| dc.description.abstract | Chromones are a class of oxygen heterocyclic compounds widely distributed in Nature. 2-Styrylchromones are, however, a small and rare naturally occurring chromones; only three derivatives have been isolated, two from the marine blue green algae Chrysophaeum taylori1 and one from the rhizomes of Imperata cylindrical. Even so, 2-styrylchromone derivatives are associated with noticeable biological activities. Our group has also been interested in the synthesis and biological evaluation of 3-aroylflavones and found that 3’,4’,5,7-tetrahydroxy-3-(3,4-dihydroxybenzoyl)flavone is a potential antioxidant agent. As part of our continuing work on the synthesis and antioxidant evaluations of polyhydroxy-2-styrylchromones,4 we set up a program aiming the synthesis of 3-cinnamoyl-2-styrylchromone (2) bearing hydroxyl groups, features considered essential to be good antioxidant and anti-inflammatory agents. | en |
