Synthesis and structure of 1,4-dipiperazino benzenes: chiral terphenyl-type peptide helix mimetics.
نویسندگان
چکیده
The terphenyl structure has been proven to be an ideal scaffold mimicking side-chain functionalities of peptidic alpha-helices. The synthesis of 1,4-dipiperazino benzenes, using stepwise transition metal-catalyzed N-arylation of chiral piperazines to a central benzene core is reported. The structure determination by X-ray crystallography reveals a geometrical arrangement of the hydrophobic side chains resembling the orientation of key i, i + 3, and i + 7 positions in a peptidic alpha-helix or in terphenyl helix mimetics.

p53 A-Helix mimetics antagonize p53/MDM2 interaction and activate p53
Overexpression or hyperactivation of MDM2 contributes to functional inactivation of wild-type p53 in nearly 50% of tumors. Inhibition of p53 by MDM2 depends on binding between an NH2-terminal (residues 16–28) p53 A-helical peptide and a hydrophobic pocket on MDM2, presenting an attractive target for development of inhibitors against tumors expressing wild-type p53. Here we report that novel p53...

متن کاملProtein recognition motifs: design of peptidomimetics of helix surfaces.
Helices represent one of the most common recognition motifs in proteins. The design of nonpeptidic scaffolds, such as the 3,2',2''-tris-substituted terphenyl, that can imitate the side-chain orientation along one face of an alpha-helix potentially provides an effective means to modulate helix-recognition functions. Here, based on theoretical arguments, we described novel alpha-helix mimetics wh...

A series of substituted diaryltriazoles was prepared by a solid-phase-synthesis protocol using a modified Wang resin. The copper(I)- or ruthenium(II)-catalyzed 1,3-cycloaddition on the polymer bead allowed a rapid synthesis of the target compounds in a parallel fashion with in many cases good to excellent yields. Substituted diaryltriazoles resemble a molecular structure similar to established ...
