K. Harada et al., 2 CYCLIC-PEPTIDES, ANABAENOPEPTINS, A 3RD GROUP OF BIOACTIVE COMPOUNDS FROM THE CYANOBACTERIUM ANABAENA-FLOS-AQUAE NRC-525-17, Tetrahedron letters, 36(9), 1995, pp. 1511-1514
Two cyclic peptides, anabaenopeptins A (1) and B (2), were isolated as
a third group of bioactive compounds from Anabaena flos-aquae NRC 525
-17. Their structures were determined by 2D-NMR techniques and Marfey'
s method combined with LC/MS.
