A Streamlined High Performance Liquid Chromatography with Tandem Mass Spectrometry Based Workflow for Rapid Screening of Cellular Accumulation of Small Molecules

open access: yesChemMedChem, EarlyView.
This study uses six small‐molecule inhibitors to evaluate optimal cellular accumulation assay conditions in a 96‐well format with high performance liquid chromatography with tandem mass spectrometry detection. The obtained medium to high‐throughput workflow is suitable for reliably identifying cellular accumulation, valuable for preclinical selection ...

Pharmacokinetic Evaluation of a Cinnamon Product on CYP2A6 Substrate Drugs: Application of a Novel Tool Involving the Nicotine Metabolite Ratio

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Cinnamon (Cinnamomum spp.) is used as a culinary spice and dietary supplement. A major constituent, cinnamaldehyde, was previously shown to inactivate cytochrome P450 (CYP) 2A6 in vitro. A mechanistic static model predicted an ~5‐fold increase in the AUC of the CYP2A6 substrates nicotine and letrozole.

The endocannabinoid system regulates both ependymoglial and neuronal cell responses to a tail amputation in the axolotl

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The endocannabinoid system is a neuromodulatory system implicated in cellular processes during both development and regeneration. The Mexican axolotl, one of only a few vertebrates capable of central nervous system regeneration, was used to examine the role of the endocannabinoid system in the regeneration of the tail and spinal ...
