Abstract Twenty-seven novel pyrazole carboxamides with diarylamine-modified scaffold were designed, synthesized and characterized in detail via 1H NMR, 13C NMR, IR and ESI-HRMS. Preliminary bioassays showed that some of the target compounds exhibited good antifungal activity against Rhizoctonia solani, Rhizoctonia cerealis and Sclerotinia sclerotiorum. Among them, compound 9c-7 exhibited the highest
摘要设计,合成并通过1H NMR,13C NMR,IR和ESI-HRMS详细表征了二十七种新型的带有二芳基胺修饰的支架的吡唑甲酰胺。初步的生物测定结果表明,某些目标化合物对茄状枯萎病菌,谷粒状枯萎病菌和菌核盘菌具有良好的抗真菌活性。其中,化合物9c-7表现出最高的对solani solani,R。grainis和S. sclerotiorum的抗真菌活性,IC50值分别为0.013、1.608和1.874μg/ mL。值得注意的是,化合物9c-7仍然在体内具有最高的对茄红假单胞菌的杀真菌活性,IC50值为22.21μg/ mL。分子对接模拟结果表明,化合物9c-7与受体蛋白琥珀酸脱氢酶的疏水口袋结合良好。
