Article Synopsis
  • Drug-induced cholestasis (DIC) is a significant concern in drug development, as it disrupts bile flow and causes toxic buildup of bile acids in the liver, representing a type of drug-induced liver injury (DILI).
  • Researchers developed a predictive model using in vitro data from 47 drugs, which distinguished between drugs with and without DILI concerns, achieving a strong predictive performance (p-value of 0.039, PR AUC of 0.91).
  • The study highlights the importance of multiple liver processes in bile acid regulation and suggests that using a quantitative model in preclinical stages can improve drug safety and reduce failures in later development stages.

Machine learning (ML) models have become key in decision-making for many disciplines, including drug discovery and medicinal chemistry. ML models are generally evaluated prior to their usage in high-stakes decisions, such as compound synthesis or experimental testing. However, no ML model is robust or predictive in all real-world scenarios.

Pathogenesis-related-10 (PR10) proteins play significant roles in plant defence against biotic and abiotic stresses. Recently, two banana PR10 proteins (MaPR10-BeB5 and MaPR10-GNA5) were characterised and shown to exhibit antifungal properties against . In rice, transgenic overexpression of PR10 proteins conferred resistance to pathogen infection and drought tolerance without affecting productivity, highlighting their potential for agricultural applications.

After initial triaging using in vitro absorption, distribution, metabolism, and excretion (ADME) assays, pharmacokinetic (PK) studies are the first application of promising drug candidates in living mammals. Preclinical PK studies characterize the evolution of the compound's concentration over time, typically in rodents' blood or plasma. From this concentration-time (-) profiles, PK parameters such as total exposure or maximum concentration can be subsequently derived.
