A Chemically Defined Four‐Component Self‐Adjuvanting Tn Vaccine Activating Mincle, FcγR, and CD206 for Enhanced Antitumor Immunity

Advanced Science, EarlyView.
A fully synthetic four‐component vaccine has been developed combining Tn antigen, vizantin (Mincle agonist), rhamnose (antibody recruitment), and mannose (CD206 targeting). By synergistically activating Mincle, FcγR, and CD206 pathways, it elicits strong IgG switching and cytotoxic T‐cells, significantly inhibiting tumors in mice.

Chemoselective Metabolomics via a Modular Reactivity‐Encoding Platform

Advanced Science, EarlyView.
Conventional LC–MS underrepresents numerous metabolites due to heterogeneous ionization efficiencies and matrix interference. Here, we introduce a modular reactivity‐encoding platform (MREP) comprising four alkyne‐tagged probes that selectively derivatize key functional groups, followed by unified click‐chemistry capture to eliminate matrix components ...

Mild C─F Activation of Azido(per)Fluoroalkanes

Chemistry – A European Journal, EarlyView.
Mild and selective activation of C(sp3)–F bonds in azido(per)fluoroalkanes using thiolates was developed, leading to novel functionalized azides. The reaction is initiated by nucleophilic attack of the sulfur atom to the terminal nitrogen of the azido group, followed by fluoride ion elimination.
