Title: Novel caprolactones from a marine streptomycete.

Authors: Stritzke K, Schulz S, Laatsch H, Helmke E, Beil W.

Abstract: Two new caprolactones, (R)-10-methyl-6-undecanolide (1) and (6R,10S)-10-methyl-6-dodecanolide (2), were identified in the lipid extract of a marine streptomycete (isolate B6007). Their structures were proposed on the basis of GC-MS experiments and proved by synthesis. The absolute configuration of the compounds was established by comparison of the natural and synthetic stereoisomers using chiral gas chromatography. These caprolactones show a moderate phytotoxicity and a promising activity against cancer cells with concomitant low general cytotoxicity.
