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.
The object of the present invention is to provide a pharmaceutical composition for treatment of hepato·biliary disease reduced in side effect such as diarrhea, which comprises 16,16-difluoro-15-keto-PGs having at least one methyl group or ethyl group on the carbon atom at the 17- or 18-position or adjacent to the terminal methyl group of ω-chain as an essential component.
