摘要:
根据光谱数据阐明了从美洲商陆(Phytolacca americana)种子中分离出来的新木质素异美洲醇 A (1) 和美洲醇 A (2)的结构,然后通过与以前已知的异美洲素 A (3) 和美洲素 A (4) 的化学相关性进行了确认。研究发现,在 10-5 M 的浓度下,异美加仑醇 A、美加仑醇 A 和美加仑素 A 能增强胎鼠半球神经细胞系统中胆碱乙酰转移酶的活性。
The structures of new neo-lignans, isoamericanol A (1) and americanol A (2) isolated from the seeds of Phytolacca americana have been elucidated on the basis of spectroscopic data and then confirmed by chemical correlation with the previouslty known isoamericanin A (3) and americanin A (4). Isoamericanol A, americanol A, and americanin A have been found to enhance choline acetyltransferase activity at 10-5 M in a cultured neuronal cell system derived from fetal rat hemisphere.
