Sperabillins, novel antibiotics, were isolated from the culture filtrate of Pseudomonas fluorescens YK-437. The structure of sperabillin A was elucidated to be 3-[[(3R,5R)-3-amino-6-[(2E,4Z)-2,4-hexadienoylamino]-5-hydroxyhexanoyl]amino]propanamidine dihydrochloride. Sperabillin B has a methyl substituent at the C-6 position of sperabillin A. Sperabillin C and D are (2E,4E)-isomers of the 2,4-hexadienoyl moiety of sperabillin A and B, respectively.
从荧光假单胞菌 YK-437 的培养滤液中分离出了新型抗生素--斯佩拉比林。经阐明,斯佩拉比林 A 的结构为 3-[[(3R,5R)-3-氨基-6-[(2E,4Z)-2,4-己二烯酰氨基]-5-羟基己酰]氨基]丙脒二盐酸盐。sperabillin C 和 D 分别是 sperabillin A 和 B 的 2,4-己二烯酰基的 (2E,4E)-异构体。
