Fig. 3From: Human liver microsomes study on the inhibitory effect of plantainoside D on the activity of cytochrome P450 activityInhibition model fitted with Lineweaver–Burk and Dixon plots. A The inhibition of CYP3A was best fitted with the non-competitive inhibition model and the Ki value was obtained as 7.16 μM according to the Dixon plot. B-C The inhibition of CYP1A2 (B) and CYP2D6 (C) was best fitted with the competitive inhibition model with the Ki values of 6.26 and 4.54 μM, respectively, according to the results of Dixon plotsBack to article page
