The synthesis of 1,2-substituted benzimidazoles is reported. These novel derivatives share chemical similarities with 1-aryl-1H,3H-thiazolo[3,4-a]benzimidazoles, a class of HIV-1 NNRTIs studied widely. All compounds prepared were tested in MT-4 cells to explore their potential anti-HIV activity and were found to be less potent than 1-(2,6-difluorophenyl)-1H,3H-thiazolo[3,4-a]benzimidazole (TBZ).

Islatravir (ISL) is a novel antiretroviral that inhibits HIV-1 reverse transcriptase translocation. The M184V mutation, known to reduce ISL's viral susceptibility in vitro, could arise from prolonged exposure to nucleoside reverse transcriptase inhibitors (NRTI) (3TC). This study evaluated the predictive efficacy of ISL and identified potentially active antiretrovirals in combination among treatment-experienced patients in Cameroon, where NRTIs (3TC) have been the backbone of ART for decades now.

Highly active antiretroviral therapy has led to a significant increase in the life expectancy of people living with HIV. The trade-off is that HIV-infected patients often suffer from comorbidities that require additional treatment, increasing the risk of Drug-Drug Interactions (DDIs), the clinical relevance of which has often not been determined during registration trials of the drugs involved. Therefore, it is important to identify potential clinically relevant DDIs in order to establish the most appropriate therapeutic approaches.

Tigilanol tiglate (EBC-46) is a selective modulator of protein kinase C (PKC) isoforms that is Food and Drug Administration (FDA) approved for the treatment of mast cell tumors in canines with up to an 88% cure rate. Recently, it has been FDA approved for the treatment of soft tissue sarcomas in humans. The role of EBC-46 and, especially, its analogs in efforts to eradicate HIV, treat neurological and cardiovascular disorders, or enhance antigen density in antigen-targeted chimeric antigen receptor-T cell and chimeric antigen receptor-natural killer cell immunotherapies has not been reported.

Unlabelled: Interlinked interactions between the viral capsid (CA), nucleoporins (Nups), and the antiviral protein myxovirus resistance 2 (MX2/MXB) influence human immunodeficiency virus 1 (HIV-1) nuclear entry and the outcome of infection. Although RANBP2/NUP358 has been repeatedly identified as a critical player in HIV-1 nuclear import and MX2 activity, the mechanism by which RANBP2 facilitates HIV-1 infection is not well understood. To explore the interactions between MX2, the viral CA, and RANBP2, we utilized CRISPR-Cas9 to generate cell lines expressing RANBP2 from its endogenous locus but lacking the C-terminal cyclophilin (Cyp) homology domain and found that both HIV-1 and HIV-2 infections were reduced significantly in RANBP2 cells.
