a Mean cumulative percent of radioactive dose in urine, bile, and feces of bile-cannulated (BDC) animals (n = 3) (solid circle, urine; hollow reverse triangle, feces; solid square, bile; solid triangle, total). The mean and standard deviation (SD) are plotted with individual numerical data listed in Supplementary Table 2. b HPLC radioactivity profiles in urine, bile and feces. c Structures of 14C-A947 metabolites in urine, bile, and feces of rats.
