New Light-Driven Method Creates Antiviral Compounds in Weeks

Topic: Biology

Scientists at Simon Fraser University have developed a new method to create large libraries of antiviral compounds quickly. This could help find treatments for viral outbreaks like COVID-19.

Researchers at Simon Fraser University have found a way to speed up the process of discovering new antiviral drugs. They created a light-driven chemistry method that can produce libraries of nucleoside analogs (NAs) in just weeks, instead of months or years.

A nucleoside analog is a compound that mimics the building blocks of DNA and RNA. These compounds are used to treat cancer and viral infections like HIV and hepatitis.

The new method uses a single, scalable building block that can be produced in large quantities. A light-driven reaction attaches different nucleobases to this core structure, quickly generating a library of more than 70 NAs.

To test the approach, the researchers screened the library against HIV. Three compounds showed activity comparable to approved HIV therapies.

This breakthrough could significantly reduce the time and resources needed for early-stage drug discovery. It could also help find treatments for viral outbreaks like COVID-19, Ebola, or hantavirus.

Why It Matters

Viral outbreaks can be devastating, especially in India where healthcare systems are often overwhelmed. This new method could provide a faster way to develop antiviral drugs, saving lives and reducing the impact of future outbreaks.
