibited broad-spectrum activity with low (single-digit) nanomolar EC50 values toward a panel of wild-type (WT), single-mutant, and double-mutant HIV-1 strains. Compound 27 was the most potent; compared with ETV, its antiviral efficacy was 3-fold greater against WT, 5-7-fold greater against Y181C, Y188L, E138K, and F227L+V106A, and nearly equipotent against L100I and K103N, though somewhat weaker against K103N+Y181C. Importantly, 27 has lower cytotoxicity (CC50 > 227 μM) and a huge selectivity index (SI) value (ratio of CC50/EC50) of >159101. 27 also showed favorable, drug-like pharmacokinetic and safety properties in rats in vivo. Molecular docking studies and the structure-activity relationships provide important clues for further molecular elaboration.

Abstract
Diarylpyrimidine and diaryltriazine derivatives, two representative structurally related classes of HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs) with robust potencies against wild-type and several mutant strains of HIV-1, have attracted more and more attention in the last decade. However, they have been suffering from poor aqueous solubility. A series of novel diarylpyrimidines and diaryltriazines with solubilizing substituents attached to the central rings were reported as potent NNRTIs in the patent US20140378443A1. Some compounds exhibited potencies against wild-type HIV-1 which were comparable or even superior to those of dapivirine, etravirine and rilpivirine. In addition, dramatically enhanced solubilities were observed for these new compounds. Moreover, some structure optimization strategies for improving aqueous solubility are detailed in this review, providing new insights into development of next-generation NNRTIs endowed with favorable solubility. We anticipate that application of these strategies will ultimately lead to discovery of new anti-HIV drug candidates.

Abstract
We have developed a series of N(2) -(1-(substituted-aryl)piperidin-4-yl)-N(6) -mesityl-9H-purine-2,6-diamine derivatives as potent antiviral agents. Preliminary biological evaluation indicated that nearly half of them possessed remarkable HIV inhibitory potencies in cellular assays. In particular, FZJ13 appeared to be the most notable one, which displayed anti-HIV-1 activity compared to 3TC. Moreover, an unexpected finding was that FZJ05 displayed significant potency against influenza A/H1N1 (strain A/PR/8/34) in Madin-Darby canine kidney cells with EC50 values much lower than those of ribavirin, amantadine, and rimantadine. The results suggest that these novel purine derivatives have the potential to be further developed as new therapeutic agents against HIV-1 or influenza virus.

Abstract
A novel series of triazine derivatives targeting the entrance channel of the HIV-1 non-nucleoside reverse transcriptase inhibitor binding pocket (NNIBP) were designed and synthesized on the basis of our previous work. The results of a cell-based antiviral screening assay indicated that most compounds showed good-to-moderate activity against wild-type HIV-1 with EC50 values within the concentration range of 0.0078-0.16 μm (compound DCS-a4, EC50 = 7.8 nm). Some compounds displayed submicromolar activity against the K103N/Y181C resistant mutant strain (such as compound DCS-a4, EC50 = 0.65 μm). Molecular modeling studies confirmed that the new compounds could bind into the NNIBP similarly as the lead compound, and the newly introduced flexible heterocycles could occupy the entrance channel effectively. In addition, the preliminary structure-activity relationship and the RT inhibitory assay are presented in this study.

Abstract
Based on the hybridization of the privileged fragments in DABO and DAPY-typed HIV-1 NNRTIs, a novel series of 4-aminopiperidinyl-linked 3,5-disubstituted-1,2,6-thiadiazine-1,1-dione derivatives were designed, synthesized, and evaluated for their in vitro anti-HIV activities in MT-4 cells. Most of the target compounds showed weak inhibitory activity against WT HIV-1. In order to confirm the mode of action of the target compounds, representative compounds Ba8 and Bb8 were selected to perform the HIV-1 RT inhibitory assay. In this assay, Ba8 and Bb8 displayed good activity with IC50 values of 3.15 and 1.52 μm, respectively. Additionally, preliminary structure-activity relationships (SARs) analysis and molecular docking studies of newly synthesized compounds are also discussed.

Abstract
A novel series of 3-benzyloxy-linked pyrimidinylphenylamine derivatives (8a-8s) was designed, synthesized and evaluated for their in vitro anti-HIV activity in MT-4 cell cultures. Most of the compounds inhibited wild-type (wt) HIV-1 replication in the lower micromolar concentration range (EC(50)=0.05-35 μM) with high selectivity index (SI) values (ranged from 10 to >4870). In particular, 8h and 8g displayed excellent antiretroviral activity against wt HIV-1 with low cytotoxicity (EC(50)=0.07 μM, CC(50) >347 μM, SI >4870; EC50=0.05 μM, CC(50)=42 μM, SI=777, respectively), comparable to that of the marked drug nevirapine (EC(50)=0.113 μM, CC(50) >15 μM, SI >133). In order to confirm the binding target, 8h was selected to perform the anti-HIV-1 RT assay. Additionally, preliminary structure activity relationship (SAR) analysis and molecular docking studies of newly synthesized compounds were also discussed, as well as the predicted physicochemical properties.
