Abstract:
A novel flavone derivative is provided to show excellent antioxidative effect, neuron protecting effect and neuroethological effect, thereby being usefully used for preventing and treating various neurodegenerative diseases such as stroke, chronic degenerative disease, Parkinson's disease and Alzheimer's disease. The flavone derivative is represented by the formula(1), wherein R1 is H or C1-4 alkoxy, R2 is H or hydroxy, each R3 and R4 is independently H or R5, R5 is glucose or -(CH2)mR6(m is from 0 to 3), and R6 is tetrahydrobenzopyran, tetrahydrobenzopyranylalkylacetate or tetrahydrobenzopyranylalkoxyalkyl substituted by at least one substituent selected from the group consisting of C3-7 heterocyclic compound including at least one of N and O; amino which is substituted or unsubstituted by at least one C1-4 alkyl; hydroxy; and hydroxyalkyl. The method for preparing the flavone derivative according to the reaction formula(1) comprises the steps of: (a) synthesizing a compound represented by the formula(VI) from a compound of the formula(I); and (b) after introducing at least one amine or glucose into the compound of the formula(VI) to prepare a compound represented by the formula(VII), deprotecting the compound of the formula(VII) to synthesize the compound of the formula(1). In the reaction formula(1), each R1 to R6 is same as defined above, X is halogen or alkyl halogen, MOM is methoxymethyl, and Bn is benzyl.
