Four new cyclic acyldepsipeptides (1-4), assigned the trivial names ka
iluins A-D, have been isolated from liquid cultures of a Gram-negative
bacterium (BH-107) obtained from driftwood collected at Kailua beach,
Oahu. Structure elucidation employed 2-D NMR analyses, HRFABMS, and c
hemical derivatizations. Kailuins A-D exhibited mild cytotoxicity when
tested against certain human tumor cell lines. (C) 1997, Elsevier Sci
