摘要
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 ehromeno[8,7-e][1,3]oxazin-4-ones were syn- thesized 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 resuits, some target compounds show potent anti-inflammatory activity.
