Synthesis and optimization of 2-pyridin-3-yl-benzo[d][1,3]oxazin-4-one based inhibitors of human neutrophil elastase
摘要:
The hit-to-lead optimization of the HNE inhibitor 5-methyl-2-(2-phenoxy-pyridin-3-yl)-benzo[d][1,3]oxazin-4-one is described. A structure-activity relationship study that focused on the 5 and 7 benzoxazinone positions yielded the optimized 5-ethyl-7-methoxy-benzo[d][1,3]oxazin-4-one core structure. 2-[2-(4Methyl-piperazin-1-yl)-pyridin-3-yl] derivatives of this core were shown to yield HNE inhibitors of similar potency with significantly different stabilities in rat plasma.

The present invention relates to a composition for dyeing keratin fibres, in particular human keratin fibres such as the hair, comprising one or more oxidation bases and one or more particular aminobenzene couplers. The invention also relates to a process for dyeing keratin fibres using said composition in the presence of one or more chemical oxidizing agents, and to a multi-compartment device suitable for using said dye composition.
