Free radical reactions of daunorubicin

  • 1. Paris-5 Univ., 75 (France)

Description

Daunorubicin is an antitumor antibiotic activated in vivo by reduction. Its mechanism of action involves DNA and topoisomerase attack, but side effects are cytotoxicity related to free radical formation. Therefore the mechanism of the one-electron reduction of the drug and the reactions of the daunorubicin transients towards compounds of biological interest have been studied by the methods of radiolysis, in order to provide possible explanations of the drug mechanism of action. Their relative importance in cellular conditions is discussed

Abstract (French)

La daunorubicine est un antibiotique antitumoral active in vivo par reduction. Au cours de cette reduction, des intermediaires radicalaires peuvent etre formes, et intervenir dans la toxicite de ce medicament. C'est pourquoi quelques reactions des formes transitoires de la daunorubicine avec des cibles d'interet biologique, ont ete etudiees par les methodes de la radiolyse. Leurs implications dans un milieu cellulaire sont discutees
