Objectives: Given the high need and the absence of specific antivirals for treatment of COVID-19 (the disease caused by severe acute respiratory syndrome-associated coronavirus-2 [SARS-CoV-2]), human immunodeficiency virus (HIV) protease inhibitors are being considered as therapeutic alternatives.
Methods: Prezcobix/Rezolsta is a fixed-dose combination of 800 mg of the HIV protease inhibitor darunavir (DRV) and 150 mg cobicistat, a CYP3A4 inhibitor, which is indicated in combination with other antiretroviral agents for the treatment of HIV infection. There are currently no definitive data on the safety and efficacy of DRV/cobicistat for the treatment of COVID-19. The in vitro antiviral activity of darunavir against a clinical isolate from a patient infected with SARS-CoV-2 was assessed.
Results: DRV showed no antiviral activity against SARS-CoV-2 at clinically relevant concentrations (EC > 100 μM). Remdesivir, used as a positive control, demonstrated potent antiviral activity (EC = 0.38 μM).
Conclusions: Overall, the data do not support the use of DRV for the treatment of COVID-19.

Background: Monkeypox (Mpox) is a re-emerging zoonotic disease with limited therapeutic options, necessitating the exploration of novel antiviral agents. (turmeric) is a widely used medicinal plant known for its antioxidant and anti-inflammatory properties, primarily attributed to its bioactive curcuminoids.
Aim: This study aimed to evaluate the therapeutic potential of aqueous extract (CAE) against monkeypox through phytochemical characterization, biological assays, and computational analyses.

An efficient Pd-catalyzed regioselective intramolecular aerobic oxidative dehydrocoupling of BH/CH between -carborane and arenes has been achieved with the construction of a series of five-, six- and seven-membered rings under mild reaction conditions. Control experiments indicate that B-H activation proceeds preferentially over the aryl C-H. These new polyarene-carborane conjugates have potential applications in materials as demonstrated by pyrene fused -carborane that exhibits unique dual-phase emission, intramolecular charge transfer (ICT), and aggregation-induced emission (AIE) properties.

Prenatal and intrapartum invasive tests are possible mechanisms of mother to child transmission (MTCT) of hepatitis B virus (HBV). The viral activity can affect the MTCT risk after invasive tests, but the evidence is scarce. This scoping review discussed the effects of prenatal or intrapartum invasive tests on the risk of HBV MTCT.

Background: Both oxidative stress and autoimmune responses play crucial roles in the development of vitiligo. Under oxidative stress, the apoptotic melanocytes expose self-antigens and release high mobility group box 1 (HMGB1), triggering autoimmune activation and recruiting CD8 T cells. This process further leads to the destruction of melanocytes, resulting in the lack of melanin granules.

The spreading of COVID-19 has posed a risk to global health, especially for lung cancer patients. An investigation is needed to overcome the challenges of COVID-19 pathophysiology and lung cancer disease. This study was designed to evaluate the phytoconstituents in Punica granatum peel (PGP), its anti-lung cancer activity, and in silico evaluation for antiviral potential.
