A Stable Isopterin Mimic of a Potent Bacterial Stimulant of T Cells

Chemistry – A European Journal, EarlyView.
A microbial metabolite covalently binds immunological protein MR1 to potently activate specific lymphocytes called MAIT cells, but it is too unstable for biological applications. Here, using synthesis, assays, protein crystallography, and computer modelling, we report a water‐stable analogue that activates reporter cells expressing the MAIT T cell ...

Multi‐Scale Investigation of Supramolecular Organogels Assembled From Pt(II)‐Salphen Complexes

Chemistry – A European Journal, EarlyView.
A family of Pt(II)‐salphen complexes with long alkyl chains is investigated as low‐molecular‐weight organogelators. Multi‐scale characterization of their supramolecular gels reveals how the chain length, Pt‐Pt interactions, and π–π stacking direct self‐assembly and tune gel mechanics.

Partially Biobased Polyurethanes With Reversibly Crosslinkable Furan Units Toward Recyclable Thermosetting Textile Fibres

Chemistry – A European Journal, EarlyView.
A molecular design strategy combines lignin‐derived aromatic units, sugar‐derived furan groups, and flexible glycol segments to create wet‐spinnable polyurethanes. Thermally reversible Diels–Alder crosslinking chemistry enables formation of crosslinked thermosetting fibers, repeated de‐crosslinking/re‐crosslinking cycles, and tunable fiber properties ...

Infrared Irradiation‐Assisted Pd‐Catalyzed C(sp3)─H Arylation and Tandem Cyclization of Ortho‐Tolualdehydes

Chemistry – A European Journal, EarlyView.
A rapid and efficient protocol for the synthesis of 2‐benzylbenzaldehydes and anthracenes is reported, based on the infrared (IR) irradiation‐assisted Pd‐catalyzed C(sp3)─H arylation and the tandem C(sp3)─H arylation/electrophilic aromatic cyclization of ortho‐tolualdehydes with aryl iodides via a transient directing group (TGD) strategy.

Localized Prostate Cancer Therapy: Tumor Microenvironment‐Activated Spermine Hydrogel With Real‐Time Autonomous Fluorescence Sensing

Chemistry – A European Journal, EarlyView.
First tumor microenvironment (TME)‐responsive spermine‐loaded hydrogel with autonomous sensing for advanced local therapy of prostate cancer (PCa) is developed. Spermine can be released from the hydrogel to kill the prostate cancer cells specifically under acidic TME.
