Ester Hydrolysis by a Cyclodextrin Dimer Catalyst with a Metallophenanthroline Linking Group
Authors: Zhou Ying‐Hua , Zhao Meng , Mao Zong‐Wan , Ji Liang‐Nian 
Published: July 2008

AbstractA novel β‐cyclodextrin dimer, 1,10‐phenanthroline‐2,9‐dimethyl‐bridged‐bis(6‐monoammonio‐β‐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 (logKML=9.56±0.01) of the complex and deprotonation constant (pKa=8.18±0.04) of the coordinated water molecule were determined by a potentiometric pH titration at (298±0.1) K. Hydrolytic kinetics of carboxylic acid esters were performed with bis(4‐nitrophenyl) carbonate (BNPC) and 4‐nitrophenyl acetate (NA) as substrates. The obtained hydrolysis rate constants showed that ZnL has a very high rate of catalysis for BNPC hydrolysis, giving a 3.89×104‐fold rate enhancement over uncatalyzed hydrolysis at pH 7.01, relative to only a 42‐fold rate enhancement for NA hydrolysis. Moreover, the hydrolysis second‐order rate constants of both BNPC and NA greatly increases with pH. Hydrolytic kinetics of a phosphate diester catalyzed by ZnL was also investigated by using bis(4‐nitrophenyl) phosphate (BNPP) as the substrate. The pH dependence of the BNPP cleavage in aqueous buffer shows a sigmoidal curve with an inflection point around pH 8.11, which was nearly identical to the pKa value from the potentiometric titration. The kcat of BNPP hydrolysis promoted by ZnL was found to be 9.9×10−4 M−1 s−1, which is comparatively higher than most other reported ZnII‐based systems. The possible intermediate for the hydrolysis of BNPP, BNPC, and NA catalyzed by ZnL is proposed on the basis of kinetic and thermodynamic analysis.
Synthesis and Relaxometric Studies of a Dendrimer‐Based pH‐Responsive MRI Contrast Agent

AbstractThe design of effective pH responsive MRI contrast agents is a key goal in the development of new diagnostic methods for conditions such as kidney disease and cancer. A key factor determining the effectiveness of an agent is the difference between the relaxivity of the “on” state compared to that of the “off” state. In this paper, we demonstrate that it is possible to improve the pH‐responsive action of a low molecular weight agent by conjugating it to a macromolecular construct. The synthesis of a bifunctional pH responsive agent is reported. As part of that synthetic pathway we examine the Ing–Manske reaction, identifying an undesirable by‐product and establishing effective conditions for promoting a clean and effective reaction. Reaction of the bifunctional pH responsive agent with a G5‐PAMAM dendrimer yielded a product with an average of 96 chelates per dendrimer. The relaxivity of the dendrimer conjugate rises from 10.8 mM−1 s−1 (pH 9) to 24.0 mM−1 s−1 (pH 6) per Gd3+ ion. This more than doubles the relaxivity pH response, Δr1, of our agent from just 51 % for the original low molecular weight chelate to 122 % for the dendrimer.
