Alkylsulfones: novel chemical scaffolds targeting the vesicular acetylcholine transporter usher in a new generation of insecticides.

Insecticides targeting the nervous system have been the most widely used to control arthropod pests due to their fast onset of action leading to efficient crop protection. With their continued use, resistance has and will become an inevitable challenge that demands continued efforts in identifying and developing new insecticidal chemistries acting on novel targets. In a recent publication, the results of a comprehensive study investigating the mode of action of novel chemical scaffolds based on the 2-(3-ethylsulfonyl-2-pyridyl)-heterocycles, alkylsulfones, was presented, concluding that their primary target is the vesicular acetylcholine transporter. © 2024 Society of Chemical Industry.
