The synthesis and pharmacological evaluation of 7-O-(4-O-acetyl-3-iodo-2,3,6-trideoxy-alpha-L-arabino-hexopyranosyl) daunomycinone and 7-O-(3-chloro-2,3,6-trideoxy-4-O-propanoyl-alpha-L-lyxo-hexopyrano syl) daunomycinone are described. Their cytotoxic activity was evaluated against normal and resistant cell lines. Both compounds exhibited activity against the adriamycin resistant cell line KB-A1. These results support the hypothesis that the increased lipophilicity of the sugar part of anthracyclines is associated with their ability to overcome multidrug resistance (MDR).
