Borneol is a traditional Chinese medicine. In the past few years, many studies showed that borneol can improve the bioavailability of other drugs, promoting drugs to cross the blood-brain barrier, so the potential drug interactions between borneol and other medicines have attracted great attention, but the influence of borneol to CYP450 and its isoforms are rarely reported. In this research, male Wistar rats were orally administered by borneol for 7 days, then the mRNA and protein expression and the activities of CYP2D were detected, we also compared the pharmacokinetic parameters of CYP2D's specific substrate between control group and borneol group. The results show that borneol (33, 100 and 300 mg x kg(-1) x d(-1)) have no significant effect on CYP2D, while the activites of CYP2D increased 1.71, 1.97 and 2.89 times comparing to the control group. At the same time, borneol (300 mg x kg(-1) x d(-1)) caused the C(max) decreased 10.6% (P > 0.05), AUC(0-∞) decreased 27.5% (P < 0.01), CL/F increased 41.1% (P < 0.01), V(z)/F increased 23.1% (P > 0.05) of dextromethorphan. Our data provided that borneol speed up dextromethorphan's elimination in vivo. Since the activity of CYP2D can be induced by borneol, the metabolic interactions might happen when borneol and the substrate drug CYP2D are used together.

To study the effects of major components of Maijunan tablets, puerarin (Pue) and rhynchophylline (Rhy) on the transport of hydrochlorothiazide (Hct) Caco-2 cell monolayer model, the transport parameters of Hct, such as apparent permeability coefficient (P(app) (B --> A) and P(app) (A --> B)) and the ratio of P(app) (B --> A) versus P(app) (A --> B), were studied and compared when Hct was used solely and co-used with Pue and/or Rhy. The effects of drug concentrations, conveying times, P-glyprotein (P-gp) inhibitor verapamil and conveying Liq pH values on the transport of Hct in the above conditions were also investigated. The results indicated that the absorption of Hct in Caco-2 cell monolayer model could be a carrier-mediated active transport, along with the excretion action mediated by P-gp. Pue can decrease the excretion action of Hct mediated by P-gp, and Rhy had no significant effect on the transport of Hct. The co-use of Hct, Pue and Rhy enhanced the absorption of Hct. Meanwhile, conveying Liq pH value had significant influence on the transport of Hct. The absorption of Hct at pH 6.0 was higher than that at pH 7.4.

The effects of magnolol (Mag) on hyperglycemia and hyperlipemia, hepatic oxidative stress and cytochrome P4502E1 (CYP2E1) activity of diabetic rats induced by high-fat diet (HFD) and streptozotocin (STZ) were studied. After oral administration of Mag (25, 50 and 100 mg x kg(-1) x d(-1)) for continuous 10 weeks, the blood glucose and lipids (TC, TG and LDL-C) levels, as well as the hepatic CYP2E1 activity and MDA content of diabetic rats, decreased significantly (P < 0.05 or P < 0.01), whereas the oral glucose tolerance and hepatic antioxidant enzymatic activities (CAT and GSH-Px) of diabetic rats, increased significantly (P < 0.05 or P < 0.01). The results indicated that Mag was effective against the hepatic oxidative damage, hyperglycemia and hyperlipemia of diabetic rats induced by HFD and STZ, and the inhibition of Mag on hepatic CYP2E1 activity could be an important mechanism of Mag against hepatic insulin resistance and oxidative damage.
