Zelkovamycin, a new cyclic peptide antibiotic from Streptomyces sp. K96-0670. II. Structure elucidation

J Antibiot (Tokyo). 1999 Jan;52(1):34-9. doi: 10.7164/antibiotics.52.34.

Abstract

The structure of antibiotic zelkovamycin was elucidated as a cyclic peptide comprising glycyl, 2-aminobutanoyl, 2-amino-2-butenoyl, N-methyl glycyl, alanyl, 1,3-thiazoyl, 7-methoxytryptophanyl and 2-methyldehydrothreonyl residues. The sequence of the amino acids was established by spectroscopic studies including 1H-1H COSY, 13C-1H COSY, 13C-1H HMQC, 13C-1H HMBC, 15N-1H HMQC and 15N-1H HMBC NMR experiments.
