Abstract
AIDS (acquired immunodeficiency syndrome) is a potentially life-threatening infectious disease caused by human immunodeficiency virus (HIV). To date, thousands of people have lost their lives annually due to HIV infection, and it continues to be a big public health issue globally. Since the discovery of the first drug, Zidovudine (AZT), a nucleoside reverse transcriptase inhibitor (NRTI), to date, 30 drugs have been approved by the FDA, primarily targeting reverse transcriptase, integrase, and/or protease enzymes. The majority of these drugs target the catalytic and allosteric sites of the HIV enzyme reverse transcriptase. Compared to the NRTI family of drugs, the diverse chemical class of non-nucleoside reverse transcriptase inhibitors (NNRTIs) has special anti-HIV activity with high specificity and low toxicity. However, current clinical usage of NRTI and NNRTI drugs has limited therapeutic value due to their adverse drug reactions and the emergence of multidrug-resistant (MDR) strains. To overcome drug resistance and efficacy issues, combination therapy is widely prescribed for HIV patients. Combination antiretroviral therapy (cART) includes more than one antiretroviral agent targeting two or more enzymes in the life cycle of the virus. Medicinal chemistry researchers apply different optimization strategies including structure- and fragment-based drug design, prodrug approach, scaffold hopping, molecular/fragment hybridization, bioisosterism, high-throughput screening, covalent-binding, targeting highly hydrophobic channel, targeting dual site, and multi-target-directed ligand to identify and develop novel NNRTIs with high antiviral activity against wild-type (WT) and mutant strains. The formulation experts design various delivery systems with single or combination therapies and long-acting regimens of NNRTIs to improve pharmacokinetic profiles and provide sustained therapeutic effects.

Abstract
Aim: To develop lipid nano-antiretrovirals (LNAs) for the treatment of HIV-infected macrophages. Materials & methods: LNAs were prepared with docosahexaenoic acid to facilitate brain penetration and surface-decorated with folate considering that infected macrophages often overexpress folate receptors. Results: Folate-decorated LNAs loading rilpivirine (RPV) were efficiently taken up by folate receptor-expressing cell types including activated macrophages. The intracellular Cmax of the RPV-LNAs in activated macrophages was 2.54-fold and the area under the curve was 3.4-fold versus free RPV, translating to comparable or higher (p < 0.01; RPV ≤6.5 ng/ml) activities against HIV infectivity and superior protection (p < 0.05) against HIV cytotoxicity. LNAs were also effective in monocyte-derived macrophages. Conclusion: These findings demonstrate the potential of LNAs for the treatment of infected macrophages, which are key players in HIV reservoirs.

Abstract
Objective: To review the efficacy and safety of cabotegravir (CAB) with rilpivirine (RPV) in the treatment of HIV-1 infection. Data Sources: A literature search was performed using PubMed and Google Scholar (2010 to January 2021) with the search terms cabotegravir and rilpivirine. Other resources included abstracts presented at recent conferences and the manufacturer’s website and prescribing information. Study Selection: All English-language articles of studies assessing the efficacy and safety of CAB with RPV were included. Data Synthesis: The combination of CAB, a new integrase strand transfer inhibitor, and RPV, an established nonnucleoside reverse transcriptase inhibitor, is the first long-acting dual therapy approved for the treatment of HIV-1 infection in adults who have achieved viral suppression on a standard antiretroviral therapy (ART). This regimen demonstrated comparable maintenance of viral suppression evaluated up to 160 weeks, with low rates of virological failure. CAB and RPV are available as suspension given intramuscularly in 2 separate injections every 4 weeks. Common adverse effects include injection site reactions, pyrexia, fatigue, and headache. CAB and RPV are also available as tablets given orally for bridging therapy. Relevance to Patient Care and Clinical Practice: This long-acting dual therapy represents an attractive option with a high barrier to resistance for adults who have achieved viral suppression on standard ART and who prefer monthly injections over daily oral therapy. Conclusions: CAB-RPV is the first complete long-acting injectable that provides a convenient way to maintain viral suppression with no negative effects on renal and bone health and few drug interactions.

Abstract
The non-nucleoside reverse transcriptase inhibitors (NNRTIs) are allosteric inhibitors of HIV-1 reverse transcriptase and are classified into generations depending on their discovery and resistance profiles. The NNRTIs are used in combination regimens with antiretroviral agents that target two or more enzymes in the viral life cycle. The combination regimens usually include a backbone of two nucleoside or nucleotide reverse transcriptase inhibitors and a third core agent among the NNRTIs or protease inhibitors. The combination regimens are maintained over long durations and consequently lead to long-term problems, including toxicity, drug-drug interactions, and increasing costs. This brief overview summarizes the pharmacokinetic profiles for NNRTIs and NNRTI-based combination regimens.

