Isolation of new derivatives of the 20-membered macrodiolide bispolide from Kitasatospora sp. MG372-hF19


New three macrocyclic diolides, named bispolides C-E (13), were isolated from a fermentation broth of the actinomycete strain MG372-hF19, which produces an indole glycoside and leptomycins as we reported previously. The absolute structures of compounds 13 were elucidated by NMR and X-ray crystallography. Compounds 13 diverge from the known nine bispolides in their different alkylation patterns on the 20-membered macrocyclic diolide skeleton and the side chain in their planar structures. Furthermore, compounds 13 exhibited antibacterial activity against methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococci and cytotoxic activity against human cancer cell lines. Among them, compound 3 has the most potent biological activities against bacteria and tumor cells. Additionally, using a membrane-potential-sensitive fluorescence probe, we found that compounds 13 and elaiophylin have a similar effect on membrane potential in A549 human lung cancer cells.
