It contains the necessary enzymes for metabolism of drugs and other xenobiotics. These enzymes induce two metabolism pathways: Phase I (functionalization reactions). The enzymes involved in Phase I reactions are primarily located in the endoplasmic reticulum of the liver cell, they are called ...
Finally, it is possible that certain compounds are active in only one cell line due to metabolism or other cell-specific properties, and further testing is required to determine their suitability for downstream drug development.Based on our prioritization, we tested activity of representative hits ...
The main regulator of cellular stress is PKM2, a key enzyme in glycolysis [63] that promotes reductive glutamine metabolism [61]. PKM2 knockout in healthy HSCs has shown no substantial defect minus loss of reconstitution potential observed upon multiple serial transplants. Additionally, PKM2 knockou...
other tissue components. Reducing the concentration of free solute causes a decrease in the rate of passage across membrane barriers and may alter drug distribution at equilibrium, as reflected in Vddeterminations. Drug sequestration can also affect the processes of absorption, metabolism, and ...
RD-V (Rabeprazole) has been shown to inhibit cyclosporine metabolism in vitro (7.3) RD-V (Rabeprazole) inhibits gastric acid secretion and may interfere with the absorption of drugs where gastric pH is an important determinant of bioavailability (e.g., ketoconazole, iron salts and digoxin) (7.4...
On the other hand, there are other excipients, such as stabilisers, preservatives, flavours, colours, etc., that, due to their composition or metabolism, could generate uncertainty for patients, caregivers or health care professionals regarding their possible administration in HFI patients. In this ...
Abnormalities in fatty acid metabolism have been associated with neurodevelopmental disorders. Fatty acids levels have been shown to be dysregulated in autistic children [65]. In addition, fatty acids exert a stimulatory action on the dopamine D2 receptor, implying a potential mechanism for sulpiride ...

Phase I reactions are usually rate-limiting in drug metabolism. Prior exposure to the compound, or other compounds, can induce the expression of Phase I enzymes however, and thereby increase substrate flux through the metabolic pathways. (See Klaassen, C. D., Amdur, M. O. and J. Doull (...
