Rocaglamides from mahogany plants raise hope for the development of an antiviral drug.
The hepatitis E virus (HEV) is widespread and so far, there is no effective drug. In the search for this, the so-called rocaglamides have come into focus: plant substances that can inhibit the multiplication of viruses. Researchers from the Molecular and Medical Virology Department at the Ruhr University Bochum (RUB) have examined a library of chemically modified rocaglamides for their antiviral effects, which a team from Boston has created. A group of active substances that has a so-called amidino group stood out. It particularly effectively inhibited virus multiplication. The team around Dimas F. Praditya, Mara Klöhn and Prof. Dr. Eike Steinmann reports in the journal Antiviral Research.
Plant substances inhibit the multiplication of cancer cells and viruses
Rocaglamides are a group of plant substances that are produced by various mahogany plants. It is known that they have an inhibitory effect on the multiplication of some cancer cells. It was not until 2008 that findings on their antiviral effects against RNA viruses were published for the first time: for example, they can inhibit the multiplication of Ebolaviruses, HEV, zikaviruses or Sars-Cov-2.
