Abstract

Trachyspic acid, a new metabolite that inhibited heparanase, was isolated from the culture broth of Talaromyces trachyspermus SANK 12191. Its structure was deduced from NMR spectral analyses and chemical reactions as a tricarboxylic acid derivative containing a spiroketal. The IC50 value of trachyspic acid against heparanase was 36 microM.

摘要

从曲霉菌Talaromyces trachyspermus SANK 12191的培养液中分离出一种新的代谢产物——曲霉菌酸,它能够抑制乙酰肝素酶。通过核磁共振光谱分析和化学反应推断其结构为一种含有螺缩酮的三羧酸衍生物。曲霉菌酸对乙酰肝素酶的IC50值为36微摩尔。
