Antibiotic bisanthraquinones produced by a streptomycete isolated from a cyanobacterium associated with Ecteinascidia turbinata.

چکیده
Chemical studies of a streptomycete isolated from a cyanobacterium associated with the tropical tunicate Ecteinascidia turbinata led to the bioassay-guided purification of two antibacterial bisanthraquinone metabolites and a cytotoxic artifact. The structures, including relative configurations of these octacyclic compounds, were established by spectroscopic analyses. Their potent antibacterial properties (IC(50) = 0.15-130 microM) versus methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus faecalis and cytotoxic effects against HCT-116 cells are presented.

Two novel chlorinated pyrones, halomadurones A and B, and two novel brominated analogues, halomadurones C and D, were isolated from a marine Actinomadura sp. cultivated from the ascidian Ecteinascidia turbinata. Additionally, a non-halogenated analogue, 2-methyl-6-((E)-3-methyl-1,3-hexadiene)-γ-pyrone, was synthesized to understand the role of the halogens for activity. Halomadurones C and D de...

A polyether antibiotic, ecteinamycin (1), was isolated from a marine Actinomadura sp., cultivated from the ascidian Ecteinascidia turbinata. 13C enrichment, high resolution NMR spectroscopy, and molecular modeling enabled elucidation of the structure of 1, which was validated on the basis of comparisons with its recently reported crystal structure. Importantly, ecteinamycin demonstrated potent ...
