The Antiviral Potential of Algal Lectins

Abstract

Algae have emerged as fascinating subjects of study due to their vast potential as sources of valuable metabolites with diverse biotechnological applications, including their use as fertilizers, feed, food, and even pharmaceutical precursors. Among the numerous compounds found in algae, lectins have garnered special attention for their unique structures and carbohydrate specificities, distinguishing them from lectins derived from other sources. Here, a comprehensive overview of the latest scientific and technological advancements in the realm of algal lectins with a particular focus on their antiviral properties is provided. These lectins have displayed remarkable effectiveness against a wide range of viruses, thereby holding great promise for various antiviral applications. It is worth noting that several alga species have already been successfully commercialized for their antiviral potential. However, the discovery of a diverse array of lectins with potent antiviral capabilities suggests that the field holds immense untapped potential for further expansion. In conclusion, algae stand as a valuable and versatile resource, and their lectins offer an exciting avenue for developing novel antiviral agents, which may lead to the development of cutting-edge antiviral therapies.

“…However, in comparison, there are only limited studies on algal haemagglutinins, in spite of the availability of large number of species and amount of marine macroalgae, as compared to higher plants. In particular, lectins are proteins of nonimmune origin which bind specifically and reversibly to carbohydrates" [1,2]. "Algae are the most diverse organisms in the plant kingdom.…”

“…Microalgae have for long been used with therapeutic purposes; their systematic screening for biologically active principles began in the 1950s. The increasing interest in marine natural products has led to the discovery of new biologically active compounds and marine algae have been subjected to increasing study for this purpose" [1].…”
