Description:

Recent results of the authors have demonstrated that the elevation of extracellular adenosine induced by the combined administration of dipyridamole, a drug inhibiting the cellular uptake of adenosine, and adenosine monophosphate (AMP), a soluble adenosine prodrug, mediates radioprotective effects in mice. Furthermore, it has been shown that this action is induced by at least two mechanisms: (1) protection by hypoxia as a result of the effects of treatment on the cardiovascular system (bradycardia, vasodilation), and (2) an enhanced regeneration of the radiation-perturbed hematopoiesis. Here, it was ascertained that the joint use of an optimal dose of noradrenaline given with dipyridamole and AMP combination eliminates the hypothermic and hypoxic effects of the treatment, but preserves the radioprotective action of dipyridamole and AMP combination in terms of hematopoietic recovery and partially also survival enhancing effects of the drugs in gamma-irradiated mice. These findings might be of importance for attempts to obtain available and tolerable radioprotective pharmacological prescriptions for clinical use.
