Abstract
Drug discovery of human immunodeficiency virus (HIV) is a hot field in medicinal chemistry community for many years. The diarylpyrimidines (DAPYs) are the second-generation non-nucleoside reverse transcriptase inhibitors (NNRTIs) targeting reverse transcriptase, playing a great irreplaceable role in HIV transcriptional therapy. However, fast-growing drug-resistant mutations as nonnegligible challenge are still unpredictably appeared in the clinical practice, leading to deactivate or reduce the existing drugs. In the last 20 years, more and more novel DAPY derivatives have developed with the purpose to counter the mutants. Nevertheless, most of them have dissatisfactory pharmacokinetics (PK) or poor antiviral activity toward resistant mutant strains. In this article, we will analyze the NNRTI derivatives with promising druggability, and summarize a series of druggability modification strategies to improve the antiviral activity, reduce toxicity and improve the PK properties in recent years. The prospects of DAPYs and the directions for future efforts will be discussed.

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.

Abstract
HIV-1 nonnucleoside reverse transcriptase inhibitors (NNRTIs) have been playing an important role in the fight against acquired immunodeficiency syndrome (AIDS). Diarylpyrimidines (DAPYs) as the second generation NNRTIs, represented by etravirine (TMC125) and rilpivirine (TMC278), have attracted extensive attention due to their extraordinary potency, high specificity and low toxicity. However, the rapid emergence of drug-resistant virus strains and dissatisfactory pharmacokinetics of DAPYs present new challenges. In the past two decades, an increasing number of novel DAPY derivatives have emerged, which significantly enriched the structure-activity relationship of DAPYs. Studies of crystallography and molecular modeling have afforded a lot of useful information on structural requirements of NNRTIs, which contributes greatly to the improvement of their resistance profiles. In this review, we reviewed the discovery history and their evolution of DAPYs including their structural modification, derivatization and scaffold hopping in continuous pursuit of excellent anti-HIV drugs. And also, we discussed the prospect of DAPYs and the directions of future efforts.

Abstract
INTRODUCTION To deal with the rapid emergence of drug resistance challenges, together with the difficulty to eradicate the virus, off-target effects and significant cumulative drug toxicities, it is still imperative to develop next-generation anti-HIV agents with novel chemical classes or new mechanisms of action. AREAS COVERED We primarily focused on current strategies to discover novel anti-HIV agents. Moreover, examples of anti-HIV lead compounds were mainly selected from recently patented publications (reported between 2014 and 2017). In particular, 'privileged structure'-focused substituents decorating approach, scaffold hopping, natural-product diversification and prodrug are focused on. Furthermore, exploitation of new compounds with unexplored mechanisms of action and medicinal chemistry strategies to deplete the HIV reservoir were also described. Perspectives that could inspire future anti-HIV drug discovery are delineated. EXPERT OPINION Even if a large number of patents have been disclosed recently, additional HIV inhibitors are still required, especially novel chemical skeletons displaying a unexploited mechanism of action. Current medicinal chemistry strategies are inadequate, and appropriate and new methodologies and technologies should be exploited to identify novel anti-HIV drug candidates in a time- and cost- effective manner.

Abstract
Based on the strategy of molecular hybridization, diketo acid fragment as a classical phamacophore of integrase inhibitors was introduced to reverse transcriptase inhibitors diarylpyrimidines to design a series of diarylpyrimidine-diketo acid hybrids (DAPY-DKAs). The target molecules 10b and 11b showed inhibitory activities against WT HIV-1 with EC50 values of 0.18μM and 0.14μM, respectively. And the results of molecular docking demonstrated the potential binding mode and revealed that the DKA moiety and its ester could both be tolerated in the nonnucleoside binding site (NNBS) of HIV-1 RT.

Abstract
Diaryltriazine derivatives, which are structurally related to diarylpyrimidines, are a representative class of HIV-1 reverse transcriptase inhibitors with remarkable antiviral activities against wild-type and several mutant strains of HIV-1. A series of novel diaryltriazines with a picolinonitrile moiety was reported as potent HIV-1 RT inhibitors in the patent WO2016059647(A2). Two representative compounds 5e (hydrochloride) and 6e (hydrochloride) exhibited outstanding activities against various HIV-1 strains in cell-based assays, which were superior to those of AZT. Moreover, modeling simulation study is performed and discussed in details, providing deep insights and valuable information to explain the excellent antiviral potency of 6e. Finally, several cases to improve anti-drug-resistance profiles by targeting highly conserved residues in HIV-1 RT are herein preliminarily summarized.

