Abstract:

Flavonoids exhibit a wide range of biological activities including anti-inflammatory activity, while some 1,3-benzoxazine derivatives show anti-inflammatory activity. In order to explore the novel anti-inflammatory agents, based on the principles of bioisosterism and hybridization, ten novel chromeno[8,7-e][1,3]oxazin-4-ones were synthesized and characterized with IR, 1H NMR, MS and elemental analyses. The anti-inflammatory activities of the target compounds were evaluated via the croton oil-induced ear oedema test in Swiss mice. According to screened results, some target compounds show potent anti-inflammatory activity.

Key words: Anti-inflammatory activity; Heterocycle; Flavone; Chromeno[8,7-e][1,3]oxazin-4-one
