Novel purine analogues bearing nitrate esters were designed and synthesized in an effort to develop compounds triggering endogenous cardioprotective mechanisms such as ischemic preconditioning (IPC) or postconditioning (PostC). The majority of the compounds reduced infarct size compared to the control group in anesthetized rabbits, whereas administration of the most active analogue 16 at a dose of 3.8 mu mol/kg resulted on a significant reduction of infarct size, compared to PostC group (13.4 +/- 1.9% vs 26.4 +/- 2.3%). These findings introduce a novel class of promising pharmacological compounds that could be used as mimics or enhancers of PostC. (C) 2012 Elsevier Ltd. All rights reserved.