Abstract
Background:
S-dihydro-alkyloxy-benzyl-oxopyrimidines (S-DABOs) as non-nucleoside
reverse transcriptase inhibitors have received considerable attention during the last decade due to
their high potency against HIV-1.
Methods:
In this study, three-dimensional quantitative structure-activity relationship (3D-QSAR) of
a series of 38 S-DABO analogues developed in our lab was studied using Comparative Molecular
Field Analysis (CoMFA) and Comparative Molecular Similarity Indices Analysis (CoMSIA). The
Docking/MMFF94s computational protocol based on the co-crystallized complex (PDB ID: 1RT2)
was used to determine the most probable binding mode and to obtain reliable conformations for
molecular alignment. Statistically significant CoMFA (q2=0.766 and r2=0.949) and CoMSIA
(q2=0.827 and r2=0.974) models were generated using the training set of 30 compounds on the basis
of hybrid docking-based and ligand-based alignment.
Results:
The predictive ability of CoMFA and CoMSIA models was further validated using a test
set of eight compounds with predictive r2
pred values of 0.843 and 0.723, respectively.
Conclusion:
The information obtained from the 3D contour maps can be used in designing new SDABO
derivatives with improved HIV-1 inhibitory activity.

Abstract
In this study, 48 inhibitors were docked to 107 allosteric centers of human immunodeficiency virus 1 (HIV-1) reverse transcriptase from the Protein Data Bank (PDB). Based on the average binding scores, quantitative structure-activity relationship (QSAR) equations were constructed in order to elucidate directions of further development in the design of inhibitors. Such developments, informed by structural data, must have a focus on activity against mutated forms of the enzyme, which are the cause of the emergence of multidrug-resistant viral strains. Docking studies employed the HYDE scoring function. Two types of QSARs have been considered: One based on topological descriptors and the other on structural fragments of the inhibitors. Both methods gave similar results, indicating substructures favoring binding to mutated forms of the enzyme.

Abstract
The clinical benefits of HIV-1 non-nucleoside reverse transcriptase (RT) inhibitors (NNRTIs) are hindered by their unsatisfactory pharmacokinetic (PK) properties along with the rapid development of drug-resistant variants. However, the clinical efficacy of these inhibitors can be improved by developing compounds with enhanced pharmacological profiles and heightened antiviral activity. We used computational and structure-guided design to develop two next-generation NNRTI drug candidates, compounds I and II, which are members of a class of catechol diethers. We evaluated the preclinical potential of these compounds in BALB/c mice because of their high solubility (510 µg/ml for compound I and 82.9 µg/ml for compound II), low cytotoxicity, and enhanced antiviral activity against wild-type (WT) HIV-1 RT and resistant variants. Additionally, crystal structures of compounds I and II with WT RT suggested an optimal binding to the NNRTI binding pocket favoring the high anti-viral potency. A single intraperitoneal dose of compounds I and II exhibited a prolonged serum residence time of 48 hours and concentration maximum (Cmax) of 4000- to 15,000-fold higher than their therapeutic/effective concentrations. These Cmax values were 4- to 15-fold lower than their cytotoxic concentrations observed in MT-2 cells. Compound II showed an enhanced area under the curve (0-last) and decreased plasma clearance over compound I and efavirenz, the standard of care NNRTI. Hence, the overall (PK) profile of compound II was excellent compared with that of compound I and efavirenz. Furthermore, both compounds were very well tolerated in BALB/c mice without any detectable acute toxicity. Taken together, these data suggest that compounds I and II possess improved anti-HIV-1 potency, remarkable in vivo safety, and prolonged in vivo circulation time, suggesting strong potential for further development as new NNRTIs for the potential treatment of HIV infection.

Abstract
Microbicides are being developed in order to prevent sexual transmission of HIV. Dapivirine, a non-nucleoside reverse transcriptase inhibitor, is one of the leading drug candidates in the field, currently being tested in various dosage forms, namely vaginal rings, gels, and films. In particular, a ring allowing sustained drug release for 1month is in an advanced stage of clinical testing. Two parallel phase III clinical trials are underway in sub-Saharan Africa and results are expected to be released in early 2016. This article overviews the development of dapivirine and its multiple products as potential microbicides, with particular emphasis being placed on clinical evaluation. Also, critical aspects regarding regulatory approval, manufacturing, distribution, and access are discussed.

