Rational Design of Broad‐Spectrum Anti‐Enteroviral Molecular Glues Targeting Enteroviral RNAi Suppressors

Advanced Science, EarlyView.
By leveraging this homodimerization mechanism, molecular glues were rationally designed to induce dysfunctional 3A dimerization, thereby restoring antiviral RNAi. The optimal molecular glue, VTP‐32, demonstrated potent and pan‐enterovirus (groups A, B, D) antiviral effects.

Cucurbit[8]Uril Achieved Single‐Molecule Chiral Transfer to Supramolecular Circularly Polarized Luminescence

Advanced Science, EarlyView.
A single‐molecule cascade supramolecular system comprising L/D‐FPy, CB[8], and SC4AD serves as an efficient light‐harvesting platform. It facilitates cascade energy transfer and chiral transfer to acceptor dyes. Co‐assembly with a PVA matrix produces a multicolor solid film that exhibits enhanced luminescence dissymmetry factors (glum), enabling ...

Unpredictable Dynamic Behaviour of Ruthenium Chelate Pyrrole Derivatives

Molecules
Reaction of [Ru(H)2(CO)(PPh3)3] 1 with an equimolar amount of pyrrole-2-carboxylic acid (H2L1) leads to the homoleptic chelate derivative k2(O,O)-[RuH(CO)(HL1)(PPh3)2] 2.

Heterogeneous Visible‐Light Photocatalysis in Continuous‐Flow: A Synergistic Strategy for Challenging Trifluoromethylation of α, α‐Diaryl Allylic Alcohols via 1,2‐aryl Migration

Advanced Science, EarlyView.
A continuous‐flow photocatalytic strategy is presented for the efficient synthesis of β‐trifluoromethyl ketones under visible light. Using a recyclable solid photocatalyst and an inexpensive CF3 source, the method enables rapid reactions, easy scale‐up, and smooth integration into multistep flow synthesis of bioactive molecules.
