Lipid Pocket Binders Impose Allosteric Changes of Protein Dynamics Around the Active Site of the Protein Kinase p38α

open access: yesAngewandte Chemie International Edition, EarlyView.
Used in search of novel allosteric sites in the serine/threonine kinase p38α, NMR spectroscopy reveals a dynamic coupling between the catalytic and lipid pockets. The findings uncover a motional interdependence that links distant regions of the enzyme, highlighting the lipid pocket as a promising site for allosteric intervention.

Synthetic Cathepsin B Sensitive Adjuvant‐Peptide Conjugates to Target Intracellular Toll‐Like Receptors 7 and 8

open access: yesChemistryEurope, EarlyView.
Cathepsin B‐sensitive peptide–adjuvant conjugates are designed, synthesized, and evaluated to deliver an antigenic peptid and an adjuvant targeting Toll‐like receptors 7 and 8 (TLR7/8) to antigen presenting cells. The adjuvant is released by cathepsin B resulting in antigen presentation and TLR mediated T cell activation.

Efficacy and safety of fruquintinib combined with albumin‐bound paclitaxel as second‐line therapy for advanced gastric cancer following failure of PD‐1 inhibitor‐containing treatment (TACTIC GC‐01): A phase II single‐arm study

open access: yesInternational Journal of Cancer, EarlyView.
What's New? Anti‐angiogenic drugs have shown promising efficacy as a second‐line treatment for advanced gastric cancer. However, it remains unclear how alterations in the tumor microenvironment following first‐line immunotherapy may impact tumor angiogenesis and influence subsequent therapeutic outcomes. This single‐arm study prospectively explored the

Covalent drug discovery: Progress against key targets, emerging strategies and lessons learnt

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Covalent drug discovery is currently experiencing a boom in industrial and academic interest. To date, at least 75 covalent drugs have received regulatory approval, targeting both traditional target classes and more challenging proteins for which other approaches failed. In many cases, unique aspects of covalent targeting are essential for the
