Imprinted nanogels as biomimetic catalysts
The term ‘biomimetic’ is commonly used to describe instances in which a chemical process imitates a biochemical reaction and has attracted considerable interest as more and more scientists study Nature’s phenomena and mechanisms. The design and synthesis of catalytic systems capable of mimicking enzyme’s activity while overcoming some of the protein’s inherent limitations is an important challe...
متن کاملPolymer-supported metal complex oxidation catalysts
Bbstract Recent developments involving polymer-supported metal complexes as catalysts in oxidation reactions, using dioxygen, hydrogen peroxide, alkyl hydroperoxides, hypochlorite anion and iodosobenzene as oxidants are reviewed. binding of dioxygen, and in catalysis, along with the structurally closely related metallo-phthalocyanines, oxidative polymerization catalysed by polymer-supported cop...
متن کاملMetal-coordinating substrate analogs as inhibitors of metalloenzymes.
A group of active-site metal coordinating inhibitors of zinc proteases (carboxypeptidase A, thermolysin, Bacillus cereus neutral protease, and angiotensin-converting enzyme) have been synthesized and their properties investigated. Their general structures are R-SH and R-NH-PO2(O phi)H, where-S- or -O- serve as metal ligands and R refers to an amino acid or peptide group designed to interact wit...
متن کاملWater-soluble sulfonated hyperbranched poly(arylene oxindole) catalysts as functional biomimics of cellulases.
A new polymer acid catalyst, sulfonated hyperbranched poly(arylene oxindole), 5-OH-SHPAO, was prepared for selective cellulose hydrolysis. Its superior catalysis, showing high glucose selectivity at almost full cellulose conversion, is attributed to the presence of an hydroxyl group next to the sulfonic acid, therefore mimicking the separate acid-base pair in the cellulase active site.
متن کاملMolecularly Imprinted Polymer/Metal Organic Framework Based Chemical Sensors
The present review describes recent advances in the concept of molecular imprinting using metal organic frameworks (MOF) for development of chemical sensors. Two main strategies regarding the fabrication, performance and applications of recent sensors based on molecularly imprinted polymers associated with MOF are presented: molecularly imprinted MOF films and molecularly imprinted core-shell n...
