AI Article Synopsis

  • Biomolecular binding kinetics, which involve the rates of association (binding) and dissociation (unbinding), are essential for designing effective small-molecule drugs, peptides, and antibodies.
  • Research indicates that the time a drug molecule remains bound (residence time) is a better predictor of its effectiveness than just the strength of the binding (affinity).
  • Various modeling techniques, such as quantitative structure-kinetic relationship models, Molecular Dynamics simulations, and Machine Learning, have been developed to study and predict these binding and dissociation processes; this review highlights recent advances and future directions in the field.

Article Abstract

Biomolecular binding kinetics including the association () and dissociation () rates are critical parameters for therapeutic design of small-molecule drugs, peptides, and antibodies. Notably, the drug molecule residence time or dissociation rate has been shown to correlate with their efficacies better than binding affinities. A wide range of modeling approaches including quantitative structure-kinetic relationship models, Molecular Dynamics simulations, enhanced sampling, and Machine Learning has been developed to explore biomolecular binding and dissociation mechanisms and predict binding kinetic rates. Here, we review recent advances in computational modeling of biomolecular binding kinetics, with an outlook for future improvements.

The controlled binding of proteins on nanoparticle surfaces remains a grand challenge required for many applications ranging from biomedical to energy storage. The difficulty in achieving this ability arises from the different functional groups of the biomolecule that can adsorb on the nanoparticle surface. While most proteins can only adopt a single structure, metamorphic proteins can access at least two different conformations, which presents intriguing opportunities to exploit such structural variations for binding to nanoparticles.

Coverage bias in small molecule machine learning.

Small molecule machine learning aims to predict chemical, biochemical, or biological properties from molecular structures, with applications such as toxicity prediction, ligand binding, and pharmacokinetics. A recent trend is developing end-to-end models that avoid explicit domain knowledge. These models assume no coverage bias in training and evaluation data, meaning the data are representative of the true distribution.

Despite the broad catalytic relevance of metal-support interfaces, controlling their chemical nature, the interfacial contact perimeter (exposed to reactants), and consequently, their contributions to overall catalytic reactivity, remains challenging, as the nanoparticle and support characteristics are interdependent when catalysts are prepared by impregnation. Here, we decoupled both characteristics by using a raspberry-colloid-templating strategy that yields partially embedded PdAu nanoparticles within well-defined SiO or TiO supports, thereby increasing the metal-support interfacial contact compared to nonembedded catalysts that we prepared by attaching the same nanoparticles onto support surfaces. Between nonembedded PdAu/SiO and PdAu/TiO, we identified a support effect resulting in a 1.

Background: Less adequate cardiorespiratory fitness (CRF) is associated with several aspects of Alzheimer's disease (AD) pathology, including neuroinflammation, neurodegeneration and synaptic dysfunction, all of which are known contributors to the clinical outcome - progressive cognitive decline [1]. AD-associated biomolecular changes also seem to be attenuated in carriers of the functionally advantageous variant of the KLOTHO gene (KL-VS) [2]. While KL-VS and CRF both appear to mitigate aspects of AD pathology, they have been exclusively studied in isolation.
