An allosteric receptor by simultaneous "casting" and "molding" in a dynamic combinatorial library



An allosteric receptor by simultaneous "casting" and "molding" in a dynamic combinatorial library



Angewandte Chemie 54(3): 833-837



Allosteric synthetic receptors are difficult to access by design. Herein we report a dynamic combinatorial strategy towards such systems based on the simultaneous use of two different templates. Through a process of simultaneous casting (the assembly of a library member around a template) and molding (the assembly of a library member inside the binding pocket of a template), a Russian-doll-like termolecular complex was obtained with remarkable selectivity. Analysis of the stepwise formation of the complex indicates that binding of the two partners by the central macrocycle exhibits significant positive cooperativity. Such allosteric systems represent hubs that may have considerable potential in systems chemistry.
