Permetin A was purified from the culture filtrate of Bacillus circulans AJ 3902 by extraction with n-butanol, precipitation with sodium helianthate, CM-cellulose column chromatography and Sephadex LH-20 column chromatography. The compound was found to be a new peptide antibiotic containing 2,4-diaminobutyric acid (Dab), leucine, isoleucine, phenylalanine, valine, serine (in a molar ratio of 3:2:1:1:1:1) and a fatty acid. This antibiotic showed activity in vitro against Gram-negative, Gram-positive and some anaerobic bacteria.
通过用正丁醇萃取、向日葵酸钠沉淀、CM-纤维素柱色谱和葡聚糖凝胶LH-20柱色谱从环状芽孢杆菌AJ 3902的培养滤液中纯化出Permetin A。发现该化合物是一种新的肽抗生素,含有2,4-二氨基丁酸(Dab)、亮氨酸、异亮氨酸、苯丙氨酸、缬氨酸、丝氨酸(摩尔比为3:2:1:1:1:1)和一种脂肪酸。这种抗生素在体外对革兰氏阴性菌、革兰氏阳性菌和一些厌氧菌具有活性。
