  Syntheses and Biological Activities of Disaccharide Daunorubicins

  摘要：

  Carbohydrate moiety is found in many anticancer nature products. To explore the carbohydrate moiety of daunorubicin in enhancing anticancer efficacy, several daunorubicin derivatives bearing disaccharide (1-8) have been synthesized. Their cytotoxicities were tested in leukemia K562 and colon cancer SW620 cells. Topoisomerase II (topo II) poisoning was performed with the in vivo complex of topoisomerase bioassay. In both cell lines, compounds with various terminal 2,6-dideoxy sugars (compounds 1, 3, 5, and 8) showed 30- to 60-fold higher anticancer activity than compounds with 2-deoxy- or 6-deoxy sugar (compounds 6 and 7). Compounds with an alpha-linkage between two sugar units (compound 3) showed 35-fold higher anticancer activity than compounds with a beta-linkage (compound 4). In addition, the anticancer activities of these compounds correlated with their ability to target topo II mediated genomic DNA damage in vivo. Compounds 1 and 3 with 2,6-dideoxy sugars produced more covalent topo-DNA complex than compounds with 2-deoxy sugar (6) and 6-deoxy sugar (7). Compounds with an alpha-configuration of terminal 2,6-dideoxy sugar (compounds 1 and 3) showed higher topo II poisoning than their counterparts with the beta-configuration (compounds 2 and 4). These results indicate that sugar moieties in daunorubicin play a significant role in its anticancer activity and topo II inhibition. The second sugar of disaccharide daunorubicin should possess 2,6-dideoxy with alpha-linkage to the first sugar to exhibit better anticancer activity.

  An improved synthetic approach to 7[3-amino-4-O-(alpha-L-mycarosyl)-2,3,6-trideoxy-alpha-L-lyxo-hexopyranosyl]daunorubicinone (alpha 1) with high stereoselectivity and good yield was developed. The feature of its binding to human serum albumin (HSA) was also investigated under simulative physiological conditions via fluorescence and UV-vis absorption spectroscopy and molecular modeling methods. The results revealed that alpha 1 caused the fluorescence quenching of HSA by the formation of alpha 1-HSA complexes. Hydrophobic interactions played a major role in stabilizing the complex, which was in good agreement with the results of the molecular modeling study. In addition, the effect of common ions on the binding constants of alpha 1-HSA complexes at room temperature was also discussed. All the experimental results and theoretical data indicated that alpha 1 bound to HSA and was effectively transported and eliminated in the body. Such findings may provide useful guidelines for further drug design. (C) 2011 Published by Elsevier Ltd.
