A joint team of Russian scientists has found that polysaccharides contained in Pacific red algae can inhibit virus infection of cells, which will help develop new drugs against virus infection

Project leader, Irina Yermak, chief researcher of the Pacific Institute of Bioorganic Chemistry, Far Eastern Branch of the Russian Academy of Sciences, Ph.

Studies have shown that carrageenan isolated from the Japanese sea red alga "Tichocarpus crinitus" has a complex structure

The antiviral effects of carrageenan and its oligosaccharides start from the lowest nanomolar concentrations and concentrations that are completely nontoxic to cells, which demonstrates their activity and safety

Experiments have shown that carrageenan and its oligosaccharides are specific for certain viral proteins and therefore have different efficacy against pathogens

Yermak concluded that low concentrations of carrageenan and its low-molecular-weight derivatives are not only nontoxic, but also have high antiviral activity, which opens up new avenues for their use as antiviral agents, especially against immunodeficiency viruses
