Recent progresses in marine microbial-derived antiviral natural products

Viruses have always been a class of pathogenicmicroorganisms that threaten the health and safety of humanlife worldwide. However, for a long time, the treatment ofviral infections has been slow to develop, and only a fewantiviral drugs have been using clinically. Compared withthese from terrestrial environments, marine-derived microorganismscan produce active substances with more novelstructures and unique functions. From 2015 to 2019, 89antiviral compounds of 8 structural classes have been isolatedfrom marine microorganisms, of which 35 exhibit anti-H1N1 activity. This review surveys systematically marinemicrobial-derived natural products with antiviral activityand illustrates the impact of these compounds on antiviraldrug discovery research.

Chemical investigation of the fermentation broth of a Soft Coral-Derived fungus Pestalotiopsis sp., led to the isolation of a new phthalide derivative, pestalotiolide A (1), three known analogues (2, 3 and 4), along with 5'-O-acetyl uridine (5) first isolated as a natural product. The structure of the new compound (1) was established by comprehensive spectroscopic analysis and chemical methods. Compounds 1 - 4 possessed varying degrees of antiviral activities, which was reported for the first time. Compared to the positive control ribavirin (IC50 = 418.0 μM), pestalotiolide A (1) exhibited significant anti-EV71 activity in vitro, with an IC50 value of 27.7 mM. Furthermore, the preliminary structure-activity relationship of antiviral activities was also discussed.
