dAburatubolactam A ((1) under bar), isolated from the cultured broth o
f a Streptomyces sp., SCRC-A20, separated from a mollusk, potently inh
ibited superoxide anion generation. The structure of aburatubolactam A
was determined by X-ray crystallographic analysis and the complete as
signment of the resonances in the H-1-NMR spectrum was achieved.
