The embodiments herein provide a composition and a method of synthesizing a composition comprising an aliphatic amino acid biosynthesis inhibitor having an antifungal activity. The composition comprises 2-oxo-2H-chromen-7-yl propiolate, diethyl-hex-2-en-4-yne-dioate and dinonyl-hex-2-en-4-yne-dioate. The composition inhibits a biosynthesis of an aliphatic amino acid in a fungal biological system. The aliphatic amino acid is selected from a group consisting of leucine, isoleucine and valine. The composition is used with a concentration of 0-200 μg/ml. The method comprises mixing solutions of dicyclohexylcarbodiimide (DCC) and Dimethylaminopyridine (DMAP) with alcohol, acetylene carboxylic acid and dichloromethane to obtain a mixture which is stirred filtered and washed with ether. The solvents are evaporated to obtain a residue that is dissolved in dichloromethane and stirred with a catalyst. The extra solvents are evaporated to obtain the derivative compound and purified by silica gel column chromatography.
本文提供了一种合成含有具有抗真菌活性的脂肪族氨基酸生物合成抑制剂的组合物和合成组合物的方法。该组合物包括2-氧代-2H-香豆素-7-基丙炔酸酯、二乙基-己-2-烯-4-炔二酸酯和二辛基-己-2-烯-4-炔二酸酯。该组合物在真菌生物系统中抑制脂肪族氨基酸的生物合成。脂肪族氨基酸选自亮氨酸、异亮氨酸和缬氨酸等一组氨基酸。该组合物的使用浓度为0-200μg/ml。该方法包括将二环己基碳二亚胺(DCC)和二甲基氨基吡啶(DMAP)的溶液与醇、乙炔羧酸和二氯甲烷混合,以获得混合物,该混合物经过搅拌、过滤和乙醚洗涤。然后蒸发溶剂以获得残留物,该残留物在二氯甲烷中溶解并与催化剂搅拌。额外的溶剂被蒸发以获得衍生物化合物,并通过硅胶柱层析纯化。
