Inhibitory Effects of Daiokanzoto (Da-Huang-Gan-Cao-Tang) on P-Glycoprotein

Figure 6

Lineweaver-Burk (a) and Dixon (b) plots for the inhibitory effects of rhubarb on ATPase activity in the presence of verapamil. (a) The final concentration of rhubarb was 0 (●), 0.0625 (○), 0.25 (▲), or 0.5 ( Δ ) mg/mL. (B) The final concentration of verapamil was 1.56 (●), 3.13 (○), 6.25 (▲), 12.5 ( Δ ), 25 (■), or 50 (□) 𝜇 M. Data represent the mean ± SD of three experiments. 𝑉 : ATPase activity (nmol/mg protein/min), 𝑆 : verapamil concentration ( 𝜇 M).