Abstract
OBJECTIVES Traditionally, the antiviral efficacy of classic cocktail therapy is significantly limited by the distinct pharmacokinetic profiles of partner therapeutics that lead to inconsistent in-vivo biodistribution. Here we developed a new cocktail-like drug delivery vehicle using biodegradable polymeric nanoparticles (NP) encapsulating nonnucleoside reverse transcriptase inhibitor (NNRTI) DAAN-14f (14f), surface-conjugated with HIV-1 fusion inhibitor T1144, designated T1144-NP-DAAN-14f (T1144-NP-14f), and aiming to achieve enhanced cellular uptake, improved antiviral activity and prolonged blood circulation time. METHODS T1144-NP-14f was prepared through the emulsion/solvent evaporation technique and a maleimide-thiol coupling reaction. Particle size and morphology were determined by dynamic light scattering detection and transmission electron microscopy. Anti-HIV-1 activity was assessed by HIV-1 Env-mediated cell-cell fusion and infection by laboratory-adapted, primary, and resistant HIV-1 isolates, respectively. The in-vitro release of 14f was investigated using the equilibrium dialysis method, and the pharmacokinetic study of T1144-NP-14f was performed on Sprague-Dawley rats. RESULTS T1144-NP-14f displayed a spherical shape under transmission electron microscopy observation and had a size of 117 ± 19 nm. T1144-NP-14f exhibited the strongest antiviral activity against a broad spectrum of HIV-1 strains, including NNRTI-, T1144-, or T20-resistant isolates, respectively. Both in-vitro release and in-vivo pharmacokinetic profile showed that T1144-NP-14f exhibited a sustained controlled release behavior. CONCLUSION Our results demonstrated that the combination of entry inhibitor with NNRTI encapsulated in nanoparticles (T1144-NP-14f) was highly effective in inhibiting HIV-1 infection. This new cocktail-like drug delivery platform could serve as an effective anti-HIV-1 regimen by taking advantage of the extrinsic and intrinsic antiviral activity of individual drugs.

Abstract
In the present investigation, a simple and isocratic HPLC-UV method was developed and validated for determination of rilpivirine (RPV) from dosage forms (tablets and nanoparticles) and biological matrices like HeLa cell lysates. The separation and analysis of RPV was carried out under isocratic conditions using (a) a Gemini reversed-phase C18 column (5 µm; 4.6 × 150 mm) maintained at 35°C, (b) a mobile phase consisting of a mixture of acetonitrile and 25 m m potassium dihydrogen phosphate (in the ratio 50:50 v/v) at a flow rate of 0.6 mL/min and (c) atazanavir as an internal standard. The total run time was 17 min and the analysis of RPV and internal standard was carried out at 290 nm. The method was found to be linear (r(2) value > 0.998), specific, accurate and precise over the concentration range of 0.025-2 µg/mL. The lower limit of quantification was 0.025 µg/mL, the limit of detection was 0.008 µg/mL and the recovery of RPV was >90%. The stability of the RPV analytical method was confirmed at various conditions such as room temperature (24 h), -20°C (7 days), three freeze-thaw cycles and storage in an autosampler (4°C for 48 h). The method was successfully applied for the determination of RPV from conventional dosage forms like tablets, from polymeric nanoparticles and from biological matrices like HeLa cell lysates.

Abstract
Novel 2,4,5-trisubstituted thiazole derivatives (TSTs) were designed and synthesized as HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs). Among the thirty-eight synthesized target compounds, thirty TSTs showed potent inhibition against HIV-1 replication in wild type HIV-1 at submicromolar concentrations (from 0.046 to 9.59 μM). Compounds 21, 23 and 24 were also tested on seven NNRTI-resistant HIV-1 strains, and all exhibited inhibitory effects with fold changes in IC50 ranging from 2.6 to 111, which were better than those of nevirapine (15.6-fold-371-fold). Docking simulations of compound 24 revealed a reasonable mechanism for the binding mode, and three-dimensional quantitative structure activity relationship (3-DQSAR) studies on this novel series of TST further elucidated the structure-activity relationship (SAR). The results suggested the great potential of TSTs as a novel class of NNRTIs with antiviral efficacy and a good resistance profile.

