Nosokomycins, new antibiotics discovered in an in vivo-mimic infection model using silkworm larvae. II: Structure elucidation
Abstract
The structures of nosokomycins A, B, C and D, new anti-methicillin-resistant Staphylococcus aureus antibiotics produced by Streptomyces sp. K04-0144, were elucidated by spectroscopic studies including various NMR experiments. Nosokomycins A, B, C and D are new members of the moenomycin family consisting of an oligosaccharide moiety, a 2,3-dihydroxypropionic acid and an unusual sesterterpenoid moiety. All nosokomycins lack the cyclopentenone moiety in the oligosaccharide moiety of moenomycin A.
