  Development of a Potent Bcl-x_L Antagonist Based on α-Helix Mimicry

  摘要：

  The rational design of low-molecular weight ligands that disrupt protein-protein interactions is still a challenging goal in medicinal chemistry. Our approach to this problem involves the design of molecular scaffolds that mimic the surface functionality projected along one face of an alpha-helix. Using a terphenyl scaffold, which in a staggered conformation closely reproduces the projection of functionality on the surface of an alpha-helix, we designed mimics of the pro-apoptotic alpha-helical Bak-peptide as inhibitors of the Bak/Bcl-xL interaction. This led to the development of a potent Bcl-xL antagonist (KD = 114 nM), whose binding affinity for Bcl-xL was assessed by a fluorescence polarization assay. To determine the binding site of the developed inhibitor we used docking studies and an HSQC-NMR experiment with 15N-labeled Bcl-xL protein. These studies suggest that the inhibitor is binding in the same hydrophobic cleft as the Bak- and Bad-peptides.

  a library of terphenyl derivatives to mimic the helical region of the Bak BH3 domain that binds Bcl-x(L). Fluorescence polarization assays were carried out to evaluate the ability of terphenyl derivatives to displace the Bcl-x(L)-bound Bak peptide. Terphenyl 14 exhibited good in vitro affinity with a K(i) value of 0.114 muM. These terphenyl derivatives were more selective at disrupting the Bcl-x(L)/Bak
