A new antibiotic, aldecalmycin, has been discovered in the culture broth of Streptomyces sp. MJ147-72F6. Aldecalmycin was purified by solvent extraction, Diaion HP-20 chromatography, silica gel chromatography, Sephadex LH-20 chromatography, HPLC and centrifugal partition chromatography. The 1H and 13C NMR spectra of aldecalmycin showed the presence of keto-enol tautomers. Aldecalmycin is equipotent in inhibiting the growth of sensitive and methicillin-resistant Staphylococcus aureus (MRSA).
一种新的抗生素——醛霉素,已在链霉菌属MJ147 - 72F6的培养液中被发现。醛霉素通过溶剂萃取、Diaion HP - 20柱色谱法、硅胶柱色谱法、葡聚糖凝胶LH - 20柱色谱法、高效液相色谱法和离心分配色谱法进行纯化。醛霉素的1H和13C核磁共振谱显示存在酮 - 烯醇互变异构体。醛霉素在抑制敏感和耐甲氧西林金黄色葡萄球菌(MRSA)生长方面具有同等效力。
