| Outline of Final Research Achievements |
Over the past two decades, increasing attention has been given to polymethoxyflavones (PMFs). Among them, nobiletin, one of the most abundant PMFs in citrus peel, has been of particular interest and its diverse properties beneficial to health have been reported by many research groups. However, systematic studies on the structure-activity relationships of PMFs have not been widely reported, with a few exceptions. we succeeded in developing a new synthetic method for nobiletin metabolites and congeners, which involves easier access to the highly oxygenated A-ring moiety. The synthesized PMFs showed potent inhibitory activity against pro-matrix metalloproteinase(MMP)-9 production on lens epithelial cells (LECs). Since MMP-9 expression plays an important role in various pathological states including cataract, tumor metastasis, etc., these compounds could be potent lead for chemotherapeutic agents for the treatment of those diseases.
