Analytical chemistry
Developing a sensitive analytical platform for monitoring tiopronin (MPG), its metabolite 2-mercaptopropionic acid (MPA), and the key liver biomarker glutathione (GSH) is crucial for liver health assessment. Here, an artificial intelligence-assisted ...

Insights into ionic liquid-enhanced membrane protein stability through machine learning and molecular simulations.

Physical chemistry chemical physics : PCCP
Protein stability plays a critical role in structural elucidation, enzyme activity, and the storage of protein drugs, where ionic liquids (ILs) have emerged as promising protein stabilizers due to their exceptional biocompatibility and superior solub...

AQuaRef: machine learning accelerated quantum refinement of protein structures.

Nature communications
Cryo-EM and X-ray crystallography provide crucial experimental data for obtaining atomic-detail models of biomacromolecules. Refining these models relies on library-based stereochemical data, which, in addition to being limited to known chemical enti...

Understanding the Role of Noncovalent Interactions in Gas Sensing with Metal-Coordinated Complexes (MCCs).

Topics in current chemistry (Cham)
Gas sensing is vital for environmental monitoring, safety, and healthcare. This review highlights the role of noncovalent interactions, hydrogen bonding, π-π stacking, and electrostatic forces in enhancing the sensitivity and selectivity of metal-coo...

Mechanism-Driven Features Enable Asn Deamidation Reactivity Prediction via Machine Learning Methods.

Journal of chemical information and modeling
The spontaneous deamidation of Asparagine (Asn) residues is a common post-translational modification of proteins that can occur on disparate time scales, ranging from hours to thousands of years. This variability in the reaction rate reflects the inf...

ABEEM Polarizable Force Field for PC Lipids: Parameterization and Molecular Dynamics Simulations.

Journal of chemical theory and computation
In additive force fields, the charge is a tunable parameter designed to represent average polarization effects through a mean-field average, which could not accurately respond to different environments. The polarizable force field (PFF) offers enhanc...

Ranking of apparent drug affinity to mesoporous silica utilizing a chromatographic screening method and a tree-based prediction model.

International journal of pharmaceutics
Mesoporous silica has emerged as a promising component in bio-enabling formulation strategy. However, there is currently a lack of predictive tools for assessing drug-silica interactions in a preformulation phase, when formulators only have minimal m...
