The phosphinoboration of carbodiimides, isocyanates, isothiocyanates and CO₂ [PDF]

, 2017
The transition metal-free addition of phosphinoboronate ester Ph2PBpin (pin = 1,2-O2C2Me4) to heterocumulenes including carbodiimides, isocyanates, isothiocyanates and carbon dioxide proceeds with remarkable selectivity to give products in high yield.

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.

Biomimetic Nanoplatform for Dual Target Nano‐Metabolic Therapy in Diabetes‐Associated Biofilm Infections

Advanced Science, EarlyView.
A biomimetic GOx/Arg‐loaded nanoplatform produces nitric oxide through an in situ catalytic cascade reaction, enabling dual‐target metabolic regulation in diabetes‐associated biofilm infections. Bacterial metabolism is disrupted, and macrophage immunometabolism is reprogrammed, resulting in biofilm eradication, immune restoration, and enhanced ...
