title: Synthesis and antitumor activity of new D-galactose-containing derivatives of doxorubicin.
abstract: A general scheme of synthesis of antibiotic doxorubicin derivatives is based on the 13-dimethyl ketal of 14-bromodaunorubicin (4). The interaction of 4 with melibiose (5), lactose (6), 3-methoxy-4-O-(2,3,4,6-tetra-O-acetyl-beta-D-galactopyranosyl)-4-oxybenzaldehyde (12) or 4-O-(2,3,4,6-tetra-O-acetyl-beta-D-galactopyranosyl)-4-oxybenzaldehyde (13) by reductive alkylation followed by hydrolysis of the corresponding intermediate bromoketals produced 3'-N-[alpha-D-galactopyranosyl-(1-->6)-O-1-deoxy-D-glucit-1-yl]doxorubicin (7), 3'-N-[beta-D-galactopyranosyl-(1-->4)-O-1-deoxy-D-glucit-1-yl]doxorubicin (8), 3'-N-[3"-methoxy-4"-O-(beta-D-galactopyranosyl)-4"-oxybenzyl]doxorubicin (16), and 3'-N-[4"-O-(beta-D-galactopyranosyl)-4"-oxybenzyl]doxorubicin (17). Cytotoxic and antitumor activity of the synthesized drug candidates compared to the parent doxorubicin was studied using various experimental models, in particular, on mice bearing lymphocyte leukemia P-388 at single and multiple i.v. injection regimens.
