Development of an LC-MS/MS method to quantitatively analyze escitalopram and its metabolites with application in liver and placenta microsome metabolism

open access: yesFrontiers in Pharmacology
BackgroundEscitalopram (SCT), a highly effective and low-risk antidepressant, is widely used in the clinical treatment of depression. It undergoes two N-demethylation steps, producing its primary metabolites, S-demethylcitalopram (S-DCT) and S ...

CYP-Dependent Metabolism of PF9601N, A New Monoamine Oxidase-B Inhibitor, by C57BL / 6 Mouse and Human Liver Microsomes

open access: yesJournal of Pharmacy & Pharmaceutical Sciences, 2007
Purpose. The selective monoamine oxidase-B (MAO-B) inhibitor, l-deprenyl, is still used for treating Parkinson's patients, however, a disadvantage of its use lies in the formation of l-amphetamine and l-methamphetamine.

Exchange of phospholipid classes between liver microsomes and plasma: comparison of rat, rabbit, and guinea pig

open access: yesJournal of Lipid Research, 1971
Rat and guinea pig liver microsomes labeled with phospholipid 32P were incubated with rat, guinea pig, and rabbit plasma in a KC1–Tris–EDTA buffer. A net transfer of microsomal phosphatidylcholine and phosphatidylethanolamine to plasma was observed.

Analysis of in vitro and in vivo metabolism of zidovudine and gemfibrozil in trans‐chromosomic mouse line expressing human UGT2 enzymes

open access: yesPharmacology Research & Perspectives, 2022
UDP‐glucuronosyltransferases (UGTs) catalyze the conjugation of various substrates with sugars. Since the UGT2 family forms a large cluster spanning 1.5 Mb, transgenic mouse lines carrying the entire human UGT2 family have not been constructed because of
