Efficient promotion of phosphate diester cleavage by a face-to-face cyclodextrin dimer without metal.

چکیده
An organic face-to-face cyclodextrin dimer promotes the cleavage of bis(4-nitrophenyl) phosphate efficiently in neutral pH without the addition of metal. Both of the phosphate diester bonds can be cleaved.

Ester hydrolysis by a cyclodextrin dimer catalyst with a metallophenanthroline linking group.
A novel beta-cyclodextrin dimer, 1,10-phenanthroline-2,9-dimethyl-bridged-bis(6-monoammonio-beta-cyclodextrin) (phenBisCD, L), was synthesized. Its zinc complex (ZnL) has been prepared, characterized, and applied as a new catalyst for diester hydrolysis. The formation constant (logK(ML)=9.56+/-0.01) of the complex and deprotonation constant (pK(a)=8.18+/-0.04) of the coordinated water molecule ...
متن کاملRapid hydrolysis of phosphate ester promoted by Ce(IV) conjugating with a β-cyclodextrin monomer and dimer.
Two N-donor ligands (L(1) and L(2)) derived from a β-cyclodextrin (βCD) monomer and dimer were employed to mediate the hydrolytic activity and stability of the Ce(IV) ion in aqueous solution. Complexes Ce(IV)-L(1) and Ce(IV)-L(2) were prepared in situ and characterized by means of UV-vis and NMR measurements. Ce(IV)-L(1) catalyzed the hydrolysis of a DNA model, bis(4-nitrophenyl)phosphate (BNPP...
متن کاملEfficient Second Strand Cleavage during Holliday Junction Resolution by RuvC Requires Both Increased Junction Flexibility and an Exposed 5′ Phosphate
BACKGROUND Holliday junction (HJ) resolution is a critical step during homologous recombination. In Escherichia coli this job is performed by a member of the RNase H/Integrase superfamily called RuvC, whereas in Schizosaccharomyces pombe it has been attributed to the XPF family member Mus81-Eme1. HJ resolution is achieved through the sequential cleavage of two strands of like polarity at or clo...
متن کاملSome Conditions for Characterizing Minimum Face in Non-Radial DEA Models with Undesirable Outputs
The problem of utilizing undesirable (bad) outputs in DEA models often need replacing the assumption of free disposability of outputs by weak disposability of outputs. The Kuosmanen technology is the only correct representation of the fully convex technology exhibiting weak disposability of bad and good outputs. Also, there are some specific features of non-radial data envelopment analysis (DEA...
متن کاملCyclodextrin retinylidene: a biomimetic kinetic trap model for rhodopsin.
All trans retinal was attached to both the primary face and the secondary face of beta-cyclodextrin via a Schiff base linkage, analogous to that in rhodopsin. The new models were evaluated and compared with n-butylamine retinylidene Schiff base for their rates of hydrolysis, and factors that influence such rates. Competition studies using adamantane carboxylate demonstrated the kinetic trap the...
