Electrochemical Investigation of Iron-Catalyzed Atom Transfer Radical Polymerization

Molecules, 2022
Use of iron-based catalysts in atom transfer radical polymerization (ATRP) is very interesting because of the abundance of the metal and its biocompatibility. Although the mechanism of action is not well understood yet, iron halide salts are usually used

Aktivierung von Metallkomplexen durch Ultraschallwellen für eine gezielte Krebstherapie

Angewandte Chemie, EarlyView.
Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.

Synthesis of well-defined polypeptide-based diblock copolymers [PDF]

Polímeros
We report an efficient protocol to synthesize rod-coil diblock copolymers of an α-helical polypeptide and poly(4-vinyl pyridine) via a combination of “living” ring-opening polymerization of α-amino acid N-carboxyanhydrides at 0 °C, polymer end-group ...

Ein Ruthenium(CAAC‐5)‐Olefin‐Metathese‐Katalysator für die Biokonjugation

Angewandte Chemie, EarlyView.
Die Instabilität von Rutheniumkatalysatoren in wässrigen Lösungen schränkt die Olefinmetathese in biologischen Medien ein. Es wird über einen Ru(CAAC‐5)‐Komplex berichtet, der unter biologisch relevanten Bedingungen aktiv bleibt und die Biokonjugation mit Proteinen, Peptiden und einem künstlichen Metalloenzym ermöglicht.

Kinetics of Fe-Mediated ATRP with Triarylphosphines

, 2015
Phosphines have been successfully used as additives for Fe-based ATRP. To understand their role in detail, the kinetics of Fe-based ATRP in the presence of tris­(2,4,6-trimethoxy­phenyl)­phosphine (TTMPP) and of triphenyl­phosphine (TPP) was studied via ...

A Ruthenium(CAAC‐5) Olefin Metathesis Catalyst for Bioconjugation

Angewandte Chemie International Edition, EarlyView.
The aqueous instability of ruthenium catalysts restricts olefin metathesis in biological media. A Ru(CAAC‐5) complex bearing an aniline handle is reported that remains active under biologically relevant conditions and enables bioconjugation to proteins, peptides, and an artificial metalloenzyme, providing a robust platform for olefin metathesis in ...
