โœฆ Synopsis


Micropeptins 88-A to 88-F (1-6) have been isolated from the cyanobacterium Microcystis aeruginosa (NIES-88). Their structures were determined by two-dimensional IH-IH and IH-13C NMR correlation experiments and confirmed by mass spectral and amino acid analyses. Their absolute stereochemistries were deduced by a combination of spectral and chemical studies. Micropeptins 88-A and 88-C to 88-F inhibited chymotrypsin potently with IC50 of 0.4-10.0 lag/mE

Micropeptin 103, a chymotrypsin inhibitor, was isolated from the cultured freshwater cyanobacterium Microcystis viridis (NIES-103). So far, this type of peptide has not been reported from Microcystis viridis. Its structure was elucidated to be 1 on the basis of 2D NMRdata and chemicaldegradation. Mi