Abstract
Nonnucleoside reverse transcriptase inhibitors (NNRTIs) are important and frequently used elements of highly active antiretroviral therapy (HAART) for the treatment of human immunodeficiency virus type 1 (HIV-1) infection. However, the development of drug resistance, as well as the side effects of existing drugs, defines a medical need for novel NNRTIs with excellent tolerability, improved activity against NNRTI-resistant viruses, and a low barrier to resistance. Within the chemical class of diarylpyrazole-[imidazolidinone]-carboxamides, AIC292 was identified as a promising novel HIV-1 NNRTI and has successfully completed single-dose clinical phase I studies. Here, we report on the antiviral activity of AIC292, evaluated in vitro against wild-type and NNRTI-resistant HIV-1 isolates and in vivo using an engineered mouse xenograft model. AIC292 inhibited wild-type HIV-1 laboratory strains at low nanomolar concentrations, was well tolerated in different cell lines, and showed excellent selectivity in a lead profiling screen. In addition, activity of AIC292 could be demonstrated against a broad panel of wild-type HIV-1 group M and group O clinical isolates. AIC292 also retained activity against viruses harboring NNRTI resistance-associated mutations (RAMs), including the most prevalent variants, K103N, Y181C, and G190A. Interestingly, viruses bearing the L100I RAM were hypersusceptible to AIC292. Two-drug combination assays showed no antagonistic interactions between AIC292 and representative marketed HIV drugs with regard to antiviral activity. Furthermore, AIC292 displayed potent antiviral in vivo efficacy in a mouse xenograft model when applied once daily. Taken together, these data show that AIC292 represents a molecule with the antiviral properties of a novel NNRTI for the treatment of HIV-1 infection.

Abstract
BACKGROUND There are limited data on etravirine (ETV) use in routine clinical practice. METHODS The reasons, efficacy and tolerability of its use are retrospectively reviewed. RESULTS Overall, 151patients started a regimen containing ETV. The main reasons for prescription were toxicity and virological failure. After a median follow-up of 16months 76.2% of the patients had an undetectable viral load. Patients with detectable HIV-RNA at baseline had a greater risk of failure (31.7% vs 18%; P=.05). CONCLUSION ETV is safe, effective and durable.

Abstract
When individualizing therapy for HIV-positive patients and for those in whom the 'preferred regimens' of the US Department of Health and Human Services HIV treatment guidelines are not appropriate, a once-daily non-nucleoside with a fixed-dose combination of two nucleosides may be considered in patients who are adherence challenged, intolerant to other regimens but with no viral resistance, or in those in whom the pill burden or actual pill size was too great to accept. Despite having a 30- to 40-h elimination half-life, etravirine was never considered for once-daily dosing during development due to an unacceptably high pill burden in phase II trials. However, a recently published study, SENSE, enrolled 157 HIV-positive patients in a multinational, randomized, placebo-controlled, double-blind trial that investigated 400 mg etravirine once daily with two nucleosides versus a comparator arm that included efavirenz and two nucleosides. The primary objective was to assess neuropsychiatric tolerability over the 48-week study period, with comparative efficacy as a secondary objective. Using the intent-to-treat time to loss of virologic response (ITT-TLOVR) analysis at 48 weeks, 76 % of patients receiving etravirine had an undetectable viral load of <50 copies/mL compared with 74 % of patients receiving efavirenz. This translates to a suppression rate difference of 1.6 % favouring etravirine (95 % CI -12.0-15.2) and met the non-inferiority criteria of a delta of -12 %. Baseline viral load was not observed to impact clinical response rates. Pharmacokinetically and clinically, studies indicate the efficacy and safety of utilizing once-daily etravirine in the treatment-naive population. While it is not appropriate for all patients, once-daily etravirine is best utilized for patients in whom caloric requirements, pill burden, pill size, potential adverse reactions, concomitant medications/drug interactions, psychosocial factors and patient preference preclude the use of a 'preferred' regimen. Etravirine dissolution in water allows for the flexibility of once-daily dosing with one fixed-dose combination tablet followed by an etravirine/water 'chaser'.

Abstract
The once-daily, single-tablet regimen of emtricitabine/rilpivirine/tenofovir disoproxil fumarate (Eviplera™ [EU]; Complera™ [US]) provides a convenient option for antiretroviral therapy in treatment-naive patients with HIV-1 infection. In well designed trials in this patient population, rilpivirine plus emtricitabine/tenofovir disoproxil fumarate was noninferior to efavirenz plus emtricitabine/tenofovir disoproxil fumarate in terms of reducing viral HIV-1 RNA level to <50 copies/mL and was generally better tolerated than efavirenz plus emtricitabine/tenofovir disoproxil fumarate.

