-
, (2012/11/08)
The present invention relates to a method for the synthesis of 4-demethoxydaunorubicin (idarubicin) having the chemical structure of formula (I), which involves the demethylation of 3′-Prot-daunorubicin in the presence of a soft Lewis acid. The method of the present invention does not comprise cleavage of the glycosidic linkage at carbon C7, thus resulting in a faster synthesis cycle and an improved yield of the final product.

Doxorubicin and 14-hydroxycarminomycin 14-O-hemiadipates and 14-O-hemipimelates (synthesized from 14-bromo derivatives of daunorubicin, carminomycin monosodium adipate, and pimelate) were converted to the corresponding N-trifluoroacetylated compounds. 13-(4-methylpiperazine-1-yl)imino derivatives of the anthracycline antibiotics were also obtained.The cytostatic activity of the compounds synthesized was studied using a panel of human and animal tumor cell lines sensitive or resistant to doxorubicin.N-Trifluoroacetylation of the antibiotics resulted in a decrease in the cytostatic activity.The activity of the water-soluble 13-(4-methylpiperazine-1-yl)imino derivatives is close to that of the corresponding parent antibiotics. - Keywords: anthracycline antibiotics; multidrug resistance
