In vitro inhibitory effects of bergenin on human liver cytochrome p450 enzymes

Context: Bergenin, isolated from the herb of Bergenia purpurascens (Hook. f. et Thoms.) Engl., has anti-inflammatory, antitussive, and wound healing activities. However, whether bergenin affects the activity of human liver cytochrome P450 (CYP) enzymes remains unclear. Materials and methods: In this study, the inhibitory effects of bergenin (100 lM) on the eight human liver CYP isoforms (i.e., 1A2, 3A4, 2A6, 2E1, 2D6, 2C9, 2C19 and 2C8) were investigated, enzyme kinetics and time-dependent inhibition studies were also performed in vitro using human liver microsomes (HLMs). Results: The results showed that bergenin inhibited the activity of CYP3A4, 2E1 and 2C9, with IC50 values of 14.39, 22.83 and 15.11 lM, respectively, but other CYP isoforms were not affected. Enzyme kinetic studies showed that bergenin was not only a non-competitive inhibitor of CYP3A4, but also a competitive inhibitor of CYP2E1 and 2C9, with Ki values of 7.71, 11.39 and 8.89 lM, respectively. In addition, bergenin is a time-dependent inhibitor for CYP3A4 with Kinact/KI value of 0.025/3.50 lM1 min1. Discussion and conclusions: The in vitro studies of bergenin with CYP isoforms indicate that bergenin has the potential to cause pharmacokinetic drug interactions with other co-administered drugs metabolized by CYP3A4, 2E1 and 2C9. Further clinical studies are needed to evaluate the significance of this interaction.

Inhibitory effects of sanguinarine on human liver cytochrome P450 enzymes

Sanguinarine (SAG) has been recognized as an anticancer drug candidate. However, the drug-drug interactions (DDI) potential for SAG via the inhibition against human cytochrome P450 (CYP) enzymes remains unclear. In the present study, the inhibitory effects of SAG on seven major human CYP isoforms 1A2, 2A6, 2E1, 2D6, 2C8, 2C9 and 3A4 were investigated with human liver microsomes (HLM). The results showed that SAG was a potent noncompetitive inhibitor of CYP2C8 activity (Ki=8.9muM), and competitive inhibitor of CYP1A2, CYP2C9 and CYP3A4 activities (Ki=2.7, 3.8 and 2.0muM, respectively). Furthermore, SAG exhibited time- and NADPH-dependent inhibition towards CYP1A2 and CYP3A4 with KI/kinact values of 13.3/0.087 and 5.58/0.029min-1muM-1, respectively. Weak inhibition of SAG against CYP2E1, CYP2D6 and CYP2A6 was also observed. In vitro-in vivo extrapolation (IV-IVE) from HLM data showed that more than 35.9% of CYP1A2, CYP2C9, CYP2C8 and CYP3A4 activities in vivo could be inhibited by SAG, suggesting that harmful DDIs could occur when SAG or its medical preparations are co-administered with drugs primarily cleared by these CYP isoforms. Further in vivo studies are needed to evaluate the clinical significance of the data presented herein.

Electrogenerated Cationic Reactive Intermediates: The Pool Method and Further Advances

Electrochemistry serves as a powerful method for generating reactive intermediates, such as organic cations. In general, there are two ways to use reactive intermediates for chemical reactions: (1) generation in the presence of a reaction partner and (2) generation in the absence of a reaction partner with accumulation in solution as a “pool” followed by reaction with a subsequently added reaction partner. The former approach is more popular because reactive intermediates are usually short-lived transient species, but the latter method is more flexible and versatile. This review focuses on the latter approach and provides a concise overview of the current methods for the generation and accumulation of cationic reactive intermediates as a pool using modern techniques of electrochemistry and their reactions with subsequently added nucleophilic reaction partners.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4570-41-6 is helpful to your research. 4570-41-6

Evaluation of the inhibition effects of apatinib on human and rat cytochrome P450

Apatinib, a small molecule anti-angiogenic drug, is proven to be safe and effective for treatment of advanced gastric cancer (AGC). It is also a single drug that significantly prolongs survival after failure of standard chemotherapy for AGC, which has attracted the research interest. The purpose of this study is to evaluate the inhibition effects of apatinib on human and rat cytochrome P450, including CYP3A2/4, CYP2B1/6, CYP2C9/11, CYP2D1/6, and CYP2E1. The IC50 and IC50-shift results indicated that apatinib might not be a time-dependent inhibitor. Apatinib was a weak inhibitor of human CYP2E1 (IC50>10 muM) but inhibited CYP2B6/2B1 and CYP2D6/2D1 in a competitive way (Ki = 3.84/0.59 and 5.41/0.87 muM), and inhibited CYP3A4/3A2 and rat CYP2E1 in a mixed way (Ki = 11.50/1.83 and 13.06 muM). On CYP2C9, apatinb exhibited the noncompetitive inhibition (Ki = 0.71 muM) while it inhibited CYP2C11 uncompetitively (Ki = 3.30 muM).

Synthesis of 2-(2,3-Dihydro-2-oxo-1,3,4-oxadiazolyl-5-yl) Benzo Heterocycles. A Novel Series of Orally Active Antiallergic Agents

A series of new 2-(2,3-dihydro-2-oxo-1,3,4-oxadiazol-5-yl) benzo heterocycles has been prepared.These compounds were tested as inhibitors of antigen-induced release of histamine (AIR) in vitro from rat peritoneal mast cells (RMC) and as inhibitors of IgE-mediated rat passive cutaneous anaphylaxis in the rat (PCA).Most of this new class of antiallergic agents showed good activity in the RMC assay.The most potent compound, 3-chloro-2-(2,3-dihydro-2-oxo-1,3,4-oxadiazol-5-yl)benzothiophene (6t), with an I50 value of 0.2 muM, is 15 times more potent than disodium cromoglycate (DSCG) in the RMC assay.Many compounds were orally active in the PCA test, and several of these compounds showed higher potency when given in this way to that shown by DSCG when given intraperitoneally.
