Progress in the synthesis of 2-aminobenzoxazole derivatives

2-Aminobenzoxazole derivatives are a kind of heterocyclic compounds, which play important roles in medicine, biology and material science, and their synthetic methods have attracted much attention. In recent years, many efficient, green synthetic approaches of 2-aminobenzoxazole derivatives using transition-metal or metal-free catalytic systems have been reported. Based on differences of reaction substrates and synthetic methods, the recent advances in the synthesis of 2-aminobenzoxazole derivatives are reviewed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 4570-41-6, you can also check out more blogs about4570-41-6

Obesity-induced increase of CYP2E1 activity and its effect on disposition kinetics of chlorzoxazone in Zucker rats

This study was designed to investigate the induction of CYP2E1 in obese Zucker rats and its effect on the disposition kinetics of chlorzoxazone (CZX). CZX 20 mg/kg was administered to three groups of rats: normal Zucker rats fed a normal diet (ND), normal Zucker rats fed a high-fat diet (HF), and genetically obese Zucker rats fed a normal diet (OB). The values of the area under the plasma concentration-time curve from 0 to ? (AUC?) of CZX were in the order of ND > HF > OB rats. The AUC? values of total 6-hydroxychlorzoxazone (6OHCZX-T), which is considered to be a CYP2E1 metabolic marker, were in the opposite order. The values of the AUC? ratio (6OHCZX-T/CZX) in ND, HF and OB rats were approximately 0.2, 0.3 and 0.4, respectively. The CZX concentration in fat was much higher than the concentrations in plasma, liver and kidney in all groups. Induction of CYP2E1 protein was greater in both liver and fat of OB rats than in those of HF rats. Microsomal activity of CYP2E1 in liver and fat was also in the order of OB > HF > NM rats. These results suggest that CYP2E1 may be induced in liver and fat of obese patients, thereby potentially altering the disposition kinetics of not only CZX, but also other lipophilic drugs metabolized by CYP2E1.
