therefore , only adenosine infusion resulted in a measurable increase of adenosine triphosphate levels after 3 hours of reperfusion , but over a longer time period , ribose or 5-amino-4-imidazol-carboxamide riboside also can be expected to replenish reduced myocardial adenosine triphosphate faster than adenine nucleotide de novo synthesis .
