Molecular biological characterisation of amplified esterases from organophosphate resistant and susceptible 'Culex quinquefasciatus'. [PDF]

open access: yes
Culex mosquitoes, as well as being vectors of filariasis and Japanese encephalitis, are a world wide biting nuisance. Organophosphorus insecticides (OPs) have been widely used to control Culex populations.

Expression, characterization and structural modelling of a feruloyl esterase from the thermophilic fungus Myceliophthora thermophila

open access: yes, 2011
A ferulic acid esterase (FAE) from the thermophilic fungus Myceliophthora thermophila (synonym Sporotrichum thermophile), belonging to the carbohydrate esterase family 1 (CE-1), was functionally expressed in methylotrophic yeast Pichia pastoris.

Xenobiotic-hydrolysing esterases from crops and Arabidopses: characterisation of a S-formylglutathione hydrolase [PDF]

open access: yes, 2003
Esterases represent an ancient family of enzymes, found across all kingdoms, which have diverged and occupied a wide range of functional niches. Because of their biochemical diversity and electrophoretic variability, esterases are widely used as genetic ...

Living Radical Polymerization of Styrene Mediated by Copper(I)/N-n-Alkyl-2-pyridylmethanimine Catalysts

open access: yes, 2016
The polymerization of styrene mediated by copper/N-n-alkyl-2-pyridylmethanimine is reported. Two different types of initiator were employed, viz., 1-phenylethyl bromide, chosen for its similar structure to the final end group of the polymer, and alkyl-2 ...

Direct Electrografting of Poly(2-alkyl-2-oxazoline)s on Gold, ITO, and Gold Nanoparticles for Biopassivation

open access: yes, 2023
Poly(2-alkyl-2-oxazoline)s (POx) bearing an aminophenyl end group were synthesized by cationic ring-opening polymerization; the polymers were then carefully characterized by NMR, size exclusion chromatography, and differential scanning nano calorimetry ...

Lithiation of 2-Alkyl-3-amino- and 2-Alkyl-3-(methylamino)-4(3H)-quinazolinones1

open access: yes, 2016
3-Amino-2-methyl-4(3H)-quinazolinone has been doubly lithiated, on nitrogen and in the 2-methyl group, with n-butyllithium. The lithium reagent thus obtained reacts with a variety of electrophiles (D2O, benzophenone, cyclohexanone, cyclopentanone ...

Conversion of 2-Alkyl-2-(2-oxopropyl)cyclopentane-1,3-diones into 2,3,5- and 2,3,4-Trisubstituted Cyclopent-2-enones by Intramolecular Aldolizations to 2,3-Diacylcyclopropanolates Followed by Remarkable Skeletal Rearrangements1

open access: yes, 2016
2-Alkyl-2-(prop-2-ynyl)cyclopentane-1,3-diones 2, conveniently prepared from 2-alkylcyclopentane-1,3-diones 1 and prop-2-ynyl bromide, afford the triketones 3 by Hg2+-catalyzed hydration of the acetylenic triple bond.

Conductive plastic crystal phases of the 1-alkyl-2-methyl pyrrolinium TFSA salts

open access: yes, 2002
Characterization of a new family of salts, based on a number of 1-alkyl-2-methyl pyrrolinium cations and the bis(trifluoromethane sulfonyl) amide anion (TFSA), is presented. From the thermal analysis, conductivity and X-ray diffraction (XRD) measurements,
