  Discovery of Subnanomolar Arginine-Glycine-Aspartate-Based α_Vβ₃/α_Vβ₅ Integrin Binders Embedding 4-Aminoproline Residues

  摘要：

  The embodiment of 4-aminoproline residues (Amp) into the arginine-glycine-aspartate (RGD) sequence led to the discovery of a novel class of high-affinity alpha v beta(3)/alpha v beta(5) integrin binders [IC50h(alpha v beta(3)) 0.03-5.12 nM; IC50h(alpha v beta(5)) 0.88-154 nM]. A total of eight cyclopeptides of type cyclo-[-Arg-Gly-Asp-Amp-], 5-12, were assembled by a standard solid-phase peptide synthesis protocol that involved the C2-carboxyl and C4-amino functionalities of the proline scaffolds, leaving the N-alpha-nuclear site untouched. Functionalization of this vacant proline site with either alkyl or acyl substituents proved feasible, with significant benefit to the integrin binding capabilities of the ligands. Notably, six out of eight cyclopeptide inhibitors, 5-7 and 9-11, showed moderate yet significant selectivity toward the alpha v beta(3) receptor. The three-dimensional structure in water was determined by NMR techniques and molecular dynamics calculations. Docking studies to the X-ray crystal structure of the extracellular segment of integrin alpha v beta(3) complexed with reference compound 1 were also performed on selected analogues to highlight the structural features required for potent ligand binding affinity.
