新型2-甲基-3-呋喃甲酰胺类化合物的设计、合成及抑菌活性研究
Design, synthesis and antifungal activity of novel 2-methyl-3-furancarboxamide derivatives
摘要
Abstract
Based on the structure of the fungicide fenfuram for exploring high antifungal agents,twenty novel 2-methyl-3-furancarboxamide derivatives were designed,synthesized and characterized by1 H NMR.Then,their in vitro antifungal activities were evaluated against five normal phytopathogenic fungi (Rhizoctonia solani,Sclerotinia sclerotiorum,Ph ytophthora in f estans,P ythium a phanidermatum and Physalospora piricola) by mycelial growth inhibition method.In conclusion,compounds 1e,1f,2a,2b and 2f exhibited stronger antifungal effects on R.solani with inhibition rates of 88.6 %,74.5 %,78.5 %,78.7 % and 73.1 %,respectively,superior to commercial fungicide fenfuram (70.5 %).The EC50 values of the five tested compounds against R.solani showed that compound 1e exhibited the most potent inhibition with an EC50value of 2.824 mg/L which lower than that of fenfuram (EC50 =7.691 mg/L).As a result,compound 1e could be a lead compound forfurther research.关键词
