Silver-catalysed azide–alkyne cycloaddition (AgAAC): assessing the mechanism by density functional theory calculations [PDF]

open access: yesRoyal Society Open Science, 2016
‘Click reactions’ are the copper catalysed dipolar cycloaddition reaction of azides and alkynes to incorporate nitrogens into a cyclic hydrocarbon scaffold forming a triazole ring.

CBT‐Cys click reaction for optical bioimaging in vivo

open access: yesView, 2023
Derived from the D‐luciferin regeneration pathway in firefly body, the click condensation reaction between 2‐cyanobenzothiazole (CBT) and D‐cysteine (Cys) (CBT‐Cys click reaction) possesses unique advantages, including superior biocompatibility, high ...

A method for parallel microscale protein labeling and precise control over the average degree of labeling (aDoL)

open access: yesScientific Reports, 2023
A widely used approach for protein conjugation is through the lysine residues reacting with NHS- or other active esters. However, it is a challenge to precisely control the degree of labeling (DoL) due to the instability of active ester and variability ...

Iterative in Situ Click Chemistry Assembles a Branched Capture Agent and Allosteric Inhibitor for Akt1 [PDF]

open access: yes, 2011
We describe the use of iterative in situ click chemistry to design an Akt-specific branched peptide triligand that is a drop-in replacement for monoclonal antibodies in multiple biochemical assays.

Self-healing metallo-supramolecular hydrogel based on specific Ni2+ coordination interactions of poly(ethylene glycol) with bistriazole pyridine ligands in the main chain [PDF]

open access: yes, 2020
In this study, a supramolecular hydrogel formed by incorporating the 2,6-bis(1,2,3-triazol-4-yl)-pyridine (btp) ligand in the backbone of a polymer prepared by copper(I)-catalyzed alkyne-azide cycloaddition (CuAAC) "click" polyaddition reaction of 2,6 ...

Synthesis of Terpolymers by Click Reactions [PDF]

open access: yesChemistry – An Asian Journal, 2011
AbstractWell‐defined polymeric structures were easily generated through living polymerization systems, in particular, living radical polymerizations. The polymeric precursors with orthogonal functionalities were subsequently clicked together with single or double (combinatorial) click reactions, such as the copper‐catalyzed azide–alkyne cycloadditions (

Acoustic behavior of melon-headed whales varies on a diel cycle. [PDF]

open access: yes, 2015
Many terrestrial and marine species have a diel activity pattern, and their acoustic signaling follows their current behavioral state. Whistles and echolocation clicks on long-term recordings produced by melon-headed whales (Peponocephala electra) at ...

Controlling thermal reactivity with different colors of light [PDF]

open access: yes, 2017
The ability to switch between thermally and photochemically activated reaction channels with an external stimulus constitutes a key frontier within the realm of chemical reaction control.
