Molecules, Vol. 25, Pages 4075: Preparation and Characterization of Two Immunogens and Production of Polyclonal Antibody with High Affinity and Specificity for Darunavir
In this study, two new and different immunogens were prepared and characterized. These immunogens were the DRV conjugates with keyhole limpet hemocyanin (KLH) protein. The first immunogen (DRV-KLH) was prepared by zero-length direct linking of DRV via its aromatic amino group with the tyrosine amino acid residues of KLH by diazotization/coupling reaction. The second immunogen (G-DRV-KLH) was prepared by conjugation of the N-glutaryl derivative of DRV (G-DRV) with KLH. The 5-carbon atoms-spacing G-DRV hapten was synthesized by reaction of DRV via its aromatic amino group with glutaric anhydride. The reaction was monitored b...

Drug repurposing approach to fight COVID-19.
Abstract Currently, there are no treatment options available for the deadly contagious disease, coronavirus disease 2019 (COVID-19). Drug repurposing is a process of identifying new uses for approved or investigational drugs and it is considered as a very effective strategy for drug discovery as it involves less time and cost to find a therapeutic agent in comparison to the de novo drug discovery process. The present review will focus on the repurposing efficacy of the currently used drugs against COVID-19 and their mechanisms of action, pharmacokinetics, dosing, safety, and their future perspective. Relevant arti...

Analysis of type I IFN response and T cell activation in severe COVID-19/HIV-1 coinfection: A case report
Rationale: Complex immune dysregulation in interferon (IFN) and T cell response has been observed in human immunodeficiency virus (HIV-1)-infected patients as well as in coronavirus disease-2019 (COVID-19) patients. However, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)/HIV-1 coinfection has been described in only few cases worldwide and no data are available on immunological outcomes in HIV-1-patients infected with SARS-CoV-2. Hence, this study aims to compare type I IFN response and T cell activation levels between a SARS-CoV-2/HIV-1-coinfected female patient and age-matched HIV-1-positive or uninfected ...

Anti-Inflammatory Properties of Drugs Used to Control COVID-19 and their Effects on the Renin-Angiotensin System and Angiotensin-Converting Enzyme-2.
Authors: Gilzad-Kohan H, Jamali F Abstract COVID-19 infection is associated with systemic inflammation, and sometimes hyperinflammatory responses with cytokine storm. This plays a major role in COVID-19 severity and poor disease prognosis, even death. Higher levels of inflammatory hallmarks including C-reactive protein, ferritin, D-dimers, and cytokines such as interleukin (IL) -6, IL-10 and tumor necrosis factor- α (TNF-α) have been reported. Many anti-viral drugs have been tried, but none were proven fully effective. Supportive care and management of the complications that are caused mainly by inflamm...

Application of Physiologically ‐based Pharmacokinetic Modeling to Predict Gastric pH‐dependent Drug‐drug Interactions for Weak Base Drugs
AbstractWeak base drugs (WBDs) are susceptible to drug ‐drug interactions (DDIs) when co‐administered with gastric acid reducing agents (ARAs). We developed PBPK models to evaluate the potential of such pH‐dependent DDIs for 4 WBDs, i.e., tapentadol, darunavir, erlotinib, and saxagliptin. The PBPK models of these drugs were first optimized using P K data following oral administration without ARAs, which were then verified with data from additional PK studies in the presence and absence of food. The models were subsequently utilized to predict the extent of DDIs with ARA co‐administration. Sensitivity analysis was c...

Two treatment strategies for management of Neurosymptomatic cerebrospinal fluid HIV escape in Pune, India
Symptomatic cerebrospinal fluid (CSF) viral escape (sCVE) is reported in people with HIV, who are on ritonavir-boosted protease inhibitor (PI/r) containing antiretroviral therapy (ART). Management of sCVE includes performing genotypic HIV-1 resistance testing (GRT) on CSF and plasma HIV and changing ART accordingly. Neither GRT nor newer drugs (Dolutegravir and Darunavir/ritonavir) are routinely available in India. As a result, management of sCVE includes 2 modalities: a) ART intensification by adding drugs that reach therapeutic concentrations in CSF, like Zidovudine, to existing ART or b) Changing to a regimen containing...

Aging does not impact drug--drug interaction magnitudes with antiretrovirals
The risk of drug–drug interactions (DDIs) is elevated in aging people living with HIV (PLWH) because of highly prevalent age-related comorbidities leading to more comedications. To investigate the impact of aging on DDI magnitudes between comedications (amlodipine, atorvastatin, rosuvastatin) and boosted darunavir, we conducted a clinical trial in aging PLWH aged at least 55 years. DDI magnitudes were comparable with those reported in young individuals supporting that the clinical management of DDIs in aging PLWH can be similar. (Source: AIDS)

The Molecular Docking, Synthesis and anti-HIV-1 protease Activity of Novel Chalcones.
CONCLUSION: It is difficult to provide general principles of inhibitor design. Structural properties of the compounds are not the only consideration; ease of chemical synthesis, low molecular weight, bioavailability, and stability are also of crucial importance. Compared to commercial products the main advantage of compound C1 is ease of chemical synthesis and low molecular weight. Furthermore, compound C1 has a structure that is different to peptidomimetics, which could contribute to its stability and bioavailability.

Pharmacokinetic profiles of boosted darunavir, dolutegravir and lamivudine in aging people living with HIV
Objectives: The pharmacokinetics of antiretroviral drugs may differ in elderly people living with HIV (PLWH) because of age-related physiological changes. We aimed to assess the pharmacokinetics of several antiretroviral drugs in aging PLWH enrolled in the Swiss HIV Cohort (SHCS). Design: Full pharmacokinetic profiling nested in a multicenter, observational, prospective cohort study. Additional collection of single point pharmacokinetic data during SHCS follow-up visits (unselected PLWH). Methods: PLWH were eligible for the full pharmacokinetics investigation if they were over the age of 55 years, on a stable boost...

Weight gain in people living with HIV switched to dual therapy: changes in body fat mass
Changes in weight and body composition were assessed in long-term suppressed HIV-infected patients switching to dolutegravir/rilpivirine (n = 37), and compared with similar patients switching to darunavir/lamivudine (n = 17). At month 12, weight significantly increased with dolutegravir/rilpivirine (1.8 kg, IQR −1.2 to 4.1; 2.5%; P = 0.03). A follow-up DXA (median, 16 months) showed similar increases in trunk (7.8%), arms (5.6%), and legs (6.2%) fat mass, without changes in lean mass. Despite lower weight gain (0.70 kg, IQR −0.8 to 4.0, P = 0.28), fat mass increase was similar in the darunav...

Protease Inhibitors, Saquinavir and Darunavir, Inhibit Oligodendrocyte Maturation: Implications for Lysosomal Stress
AbstractDespite the introduction of antiretroviral (ARV) therapy (ART), approximately 30 –50% of people living with human immunodeficiency virus-1 (HIV-1) will develop a spectrum of measurable neurocognitive dysfunction, collectively called HIV-associated neurocognitive disorder (HAND). While the clinical manifestations of HAND have changed with the advent of ART, certain pathological features have endured, including white matter alterations and dysfunction. The persistence of white matter alterations in the post-ART era suggests that ARV drugs themselves may contribute to HAND pathology. Our group has previously dem...
