By looking at whether existing medications could be used as a starting point for new anti-flu drugs, researchers at the University of Hertfordshire are helping to pave the way for future treatments against influenza.

The study, published in the journal Virology and carried out within the Biosciences Research Group at the University of Hertfordshire, used computer-based analysis to focus on the nuclear export protein as a drug target. The nuclear export protein facilitates the spread of the by interacting with other proteins inside cells.

From the 1,700 approved drugs tested, researchers identified an used in as a starting point for new anti-flu drugs. The findings could be used in lab-based experiments by scientists looking to create future anti-flu drugs.

Dr. Andreas Kukol, from the School of Life and Medical Sciences at the University of Hertfordshire, said: "The flu virus is constantly changing, and it adapts to evade our or any treatment aimed at stopping the virus. Therefore, new vaccinations are needed every year. To uncover the virus' hidden secrets, we investigated the nuclear export protein from 3,000 virus samples to identify constant regions, which is the part of the virus that is unlikely to change as it evolves. Against those constant regions, a large number of potential drugs were screened computationally. Our predictions can help other virologists to identify the anti-flu drugs of the future."
