Active compounds were subsequently tested against C. fragariae, C. gloeosporioides, C. acutatum, Phomopsis obscurans, P. viticola, Botrytis cinerea and Fusarium oxysporum. The study identified 2‐chloro‐N‐[2,6‐dichloro‐4‐(trifluoromethyl)phenyl]acetamide (7a) as showing the strongest antifungal activity, and the broadest activity spectrum in this set against Colletotrichum acutatum (at 48 and 72 h) and
三氟甲基苯基酰胺 (TFMPA) 被设计和合成为潜在的杀虫剂。使用直接生物自显影分析评估了 33 个结构对三种炭疽菌的杀真菌活性。随后针对草莓角斑病菌、胶球孢子菌、尖头角孢菌、暗色拟拟芽孢菌、葡萄球菌、灰葡萄孢和尖孢镰刀菌测试了活性化合物。该研究确定 2-氯-N-[2,6-二氯-4-(三氟甲基)苯基]乙酰胺 (7a) 显示出最强的抗真菌活性,并且在该组中对尖刺炭疽菌(48 和 72 h) 和 Phomopsis viticola(在 144 小时)。三乙胺与 N-[2,6-dichloro-4-(trifluoromethyl)phenyl]-2,2,3,3,3-pentafluoropropanamide (7b') 的络合物的存在在生物活性中起重要作用,并且取决于浓度或真菌种类,它显示出比母体酰胺更高或更低的活性。X 射线晶体学表明,配合物 (7b') 是一个离子对 (C10H2Cl2F8NO)−
