AUC values (mean ± S.D., n = 3) were determined by the trapezoidal rule using Prism software. PAS or SMZ (50 mg/kg) was dosed by i.p. injection to age- and sex-matched wild-type and knockout mice. Four sequential blood samples were drawn and analyzed for parent and metabolite compounds as described under Materials and Methods.
