, (2008/06/13)
Novel flavonoids of formula (I) 1where A and E form together a C—C or C=C bond; R1, R2, R3, and R4 are H, OH, O(CH2)n— aromatic group, n=0-8; O(CH2)n N(CH3)q with n=0-8, q=0-3; O(CH2)n OH with n=1-8; O(CH2)n-halide with n=1-8; O(CH2)n COOH with n=0-8; O(CH2)n COOR′ with n=0-8 and R′ is C1-C8 alkyl or an aromatic group; O(CH2)n CONH R″ with n=0-8 and R″ is C1-C8 alkyl or an aromatic group, and sugars in mono-, di- or trimeric form or analogues thereof, with the proviso that R1 is not H, at least two of R2, R3 and R4 are H, and at most one of R1, R2, R3 and R4 is OH, are useful for the treatment of drug-induced toxicity, doxorubicin-induced cardiotoxicity, free radical mediated diseases, lung diseases, cancer, diabetes mellitus, cardiovascular disease, or arteriosclerosis.
