Application of Process 3.4. Application of Process 3 male subjects received a single dose of 30 mg PQ. The plasma profile of PQ is Three male subjects received a single dose of 30 mg PQ. The plasma profile of PQ is shown in Figure three. All plasma concentrations have been above LLOQ and within the calibration shown in Figure three. All plasma concentrations had been above LLOQ and inside the calibration curve variety for the assay. On the other hand, five,6-PQ was Akt1 manufacturer undetectable in plasma samples. The curve range for the assay. Nonetheless, five,6-PQ was undetectable in plasma samples. The urine urine profiles of PQ and 5,6-PQ are shown in Figures 4 and 5, respectively. The pharmaprofiles of PQ and five,6-PQ are shown in Figures four and five, respectively. The pharmacokinetic cokinetic parameters in human plasma and urine are shown in Tables three and 4, respecparameters in human plasma and urine are shown in Tables 3 and 4, respectively. tively.Plasma PQ concentration (ng/mL)200 HDAC4 Biological Activity subject-1 subject-2 subject-30 0 five ten 15 20 25 Time soon after PQ dosing (h)Figure 3.
