Abstract
Fatty acid are the major energy source for the myocardium, thus radiolabeled fatty have often employed as heart imaging agent to localize ischemia and as potential probes of myocardial metabolism. This paper presents the synthesis of phenyl-pentadecanoic acid (PPA) by alkylation reaction and Wollf-Kishner method. Finally, PPA was iodinated with thallium trifluoroacetate on localizing para-position of phenyl ring and radioiodine was exchanged. The overall chemical yield was 20%, labelling yield 95%, radiochemical purity 98%. Tissues distribution of mice shows that IPPA was very high activity in mice heart muscle. Autoradiogram of mouse section at 2 min is clear.
