5-O-Desmethyl Omeprazole-d3

5-O-Desmethyl Omeprazole-d3 is a deuterated form of the proton pump inhibitor drug Omeprazole. This compound is used in pharmacokinetic research and clinical studies to investigate the metabolism and elimination of Omeprazole in the human body. The chemical structure of 5-O-Desmethyl Omeprazole-d3 contains three deuterium atoms at specific positions in the molecule, which allows for accurate quantification and identification of metabolites of Omeprazole in biological samples. Omeprazole belongs to the class of drugs known as proton pump inhibitors, which work by inhibiting the activity of the H+/K+ ATPase enzyme in the stomach lining. This enzyme is responsible for producing acid in the stomach, and its inhibition leads to reduced acid secretion and relief of symptoms associated with acid-related disorders such as gastroesophageal reflux disease and peptic ulcers. 5-O-Desmethyl Omeprazole-d3 is metabolized in the liver by the cytochrome P450 enzyme system, primarily by the CYP2C19 enzyme, into various metabolites that are excreted in the urine and feces. The deuterium-labeled compound is useful in determining the extent of metabolism and clearance of Omeprazole and its metabolites in different populations, such as individuals with genetic variations in the CYP2C19 enzyme. In summary, 5-O-Desmethyl Omeprazole-d3 is a valuable tool in pharmacokinetic and clinical research for understanding the metabolism and elimination of Omeprazole in the human body.
