The chemical structures of 1每 4 were established by NMR, mass, UV, and IR spectroscopy as well as the modified Mosher*s method. Separacenes A每B ( 1每 2), which share an identical planar structure but possess different relative configurations, bear tetraene units flanked by two diol moieties, whereas the stereoisomeric separacenes C每D ( 3每 4) possess a triene moiety between two diol substructures. Separacenes A每D each contain a terminal olefinic methylene. Separacene A displayed inhibitory activity against Candida albicans isocitrate lyase and weak cytotoxicity against both the colon carcinoma cell line HCT-116 and the lung cancer cell line A549. %K marine actinomycete %K polyene polyol %K cytotoxicity %K isocitrate lyase %U http://www.mdpi.com/1660-3397/11/8/2882
