Redox active dendronized polystyrenes equipped with peripheral triarylamines

Dendronized polystyrene having peripheral bromo groups was prepared from the dendronization of unfunctionalized polystyrene with dendritic diarylcarbenium ions bearing peripheral bromo groups using the "cation pool" method. The palladium-catalyzed amination of the peripheral bromo groups with diarylamine gave dendronized polystyrene equipped with peripheral triarylamines, which exhibited two se...

Spectral and redox properties of zinc porphyrin core dendrimers with triarylamines as dendron.

The first and second generation of zinc porphyrin core dendrimers (3 and 4) with triarylamine as dendron have been synthesized via Ullmann coupling reaction. Their absorption and emission spectra indicate that there are strong interactions between zinc porphyrin core and triarylamine dendrons. Zinc porphyrin links with triarylamine causes Soret band broadening and Q band shift as compared with ...

Patients with Active Rheumatoid Arthritis Have Lower Frequency of nTregs in Peripheral Blood

Background: Patients with rheumatoid arthritis (RA) suffer from wide ranges of autoimmune reactions in joints. The mechanism of which is generally unknown and maybe associated with Treg deregulation. Objective: To compare the frequency of nTregs in peripheral blood of patients with active rheumatoid disease with healthy individuals. Methods: Twenty five newly diagnosed patients with active RA d...

Redox active motifs in selenoproteins.

Selenoproteins use the rare amino acid selenocysteine (Sec) to act as the first line of defense against oxidants, which are linked to aging, cancer, and neurodegenerative diseases. Many selenoproteins are oxidoreductases in which the reactive Sec is connected to a neighboring Cys and able to form a ring. These Sec-containing redox motifs govern much of the reactivity of selenoproteins. To study...

Bridged triarylamines: a new class of heterohelicenes.

A series of bridged triarylamines, which constitute a new class of heterohelicenes, have been synthesized using a simple three-step procedure. These compounds are shown to be highly luminescent chromophores and are capable of being oxidized. The solid-state structures of these helicenes show a tendency for pi-stacking interactions into an overall zigzag motif.
