The re-emergence, in the recent years, of cyclooxygenase as a biological target in therapeutic areas other than
inflammation is likely to require new optimized leads, particularly suited for the requirements of specific drug development
programs. We developed a convenient synthesis of the known imidazole-based selective COX-2 inhibitors bearing
primary sulphonamide and methyl sulfone substituents, via Pd-catalyzed imidazoline N-arylation as a key step, followed
by dehydrogenation.
近年来,环氧化酶作为生物靶点重新出现在炎症以外的治疗领域,这可能需要新的优化线索,特别是适合特定药物开发计划要求的线索。我们开发了一种简便的合成方法,通过钯催化咪唑啉 N-芳基化作为关键步骤,然后进行脱氢反应,合成出含有初级磺酰胺和甲基砜取代基的已知咪唑类选择性 COX-2 抑制剂。
