Effects of catalpol on the activity of human liver cytochrome P450 enzymes

1. Catalpol possesses numerous pharmacological activities, and however, little data available for the effects of catalpol on the activity of human liver cytochrome P450 (CYP) enzymes. 2. This study investigates the inhibitory effects of catalpol on the main human liver CYP isoforms. In this study, the inhibitory effects of catalpol on the eight human liver CYP isoforms 1A2, 2A6, 2E1, 2D6, 2C9, 2C19, 2C8 and 3A4 were investigated in human liver microsomes. 3. The results indicated that catalpol could inhibit the activity of CYP3A4, CYP2E1 and CYP2C9, with IC50 values of 14.27, 22.4 and 14.69 muM, respectively, but those other CYP isoforms were not affected. Enzyme kinetic studies showed that catalpol was not only a noncompetitive inhibitor of CYP3A4, but also a competitive inhibitor of CYP2E1 and CYP2C9, with Ki values of 7.40, 10.75 and 7.37 muM, respectively. In addition, catalpol is a time-dependent inhibitor for CYP3A4, with maximum inactivation (kinact) and 50% maximum inactivation (KI) values of 0.02 min?1 and 1.86 muM, respectively. 4. The in vitro studies of catalpol with CYP isoforms suggest that catalpol has the potential to cause pharmacokinetic drug interactions with other co-administered drugs metabolized by CYP3A4, CYP2E1 and CYP2C9. Further in vivo studies are needed in order to evaluate the significance of this interaction.

Effects of ammonium phosphate on the formation of crystal copper sulfide on chrysocolla surfaces and its response to flotation

In this study, for the first time, we applied ammonium phosphate to pre-treat chrysocolla prior to sulfidization flotation. In addition, we investigated the structural characteristics of the copper sulfide film formed on the chrysocolla surfaces and its response to flotation. Micro-flotation experiments revealed that the addition of (NH4)3PO4 prior to sulfidization greatly improves the floatability of chrysocolla and its recovery increased from 8.71% to 87.97% with butyl xanthate as the collector. The results of the field emission scanning electron microscopy analysis showed that numerous regular fragments appeared on the chrysocolla surfaces after the addition of (NH4)3PO4. The X-ray diffraction and X-ray photoelectron spectrometry analysis confirmed that these fragments were newly formed copper sulfide covering the chrysocolla surfaces, during this process a chemical reaction occurred in the slurry system, i.e. the Cu2+ were reduced to Cu+, the S2? were mainly oxidized to S?, (S2)?, (S2)2?. The copper sulfide species primarily in the form of crystalline covellite (Cu+ 3(S2)2?S?), which is the key to obtaining good flotation recovery. As a specific activator, (NH4)3PO4 participates in the liquid-solid phase chemical reaction between the sulfidizing reagent and the chrysocolla, which promotes the sulfidization reaction of chrysocolla.

Design, synthesis, and biological evaluation of N,N-disubstituted-4-arylthiazole-2-methylamine derivatives as cholesteryl ester transfer inhibitors

Cholesteryl ester transfer protein (CETP) has been identified as a potential target for cardiovascular disease (CVD) for its important role in the reverse cholesteryl transfer (RCT) process. In our previous work, compound 5 was discovered as a moderate CETP inhibitor. The replacement of the amide linker by heterocyclic aromatics and then a series of N,N-substituted-4-arylthiazole-2-methylamine derivatives were designed by utilizing a conformational restriction strategy. Thirty-six compounds were synthesized and evaluated for their CETP inhibitory activities. Structure-activity relationship studies indicate that electron donor groups substituted ring A, and electron-withdrawing groups at the 4-position of ring B were critical for potency. Among these compounds, compound 30 exhibited excellent CETP inhibitory activity (IC50 = 0.79 ¡À 0.02 muM) in vitro and showed an acceptable metabolic stability.

Hepatic expression of cytochrome P450 in Zucker diabetic fatty rats

In this study, the hepatic expression of cytochrome P450 (CYP) enzymes, including CYP1A1/2, 2B1, 2C11, 2E1, 3A1/2, and 4A, was investigated in 5-week-old (insulinresistant state) and 11-week-old (diabetic) Zucker diabetic fatty (ZDF) rats. Serum glucose and glycated hemoglobin levels were increased in 11-week-old ZDF rats, but not in 5-weekold ZDF rats. Hyperinsulinemia was observed in both age groups. The microsomal protein, total CYP, CYP reductase, CYP1A1/2, and CYP3A1 levels did not differ between 5- and 11-week-old ZDF rats and their respective control rats, while CYP4A was up-regulated in both groups. Hepatic levels of cytochrome b5, CYP2B1, CYP2C11, CYP2E1, and CYP3A2 were decreased in 5-week-old ZDF rats, but not in 11-week-old ZDF rats. Similarly, pentoxyresorufin O-depentylase, testosterone 2alpha- and 16alpha-hydroxylase, chlorzoxazone 6- hydroxylase, and midazolam 1?- and 4-hydroxylase activities were decreased only in 5-weekold ZDF rats. Based on these results, the 5-week-old ZDF rats exhibited down-regulation of the major CYP enzymes. These results suggest that hepatic expression of CYP enzymes may be dysregulated during development in ZDF rats. With the exception of CYP2B1 and CYP4A, the hepatic levels and activities of CYP were comparable between 11-week-old ZDF and control rats, suggesting that xenobiotic metabolism is normally regulated in the early diabetic state.
