PZ-51 (Ebselen) in vivo protection against adriamycin-induced mouse cardiac and hepatic lipid peroxidation and toxicity

Biochem Pharmacol. 1992 Aug 18;44(4):839-41. doi: 10.1016/0006-2952(92)90427-k.


Adriamycin (Adr)-induced cardiotoxicity occurs most likely via an oxidative mechanism of action. Moderation of this activity may result in an improved therapeutic index for this compound. PZ-51, 2-phenyl-1,2-benzoisoselenazol-3(2H)-one, is a selenoorganic compound with thiol-dependent, peroxidase-like activity. We tested this compound alone and in combination with N-acetylcysteine (NAC) for its effect on Adr-induced in vivo toxicity in Balb/c mice. These studies demonstrated that PZ-51 protects against Adr-induced lipid peroxidation in heart and liver tissue and Adr-induced toxicity in general, as measured by total serum creatine kinase activity and body weight.
