1750-45-4, In heterogeneous catalysis, the catalyst is in a different phase from the reactants. At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 1750-45-4, name is 5-Chloro-6-hydroxybenzo[d]oxazol-2(3H)-one. In an article£¬Which mentioned a new discovery about 1750-45-4
Comprehensive kinetic analysis and influence of reaction components for chlorzoxazone 6-hydroxylation in human liver microsomes with CYP antibodies
1. Chlorzoxazone (CLZ) is currently being used as a marker substrate in vitro/vivo studies to quantify cytochrome P450 2E1 (CYP2E1) activity in humans. Although in CLZ 6-hydroxylation several CYPs are responsible, previous studies have presented the monophasicity of the reaction in human liver microsomes (HLMs). Furthermore, the Km values of CYP2E1 for the 6-hydroxylation in HLMs were reported to be lower than those of its recombinant enzymes. 2. This study aimed to provide the comprehensive Km values for the CLZ 6-hydroxylation in HLMs using CYP antibodies. The Eadie-Hofstee plots revealed a biphasic profile and indicate that the reaction was mainly mediated by CYP1A2 as well as CYP2E1. The formation of 6-hydroxychlorzoxazone was more specific for CYP2E1 activity at higher substrate concentration in HLMs. 3. Moreover, KOH as a vehicle for substrate or sucrose included in HLMs preparation had some effect on the activity of CLZ 6-hydroxylase. These constituents seemed to be casually related to the apparent monophasic kinetics and variability in Km values for the CLZ 6-hydroxylation in HLMs. 4. The Km of CYP1A2 and CYP2E1 in HLMs was 3.8 mumol/L and 410 mumol/L, respectively, and the value of CYP2E1 was close to that of recombinant CYP2E1.
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 1750-45-4 is helpful to your research. 1750-45-4
