Cytochrome P450 (CYP) enzymes are responsible for the metabolism of many exogenous and endogenous compounds. CYPs are abundant in the liver and are also expressed in many extra-hepatic tissues including the brain. Although total CYP levels in the brain are much lower than in the liver, brain CYPs are concentrated near drug targets in specific regions and cell types, and can potentially have a considerable impact on local metabolism. Individual differences in brain CYP metabolism, due to inducers, inhibitors or genetic variation, can influence sensitivity and response to centrally acting drugs. Brain CYPs may also play a role in modulating brain activity, behavior, susceptibility to central nervous system diseases and treatment outcomes. This review highlights recent progress that has been made in understanding the functional significance of CYPs in the brain.

Global warming causes the release of dioxin-like deposits and increases geographical migration, increasing the risk of exposure for humans and animals. In this experiment, we used CYP1A transgenic zebrafish Tg (cyp1a: mCherry) and liver fluorescent transgenic zebrafish Tg (fabp10: Ps Red) as an animal model and exposed to 2,3,7,8-Tetrachlorodibenzo-p-Dioxin (TCDD) at 26 °C and 30 °C, respectively. Morphological changes, histological changes, transcriptome and related genes expression were detected.

HD561, which was designed to enhance nerve growth, was re-engineered into HD56, a carboxylic acid ester prodrug. The goal of this study was to compare the druggability, species differences, and the correlation between in vitro and in vivo transformation of HD56 to HD561 from a pharmacokinetic (PK) perspective, offering a scientific basis for HD56's clinical research. The bidirectional transmembrane transport of HD56 and HD561 was investigated using Caco-2 cells and LLC-PK1 cells overexpressing MDR1 monolayer cells.

Apnea is a major complication of acute respiratory tract infection in young infants and may lead to the need for ventilatory support. Caffeine is methylxanthine, which is considered the mainstay of pharmacologic treatment for apnea of prematurity. On the basis of neonatal guidelines, caffeine has been used as a respiratory stimulant for the treatment of acute respiratory tract infection-related apnea, despite low evidence of its ability to improve clinical outcomes.

Background: In major depressive disorder (MDD), only ~35% achieve remission after first-line antidepressant therapy. Using UK Biobank data, we identify sociodemographic, clinical, and genetic predictors of antidepressant response through self-reported outcomes, aiming to inform personalized treatment strategies.
Methods: In UK Biobank Mental Health Questionnaire 2, participants with MDD reported whether specific antidepressants helped them.

-Anethole (1-methoxy-4-[1()-propenyl]benzene, tAT) is the main ingredient in the essential oil extracted from star anise fruits. The double bonds in the side chain of tAT are a type of alert structure that can be metabolized into epoxides possibly causing liver damage. This work investigated and identified the reactive metabolites of tAT that are chemically reactive to biothiols, such glutathione (GSH), -acetyl-l-cysteine (NAC), and cysteine residues of proteins.
