The evaluation of anchoring processes and chemical stability of zwitterionic molecules via local reactivity indexes
(2021-06-01)
Exposure of materials to blood can result in numerous interactions such as plasma protein adsorption, blood cell activation, platelet adhesion, and thrombotic reactions. Although strategies to minimize the blood-immune ...
Crystal structure of zwitterionic 4-(ammoniomethyl)benzoate: a simple molecule giving rise to a complex supramolecular structure
(2014)
The asymmetric unit of the title compound, C8H9NO2 H2O consists of an
isolated 4-(ammoniomethyl)benzoate zwitterion derived from 4-aminomethylbenzoic
acid through the migration of the acidic proton, together with a ...
Síntese e caracterização estrutural de polialetos e compostos zwitteriônicos derivados de diteluretos de diarila
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2016-06-22)
The present work describes the synthesis and structural elucidation of ten new tellurium halide starting from diaryl ditellurides (aryl group = 2-piridine or N,N-dimethylbenzilamine). The compounds and starting material ...
Zwitterionic Silane Copolymer for Ultra-Stable and Bright Biomolecular Probes Based on Fluorescent Quantum Dot Nanoclusters
(American Chemical Society, 2017-05)
Fluorescent semiconductor quantum dots (QDs) exhibit several unique properties that make them suitable candidates for biomolecular sensing, including high brightness, photostability, broad excitation, and narrow emission ...
Neutral and zwitterionic dopamine species adsorbed on silver surfaces: A DFT investigation of interaction mechanism
(John Wiley & Sons Inc, 2018-09-27)
Biomolecules nondissociative adsorption on noble metals is a key process in metallic biosensors implying several questions related to the stability and orientation of such molecules. Here, the neurotransmitter dopamine ...
A DFT study of hydration in neutral and zwitterionic norfloxacin
(Elsevier Science, 2006-12)
Hydration of the fluoroquinolone antibiotic norfloxacin has been examined in B3LYP/6-31+G∗ calculations. The neutral and zwitterionic forms and their one- and two-water complexes have been optimized both as isolated molecules ...
Synthesis, X-ray analysis and DFT study of 2-amino-3-(N-oxipiridin-4-ilsulfanil)-propionic acid dihydrate
(OLDENBOURG VERLAG, 2010)
The title compound, C(8)H(14)N(2)O(5)S 2(H(2)O), 2-amino-3-(N-oxipiridin-4-ilsulfanil)-propionic acid dihydrate, is obtained by the reaction of cysteine and 4-nitropyridine N-oxide in dimethylformamide, removing the NO(2) ...
Vesicle-micelle transition in mixtures of dioctadecyldimethylammonium chloride and bromide with nonionic and zwitterionic surfactants
(Amer Chemical Soc, 2006-05-09)
We have investigated the effect of mixing spontaneously formed dispersions of the cationic vesicle-forming dioctadecyldimethylammonium chloride and bromide (DODAX, with X being anions Cl- (C) or Br- (B)) with solutions of ...
