摘要： Two new 1,4,6-trihydroxy-8-alkylated-9,10-anthraquinones (1-2) were isolated from the culture broth of the soil actinomycete Streptomyces sp. WS-13394. Their structures were elucidated on the basis of extensive spectroscopic analysis, including mass spectrometry (MS), nuclear magnetic resonance (NMR), and electronic circular dichroism (ECD). Compounds 1 and 2, together with eight analogs (3-10), were evaluated for their antibacterial activities against five pathogens. The tested derivatives of alkylated anthraquinone exhibited selective activities to Gram-positive bacteria, while compounds 1 and 5 showed obvious activities against two zoonotic pathogens, Erysipelothrix rhusiopathiae and Streptococcus suis, with MIC values ranging from 3.13 to 12.5 mu g ml(-1).
