Sustainable Global Resources of Seaweeds Volume 2

Abstract

Macroalgae commonly known as seaweeds are well-established natural resources of bioactive compounds responsible for various biological properties. There is a continuous search for new antiviral agents from natural sources, with a better activity and safety on resistant mutant strains and host cells respectively. Recently the focus has shifted towards the vast macroalgae resource and their antiviral potential; as they exhibited stronger activity than remdesivir. Their biochemical moieties are novel and distinct compared to the terrestrial plants. Some of them have shown lesser cytotoxicity. In this chapter, we aim to emphasize on their antiviral components and their mechanism of action. Studies have suggested their effectiveness against various viruses. Multiple antiviral activities from seaweeds towards the recent SARS-CoV-2 pandemic is also being discussed.
