The synthesis and biological evaluation of 5-hydroxy clausenamide (CM2), one of the major metabolites of clausenamide, and its stereoisomers have been carried out. The absolute configurations of (−)- and (+)-CM2 were assigned as 3S,4S,5S,6S and 3R,4R,5R,6R respectively based on 1H NMR spectroscopic investigation and their chemical correlation to (−)- and (+)-clausenamidone (3).

进行了5-氨基水杨酰胺的主要代谢产物之一的5-羟基水杨酰胺(CM 2)及其立体异构体的合成和生物学评价。基于1 H NMR光谱分析,(-)-和(+)-CM 2的绝对构型分别指定为3 S,4 S,5 S,6 S和3 R,4 R,5 R,6 R。它们与(-)-和(+)-clausenamidone(3)的化学相关性。电生理分析表明化合物(+)-CM 2及其C 6差向异构体(+)- 8a 对突触传递有显着影响,因此诱导了齿状回的长期增强。
