The parent compound and metabolites obtained from in vitro and in vivo samples were determined by LC/MS. The main metabolite was isolated and identified as an N-oxide form of CKD-732 by NMR and LC/MS/MS. CKD-732 was metabolized into either M11 or others by rapid hydroxylation, demethylation, and hydrolysis. The blood level following the intravenous route declined in first-order kinetics with T(1/2)beta values of 0.72similar to0.78 h for CKD-732 and 0.92similar to1.09 h for M11 in rats at a dose of 7.5similar to30 mg/kg. In dogs, T1/20 values of CKD-732 and M11 were 1.54 and 1.79 h, respectively. Moreover, AUC values increased dose dependently for CKD-732 and M11 in rats and dogs. The CLtot and Vdss did not change significantly with increasing dose, indicating linear pharmacokinetic patterns. The excretion patterns through the urine, bile, and feces were also examined in the animals. The total amount excreted in urine, bile, and feces was 2.13% for CKD-732 and 1.29% for M11 in rats, and 1.58% for CKD-732 and 2.28% for M11 in dogs.
