Zorubicin  (Synonyms: Rubidazon; Rubidazone)

Zorubicin (Rubidazon) is a derivative of Daunorubicin (HY-13062A). Zorubicin interacts with topoisomerase II and inhibits DNA polymerases. Zorubicin can be used for the research of acute leukemias and sarcomas^{[1][2][3][4][5]}.

Zorubicin (0.1-1 μg/mL; 0-24 h) affects cell cycle^[2].
Zorubicin (0-128 nM/mL; 20 min) dose-dependently inhibits DNA polymerases α and β, and shows preferential inhibition of polymerase α^[3].

Zorubicin (12-18 mg/kg; i.p. 48 h after tumour cells injection) affects leukaemic colony forming units^[1].
Zorubicin (0.75-6.0 mg/kg; i.v.) increases plasma histamine concentrations and produces immediate hypotension in anesthetized beagle dogs^[3].
