从不列颠哥伦比亚省地衣表面获得的一种未描述的链霉菌的实验室培养物可产生uncialamycin(1),一种新的烯二炔抗生素。通过光谱数据的分析,确定了uncialamycin(1)的结构。Uncialamycin(1)对革兰氏阳性和革兰氏阴性人类病原体(包括洋葱伯克霍尔德菌,囊性纤维化患者发病和死亡的主要原因)具有强效体外抗菌活性。
Laboratory cultures of an undescribed streptomycete obtained from the surface of a British Columbia lichen produce uncialamycin (1), a new enediyne antibiotic. The structure of uncialamycin (1) has been elucidated by analysis of spectroscopic data. Uncialamycin (1) exhibits potent in vitro antibacterial activity against Gram-positive and Gram-negative human pathogens, including Burkholderia cepacia, a major cause of morbidity and mortality in patients with cystic fibrosis.
