Conformational Heterogeneity, Self-Assembly, and Gas Adsorption Studies of Isomeric Hybrid Peptides
摘要:
The folding and self-assembly propensities of three synthetic isomeric aliphatic aromatic backbone hybrid peptides are illustrated. Single crystal X-ray diffraction studies of three isomeric hybrid dipeptides Boc-Phe-x-aminobenzoic acid (x = o/m/p) reveal that the peptides adopt unconventional conformations which self-assemble to form diverse supramolecular architectures using hydrogen bonding interactions and other noncovalent interactions in the solid state. The N-2 sorption propensities of the isomeric hybrid peptides in the solid state significantly vary with folding and self-assembly nature. The peptides 1 and 2 exhibit type-III N-2 sorption isotherm, though peptide 1 adsorbs 2-fold higher N-2 than does peptide 2.

(EN) The present invention provides novel renin-inhibiting peptides of the formula X-A6-B7-C8-D9-E10-F11-G12-H13-I14-Z, containing aryl acid derived moieties of the formula XL2b which are substituted for Phe8-His9, X and Z are terminal groups, and the remaining variables are absent or are amino acid residues. Such inhibitors are useful for the diagnosis and control of renin-dependent hypertension and other related diseases.(FR) Nouveaux peptides inhibiteurs de la rénine de formule X-A6-B7-C8-D9-E10-F11-G12-H13-I14-Z, contenant des parties dérivées de l'acide d'aryle de formule XL2b, qui sont substituées au Phe8-His9, X et Z sont des groupes en fin de chaîne, et les variables restantes sont absentes ou bien sont des résidus aminoacides. Ces inhibiteurs sont utiles pour le diagnostic et la maîtrise de l'hypertension liée à la rénine et d'autres maladies apparentées.
