摘要: 以取代苯甲酰肼为原料,设计合成了17种苯甲醛苯甲酰腙类化合物,并采用1H NMR和13C NMR确定目标化合物的结构。以醚菌酯为阳性对照,测定所有化合物对西瓜枯萎病原菌(Fusarium oxysporium f. sp. Niveum)、番茄早疫病原菌(Alternaria solani)、烟草赤星病原菌(Alternaria alternata)、玉米弯孢病原菌(Curvularia lunata)、苹果炭疽病原菌(Colletotrichum gloeosporioides)、南瓜枯萎病原菌(Fusarium bulbigenum)、苹果腐烂病原菌(Valsa mali)、水稻稻瘟病原菌(Pyricularia oryza)、苹果轮纹病原菌(Physalospora piricola)9种常见植物病原真菌的体外抑制活性。结果表明,17种化合物均有不同程度的抑制活性,其中,化合物A11的活性最高,对除西瓜枯萎病原菌外的8种供试真菌的抑制率高于醚菌酯,其EC50均小于醚菌酯。对活性数据进行初步分析,发现引入-F和-Me活性基团,相应化合物的抗真菌活性显著提高。

Abstract: Seventeen benzaldehyde benzoyl hydrazone compounds were designed and synthesized from substituted benzoyl hydrazides. The structures of the target compounds were determined by 1H NMR and 13C NMR. The in vitro inhibitory activities of all compounds against 9 common plant pathogenic fungi Fusarium oxysporium f. sp. Niveum, Alternaria solani, Alternaria alternate, Curvularia lunata, Colletotrichum gloeosporioides, Fusarium bulbigenum, Valsa mali, Pyricularia oryza, and Physalospora piricola were determined using kresoxim-methyl as the positive control. The results showed that 17 compounds had different degrees of inhibitory activities, and compound A11 had the highest activity. The inhibition rate of 8 tested fungi was higher than that of kresoxim-methyl except Fusarium oxysporium f. sp. Niveum, and its EC50 was also lower than that of kresoxim-methyl. Preliminary analysis of the activity data showed that the antifungal activity of the corresponding compounds was significantly improved by introducing -F and -Me active groups.
