In an attempt to identify potential new agents that are active against HIV-1 IN, a series of novel coumarin-3-carbohydrazide derivatives were designed and synthesised. The toxicity profiles of these compounds showed that they were non-toxic to human cells and they exhibited promising anti-HIV-1 IN activities with IC50 values in nM range. Also, an accompanying molecular modeling study showed that the compounds bind to the active pocket of the enzyme.

These updated guidelines from the Infectious Diseases Community of Practice of the American Society of Transplantation review the management of transplantation in HIV infected individuals. Transplantation has become the standard of care for patients with HIV and end stage kidney or liver disease. Although less data exist for thoracic organ and pancreas transplantation, it is likely that transplantation is also safe and effective for these recipients as well. Despite what is typically a transient decline in CD4+ T lymphocytes, HIV remains well-controlled and infection risks are similar to those of HIV uninfected transplant recipients...

Latently infected CD4 lymphocytes preclude cure of HIV infection, even with the most effective antiretroviral therapy. The replication competent latent HIV reservoir has been quantified with the terminal dilution quantitative viral outgrowth assay, which induces virus propagation in CD4+ T cell culture supernatants following cellular activation. Efforts to improve the sensitivity of this inefficient assay have introduced more sensitive p24 ELISA and RNA PCR based endpoints, but these more sensitive endpoints have raised the question whether they are measuring induced replication competent or defective virions...

Objectives: We estimated the prevalence of transmitted-drug-resistance-associated mutations (TDRAMs) in antiretroviral-naive chronically HIV-1-infected patients. Patients and methods: TDRAMs were sought in samples from 660 diagnosed HIV-1-infected individuals in 2015/2016 in 33 HIV clinical centres. Weighted analyses, considering the number of patients followed in each centre, were used to derive representative estimates of the percentage of individuals with TDRAMs...

Background: HIV-2 is a neglected virus despite estimates of 1-2 million people being infected worldwide. The virus is naturally resistant to some antiretrovirals used to treat HIV-1 and therapeutic options are limited for patients with HIV-2. Methods: In this retrospective observational study, we analysed all HIV-2-infected individuals treated with integrase strand transfer inhibitors (INSTIs) recorded in the Spanish HIV-2 cohort. Demographics, treatment modalities, laboratory values, quantitative HIV-2 RNA and CD4 counts as well as drug resistance were analysed...

BACKGROUND: We compared time to treatment change (TC), viral suppression (VS) and change in CD4+ T-cell counts of first-line antiretroviral regimens (ART). METHODS: We analyzed HIV treatment-naïve adults from the Cohort of the Spanish HIV/AIDS Research Network (CoRIS) initiating the most commonly used ART regimens from September 2014 to November 2015. We used proportional hazards models on the sub-distribution hazard to estimate sub-distribution hazard ratios (sHR) for time to TC, logistic regression to estimate odds ratios (ORs) for VS (viral load<50 copies/ml), and linear regression to assess mean differences in CD4 changes from ART initiation...

The failure of the Integrase Strand Transfer Inhibitors (INSTIs) due to the mutations occurring at catalytic site of HIV integrase (IN) has led to the design of allosteric integrase inhibitors (ALLINIs). Lens epithelium derived growth factor (LEDGF/p75) is the host cellular cofactor helps chaining IN to the chromatin. The protein-protein interactions (PPIs) were observed at allosteric site (LEDGF/p75 binding domain) between LEDGF/p75 of host cell and IN of virus. In the recent years, many small molecules such as CX04328, CHIBA-3053 and CHI-104 are reported as LEDGF/p75-IN interaction inhibitors (LEDGINs)...

Accelerated neurological disorders are increasingly prominent among the HIV-infected population and are likely driven by the toxicity from long-term use of antiretroviral drugs. We explored potential side effects of antiretroviral drugs in HIV-infected primary human astrocytes and whether opioid co-exposure exacerbates the response. HIV-infected human astrocytes were exposed to the reverse transcriptase inhibitor, emtricitabine, alone or in combination with two protease inhibitors ritonavir and atazanavir (ERA) with and without morphine co-exposure...

Development of a highly accurate prediction model for protein-ligand inhibition has been a major challenge in drug discovery. Herein we describe a novel predictive model for the inhibition of HIV-1 integrase (IN)-LEDGF/p75 protein-protein interaction. The model was constructed using energy parameters approximated from molecular dynamics (MD) simulations and molecular mechanics Poisson-Boltzmann surface area (MM-PBSA) calculations. Chemometric analysis using partial least squares (PLS) regression revealed that solvent accessible surface area energy (ΔGSASA ) is the major determinant parameter contributing greatly to the prediction accuracy...

The pharmacophore of active site inhibitors of human immunodeficiency virus (HIV) reverse transcriptase (RT)-associated RNase H typically entails a flexible linker connecting the chelating core and the hydrophobic aromatics. We report herein that novel 3-hydroxypyrimidine-2,4-dione (HPD) subtypes with a nonflexible C-6 carbonyl linkage exhibited potent and selective biochemical inhibitory profiles with strong RNase H inhibition at low nM, weak to moderate integrase strand transfer (INST) inhibition at low μM, and no to marginal RT polymerase (pol) inhibition up to 10 μM...

In spite of remarkable reduction in the number of children born with HIV due to antiretroviral therapy, concerns remain on the short- and long-term effects of antiretroviral drugs at the feto-placental unit. Cardio- and skeletal myopathies have been reported in children exposed to antiretroviral drugs prenatally. These conditions have also been described in perturbed placental transfer of l-carnitine, an essential co-factor in fatty acid oxidation. Due to limited fetal and placental synthesis, carnitine supply is maintained through the placental carnitine uptake from maternal blood by the organic cation/carnitine transporters OCTN1 and OCTN2 (SLC22A4 and SLC22A5, respectively)...

Current antiretroviral therapy is more effective and simpler than in previous times due to the development of new drugs with improved pharmacokinetic and pharmacodynamic profiles and the advent of single pill regimens with low toxicity that facilitate long-term adherence. The recent approval of the novel potent integrase strand-transfer inhibitor bictegravir (BIC) co-formulated with emtricitabine (FTC) and tenofovir alafenamide (TAF) in a fixed daily dose pill, B/F/TAF, adds to the list of single-tablet regimens available to treat HIV infection...

HIV-1 integrase, a member of a polynucleotidyl transferases superfamily, catalyze the insertion of the viral DNA into the genome of host cells. It has emerged as a potential target for developing anti-HIV agents. In last two decades, number of integrase inhibitors has been developed as potential anti-HIV therapeutics. Several integrase inhibitors have reached later stages of clinical trials including S-1360, L870,810, L870,812 and BMS-707035. Into the bargain, Raltegravir, Elvitegravir and Dolutegravir have been approved by FDA as anti-HIV agents...
