↵ a Results obtained by HPLC with a β-RAM radiometric detector. Percentages represent mean relative amount of conjugative metabolites M1, Mb, and Mc formed in microsomal incubations (n = 2 for each species) using 10 μM motesanib and 1 mg/ml microsomal protein incubated in the presence of cofactor (2 mM) at 37°C for 30 min.
