title: Biochemical activities of the derivatives of dehydrodicaffeic acid dilactone.
abstract: Activities of derivatives of dehydrodicaffeic acid dilactone (DDCAD) to inhibit catechol-O-methyltransferase (COMT), cyclic AMP phosphodiesterase (PDE) and DOPA decarboxylase (DDC) were examined. Among those tested, 2,6-bis-(5',6'-dibromo-4'-hydroxy-3'-methoxyphenyl)-3,7-dioxabicyclo-[3,3,0]-octane 4,8-dione was found to be the strongest inhibitor of both COMT and PDE. There were no derivatives which showed a stronger inhibition against DDC than the original compound, DDCAD.
