摘要:
In the course of our screening program for bioactive compounds, a novel lipopeptide, nostofungicidine (1), was isolated from the methanolic extract of a field-grown terrestrial blue-green alga, Nostoc commune. The structure of nostofungicidine was elucidated by chemical degradation and extensive NMR measurements including DQF-COSY, HOHAHA, HMBC, and ROESY techniques. Nostofungicidine contains a novel beta-amino acid 3-amino-6-hydroxy stearic acid (Ahs) in its structure. (C) 1998 Elsevier Science Ltd. All rights reserved.
