A pilot study comparing the metabolic profiles of elite-level athletes from different sporting disciplines [PDF]

open access: yes, 2018
Background: The outstanding performance of an elite athlete might be associated with changes in their blood metabolic profile. The aims of this study were to compare the blood metabolic profiles between moderate- and high-power and endurance elite ...

Targeting the GPX4–FUNDC1 Interaction with Magnesium Lithospermate B Attenuates Sepsis‐Associated Lung Injury

open access: yesAdvanced Science, EarlyView.
The diagram depicts the endothelial‐protective mechanism of magnesium lithospermate B (MLB) in sepsis‐associated lung injury. MLB binds GPX4 at Gly79, disrupts its interaction with FUNDC1, prevents mitophagy‐mediated GPX4 degradation, restores mitophagic flux, reduces ROS, and limits ferroptosis.

Unnatural Tripeptides as Potent Positive Allosteric Modulators of T1R2/T1R3 [PDF]

open access: yesACS Medicinal Chemistry Letters, 2019
T1R2/T1R3 belongs to G protein coupled receptors, which recognizes diverse natural and synthetic sweeteners. A novel class of positive allosteric modulators (PAMs) of T1R2/T1R3 was identified through high-throughput screening campaign. Comparing the structure of the potent compound with previously known PAM, we classified the structure of known PAM ...

GPCRs in CAR‐T Cell Immunotherapy: Expanding the Target Landscape and Enhancing Therapeutic Efficacy

open access: yesAdvanced Science, EarlyView.
Chimeric antigen receptor T cell therapy faces dual challenges of target scarcity and an immunosuppressive microenvironment in solid tumors. This review highlights how G protein‐coupled receptors can serve as both novel targets to expand the therapeutic scope and functional modules to enhance CAR‐T cell efficacy.

Evolution of sparsity and modularity in a model of protein allostery

open access: yes, 2014
The sequence of a protein is not only constrained by its physical and biochemical properties under current selection, but also by features of its past evolutionary history.

Cryo‐EM Structures Reveal the Molecular Basis of Asymmetric Allosteric Activation by MMOB in the Hydroxylase of Soluble Methane Monooxygenase

open access: yesAdvanced Science, EarlyView.
Cryo‐EM analysis reveals an asymmetric MMOH–MMOB complex with distinct protomers, where MMOB binding triggers structural rearrangements from the surface to the active site. This conformational asymmetry shortens the Fe···Fe distance to 2.7 Å in one protomer, forming a geometry suitable for O2 activation and supporting a sequential catalytic mechanism ...

The 10–23 DNAzyme in Biosensing and Diagnostics: Applications, Challenges, and Future Directions

open access: yesAngewandte Chemie, EarlyView.
This review focuses on the 10–23 DNAzyme in diagnostics, spanning unregulated and regulated target‐recognition modes, and their functionalization across colorimetric, fluorescent, electrochemical, electrochemiluminescent, and intracellular biosensing strategies.

Positive Allosteric Modulators for mGluR2 Receptors: A Medicinal Chemistry Perspective [PDF]

open access: yesCurrent Topics in Medicinal Chemistry, 2014
This review summarizes drug discovery efforts on mGluR2 positive allosteric modulators (PAMs) from 2000 to 2013. Medicinal chemistry programs and the identified 21 chemotypes are analyzed and compared in terms of their biological activity and ligand efficiency. Comparative analysis of ligand efficiency metrics including ligand efficiency and lipophilic

Synthetic Analogues of the Snail Toxin 6-Bromo-2-mercaptotryptamine Dimer (BrMT) Reveal That Lipid Bilayer Perturbation Does Not Underlie Its Modulation of Voltage-Gated Potassium Channels [PDF]

open access: yes, 2018
Drugs do not act solely by canonical ligand–receptor binding interactions. Amphiphilic drugs partition into membranes, thereby perturbing bulk lipid bilayer properties and possibly altering the function of membrane proteins.
