Thermodynamic profiling of conformationally constrained cyclic ligands for the PDZ domain.

Published

Journal Article

Inspired by structure-based design and tailored for combinatorial preparation, a series of novel cyclic peptides has been developed to yield binding ligands for the third PDZ domain (PDZ3) of PSD-95. These side chain-side chain bridged peptides permit the systematic expansion or contraction of ring size, which is intended to maximize the conformational diversity of the ensemble. Isothermal titration calorimetry (ITC) was used to measure the dissociation constants (K(d)) and associated thermodynamic binding parameters.
