Abstract
Three naturally new C-glycosylated benz[α]anthraquinone derivatives, urdamycinone E (1), urdamycinone G (2), dehydroxyaquayamycin (3) have been isolated from the marine Streptomycetes sp. BCC45596. Urdamycin E (4), the possible biosynthetic precursor of 1-3, has also been identified after a re-cultivation of the strain. These compounds (1-4) exhibited potent anti-Plasmodium palcifarum K1 strain with IC 50 values in a range of 0.0534-2.93 μg/mL and anti-Mycobacterium tuberculosis with minimum inhibition concentrations (MICs) in a range of 3.13-12.50 μg/mL. Cytotoxicity against KB, MCF-7, NCI-H187, and Vero cells was also evaluated. © 2012 Phytochemical Society of Europe.
