The aim of this study was to establish the effect of naturally occurring antioxidant carnosine (CAR) on the doxorubicin (DOX)-induced cardiotoxicity in a rabbit model. For this purpose, we evaluated the influence of DOX administration alone and in a combined therapy with CAR on the hemodynamic parameters and on the degree of cardiac muscle cell alterations in rabbits. Thirty one chinchilla rabbits were divided into four groups. One group of rabbits was injected iv with DOX at a dose of 2 mg kg… 

Figures and Tables from this paper

Amifostine improves hemodynamic parameters in doxorubicin-pretreated rabbits.

It is shown that pretreatment with doxorubicin at the total dose of 12 mg/kg significantly reduced CI and increased TPR in doxorbicin-pretreated rabbits, and amifostine improved CI and TPR on average in these animals.

Protective effect of carnosine on adriamycin-induced oxidative heart damage in rats.

An increase in oxidative stress, superoxide dismutase, glutathione peroxidase levels, catalase inactivation and cardiac dysfunction induced by adriamycin were prevented by carnosine.

Beneficial effects of carnosine and carnosine plus vitamin E treatments on doxorubicin-induced oxidative stress and cardiac, hepatic, and renal toxicity in rats

The results may indicate that CAR alone, especially in combination with Vit E, protect against DOX-induced toxicity in heart, liver, and kidney tissues of rats.

β-Alanine and orotate as supplements for cardiac protection

Many studies have concluded that β-alanine supplementation can both boost muscle carnosine content and aid performance in high-intensity anaerobic workouts in which lactic acid is generated, presumably by preventing counterproductive reductions in intracellular pH.

Reactive Carbonyl Species Scavengers—Novel Therapeutic Approaches for Chronic Diseases

The newly developed 2-aminomethylphenol class of scavengers shows great promise in preclinical trials for a number of diverse conditions including neurodegenerative diseases and cardiovascular disease and new studies with the thiol-based and imidazole-based scavengers have found new applications outside of adjunctive therapy for chemotherapeutics.

Melatonin was found to exert a protective effect on the cardiac muscle cells, which was particularly evident after acute doxorubicin or subchronic daunorubsicin intoxication, using either histological or biochemical methods.

DZR is highly effective in attenuating the cardiomyopathy caused by DOX, but dose ratios of DZR:DOX capable of providing total or nearly complete cardioprotection at low doses of DOX are less efficacious at higher doses ofdoxorubicin.

Timing of treatment with ICRF-187 and its effect on chronic doxorubicin cardiotoxicity

Observations were interpreted as indicating that the timing of administration of ICRF-187 with respect to that of doxorubicin is an important factor in determining the degree of cardioprotection and that there is a “time window” in which ICRf-187 exerts optimal effects.

Evaluation of 4′-Iodo-4′-Deoxydoxorubicin-Induced Cardiotoxicity in Two Experimental Rat Models

Although both models can be considered useful for evaluating and comparing the cardiotoxicity of new anthracycline derivatives and mimicking the transvenous endomyocardial biopsies in humans, the chronic test seems to be more suitable for compounds like I-DX, which possess a low cardiotoxic potential and which could go unnoticed in the single-dose test.

In tumor-bearing mice, amifostine reduces the lethality of high doses of doxorubicin without affecting antitumor activity, and in vitro studies in neonatal rat heart cells have shown direct evidence of anthracycline cardioprotection for both am ifostine and WR-1065.
