Identifying virus killers in ancient medicinal plants

27.04.2020

Many organisms have to defend themselves against predators, diseases or pests. Their metabolic products constitute a chemical arsenal that has been used for medical purposes since time immemorial. Using state-of-the-art methods, a team led by Judith Rollinger is screening traditional knowledge in order to identify new active substances against lung infections caused by influenza, coronavirus or pneumococci.

Viral and bacterial infections have plagued human beings since time began. Even if they were not able to recognize the tiny pathogens, our ancestors used to relieve symptoms such as a cough, fever or respiratory problems with natural remedies. In her search for potent antiviral agents pharmacist Judith Rollinger, head of the “Phytochemistry & Biodiscovery” research group at the University of Vienna, is tapping into the powers of nature − “the world’s best chemist” − as she points out. “We use the traditional knowledge handed down over several generations as a treasure trove of empirical experience that helps us in the pre-selection of potential suppliers of active ingredients.” One survival strategy of plants and other organisms is to use their own metabolic products to ward off pests, predators and diseases. In the search for new drugs, it is necessary to harness this chemical arsenal in a targeted manner, explains Rollinger. [more]
