Abstract Thirty-six novel threoninamide carbamate derivatives were designed and synthesised using active fragment-based pharmacophore model. Antifungal activities of these compounds were tested against Oomycete fungi Phytophthora capsici in vitro and in vivo. Interestingly, compound I-1, I-2, I-3, I-6 and I-7 exhibited moderate control effect (>50%) against Pseudoperonospora cubensis in greenhouse
摘要 使用基于活性片段的药效团模型设计并合成了36种新型苏氨酸氨基甲酸酯氨基甲酸酯衍生物。在体外和体内测试了这些化合物对卵菌疫霉的抗真菌活性。有趣的是,化合物I-1,I-2,I-3,I-6和I-7在6.25μg/ mL的温室中表现出对立方假单胞菌孢子的中等控制作用(> 50%),优于对照。同时,这些化合物中的大多数对辣椒衣原体具有明显的抑制作用。其他九种真菌也进行了测试。更重要的是,某些化合物对菌核菌,核果假单胞菌和茄形假单胞菌在体外的EC 50值为3.74–9.76μg/ mL。该模型可能是可靠的,并且该方法可用于发现用于开发杀菌剂的先导化合物。
