The development of dual inhibitors of HIV-1 protease and reverse transcriptase is an attractive strategy for multi-target therapeutic of AIDS, which may be privileged in delaying the occurrence of drug resistance. We herein designed a novel kind of dual inhibitors with benzofuran or indole cores. Biological results showed that a number of inhibitors displayed significant activity against both HIV-1 protease and reverse transcriptase. Among which, inhibitor 10f exhibited a good correlation with an approximate ratio of 1: 2 between the two enzymes. Furthermore, the dual inhibitors illustrated similar potency against both the wild-type virus and drug-resistant mutant. In addition, the molecular dynamic simulation studies verified the dual actions of such inhibitors.

Current anti-HIV drugs have significantly improved the prognosis of HIV infected patients so much so that it is now considered a chronic disease, and adherence to medications keeps non-detectable amounts of the virus in the body. However, HIV is still able to generate drug resistance substitutions. Protease inhibitors (PIs) in combination with other classes of anti-HIV drugs constitute an important part of the anti-HIV drug regimen.

Despite significant advancements with combination anti-retroviral agents, eradicating human immunodeficiency virus (HIV) remains a challenge due to adverse effects, adherence issues, and emerging viral resistance to existing therapies. This underscores the urgent need for safer, more effective drugs to combat resistant strains and advance acquired immunodeficiency syndrome (AIDS) therapeutics. Eight triterpene esters (1-8) were identified from Uncaria rhynchophylla hooks.

Highly mutated HIV-1 protease (PR) compromises the efficacy of lopinavir (LPV) and darunavir (DRV) used to formulate salvage regimens in HIV/AIDS management. Here, we report the kinetics of inhibition of lopinavir (LPV) and darunavir (DRV) on highly mutated South African HIV-1 subtype C PR obtained from clinical isolates. The wild-type and mutant South African HIV-1 subtype C PR were cloned and purified.

Cervical cancer cases continue to rise despite all the advanced screening and preventative measures put in place, which include human papillomavirus (HPV) vaccination. These soaring numbers can be attributed to the lack of effective anticancer drugs against cervical cancer; thus, repurposing the human immunodeficiency virus protease inhibitors is an attractive innovation. Therefore, this work was aimed at evaluating the potential anticancer activities of HIV-PIs against cervical cancer cells.
