Based on our initial design, we synthesized two series of coumarin ring-opening derivatives by the reactions of hydrolysis and methylation. Results of antifungal screening in vitro showed that the target compounds exhibited potent activity against the six common pathogenic fungi. Compounds 6b, 6e, 6g, 6i, 7b and 7c were identified as the most active ones, and the EC50 values of these active compounds
基于我们的初步设计,我们通过水解和甲基化反应合成了两个系列的香豆素开环衍生物。体外抗真菌筛选结果表明,目标化合物对六种常见病原真菌均表现出强效活性。化合物6b、6e、6g、6i、7b和7c被鉴定为活性最强的化合物,并进一步测试了这些活性化合物的EC50值。与常用的杀菌剂嘧菌酯 (0.0884 µM) 相比,化合物 6b (0.0544 µM) 和 6e (0.0823 µM) 对灰葡萄孢的活性有所提高。
