Cytostatic activity of daunorubicin analogs containing daunosamine as furanoside

Kuszmann,Medgyes,Dvortsak,Tory

, p. 786 - 789 (2007/10/02)

This paper describes the synthesis of daunorubicin (daunomycin) analogs, differing from the natural antibiotics in the ring size of the sugar moiety (furanosides instead of pyranosides). Both, the 5-O-methyl derivative 7 as well as the daunosaminofuranoside 16 were less active cytostatics than doxorubicin (adriamycin), but 16 was also much less toxic, consequently its therapeutic index is more favourable.
