ABSTRACT:
The invention concerns novel flavone and isoflavone derivatives of formulae (Ia) and (Ib) wherein: X represents a group of formula —COOR, or —PO(OR)2; R represents a hydrogen atom or an alkaline or alkaline-earth metal, or a lower alkyl group; R1represents a hydroxy group, a lower alkoxy group or an acyloxy group; R2and R3, identical or different, represent a hydrogen or halogen atom, or a trifluoromethyl group, a trichloromethyl group, a hydroxy group, an alkoxy group or an acyloxy group comprising 1 to 5 carbon atoms, or R2and R3can combine to form an alkylene dioxy group. The invention is useful for rheumatic diseases.
