↵3-a Structures of metabolites are shown in Fig. 7 except for metabolite M10, which was identified as the symmetrical disulfide of omapatrilat.
↵3-b Radioactive peaks are reported as a percentage of the total radioactivity eluted from the column after background subtraction. The recovery of the radioactivity from the column was quantitative.
↵3-c Percentages less than 1% are not reported.
↵3-d Radioactivity from peaks that have not been identified.
↵3-e Total is less than 100% because remainder of the radioactivity is distributed in small amounts (<0.5%) in various fractions throughout the radiochromatogram.
