    Conformational rigidity versus flexibility in a novel peptidic neurokinin A receptor antagonist (1995)

    Notes: Neurokinin A receptor antagonists have been proposed as a new class of drugs for several applications in humans (asthama, intestinal motility, etc.). The rational design, synthesis, structural characterization and biological activity evaluation of a new potent, highly selective, long-lasting, peptide-based receptor antagonist are reported. The structure-activity relationship indicates that the conformational rigidity determines potency, specificity and especially the long life of the molecule in the living body. MEN 10627 is the prototype of a new class of cyclic, peptide-based, neurokinin A receptor antagonists and it is a suitable candidate for clinical testing in humans.

    Bicyclic peptides as type I/type II β-turn scaffolds (1996)

    Notes: We recently reported the rational design, synthesis, and structural characterization of the most potent and selective peptide-based neurokinin A antagonist thus far described: cyclo(Met1-Asp2-Trp3-Phe4-Dap5-Leu6)cyclo(2β-5β). Its bicyclic structure is characterized by a type I and a type II two β-turn around Trp3-Phe4 and Leu6-Met1, respectively. In order to understand whether the two different β-turned structures are determined by the bicyclic structure or by the amino acid type at the corner positions, we have synthesized the pseudosymmetrical analogue cyclo(Phe1-Asp2-Trp3-Phe4-Dap5-Trp6)cyclo(2β-5β). The structural characterization in the crystal state and in solution, here reported, gives an experimental evidence that the backbone of the bicyclic structure is a rigid scaffold that can be used to build both a type I and type II β-turn independently from the amino acid composition. © 1997 John Wiley & Sons, Inc.
