Russian and international scientists announce a new HIV treatment approach
Researchers from Russia’s Federal Biotechnology Research Center and the Federal Research Center for Biotechnology, along with colleagues from the United States and Italy, have developed a new type of agent aimed at combating human immunodeficiency virus (HIV). This development was reported by the corresponding Russian scientific institution.
For many years, the medical consensus held that curing HIV outright was not possible. The standard goal has been to suppress the virus and keep it in a chronic, controlled state, thereby preventing AIDS. Patients often rely on antiretroviral therapy, a lifelong treatment that can be expensive and may require changes if the virus develops resistance to a given drug.
The collaborative team introduced a new class of compounds, named N-phenyl-1-(phenylsulfonyl)-1H-1,2,4-triazole-3-amines. According to the researchers, these compounds work by inhibiting the HIV reverse transcriptase enzyme, a key driver of viral replication. Importantly, the scientists claim that the molecule can cross the blood-brain barrier and reach the brain, where it may suppress the virus within neurons. In this context, the experimental substance is reported to be non-toxic to neuronal cells, offering potential for addressing viral reservoirs in the nervous system.
Reverse transcriptase enables certain viruses to convert their RNA into DNA inside a host cell, turning infected cells into factories that produce new virus particles. By blocking this enzyme, the new compounds could interfere with the replication cycle of HIV, Hepatitis B, and other RNA viruses, according to one of the study authors, Vadim Makarov.
The researchers emphasize that their findings could lay the groundwork for a new generation of anti-HIV medicines that might reduce the virus load more effectively and potentially contribute to long-term remission for some patients. The work highlights the ongoing global effort to develop therapies with broader action in the body, including the brain, while maintaining safety for neural tissue.
These results are preliminary and require further validation in clinical studies to assess efficacy, safety, and potential long-term benefits. The international collaboration demonstrates how cross-border scientific partnerships can accelerate the search for innovative strategies against HIV, with the aim of improving outcomes for people living with the virus.
