Mollicellins O⁻R, Four New Depsidones Isolated from the Endophytic Fungus Chaetomium sp. Eef-10.

ABSTRACT: Four new depsidones, mollicellins O⁻R (compounds 1⁻4), along with three known compounds 5⁻7, were isolated from cultures of the fungus Chaetomium sp. Eef-10, an endophyte isolated from Eucalyptus exserta. The structures of the new compounds were elucidated by analysis of the 1D and 2D NMR and HR-ESI-MS spectra. The known compounds were identified by comparison of their spectral data with published values. Compounds 1⁻7 were evaluated for antibacterial activities against Staphylococcus aureus (sensitive and resistant strains), Escherichia coli, Agrobacterium tumefaciens, Salmonella typhimurium, Pseudomonas lachrymans, Ralstonia solanacearum, Xanthomonas vesicatoria and cytotoxic activiti
