Inhibition of UGT1A7-mediated 4-MU glucuronidation reaction by cryptotanshinone. (A) Dixon plot of inhibitory effects of cryptotanshinone towards recombinant UGT1A7-catalyzed 4-MU glucuronidation. (B) Lineweaver–Burk plot of inhibitory effects of cryptotanshinone towards recombinant UGT1A7-catalyzed 4-MU glucuronidation. (C) Second plot of slopes from Lineweaver–Burk plot versus cryptotanshinone concentrations. Every data point represents the mean of two replicates.
