Many cases of human immunodeficiency virus (HIV)-1 infection can be effectively treated with existing drugs, but they can lose efficacy over time because of the emergence of resistance. In an effort to generate next-generation drugs, Chinese researchers at the Chinese Academy of Medical Sciences & Peking Union Medical College and other institutions synthesized a series of peptidomimetics against the viral protease, in which they extended the therapeutically effective hydroxyethyl sulfonamide scaffold using an amino acid linker. They reasoned that the linker could allow the drug to make additional contacts with the protease.
2025 has been the most challenging year in the efforts to fight HIV since at least the advent of antiretroviral therapy. In a report on “Overcoming disruption, transforming the AIDS response,” released last week ahead of World AIDS Day on Dec. 1, the Joint United Nations Program on HIV/AIDS (UNAIDS) described “a global system in shock” by sharply reduced funding from the U.S. and other wealthy nations. Scientifically, for now, progress is ongoing.

In vaccine development, one might think that targeting multiple epitopes increases the likelihood of improving outcomes. However, when several immunogens are administered together, the immune system does not always generate antibodies against all of them. Two parallel studies have overcome this challenge by using multiple simultaneous immunogens against HIV, effectively triggering various types of broadly neutralizing antibody (bnAb) precursors in two different preclinical animal models.
Merck Sharp & Dohme LLC (MSD) has synthesized new N-oxide derivative targeted activator of cell kill (TACK) compounds acting as Gag polyprotein (HIV-1)/protein Pol dimerization inducers reported to be useful for the treatment of HIV infection.
Globally, over half of people living with HIV are women. But in clinical cure trials, they make up only about 20% of participants. And that gender imbalance is causing researchers to miss out on ways to improve cure strategies. Because women’s immune systems appear to be better at controlling HIV infection in a way that silences the reservoir – the provirus integrated into host cells in infected persons.

The National Institute of Allergy and Infectious Diseases (NIAID) has awarded a 5-year $20.8 million grant to a multi-institutional team led by Weill Cornell Medicine investigators for advanced preclinical development of a promising experimental HIV vaccine.
Nucleoside reverse transcriptase translocation inhibitors (NRTTIs) are a novel class of antiretroviral agents that inhibit HIV replication by targeting the viral reverse transcriptase enzyme and specifically blocking its translocation step during DNA synthesis, a critical process in the viral replication cycle.
