Eupolauridine, an indenonaphthyridine alkaloid, has been previously reported by us to exhibit antifungal activity. This study describes the synthesis of new alkyl and benzyl naphthyridinium/pyridinium analogs of eupolauridine as potential antifungal agents. A majority of the analogs exhibited antifungal activity against opportunistic pathogens such as Candida albicans and Cryptococcus neoformans. Several
先前我们已经报道过Eupolauridine(一种
茚并
萘啶
生物碱)具有抗真菌活性。这项研究描述了作为潜在的抗真菌剂的新的eupolauridine烷基和
苄基萘啶/
吡啶鎓类似物的合成。大多数类似物表现出针对机会病原体例如白色念珠菌和新型隐球菌的抗真菌活性。其中有几种在不同程度上还可以有效抵抗细菌(
金黄色葡萄球菌,MRS,假单胞菌和分枝杆菌)和疟疾寄生虫(恶性疟原虫)。许多类似物对人癌
细胞系也具有细胞毒性。
