Thermal investigation of NbSe nanoparticles synthesized through a temperature-dependent sonochemical method.

Due to their unique size-dependent properties, transition metal di-chalcogenide nanoparticles are trending in research for their potential to revolutionize next-generation electronics, energy storage, and catalytic processes. This study addresses the effect of temperature when synthesizing NbSe nanoparticles the sonochemical method at three different temperatures, room temperature (R.T.

A discovery biotransformation strategy: combining tools with high-resolution mass spectrometry and software-assisted data analysis for high-throughput metabolism.

Understanding compound metabolism in early drug discovery aids medicinal chemistry in designing molecules with improved safety and ADME properties. While advancements in metabolite prediction brings increased confidence, structural decisions require experimental data. metabolism studies using liquid chromatography and high-resolution mass spectrometry (LC-MS) are generally resource intensive and performed on very few compounds, limiting the chemical space that can be examined.

Disposition and metabolism of darapladib, a lipoprotein-associated phospholipase A2 inhibitor, in humans.

The absorption, metabolism, and excretion of darapladib, a novel inhibitor of lipoprotein-associated phospholipase A2, was investigated in healthy male subjects using [(14)C]-radiolabeled material in a bespoke study design. Disposition of darapladib was compared following single i.v.

Evaluation of a chimeric (uPA+/+)/SCID mouse model with a humanized liver for prediction of human metabolism.

A model that predicts human metabolism and disposition of drug candidates would be of value in early drug development. In this study, a chimeric (uPA+/+)/SCID mouse model was evaluated with three structurally distinct compounds (GW695634, a benzophenone, SB-406725, a tetrahydroisoquinoline and GW823093, a fluoropyrrolidine) for which human metabolism and disposition was characterized. Human metabolite profiles in plasma and/or urine were compared to those of chimeric (uPA+/+)/SCID and control CD-1 or (uPA+/+)/SCID) mice.
