Discovery and biological characterization of a novel mesoionic insecticide fenmezoditiaz

Pest Management Science, Volume 81, Issue 5, Page 2535-2552, May 2025.
Acetylcholine binding protein (AChBP) from the sea slug Aplysia californica was modified using site‐directed mutagenesis to create an insect‐like binding site enabling structure‐based compound design. Fenmezoditiaz is a systemic insecticide with a broad spectrum, lack of cross‐resistance and an additional tool for integrated pest management and ...
