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.
从稀有放线菌菌株 Lechevalieria aerocolonigenes K10-0216 的发酵液中分离得到两种新的抗生素，分别命名为吡嗪霉素 A 和 B。通过硅胶和 HPLC 纯化得到吡嗪霉素 A 和 B。通过核磁共振和质谱确定吡嗪霉素 A 和 B 的化学结构为新型噻唑基吡啶化合物。吡嗪霉素 A 和 B 均表现出抗菌活性。
