Abstract: The main objective of this study was to evaluate the biological activity of a new compound (derived from aza-bicyclo-carboxylic acid) against heart failure caused by the ischemia- reperfusion phenomenon. In addition, to characterize de molecular mechanism involved in the effect exerted by aza-bicyclo-carboxylic acid against infarction area, some drugs such as prazosin, metoprolol, propanolol, tamoxifen, flutamide, finasteride, nifedipine, levosimedan, adenosine, rolofylline, isoproterenol and the compound ZM-241385 were used as pharmacological tools.  The data found indicated that biological activity induced by compound 3 on infarction area only was similar at effect exerted by adenosine; however, the effect produced by compound 3 was blocked with of rolofylline. Other data showed that the biological activity of compound 3 decreases the cAMP levels in a time-dependent manner. In conclusion, the results indicate that compound 3 can produce a cardioprotective effect against myocardial ischemia-reperfusion injury translated as a decrease on infarction area; this phenomenon involves A1-adenosine receptor activation and, as a result may cause changes in cAMP levels.
