Cyanometabolites: molecules with immense antiviral potential

Area of Science:

• Biochemistry
• Microbiology
• Pharmacology

Background:

• Cyanometabolites, derived from cyanobacteria, encompass a diverse range of compounds including peptides, lectins, and alkaloids.
• While some cyanometabolites can be toxic, many possess significant health benefits, notably antiviral activities against pathogens like HIV, Ebola, and influenza.
• Specific cyanometabolites, such as lectins (e.g., cyanovirin-N) and peptides (e.g., microginin FR1), demonstrate unique antiviral mechanisms and therapeutic potential, including for COVID-19.

Purpose of the Study:

• To review the antiviral properties of cyanobacteria metabolites from the late 1990s to the present.
• To highlight the significance of cyanometabolites in combating viral diseases, with a focus on SARS-CoV-2.
• To emphasize the medicinal potential of cyanobacteria for future pandemic preparedness.

Main Methods:

• Literature review of scientific publications on cyanometabolites and their antiviral activities.
• Analysis of studies detailing the mechanisms of action of specific cyanometabolites against various viruses.
• Synthesis of information regarding the therapeutic applications and future potential of cyanobacteria-derived compounds.

Main Results:

• Cyanometabolites, including lectins and peptides, possess broad-spectrum antiviral activities against numerous human pathogens.
• Microginin FR1 shows potential for treating coronavirus disease 2019 (COVID-19) by inhibiting angiotensin-converting enzyme (ACE).
• Cyanometabolites, particularly those targeting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), have been underexplored but show significant promise.

Conclusions:

• Cyanobacteria are a rich source of bioactive compounds with significant antiviral potential.
• Cyanometabolites offer promising therapeutic strategies against viral infections and could be valuable in combating future pandemics.
• Further research into cyanometabolites could lead to novel மருந்துகள் and dietary supplements for public health.
