Unlocking nature's hidden treasures: Actinomycetota's arsenal of potent antiviral compounds against human viral infections.

The global emergence of infectious diseases, including COVID-19, Mpox, MERS, Ebola, dengue, Zika, and avian influenza, alongside the escalation of antimicrobial resistance, has made the discovery of novel antiviral agents an urgent priority. Actinomycetota, a diverse group of microorganisms known for their medicinal properties and antibiotic production, stand out as a promising source of antiviral compounds. Since the 20th century, studies on the antiviral potential of Actinomycetota-derived secondary metabolites have shown efficacy against various human viruses, such as influenza viruses (IVs), human coronaviruses (hCoVs), respiratory syncytial virus (RSV), human immunodeficiency virus (HIV), herpes simplex virus (HSV), mosquito-borne viruses such as Zika virusZIKV), dengue virus (DENV), West Nile virus (WNV), Chikungunya virus (CHIKV)), and monkeypox virus (MPXV). This review provides a comprehensive summary of key findings from the literature, emphasizing the theurapeutic potential of these compounds and the importance of further research to elucidate their mechanisms of action and enhance their production. Unlocking the antiviral arsenal of Actinomycetota may pave the way for the development of novel and effective antiviral therapies to combat human viral diseases.
