for a growing world population to protect crops and animal and human health. New chemotypes modulating the insect nicotinic acetylcholine receptors have been recently brought to the agricultural market, yet with limited understanding of their molecular interactions at their target receptor. Herein, we disclose the first crystal structures of these insecticides, namely, sulfoxaflor, flupyradifurone, triflumezopyrim
对于不断增长的世界人口而言,开发新型安全杀虫剂仍然是保护农作物、动物和人类健康的重要需求。调节昆虫烟碱乙酰胆碱受体的新化学型最近已进入农业市场,但对其靶受体的分子相互作用了解有限。在此,我们在模拟昆虫离子通道正构位点的双突变乙酰胆碱结合蛋白中披露了这些杀虫剂的第一个晶体结构,即磺胺嘧啶、氟吡呋喃酮、氟虫嘧啶、氟嘧啶和实验化合物 dicloromezotiaz。通过这些发现,我们发现了具有相关作用模式的新型药效团,我们在本文中描述了它们的设计、合成和生物学评估。
