Pyrizomicin A and B: structure and bioactivity of new thiazolyl pyridines from Lechevalieria aerocolonigenes K10-0216

The Journal of Antibioticsvolume 71pages606608 (2018) | Download Citation


Two new antibiotics, designated pyrizomicin A and B, were isolated from the cultured broth of a rare actinomycete strain, Lechevalieria aerocolonigenes K10-0216, by silica gel and HPLC purification. The chemical structures of pyrizomicin A and B were elucidated as new thiazolyl pyridine compounds by nuclear magnetic resonance and mass spectrometry. Pyrizomicin A and B both showed antimicrobial activity.
