Abstract

5-Methoxy-8-(2-hydroxy-3-buthoxy-3-methylbutyloxy)-psoralen (MP) is a medicinal herbal product isolated from Angelica dahurica that inhibits the cyclooxygenase-2 (COX-2)-dependent phase of prostaglandin D2 (PGD2) generation in bone marrow-derived mast cells (IC50, 23.5 μM). Western blotting with specific anti-COX-2 antibodies showed that the decrease in PGD2 production was accompanied by a decrease in COX-2 protein levels. In addition, this compound consistently inhibited the production of leukotriene C4 in a dose dependent manner, (IC50, 2.5 μM). These results demonstrate that MP inhibits both cyclooxygenase-2 and 5-lipoxygenase activity. Furthermore, this compound also inhibited the degranulation reaction (IC50, 4.1 μM). Therefore, this compound might provide a basis for novel anti-inflammatory drug development.
