Uses

Kawain is a plant extract that shows antioxidant activity through cyclooxygenase enzyme inhibition. May also be active in tumor suppression and apoptotic induction.

Definition

ChEBI: Kawain is a member of 2-pyranones and an aromatic ether.

Manufacturing Process

To 1170 g ethyl acetoacetate at 100-110°C was added a little at time 1605 g bromosuccinimide. After cooling to the mixture was added 300 ml of carbon tetrachloride. From the mixture was isolated ethyl ester of bromoacetoacetic acid which was distilled at 105-125°C/18 mm; yield 67%.
By condensation of the mixture 1400 g ethyl ester of bromoacetoacetic acid, 700 g bromosuccineimide, 500 ml benzene and 350 mg zinc was prepared (R)-5,6-dihydro-4-methoxy-6-styryl-2H-pyran-2-one; melting point 157°C, yield 60-70%.

Therapeutic Function

Anesthetic; Tranquilizer
