Diumycin A, a new antibiotic, was found to inhibit cell wall synthesis by Staphylococcus aureus, a phenomenon accompanied by accumulation of uridine-5'-diphosphate-N-acetyl-muramyl-pentapeptide. The antibiotic inhibited in vitro peptidoglycan synthesis by particulate preparations of Bacillus stearothermophilus and Escherichia coli by preventing the utilization of N-acetyl-glucosamine-N-acetyl-muramyl-pentapeptide. In contrast to vancomycin, the antibiotics diumycin, prasinomycin, moenomycin, 11.837 RP, and enduracidin do not inhibit particulate d-alanine carboxypeptidase.
新抗生素迪尤霉素A被发现可抑制金黄色葡萄球菌细胞壁的合成,此现象伴随着尿苷-5'-二磷酸-N-乙酰胞壁酰五肽的积累。该抗生素通过阻止N-乙酰葡糖胺-N-乙酰胞壁酰五肽的利用,在体外抑制嗜热脂肪芽孢杆菌和大肠杆菌的颗粒制剂的肽聚糖合成。与万古霉素不同,抗生素迪尤霉素、prasinomycin、莫能菌素、11.837 RP和耐久霉素不抑制颗粒性D-丙氨酸羧肽酶。
