Antimalarial and antitubercular C-glycosylated benz[α]anthraquinones from the marine-derived Streptomyces sp. BCC45596

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 IC₅₀ 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.
