SynOpen, 2018 A range of bis-heterocyclic derivatives based on novel morpholinone and triazole heterocycles was prepared from iodo-morpholinone. The key step in our strategy is a one-pot procedure based upon copper-catalysed alkyne-azide cycloaddition (CuAAC) from ...

European Journal of Organic Chemistry, EarlyView.Intramolecular cyclization to quench an in situ reduction‐generated azaquinone methide is a strategy that could be used for late‐stage heterocycle synthesis. Herein, synthetically accessible 4‐nitrobenzyl alcohols with a nucleophilic handle adjacent to the benzyl alcohol group are reduced under mild conditions to afford six‐ and seven‐membered ...

Combined Ugi‐4CR/CuAAC Approach to Triazole‐Based Neoglycolipids
European Journal of Organic Chemistry, 2014 AbstractNew glycolipids that feature a carbohydrate/triazole/lipid hybrid architecture were readily produced by a combined multicomponent/click approach. The process comprises the use of the Ugi four‐component reaction to construct double‐lipidic scaffolds that have either alkyne or azide functionalities followed by conjugation to mono‐ and ...

A personal 360° view of applications of ‘biomimetic’ molecular recognition
Journal of Chemical Technology &Biotechnology, EarlyView.Abstract Molecular recognition between biological molecules has formed the basis for innumerable applications in biotechnology for the last seven decades or so. Techniques such as affinity chromatography, solid‐phase and aqueous two‐phase extraction, affinity precipitation, biomimetic catalytic systems, biosensors and molecular imprinting all exploit ...

Fluorogenic “click” reaction for labeling and detection of DNA in proliferating cells
BioTechniques, 2010 A thymidine analog, 5-ethynyl-2′-deoxyuridine (EdU), has been reported as a rapid labeling tool for direct measurement of cells in S-phase. The alkynyl group of EdU is a biologically inert group that undergoes an extremely selective reaction with azido ...

Macromolecular Rapid Communications, EarlyView.Little is known about the cellular uptake of single chain nanoparticles that are cross‐linked with dynamic bonds. Using Förster resonance energy transfer and fluorescence lifetime imaging microscopy (FRET‐FLIM) the dynamic nature of the bonds is seen, in which the interaction between two peptides, disassemble quickly, relatively.

Click Chemistry (CuAAC) and Detection of Tagged de novo Synthesized Proteins in Drosophila
Bio-Protocol, 2019 Copper-catalyzed azide-alkyne-cycloaddition (CuAAC), also known as ‘click chemistry’ serves as a technique for bio-orthogonal, that is, bio-compatible labeling of macromolecules including proteins or lipids.

Macromolecular Rapid Communications, EarlyView.Diacetylene‐containing glycan mimetics cluster upon selective lectin binding in GUVs. Subsequent irradiation leads to the formation of fluorescent polymer clusters, while non‐clustered glycan mimetics remain unaffected in the membrane. ABSTRACT The glycocalyx, a dense layer of glycoproteins and glycolipids on eukaryotic cells, is essential for cellular

A Non‐Antigenic Randomized Polyethylene Glycol/Poly(2‐Phenyl‐2‐Oxazine)‐Based Drug Delivery Platform
Macromolecular Rapid Communications, EarlyView.Randomized PEG (rPEG), a conceptually new PEG alternative, is combined with poly(2‐phenyl‐2‐oxazine) (PPheOzi) to establish an rPEG‐b‐PPheOzi‐b‐rPEG micellar drug delivery platform. The PPheOzi block enables high drug loadings, while competitive ELISA reveals a drastic reduction in anti‐PEG antibody affinity of rPEG in comparison to PEG.

Clicked H-Shaped Arylopeptoids
MoleculesThis study presents a tentative synthesis of supported H-shaped and ladder-type compounds. If the ladders were not accessible, probably due to distance misfits between the reactive centers, a facile method for the synthesis of H-shaped N-alkylated ...
