Water‐Compatible SuFEx‐Active Diazonium Linchpin Platform for Rapid Modular Diversification and On‐DNA Functionalization

open access: yesAdvanced Functional Materials, EarlyView.
Sulfur fluoride exchange (SuFEx) is a powerful click platform, yet water‐compatible multifunctional linchpins remain elusive. Here, we report decagram‐scalable diazonium linchpins that enable rapid Pd‐catalyzed diversification and direct, catalyst‐free on‐DNA ligation in aqueous media.

Reversible Tuning of Multiple Molecular Kinking for Stem Cell Regulation In Vivo

open access: yesAdvanced Functional Materials, EarlyView.
In this work, we introduce the novel concept of background component‐free “multiple kinks” material platform composed solely of liganded multiple kink‐bearing molecules as a strategy for dynamic biomaterial design. Tri‐kink molecules enable effective near‐infrared light‐triggered ligand masking and visible light‐triggered ligand exposure, thereby ...

Development of Novel Immobilized Copper–Ligand Complex for Click Chemistry of Biomolecules

open access: yesMolecules
Copper-catalyzed azide–alkyne cycloaddition click (CuAAC) reaction is widely used to synthesize drug candidates and other biomolecule classes. Homogeneous catalysts, which consist of copper coordinated to a ligand framework, have been optimized for high ...

Photo‐Degradable Polyester Networks and Multi‐Photon Printed Objects Based on Cyclic Ketene Acetals

open access: yesAdvanced Functional Materials, EarlyView.
The current work introduces a photoreversible polyester network derived from radical ring‐opening polymerization of cyclic ketene acetals. It combines photoreversible cross‐linking with initiator‐free multi‐photon printing. Reversible network formation, tunable mechanical properties, and selective degradation highlight its potential as a versatile ...

Copper catalysed azide–alkyne cycloaddition (CuAAC) in liquid ammonia

open access: yes, 2012
Copper(I) catalysed azide–alkyne cycloaddition reactions (CuAAC) occur smoothly in liquid ammonia (LNH3) at room temperature to give exclusively 1,4-substituted 1,2,3-triazoles with excellent yields (up to 99%).

Generalizable Strategies for the Synthesis of Cereblon‐Recruiting PROTAC Prodrugs

open access: yesAngewandte Chemie, EarlyView.
Cereblon‐recruiting PROTACs remain challenging to derivatize for prodrug‐based delivery. In this study, three complementary conjugation strategies enabled the efficient synthesis of cleavable PROTAC prodrugs with tunable release kinetics that can be incorporated into a library of PEGylated constructs and bottlebrush prodrugs.

Intermediates Stabilized by Tris(triazolylmethyl)amines in the CuAAC Reaction

open access: yesChemistry – A European Journal, 2017
AbstractTris(triazolylmethyl)amine ligands (TL) are widely used to accelerate the CuI‐catalyzed azide‐alkyne cycloaddition (CuAAC) reaction, but its mechanistic role remains unclear. Using electrospray ionization mass spectrometry, we detected for the first time the trinuclear TL‐CuI3‐acetylide and the dinuclear TL‐CuI2‐acetylide complexes in aqueous ...

Synthesis of a multichromophoric array by sequential CuAAC reactions

open access: yesDyes and Pigments, 2021
Abstract An easily synthesized α-hydroxy-β-azidotetrazole scaffold was used to build a three dimensional polychromic system. Different chromophores (coumarin, BODIPY and distyryl BODIPY) were incorporated into the structure by using sequential CuAAC reactions to form a series of dyads and a triad.

2‐Deoxyglucose Dendrimer‐Enabled Niclosamide Delivery to FRβ‐Expressing Macrophages Alleviates Endometriosis Progression and Associated Hyperalgesia

open access: yesAdvanced Healthcare Materials, EarlyView.
A folic acid (FA)‐conjugated 2‐deoxyglucose dendrimer selectively targets FRβ+ macrophages in endometriotic lesions, enabling precise intracellular delivery of niclosamide. This nonhormonal nanomedicine enhances drug solubility, provides controlled intracellular release, suppresses lesion growth, reduces inflammation and pain, and establishes FRβ ...
