Biotransformation of Methyl Parathion by Glutathione S-Transferases [PDF]
Toxicological Sciences, 2004 The organo(thio)phosphate esters are one of the most widely used classes of insecticides. Worldwide, organophosphate insecticides (OPs) result in numerous poisonings each year. In insects, glutathione S-transferases (GSTs) play an important role in OP resistance; limited data suggest that GST-mediated O-dealkylation occurs in humans as well.

Aggregate, Volume 6, Issue 11, November 2025.To overcome poor molecular recognition in dilute solutions of tetraphenylethylene‐embedded cyclo[6]arenes, three macrocycles with functionalized cavities featuring diazine groups as endo‐binding sites are synthesized. Their recognition affinity continuously improves with increasing hydrogen‐bond acceptance of diazine groups.
