Antibacterial and antiviral metabolites from cyanobacteria: Their application and their impact on human health

• Cyanobacterial antiviral and antibacterial metabolites cover a broad chemical space. Some natural product classes are selective for either virus or bacteria. Most have been isolated from Nostoc species. Cyanobacteria promising hosts heterologous expression. Bacterial viral infections pose direct threat to human health due the increase of drug-resistant novel pathogenic strains. Natural products represent prolific source bioactive metabolites, which exploited their therapeutic effects. In particular, cyanobacteria were identified as important producers secondary possessing activities, among others. A meta-analysis indicated that some target bacteria viruses exclusively. This result also applied cyanobacterial species produce only compounds. Furthermore, host bio-production ability perform photosynthesis low-cost production requirements. review highlights compounds isol biotechnological application these organisms .
