Synthesis, analysis, cholinesterase-inhibiting activity and molecular modelling studies of 3-(dialkylamino)-2-hydroxypropyl 4-[(alkoxy-carbonyl)amino]benzoates and their quaternary ammonium salts
(Molecular Diversity Preservation International, 2017-12)
Tertiary amines 3-(dialkylamino)-2-hydroxypropyl 4-[(alkoxycarbonyl)amino]benzoates and their quaternary ammonium salts were synthesized. The final step of synthesis of quaternary ammonium salts was carried out by ...
Synthesis and properties of cleavable quaternary ammonium compounds
(Japan Oil Chemists’ Society, 2021-03)
Quaternary ammonium compounds are widely used as antiseptic and disinfectant. It is been a concern that their widespread use will lead to an increase of environmental problems, therefore the development of biodegradable ...
Quaternary Ammonium “Tannate” for Antifouling Coatings
(American Chemical Society, 2012-12)
The undesirable accumulation of a wide variety of marine organisms (biofouling) on ship hulls can lead to significantly increased costs, principally by increased fuel consumption to maintain cruising speed. Generally, these ...
Synthesis and Properties of New Cleavable Cationic Surfactants Containing Carbonate Groups
(Springer Heidelberg, 2021-05)
A novel series of cleavable alkyltrimethylammonium surfactants with different hydrocarbon chain lengths (C8–16) were synthesized. A carbonate break site inserted between the polar head and the hydrocarbon chain makes these ...
Pseudomonas putida Δ9-fatty acid desaturase: Gene cloning, expression, and function in the cationic surfactants stress
(Wiley VCH Verlag, 2019-05)
Pseudomonas putida counteract the fluidizing effect of cationic surfactants decreasing the content of membrane unsaturated fatty acid (UFA). A Δ9-fatty acid desaturase gene (desA) from P. putida was isolated, cloned, and ...
Dual antibacterial effect of immobilized quaternary ammonium and aliphatic groups on PVC
(Royal Society of Chemistry, 2015-09)
A coating comprising quaternary ammonium salts (QAS) and aliphatic moieties was formed on the poly(vinyl chloride) (PVC) surface in order to confer antibacterial activity. This was achieved by grafting mercaptopropyltrim ...
Characterization of quaternary ammonium compounds in Flourensia xerophytic communities and response to UV-B radiation
(Elsevier Science, 2014-05)
As part of ongoing studies aimed at characterizing molecular components involved in the ecophysiological adaptations of native xerophytic plants from central Argentina, we demonstrated the presence of compatible solutes ...
Structure-activity relationships for Poly(phenylene)vinylene derivatives as antibacterial agents
(Wiley, 2018-07-03)
A series of poly(phenylene)vinylene (PPV) derivatives with different geometries and peripheral functional groups have been synthesized by Horner-Wadsworth-Emmons reaction. Compounds bearing carboxylic acid or quaternary ...
Synthesis and surface-active properties of novel cleavable gemini surfactants
(Springer Heidelberg, 2021-09)
A novel series of quaternary ammonium gemini compounds having a butynylene spacer and different hydrocarbon chain lengths (CGBu8-16) were prepared. Carbonate group inserted between the hydrocarbon chains and the polar heads ...
Reversible modulation of the redox activity in conducting polymer nanofilms induced by hydrophobic collapse of a surface-grafted polyelectrolyte
(Academic Press Inc Elsevier Science, 2018-05)
We present the covalent modification of a Pani-like conducting polymer (polyaminobenzylamine, PABA) by grafting of a polyelectrolyte brush (poly [2-(methacryloyloxy)-ethyl-trimethylammonium chloride], PMETAC). As PABA has ...