Abstract
Etravirine (Intelence®), an oral next-generation non-nucleoside reverse transcriptase inhibitor (NNRTI), is approved for the treatment of HIV-1 infection in treatment-experienced patients. In the US, the approved use of etravirine in patients who have evidence of viral replication and harbor HIV-1 strains resistant to other antiretroviral agents has recently been expanded to include pediatric patients aged ≥ 6 to <18 years. At 24 and 48 weeks in an open-label trial, etravirine 5.2 mg/kg twice daily (maximum dosage 200 mg twice daily) plus an optimized background therapy regimen achieved complete viral response (defined as HIV-1 RNA <50 copies/mL) in approximately half of treatment-experienced children and adolescents with HIV-1 infection and evidence of viral replication, and had an acceptable tolerability profile.

Abstract
Twenty-one new 4-substituted diarylaniline compounds (DAANs) (series 13, 14, and 15) were designed, synthesized, and evaluated against wild-type and drug resistant HIV-1 viral strains. As a result, approximately a dozen new DAANs showed high potency with low nano- to subnanomolar EC(50) values ranging from 0.2 to 10 nM. The three most promising compounds 14e, 14h, and 15h exhibited high potency against wild-type and drug-resistant viral strains with EC(50) values at the subnanomolar level (0.29-0.87 nM) and were comparable to or more potent than the new NNRTI drug riplivirine (2) in the same assays. Druglike physicochemical property assessments revealed that the most active DAANs (EC(50) < 10 nM) have better aqueous solubility (>1-90 μg/mL at pH 7.4 and pH 2) and metabolic stability in vitro than 2, as well as desirable log P values (<5) and polar surface areas (PSA) (<140 Å(2)). These promising results warrant further development of this novel compound class as potential potent anti-AIDS clinical trial candidates.

Abstract
A series of N-phenylarylformamide derivatives (PAFAs) with anti-wild-type HIV-1 activity (EC(50) values) ranging from 0.3 nM to 5.1 nM and therapeutic index (TI) ranging from 10 616 to 271 000 were identified as novel non-nucleoside reverse transcriptase inhibitors. Among them, compound 13g (EC(50) = 0.30 nM, TI = 184 578), 13l (EC(50) = 0.37 nM, TI = 212 819), 13m (EC(50) = 0.32 nM, TI = 260 617) and 13r (EC(50) = 0.27 nM, TI = 271 000) displayed the highest activity against this type virus nearly as potent as lead compound GW678248. Moreover, all of them were also active to inhibit the double mutant strain A(17) (K103N + Y181C) with EC(50) values of 0.29 μM, 0.14 μM, 0.10 μM and 0.27 μM, respectively. In particular, compound 13m, which showed broad-spectrum anti-HIV activity, was also effective to inhibit the HIV-2 ROD replication within 4.37 μM concentration.

Abstract
The current optimization of 2,4-diarylaniline analogs (DAANs) on the central phenyl ring provided a series of new active DAAN derivatives 9a-9e, indicating an accessible modification approach that could improve anti-HIV potency against wild-type and resistant strains, aqueous solubility, and metabolic stability. A new compound 9e not only exhibited extremely high potency against wild-type virus (EC(50) 0.53 nM) and several resistant viral strains (EC(50) 0.36-3.9 nM), but also showed desirable aqueous solubility and metabolic stability, which were comparable or better than those of the anti-HIV-1 drug TMC278 (2). Thus, new compound 9e might be a potential drug candidate for further development of novel next-generation NNRTIs.

Abstract
On the basis of the structures and activities of our previously identified non-nucleoside reverse transcriptase inhibitors (NNRTIs), we designed and synthesized two sets of derivatives, diarylpyridines (A) and diarylanilines (B), and tested their anti-HIV-1 activity against infection by HIV-1 NL4-3 and IIIB in TZM-bl and MT-2 cells, respectively. The results showed that most compounds exhibited potent anti-HIV-1 activity with low nanomolar EC50 values, and some of them, such as 13m, 14c, and 14e, displayed high potency with subnanomolar EC50 values, which were more potent than etravirine (TMC125, 1) in the same assays. Notably, these compounds were also highly effective against infection by multi-RTI-resistant strains, suggesting a high potential to further develop these compounds as a novel class of NNRTIs with improved antiviral efficacy and resistance profile.

Abstract
Significant advances have been made in the treatment of human immunodeficiency virus (HIV) infection over the past two decades. Improved therapy has prolonged survival and improved clinical outcome for HIV-infected children and adults. Sixteen antiretroviral (ART) medications have been approved for use in pediatric HIV infection. The Department of Health and Human Services (DHHS) has issued "Guidelines for the Use of Antiretroviral Agents in Pediatric HIV Infection", which provide detailed information on currently recommended antiretroviral therapies (ART). However, consultation with an HIV specialist is recommended as the current therapy of pediatric HIV therapy is complex and rapidly evolving.
