Abstract

The monocationic 67Cu complex of N-(2-pyridylmethyl)-N'- (salicylaldimino)-1,3-propanediamine was obtained in high radiochemical purity by reaction of 67Cu2+ with the ligand in ethanol solution. Although this compound exhibited low heart uptake, the desired myocardial retention was observed over the 30 min time period studied in a rat model. Since the octanol/water partition coefficient of [67Cu]Cu(II)-[N-(2- pyridylmethyl)-N'-(salicylaldiminato)-1,3-propanediamine] is lower than a value believed to be the optimal myocardial uptake, it is likely that derivatives of this compound with a higher lipophilicity merit further investigation for use in myocardial imaging with copper radioisotopes.
