Eucapsitrione, an anti-Mycobacterium tuberculosis anthraquinone derivative from the cultured freshwater cyanobacterium Eucapsis sp.
Eucapsitrione (1), an anthraquinone derivative with an indeno-anthracene-trione skeleton, was isolated from the cyanobacterium Eucapsis sp. (UTEX 1519) by bioassay-guided fractionation. The chemical structure was determined by analyzing MS and 1D and 2D NMR spectroscopic data. Eucapsitrione (1) showed anti-Mycobacterium tuberculosis activity in the microplate Alamar blue assay and low-oxygen-recovery assay with MIC values of 3.1 and 6.4 microM, respectively.
