Evaluation of structure effects on the pharmacological behavior of radioiodinated phenylpentadecanoic acids
Description: For studying the pharmacokinetic behaviour of fatty acids with different chemical structures four STI-labelled compounds, i.e., the ortho and para STI-isomers of 15-phenylpentadecanoic acid (IPPA) and 3-methyl-15-phenylpentadecanoic acid were prepared and the organ distribution determined in mice. The results show a significant decrease of the maximal heart uptake for the two ortho compounds. Further, the hypothesis of a blocked metabolism as an effect of the US -methylation could not be confirmed. Both US -methylated compounds show a biexponential elimination behavior from the heart. 5 refs., 2 figs.