Abstract
INTRODUCTION In recent years, a variety of new synthetic methodologies and concepts have been proposed in the search for new pharmaceutical lead structures and optimization. Notably, the Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) click chemistry approach has drawn great attention and has become a powerful tool for the generation of privileged medicinal skeletons in the discovery of anti-HIV agents. This is due to the high degree of reliability, complete specificity (chemoselectivity and regioselectivity), mild conditions, and the biocompatibility of the reactants. AREAS COVERED Herein, the authors describe the progress thus far on the discovery of novel anti-HIV agents via the CuAAC click chemistry-based approach. EXPERT OPINION CuAAC click chemistry is a proven protocol for synthesizing triazole products which could serve as basic pharmacophores, act as replacements of traditional scaffold or substituent modification, be a linker of dual-target or dual-site inhibitors and more for the discovery of novel anti-HIV agents. What's more, it also provides convenience and feasibility for dynamic combinatorial chemistry and in situ screening. It is envisioned that click chemistry will draw more attention and make more contributions in anti-HIV drug discovery in the future.

Abstract
Based on the crystallographic studies of diarylpyrimidines (DAPYs), we embarked on incorporating the hydrophilic piperidyl or morpholinyl group into the known DAPY derivatives bearing the pyridine moiety as a core structure, with the double aim to exploit additional interactions with the HIV-1 NNRTI binding pocket (NNIBP), as well as to improve the compound solubility. The antiviral evaluation result show that the most potent compounds I-8b2, I-8b3, I-8b4 and I-8c3 exhibited anti-HIV-1 (IIIB) strain activity ranging from 7.4 nM to 9.4 nM (SI = 168-1283), superior to FDA-approved drugs of nevirapine (NVP), lamivudine (3TC) and delavirdine (DLV), and comparable to etravirine (ETV), zidovudine (AZT) and efavirenz (EFV). Additionally, compounds I-8c2 and I-8c3 showed moderate activity against NNRTI resistant strains baring mutations K103N and Y181C with EC50 values of 6.2 μM and 6.8 μM, respectively. Preliminary structure-activity relationships (SARs), reverse transcriptase inhibition efficacy and molecular modeling of selected compounds are also presented. These outcomes support our design hypothesis and demonstrate that the piperidyl group modified pyridine-typed DAPY derivatives are highly potent NNRTIs with improved water solubility.

Abstract
The development of novel NNRTIs with activity against variants of HIV-1RT is crucial for overcoming treatment failure. In the present study, a series of novel 6-substituted diarylpyridine derivatives targeting the entrance channel of the NNIBP of RT were designed through a molecular hybridization strategy. Encouragingly, these new diarylpyridine derivatives were found to be active against wild-type (WT) HIV-1 with an EC50 values ranging from 0.035 μM to 1.99 μM. Nearly half of them exhibited more potent inhibitory activities in cellular assays than the control drug nevirapine (NVP). Notably, three most promising compounds If (EC50 = 35 nM), Ia (EC50 = 43 nM) and IIa (EC50 = 41 nM) showed high potency against WT and were comparable to the reference drug delavirdine (DLV) (EC50 = 33 nM). Moreover, compounds Ib, IIb and IIh displayed effective activity against the most common clinically observed single and double-mutated HIV-1 strains in micromolar concentrations. In particular, the inhibition of IIb against the K103N mutation (EC50 = 49 nM), which confers resistance to a wide variety of NNRTIs, was about 140 times more effective than NVP (EC50 = 6.78 μM), 50 times more than DLV (EC50 = 2.48 μM) and about 3 times more than EFV (EC50 = 0.12 μM), indicating that the newly designed compounds have great potential to be further developed as new anti-HIV-1 agents. Preliminary structure-activity relationships (SARs) and molecular modeling of the new diarylpyridine derivatives were discussed in detail.

Abstract
The SNAr reaction of 2,4-dichloropyrimidines, further substituted with an electron-withdrawing substituent at C-5, has selectivity for substitution at C-4. Here we report that tertiary amine nucleophiles show excellent C-2 selectivity. In situ N-dealkylation of an intermediate gives the product that formally corresponds to the reaction of a secondary amine nucleophile at C-2. This reaction is practical (fast under simple reaction conditions, with good generality for tertiary amine structure and moderate to excellent yields) and significantly expands access to pyrimidine structures.

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
Through a structure-based molecular hybridization approach, a novel series of diarylnicotinamide derivatives (DANAs) targeting the entrance channel of HIV-1 NNRTIs binding pocket (NNIBP) were rationally designed, synthesized and evaluated for their anti-HIV activities in MT-4 cells together with the inhibition against the reverse transcriptase (RT) in an enzymatic assay. Encouragingly, most of the new DANAs were found to be active against wild-type HIV-1 with an EC50 in the range of 0.027-4.54 μM. Among them, compound 6b11 (EC50 = 0.027 μM, SI > 12518) and 6b5 (EC50 = 0.029 μM, SI = 2471) were identified as the most potent inhibitors, which were more potent than the reference drugs nevirapine (EC50 = 0.31 μM) and delavirdine (EC50 = 0.66 μM). Some DANAs were also active at micromolar concentrations against the K103N + Y181C resistant mutant. Compound 6b11 exhibited the highest enzymatic inhibition activity (IC50 = 20 nM), which is equal to that of efavirenz (EC50 = 20 nM) and 31 times higher than that of nevirapine (EC50 = 0.62 μM). Preliminary structure-activity relationships (SARs) and molecular modeling of these new DANAs have been discussed.
