Pterolactam (5-methoxypyrrolidin-2-one) is a heterocycle naturally occurring in plants. In an attempt to identify antifungal agents, a series of novel Mannich bases of amide derivated from Pterolactam have been designed, synthesized and their antifungal activities were evaluated on a panel of nine fungal strains and three non albicans candida yeasts species which have demonstrated reduced susceptibility to commonly used antifungal drugs. A third of the target compounds exhibited good to high antifungal activities on at least one strain with EC50 lower than the control antifungal agent. N,N'-aminals derivated from Pterolactam proved to be good candidates for the development of biosourced fungicides, with compound 3o being the most broader-spectrum agent, active against five strains and devoted of any cytotoxicity.

受到内酯酰胺启发的酰胺曼尼希碱的设计,合成和抗真菌活性。
翼内酰胺(5-甲氧基吡咯烷酮-2-酮)是天然存在于植物中的杂环。为了鉴定抗真菌剂,已设计,合成了一系列新颖的衍生自翼内酰胺的曼尼希酰胺酰胺基,并在一组九种真菌菌株和三种非白色念珠菌念珠菌酵母菌种上评估了它们的抗真菌活性,这些菌种均显示出对真菌的敏感性降低。常用的抗真菌药。三分之一的目标化合物对至少一种菌株表现出良好至较高的抗真菌活性,且EC50低于对照抗真菌剂。事实证明,衍生自翼内酰胺的N,N'-缩醛胺是开发生物源性杀菌剂的良好候选者,化合物3o是最广谱的杀真菌剂,对五种菌株具有活性,并具有任何细胞毒性。
