Microviridin
Microviridins are a class of serine protease inhibitors produced by various genera of cyanobacteria. Microviridins are characterized by tricyclic depsipeptide structure and are members of the RiPP family of natural products.
The first microviridin was isolated from Microcystis viridis (NIES-102) and its structure was reported in 1990.[1]
The known microviridins include microviridins A-L.
Toxicity
Microviridin J has been found to disrupt molting in the invertebrate Daphnia pulicaria, probably as a result of its protease inhibitory effects [2]
