The Molecular Properties of Honey Bee Acetylcholinesterase Reveal Opportunities to Avoid Off‐Target Effects in Insecticide Discovery

open access: yesChemistry – A European Journal, EarlyView.
The structure, dynamics, and kinetics of the essential enzyme acetylcholinesterase (AChE) of honey bee have been studied and compared to AChEs in mosquitoes and mammalians. Profiling of the active sites with selected substrates and AChE inhibitors revealed dramatic differences between the species.

Rethinking Chlorine: Essential Chemical or Replaceable Risk?

open access: yesChemSusChem, EarlyView.
Chlorine is essential for the production of plastics and pharmaceuticals but poses significant safety and environmental risks. Herein, processes are presented that substitute chlorine or reduce its demand. Where indispensable, trichloride‐ and bichloride‐based ionic liquids could enhance safety and streamline the integration of renewable energy ...
