Changes of microsomal membrane compositions modulate microsomal enzyme activity [PDF]
Pediatric Research, 1979 We have shown previously, that the activity of cerebrosulfotransferase (CST) a microsomal enzyme involved in myelin synthesis is modulated in vitro by the cholesterol-phospholipid ratio (C/P) in microsomal membranes. To further investigate this mechanism, we studied two different models: 1.) Removal of cholesterol by phospholipid micelles and 2 ...

GC–MS analysis of oxysterols and their formation in cultivated liver cells (HepG2)
Lipids, Volume 58, Issue 1, Page 41-56, January 2023., 2023 Abstract Oxysterols play a key role in many (patho)physiological processes and they are potential biomarkers for oxidative stress in several diseases. Here we developed a rapid gas chromatographic‐mass spectrometry‐based method for the separation and quantification of 11 biologically relevant oxysterols bearing hydroxy, epoxy, and dihydroxy groups ...

Analyses of CYP2C in Porcine Microsomes [PDF]
Basic & Clinical Pharmacology & Toxicology, 2008 Abstract: The cytochrome P450 2C (CYP2C) subfamily in human beings includes four different isoenzymes that metabolize different substrates although with some cross reactivity. Some of these substrates (e.g. diclofenac and tolbutamide), have been investigated in porcine microsomes, but without identifying the specific CYP catalysing the reactions.

Mass spectrometry in ocular drug research
Mass Spectrometry Reviews, EarlyView., 2023 Abstract Mass spectrometry (MS) has been proven as an excellent tool in ocular drug research allowing analyzes from small samples and low concentrations. This review begins with a short introduction to eye physiology and ocular pharmacokinetics and the relevance of advancing ophthalmic treatments.

Metabolism and Metabolic Inhibition of Xanthotoxol in Human Liver Microsomes [PDF]
, 2016 Cytochrome p450 (CYP450) enzymes are predominantly involved in Phase I metabolism of xenobiotics. In this study, the CYP450 isoforms involved in xanthotoxol metabolism were identified using recombinant CYP450s.

Part Two: Evaluation of N-methylbupropion as a Potential Bupropion Prodrug
Pharmaceuticals, 2014 N-methylbupropion was selected as a potential prodrug from our in vitro screening of analogues of bupropion described in the preceding paper. This study describes in vivo pharmacokinetics of N-methylbupropion in the guinea-pig animal model, which is ...

Medicinal Research Reviews, Volume 43, Issue 1, Page 237-287, January 2023., 2023 Abstract The transcription factor nuclear factor erythroid 2‐related factor 2 (NRF2) is considered the master regulator of the phase II antioxidant response. It controls a plethora of cytoprotective genes related to oxidative stress, inflammation, and protein homeostasis, among other processes.

CYP52X1, representing new cytochrome P450 subfamily, displays fatty acid hydroxylase activity and contributes to virulence and growth on insect cuticular substrates in entomopathogenic fungus Beauveria bassiana [PDF]
, 2012 Infection of insects by the entomopathogenic fungus Beauveria bassiana proceeds via attachment and penetration of the host cuticle. The outermost epicuticular layer or waxy layer of the insect represents a structure rich in lipids including abundant ...
