AI Article Synopsis

Article Abstract

Background: The use of liver microsomes and hepatocytes to predict total in vivo clearance is standard practice in the pharmaceutical industry; however, metabolic stability data alone cannot always predict in vivo clearance accurately.

Results: Apparent permeability generated from Mardin-Darby canine kidney cells and rat hepatocyte uptake for 33 discovery compounds were obtained.

Conclusion: When there is underprediction of in vivo clearance, compounds with low apparent permeability (less than 3 × 10(-6) cm/s) all exhibited hepatic uptake. A systematic approach in the form of a classification system (hepatic clearance classification system) and decision tree that will help drug discovery scientists understand in vitro-in vivo clearance prediction disconnect early is proposed.

Accumulating evidence demonstrates that alpha-synuclein (α-syn) pathology associated with Parkinson's disease (PD) is not limited to the brain, as it also appears in a select number of peripheral tissues including the liver. In this study, we identified a number of PD-associated α-syn post-translational modifications in the livers of (Thy-1)-h[A30P] mice, a mouse model of familial PD expressing human α-syn harboring the A30P mutation driven by a neuron-specific promoter. , we also demonstrate that human hepatocytes induce post-translational modifications following α-syn fibrillar (PFF) treatment.

A high-fat diet (HFD) induces obesity and insulin resistance, which may exacerbate amyloid-β peptide (Aβ) pathology during Alzheimer's disease (AD) progression. Branched-chain amino acids (BCAAs) accumulate in obese or insulin-resistant patients and animal models. However, roles of accumulated BCAAs and their metabolites, branched-chain keto acids (BCKAs), in the HFD-induced deterioration of AD and the underlying mechanisms remains largely unclear.

The primary objective of urolithiasis therapy is complete stone removal and highest stone-clearance rates possible to minimize recurrence. A novel approach that employs a magnetic suspension and a magnetic probe for the passive collection and removal of small residual fragments was developed. This study assessed the feasibility of this system in porcine models.
