Sansanmycins B and C, new components of sansanmycins
Abstract
Two new antibiotics, sansanmycins B and C, were isolated from Streptomyces sp. SS. Their structures were elucidated by extensive 1D and 2D NMR and MS spectral analyses. Sansanmycins B and C exhibited inhibitory activity against our test strain of Pseudomonas aeruginosa with MIC values of 8.0 and 16 microg/ml, respectively. Sansanmycin B also exhibited inhibitory activity against Mycobacterium tuberculosis H37Rv and multidrug-resistant Mycobacterium tuberculosis, with the MIC values ranging from 8.0 to 20 microg/ml.
