Hemodynamic effects of potentially useful antineoplastic agents
Adenosine (Ado) and Ado analogues produce multiple hemodynamic effects including coronary vasodilation, bradycardia, alterations in left ventricular contractility, and peripheral vasodilation or vasoconstriction depending on the vascular bed. The intact anesthetized Sprague-Dawley rat was examined in relation to electrocardiogram and blood pressure alterations induced by a series of potentially useful antineoplastic agents that are purine or pyrimidine analogues as part of a preclinical evaluation of these agents. The drugs tested were arabinosyladenine and its 5'-monophosphate derivative arabinosyladenine-5'-monophosphate (ara-AMP), the 2-fluoro derivative of ara-AMP, the pyrazolo[4,3-d]pyrimidines (formycin and formycin B), 8-azaadenosine, 6-methylmercaptopurine riboside, tricyclic nucleoside-5'-monophosphate, 5-fluorouracil, arabinosylcytosine, and 3-deazauridine. Those Ado analogues subject to deamination by adenosine deaminase (ADA) were also studied in the intact Sprague-Dawley rat after pretreatment with the ADA inhibitor 2'-deoxycoformycin. The results indicate that these agents have significant hemodynamic effects and should alert clinicians to potential adverse reactions when infusing these drugs
