Chaetolactam A (), an unprecedented azaphilone derivative bearing a unique 9-oxa-7-azabicyclo[4.2.1]octan-8-onering system, together with two new compounds, 11--chaetomugilide B () and chaetomugilide D () was isolated from an endophytic fungus, sp. g1. Notably, extensive NMR data analyses, NMR calculations with DP4 and DP4+ analyses, ECD calculations, and the RDC method were employed to establish the structure of . Furthermore, exhibited potent apoptosis induction activity by mediating caspase-3 activation and PARP degradation at 3 μM in HL-60.
从一株内生真菌 sp. g1 中分离得到了 Chaetolactam A（），这是一种具有独特的 9-氧杂-7-氮杂双环[4.2.1]辛烷-8-酮环系统的前所未有的氮杂菲酮衍生物，此外还分离得到了两个新化合物，11--chaetomugilide B（）和 chaetomugilide D（）。值得注意的是，通过广泛的 NMR 数据分析、NMR 计算与 DP4 和 DP4+分析、ECD 计算和 RDC 方法，确定了的结构。此外，在 3 μM 浓度下，通过介导 caspase-3 激活和 PARP 降解，表现出强烈的诱导细胞凋亡活性。
