Popis: The new hydrophilic derivatives of 14-hydroxycarminomycin were obtained using 13-dimethyl ketal of 14-bromocarminomycin (6) as the starting compound. The reductive alkylation of 6 with melibiose or D-galactose followed by hydrolysis of the corresponding intermediate bromoketals 9 and 11 produced 3'-N-[-alpha-D-(galactopyranosyl-(1 --6)-O-D-1-desoxyglucit-1-yl]-14-hydroxycarminomycin (10) and 3'-N-(1-desoxy-D-galactit-1-yl)-14-hydroxycarminomycin (12), respectively. These novel derivatives 10 and 12 were less toxic than carminomycin or 14-hydroxycarminomycin for leukemia (K562) and breast carcinoma (MCF-7) cells. Importantly, carminomycin, 14-hydroxycarminomycin and compounds 10 and 12 were similarly active for wild type cells and their multidrug resistant (MDR) sublines, K562i/S9 and MCF-7Dox.
