One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Formula: C8H6N2, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 253-52-1, Name is Phthalazine, molecular formula is C8H6N2
Inhibition of human liver aldehyde oxidase: Implications for potential drug-drug interactions
During the course of our research efforts to understand the kinetics of human aldehyde oxidase as a xenobiotic-clearing enzyme, we investigated the effect of eight different inhibitors on the oxidation of the probe substrate phthalazine. Saturation kinetic parameters for phthalazine oxidation in human liver cytosol were found to be the following: Km = 8.0 ¡À 0.4 muM and Vmax = 4.3 ¡À 0.1 nmol¡¤min -1¡¤mg protein-1. Inhibitory potency of the inhibitors tested ranged from 0.1 to 5 muM. Of the eight different inhibitor compounds tested, seven were observed to inhibit through a mixed mode and one through a strictly competitive mode. A ratio of the Kii and K is values was used to assess the relative competitiveness of each inhibitor. For the mixed inhibitors, the mode of inhibition varied from mostly uncompetitive to predominantly competitive (Kii/Kis values ranging from 0.1 to 15). The implications for potential drug-drug interactions and inhibition mechanism are discussed. We found two inhibitors, clozapine and chlorpromazine, that have a moderate predicted risk of drug-drug interactions based on the Ki value relative to the inhibitor concentration in human plasma, having a calculated [I]/Ki value of 0.4 and 0.8, respectively.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Formula: C8H6N2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 253-52-1, in my other articles.
