C‐Terminal Functionalization Methods of Amino Acids, Peptides, and Proteins

Chemistry – A European Journal, EarlyView.
C‐terminal functionalization offers powerful routes to peptide and protein diversification, yet epimerization, hydrolysis, and selectivity remain key challenges. This Review surveys enzymatic, decarboxylative, and condensation strategies, highlighting advances toward chemo‐ and regioselective, protecting‐group‐free, atom‐efficient methods applicable to

X‐Ray Absorption Sensitivity at 5d$5d$ Edges of High‐Valent Light Actinides to Crystal‐Field Strength and Covalency Effects

Chemistry – A European Journal, EarlyView.
Analysis of x‐ray absorption spectra of U(VI) and U(V) oxides indicates an important role of U 5f−O$5f-\rm{O}$ 2p$2p$ charge transfer for increasing the 5f$5f$ occupancy and thereby affecting the ground state properties. ABSTRACT The 5f$5f$ states were probed in ThO2$\rm{ThO}_2$ and U(VI) and U(V) oxides using x‐ray absorption spectroscopy at the ...

Soluble Nanomedicine Against Soluble Neurosensitizers to Effectively Relieve Osteoarthritis Pain and Joint Damage

Exploration, EarlyView.
Osteoarthritis pain arises not only from joint damage but also from inflammation, abnormal bone changes, and excessive nerve activation inside the joint. In this study, we developed an injectable nanomedicine, LAC, that responds to the acidic environment of osteoarthritic joints to locally release two approved drugs, reducing inflammation, limiting ...
