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

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 ...

LIVER MICROSOMES [PDF]

open access: yesThe Journal of Cell Biology, 1956
Rat liver, liver homogenates, and microsome fractions separated therefrom were examined systematically in the electron microscope in sections of OsO4-fixed, methacrylate-embedded tissue and pellets. It was found that most microsomes are morphologically identical with the rough surfaced elements of the endoplasmic reticula of hepatic ...

The composition of rat liver microsomes. The structural proteins of rat liver microsomes [PDF]

open access: yesBiochemical Journal, 1969
1. The structural-protein component of microsomal membranes was isolated by three separate methods. Analysis by polyacrylamide-gel electrophoresis indicated that the microsomal structural component is made up of a heterogeneous group of proteins. These proteins were further characterized by their phospholipid-binding capacity.

In vitro metabolism, reaction phenotyping, enzyme kinetics, CYP inhibition and induction potential of ataluren

open access: yesPharmacology Research & Perspectives, 2020
Ataluren promotes ribosomal readthrough of premature termination codons in mRNA which result from nonsense mutations. In vitro studies were performed to characterize the metabolism and enzyme kinetics of ataluren and its interaction potential with CYP ...

3-hydroxy-3-methylglutaryl coenzyme A reductase in human liver microsomes: active and inactive forms and cross-reactivity with antibody against rat liver enzyme.

open access: yesJournal of Lipid Research, 1984
3-Hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, the enzyme catalyzing the rate-limiting step in cholesterol biosynthesis, exists in one active (dephosphorylated) and one inactive (phosphorylated) form in liver microsomes obtained from several ...

Studies on the hyperplasia ('regeneration') of the rat liver following partial hepatectomy. Changes in lipid peroxidation and general biochemical aspects [PDF]

open access: yes, 1990
Using the experimental model of partial hepatectomy in the rat, we have examined the relationship between cell division and lipid peroxidation activity. In rats entrained to a regime of 12 h light/12 h dark and with a fixed 8 h feeding period in the dark

Characterization of the metabolism of eupalinolide A and B by carboxylesterase and cytochrome P450 in human liver microsomes

open access: yesFrontiers in Pharmacology, 2023
Eupalinolide A (EA; Z-configuration) and eupalinolide B (EB; E-configuration) are bioactive cis-trans isomers isolated from Eupatorii Lindleyani Herba that exert anti-inflammatory and antitumor effects.
