Abstract Piperine, a natural alkaloid isolated from black pepper (Piper nigrum), was subjected to alkaline hydrolysis to yield pipericacid. A series of amides were synthesized by treatment of pipericacid with piperidine-4-carboxylic acidderivatives via different routes. The synthesized amides were characterized by various spectral techniques like FT-IR, 1H NMR, and 13C NMR spectroscopy and evaluated
摘要 胡椒碱是从黑胡椒 ( Piper nigrum )中分离出来的天然生物碱,经过碱解可产生胡椒酸。以哌啶-4-羧酸衍生物为原料,通过不同的路线,合成了一系列酰胺类化合物。通过各种光谱技术(如 FT-IR、 1 H NMR 和13 C NMR 光谱)对合成的酰胺进行了表征,并评估了它们对病原真菌物种(即真菌)的抗真菌活性。镰刀菌、青霉菌和曲霉菌,采用毒食技术。所有衍生物都以剂量依赖性方式显示出针对各种真菌的显着活性。结果表明,在各种酰胺衍生物中,化合物7a对镰刀菌属和青霉属更有效,而化合物9b对曲霉属更有效。观察到测试真菌的菌丝体生长随着酰胺衍生物浓度的增加而减少。
