Structural replacements for the benzoxazinone protox inhibitors
摘要:
Substituted benzoxazinones are a class of highly active inhibitors of protoporphyrinogen oxidase (protox) which are effective at controlling grass and broadleaf weeds at low rates, As part of the process of optimization of the herbicidal activity of the 6-heterocyclic benzoxazinones, a number of replacements were prepared for the oxazinone ring. Quantitative structure-activity relationships (QSAR) were developed for the benzoxazinone replacements using molecular properties, and these were compared to published QSAR for the acyclic 2,4,5-trisubstituted arylheterocyclic protox inhibitors. That the molecular properties of the acyclic and bicyclic protox inhibitors are similar suggest they may be interacting with the same binding site. (C) 1999 Society of Chemical Industry.
