99mTc(CO)3-15-[N-(Acetyloxy)-2-picolylamino]pentadecanoic acid: a potential radiotracer for evaluation of fatty acid metabolism.

99mTc(CO)3-15-[N-(Acetyloxy)-2-picolylamino]pentadecanoic acid (1a) was prepared by incorporating [99mTc(CO)3]+ into 15-[N-(hydroxycarbonylmethyl)-2-picolylamino]pentadecanoic acid (2a). The overall radiochemical yield of 1a after HPLC purification was 60-63%. Radiotracer 1a was found to be chemically stable when incubated in human plasma for 4 h at 37… CONTINUE READING
