A new series of higher generation cationic N,N-chelating, ruthenium(II)-ethylene-glycol metallodendrimers from first-, second-, third- and fourth-generation pyridylimine-based poly(propylene) dendrimer scaffolds of the type, DAB-(NH2) (where n = 4, 8, 16 o ...
Three PEGylated derivatives of 6-amino-2-[4,7,10-tris(carboxymethyl)-1,4,7,10-tetrazacyclododec-1-yl]hexanoic acid (DOTA-AHA) with different molecular weights were prepared and characterized. Their Gd-III chelates were studied in aqueous solution through v ...
Water exchange kinetics on [Ln(AAZTAPh–NO2)(H2O)q]− (Ln = Gd3+, Dy3+, or Tm3+) were determined by 1H nuclear magnetic resonance (NMR) measurements. The number of inner-sphere water molecules was found to change from two to one when going from Dy3+ to Tm3+. ...
This work aims to evaluate the applicability of EDDS (ethylenediamine-N,N'-disuccinic acid) as an iron chelating agent for photo-Fenton treatment of municipal wastewater spiked with organic contaminants at near-neutral pH. A series of laboratory scale expe ...
A review. Nitroxyl (HNO) is a biol. signaling agent that displays distinctive reactivity compared to nitric oxide (NO). As a consequence, these two reactive nitrogen species trigger different physiol. responses. Selective detection of HNO over NO has been ...
The need for magnetic resonance imaging (MRI) contrast agents with improved relaxivity maintains the development of new Gd-III chelates as an intensive and demanding field of research. In this work, we introduce the new dimeric chelators bis{1,4,7,10-tetra ...
Selective cleavages of carbon-carbon bonds catalyzed by transition-metal complexes have been shown to be increasingly versatile tools for organic synthesis allowing for complementary synthetic strategies. Numerous examples of transition-metal catalyzed C-C ...
To study the influence of hydrazine functions in the ligand skeleton, we designed the heptadentate HYD ligand (2,2',2 '',2 ''-(2,2'-(pyridine-2,6-diyl)bis(2-methylhydrazine-2,1,1-triyl)) tetraacetic acid) and compared the thermodynamic, kinetic, and relaxa ...
The authors recently characterized a series of novel platinum(II) compds. bearing a conserved O,S binding moiety as a bifunctional ligand and evaluated their soln. behavior and antiproliferative properties in vitro against a representative cancer cell line ...
Silver nanoparticles (AgNP) are increasingly used as antimicrobials in consumer products. Subsequently released into aquatic environments, they are likely to come in contact with microbial communities like periphyton, which plays a key role as a primary pr ...
