Effect of commonly used organic solvents on Aldehyde oxidase-mediated Vanillin, Phthalazine and Methotrexate oxidation in human, rat and mouse liver subcellular fractions
1. Aldehyde oxidase (AOX) is a cytosolic molybdoflavoprotein enzyme widely distributed across many tissues. In this study, we report the effect of commonly used organic solvents such as dimethyl sulfoxide (DMSO), acetonitrile (ACN), methanol and ethanol on AOX activity in human, rat and mouse liver S9 fractions using vanillin, phthalazine and methotrexate as probe substrates. 2. Methanol was found to be the most potent solvent in inhibiting vanillic acid and 1-phthalazinone formation in comparison to DMSO, ACN and ethanol across the species tested, except 7-hydroxy methotrexate. 3. Treatment with these solvents at approximate IC50 (% v/v) concentrations showed significant reduction in Cl-int and V-max of the probe substrates and also resulted in different effects on K-m across the species. 4. Marked differences in the activity and affinity towards AOX were observed with different probe substrates with methotrexate showing least activity and affinity as compared to vanillin and phthalazine. 5. Overall, AOX activity seemed to be more resilient to the presence of organic solvents at higher concentrations in human and rodent species. These results suggest that low concentrations of organic solvents are acceptable for in vitro incubations involving AOX-mediated metabolism.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 482-05-3, you can contact me at any time and look forward to more communication. Recommanded Product: [1,1′-Biphenyl]-2,2′-dicarboxylic acid.
