Covalent Reprogramming of Kinase Binders to Modulate Protein Abundance

Advanced Science, EarlyView.
Electrophilic remodeling of a broad‐spectrum kinase binder reveals how subtle chemical changes reprogram protein fate. An acrylamide analog of a multi‐kinase binder selectively stabilizes Aurora kinase A (AURKA) by suppressing its ubiquitination, while a short‐linker variant converts this stabilizer into a degrader.

Janus‐Type Electrostatic Potential Gradient‐Activated Dynamic Zn2+‐Coordinating Nitrogen Sites in Molecularly Locked Nanocellulose Separators for Stable Zinc‐Ion Batteries

Advanced Science, EarlyView.
A multifunctional benzimidazole‐terminated CNF separator is constructed via a PEI‐mediated covalent locking strategy, generating dense zincophilic sites that accelerate Zn2+ transport and desolvation while enabling uniform Zn (002) deposition and suppressing side reactions.
