日期:2000.9.1
Kasumigamide (1), a novel antialgal tetrapeptide containing an N-terminal alpha-hydroxy acid, was isolated from the freshwater cyanobacterium Microcystis aeruginosa (NIES-87). Its structure was elucidated by two-dimensional (1)H-(1)H and (1)H-(13)C NMR correlation experiments and confirmed by mass spectral and aminoacid analyses. The absolutestereochemistry of 1 was determined by chemical studies
