摘要:
4-Diazo-3-methoxy-2,5-cyclohexandien-1-one, and pharmaceutically acceptable salts thereof, are antibiotics having antibacterial activity against a variety of gram positive and gram negative bacteria, particularly against anaerobic bacteria. The compound can be prepared by culturing aerobically Penicillium funiculosum A.T.C.C. No. 20783 in a culture medium containing assimilable sources of carbohydrates and nitrogen.
