  Toward an Artificial Acetylcholinesterase

  摘要：

  The methanolysis of choline p-nitrophenylcarbonate in chloroform containing 1% methanal is catalyzed with turnover by ditopic receptors 1 and 2, consisting of a calix[6]arene connected to a bicyclic guanidinium by means of a short spacer. The calix[6]arene subunit strongly binds to the trimethylammonium head group through cation-ir interactions, whereas the guanidinium moiety is deputed to stabilize through hydrogen bonding reinforced by electrostatic attraction the anionic tetrahedral intermediate resulting from methoxide addition to the ester carbonyl, The observed cholinesterase activity had been anticipated on the basis of the ability of the ditopic receptors 1 and 2 to bind strongly to the choline phosphate DOPC, which is a transition state analogue far the B(Ac)2-type cleavage of choline esters.

  The aminolysis of choline p-nitrophenyl carbonate is catalyzed with turnover by a deep cavitand bearing an introverted pyridone function. The synergy of action between the recognition of the guest in the binding pocket and the catalytic activity brought to bear by the pyridone is responsible for the high substrate specificity observed.

• Programmed Enzyme-Mimic Hydrolysis of a Choline Carbonate by a Metal-Free 2-Aminobenzimidazole-Based Cavitand

  The hydrolysis of a choline carbonate through a metal-free, enzyme-like mechanism has been achieved using a 2-aminobenzimidazole-based deep cavitand as catalyst. The supramolecular catalysis involves three steps: host guest binding, carbamoylation and enzyme-like hydrolysis. Interestingly the rate-determining step proceeds through a programmed hydrolysis of carbamoylcholine-cavitand intermediate that may be driven by water molecules surrounding the benzimidazole walls of the cavity.

• Catalysis by a Synthetic Receptor Sealed at One End and Functionalized at the Other

  A deep cavitand bearing a zinc (II) salen wall catalyzes the hydrolysis of para-nitrophenylcholine carbonate. The closed end of the cavitand properly positions the carbonyl function of the substrate for activation by the metal center. Substrate specificity for acetylcholine derivatives results from simultaneous cation-pi interactions and a C=O- - -Zn coordination bond.
