Phosphagens, also known as macroergic compounds, are high energy storage compounds, also known as high-energy phosphate compounds, chiefly found in muscular tissue in animals. They allow a high-energy phosphate pool to be maintained in a concentration range, which, if it all were adenosine triphosphate (ATP), would create problems due to the ATP-consuming reactions in these tissues. As muscle tissues can have sudden demands for lots of energy; these compounds can maintain a reserve of high-energy phosphates that can be used as needed, to provide the energy that could not be immediately supplied by glycolysis or oxidative phosphorylation. Phosphagens supply immediate but limited energy.

99mTc-labeled 19 amino acid containing peptide for use as phosphatidylethanolamine binding molecular probe and radiopharmaceutical
With only 19 amino acids, Duramycin is the smallest known polypeptide that has a defined 3-dimmensional binding structure. Duramycin binds Phosphatidylethanolamine (PtdE) at a 1:1 ratio with high affinity and exclusive specificity. As an abundant binding target, PtdE is a major phospholipid and accounts for about 20 % of the phospholipid content in mammalian cellular membranes. PtdE is externalized to the surface of apoptotic cells, and also becomes accessible in necrotic cells due to compromised plasma membrane integrity. Given the unique physicochemical properties of Duramycin and the availability of PtdE in acute cell death, the goal of this study is to develop and evaluate 99mTc-HYNIC-Duramycin as a novel molecular probe for imaging PtdE. 99mTc-HYNIC-Duramycin is a low-molecular weight, fast-clearing radiopharmaceutical that detects apoptosis / necrosis by binding to PtdE. The goal was to quantify the uptake of 99mTc-HYNIC-Duramycin in the area-at-risk after myocardial ischemia and reperfusion, and to determine the window of detection.
