Thermoresponsive self-assembled cyclodextrin-end-decorated PNIPAM for aqueous catalysis.
The catalytic performance of thermoresponsive poly(N-isopropylacrylamide) (PNIPAM) functionalized at the terminal position with randomly methylated β-cyclodextrin was demonstrated by the aqueous Rh-catalysed hydroformylation of higher olefins.
متن کاملDeciphering DNA-based asymmetric catalysis through intramolecular Friedel-Crafts alkylations.
We describe asymmetric intramolecular Friedel-Crafts alkylations with a DNA-based hybrid catalyst and propose a plausible binding model. This study shows promise for studying relationships between the helical chirality of DNA and enantioselectivity of the chemical reaction.
متن کاملInfluence of intramolecular hydrogen bonds on the binding potential of methylated β-cyclodextrin derivatives
Various heptasubstituted derivatives of β-cyclodextrin (β-CD) bearing 1, 2 and 3 methyl substituents per glucose unit were synthesized by regioselective methods. Binding free energies and binding enthalpies of these hosts towards 4-tert-butylbenzoate and adamantane-1-carboxylate were determined by isothermal titration microcalorimetry (ITC). It was found that methyl substituents at the secondar...
متن کاملEffect of temperature on cyclodextrin production and characterization of paracetamol/cyclodextrin complexes.
OBJECTIVE To compare the effect of different reaction temperatures on the cyclization and coupling reactions of the Toruzyme CGTase influencing the yield of cyclodextrins (CDs) and to study the solubility of paracetamol with CDs. MATERIAL AND METHOD Type and amount of CDs were analyzed by HPAEC-PAD. The stability constants for the inclusion complex formed between CDs and paracetamol were dete...
متن کاملEffect of Ultrasound Radiation on the Activity of Cyclodextrin Glucanotransferase
In this study, the effects of ultrasound radiation pretreatment on activity and conformation of cyclodextrin glucanotransferase (CGTase) from Bacillus sp. SK13.002 were investigated. Conformational change on the enzyme structure was studied by fluorescence spectroscopy. Findings showed that the optimum ultrasound radiation pretreatment condition was 25 KHz, 30 W for 20 min in which the activity...
