Carolacton - A Macrolide Ketocarbonic Acid that Reduces Biofilm Formation by the Caries- and Endocarditis-Associated Bacterium<i>Streptococcus mutans</i>
The macrolideketocarbonicacidcarolacton (1) was isolated from the myxobacterium Sorangium cellulosum, strain So ce960, because of its antibiotic activity. Subsequently, carolacton (1) was discovered to be a highly potent agent against biofilms containing the caries- and endocarditis-associated bacterium Streptococcus mutans. The 2D structure of 1 was elucidated by HRMS, IR and 2D NMR spectroscopy
大环内酯酮碳酸carolacton (1) 是从粘杆菌Sorangium cellulosum, So ce960 菌株中分离出来的,因为它具有抗生素活性。随后,carolacton (1) 被发现是一种高效的生物膜药剂,可以对抗含有龋齿和心内膜炎相关细菌变形链球菌的生物膜。通过HRMS、IR和2D NMR光谱阐明了1的2D结构。最初,立体中心是通过化学衍生结合计算方法确定的,最后通过 X 射线分析进行验证。
