A team of scientists has developed a new compound that can effectively target and kill drug-resistant HIV. The compound, called IC-2i, was created by combining parts of previously studied HIV inhibitors. Researchers used a powerful tool called microfocus crystallography to understand how the compound works.
Scientists from around the world have been working together to find new ways to treat HIV. Despite major advances in treatment, people living with HIV still need to take medication for life because the virus can't be completely eliminated. A team of researchers has now developed a new compound called IC-2i that shows promise in treating drug-resistant HIV.
The scientists combined parts of previously studied HIV inhibitors to create a smaller, more stable compound that targets a specific region of the HIV capsid, or protein shell. They used a powerful tool called microfocus crystallography (MX2) at the Australian Synchrotron to understand how IC-2i works.
Microfocus crystallography is a technique that allows researchers to see the structure of biological molecules at an atomic level. By using MX2, the team was able to determine how IC-2i binds to the HIV capsid and what interactions help it work effectively. This information can be used to design new HIV medicines that are more effective against resistant strains.
The World Health Organization estimates that around 39 million people were living with HIV worldwide at the end of 2022, with 1.3 million new infections and 630,000 deaths reported that year. While modern combination antiretroviral therapy can control HIV effectively, it cannot eliminate the virus completely because it can hide in long-lived reservoirs within the body.
Why It Matters
This discovery is important for people living with HIV in India who may have to take medication for life. If IC-2i becomes a viable treatment option, it could provide hope for those struggling with drug-resistant strains of the virus.
