Drug-Loaded, Bivalent-Bottle-Brush Polymers by Graft-through ROMP [PDF]

open access: yes, 2010
Graft through ring-opening metathesis polymerization (ROMP) using ruthenium N heterocyclic carbene catalysts has enabled the synthesis of bottle-brush polymers with unprecedented ease and control Here we report the first bivalent-brush polymers, these ...

Polypropylene-based graft copolymers via CuAAC click chemistry

open access: yeseXPRESS Polymer Letters, 2018
Graft copolymers from commercial chlorinated polypropylene (PP-Cl) possessing either poly(ethylene glycol) (PEG) or poly(ε-caprolactone) (PCL) grafts are synthesized by copper (I)-catalyzed azide-alkyne cycloaddition ‘click’ reaction (CuAAC).

One-Pot Synthesis of Imidazo[1,2-a]pyridines via Groebke–Blackburn–Bienaymé Reaction and CuAAC Assisted by MW

open access: yesChemistry Proceedings
Bis-heterocyclic compounds containing imidazo[1,2-a]pyridines (IMPs) are privileged heterocyclic drug scaffolds due to their potential applications. The Groebke–Blackburn–Bienaymé reaction (GBBR) is a greener alternative to synthesizing IMPs.

Efficient One-Pot Synthesis of Triazole-Linked Morpholinone Scaffolds by CuAAC in the Presence of 18-Crown-6

open access: yesSynOpen, 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 ...

An orthogonally protected CycloTriVeratrylene (CTV) as a highly pre-organized molecular scaffold for subsequent ligation of different cyclic peptides towards protein mimics [PDF]

open access: yes, 2017
The synthesis of a semi-orthogonally protected CycloTriVeratrilene (CTV) scaffold derivative as well as the sequential introduction of three different peptide loops onto this molecular scaffold via Cu(I)-catalyzed azide alkyne cycloaddition towards a ...

NAD tagSeq reveals that NAD+-capped RNAs are mostly produced from a large number of protein-coding genes in Arabidopsis. [PDF]

open access: yes, 2019
The 5' end of a eukaryotic mRNA transcript generally has a 7-methylguanosine (m7G) cap that protects mRNA from degradation and mediates almost all other aspects of gene expression.
