二芳胺基呋喃甲酰胺类化合物的合成设计及抗菌活性研究
Design, synthesis and antifungal activity of novel furancarboxamide analogues containing a diarylamine moiety
摘要
Abstract
Carboxylic amides are one of the most important classes of agricultural fungicides.To discover new carboxylic amide analogues with high activity against plant pathogenic fungi,twenty novel furancarboxamide analogues containing a diarylamine moiety were designed,synthesized and characterized by 1 H NMR.Their antifungal activities in vitro were evaluated against four phytopathogenic fungi(Rhizoctonia solani,Sclerotinia sclerotiorum,Pythium aphanidermatum and Fusarium oxysporum) by mycelium growth inhibition method.Most compounds showed significant antifungal effect on R.solani and S.sclerotiorum,however,slightly weak antifungal effect on P.aphaniderrmatum and F.oxysporum.Compound li exhibited the most potent antifungal effect on S.sclerotiorum with EC50 value of 1.9229mg/L,superior to commercial fungicides boscalid (EC50 =2.6736 mg/L) and lead fungicide fenfuram (EC50 =9.9667 mg/L).The present work demonstrated that furancarboxamide analogues containing a diarylamine moiety could be used as a lead structure for further developing novel fungicides.关键词
