| Outline of Final Research Achievements |
The aim of this study was to develop highly-sensitive apoptosis imaging agent for early prediction of anti-cancer therapy. One of the early biochemical changes of apoptotic cells is exposure of phosphatidylserine (PS) on the external surface of the plasma membrane. The LIKKPF, with high affinity for PS, was selected as a mother compound, then D-amino acid peptide fpkkil-NH2 was designed and prepared considering stability. The fpkkil-NH2 maintained affinity to PS and was stable in vivo. Thus, radiolabeled fpkkil-NH2 derivatives will be useful as apoptosis imaging agents.
