1. New aureolic acid antibiotics. II. Structure determination
M Koenuma, Y Yoshimura, K Matsumoto, Y Terui J Antibiot (Tokyo). 1988 Jan;41(1):68-72. doi: 10.7164/antibiotics.41.68.
Structure determination using NMR spectroscopy of new aureolic acid analogues, demethylchromomycins A2 and A3 and demethylolivomycins A and B produced by Streptomyces aburaviensis PA-39856, is described.
2. NMR studies of chromomycins, olivomycins, and their derivatives
Y Yoshimura, M Koenuma, K Matsumoto, K Tori, Y Terui J Antibiot (Tokyo). 1988 Jan;41(1):53-67. doi: 10.7164/antibiotics.41.53.
Detailed studies on the 13C and 1H NMR spectra of chromomycins A2 and A3, olivomycins A and B, and their derivatives clarified the assignment of many signals which had been unassigned or erroneously reported in the literatures. The revised assignments for chromomycin A3 and olivomycin A include the assignment of a key 13C signal used to discuss the saccharide linkage in question. Structure analyses based on the revised assignments support the alpha,1----3-bond between components of the disaccharide moiety in the molecules. Some general information useful for structure analysis of saccharides is also reported.
