Abstract
The current study presents for the first time the synthesis of a new 2:1-[α/aza]-pseudopeptide series possessing charged amino acids (i.e., lysine) and aims at studying the influences of chirality, backbone length, and the nature of the lysine side chains on the conformation of the 2:1-[α/aza]-oligomers in solution using NMR, FTIR spectroscopy and molecular dynamic calculations. The spectroscopic results emphasized the conservation of the β-turn conformation adopted by the trimers regardless of the chirality which demonstrated a noticeable effect on the conformation of homochiral hexamer (8c) compared with the hetero-analogue (8d). The molecular dynamic calculations predicted that the chirality and the side chain of the lysine residues caused a little distortion from the classical β-turn conformation in the case of short trimer sequences (7c and 7d), while the chirality and the backbone length exerted more distortion on the β-turn adopted by the longer hexamer sequences (8c and 8d). The large disturbance in hexamers from classical β-turn was attributed to increasing the flexibility and the possibility of molecules to adopt a more energetically favorable conformation stabilized by non-classical β-turn intramolecular hydrogen bonds. Thus, alternating d- and l-lysine amino acids in the 2:1-[α/aza]-hexamer (8d) decreases the high steric hindrance between the lysine side chains, as in the homo analogue (8c), and the distortion is less recognized. Finally, short sequences of aza-pseudopeptides containing lysine residues improve CO2 separation when used as additives in Pebax® 1074 membranes. The best membrane performances were obtained with a pseudopeptidic dimer as an additive (6b′; deprotected lysine side chain), with an increase in both ideal selectivity αCO2/N2 (from 42.8 to 47.6) and CO2 permeability (from 132 to 148 Barrer) compared to the virgin Pebax® 1074 membrane. A new 2:1-[α/aza]-pseudopeptide series based charged lysine amino acid was synthesized. Influences of chirality, backbone length, and lysine side chains on the oligomers conformation were investigated in solution using NMR, FTIR and MD calculations.![]()

Abstract
α-Aminoxy and α-hydrazino acids are β-amino acid analogs with β-carbons replaced by oxygen and nitrogen, respectively. Such heteroatoms dictate the folding of peptides into specific secondary structures called pseudo-γ-turns. Achiral α-aminoxyacetic acid (NOGly) and l-α-hydrazinophenylalanine (l-NNPhe) have been shown to be suitable for single incorporation during ribosomal translation, but whether ribosomes tolerate other types of α-aminoxy/α-hydrazino acids with l/d-configurations is unknown. Moreover, whether multiple or consecutive incorporations are possible remains unclear. We show, for the first time, multiple and consecutive incorporations of α-aminoxy/α-hydrazino acids with l/d-configurations into various model peptides, including macrocyclic peptide scaffolds.

Abstract
Examination of local folding and H-bonding patterns in model compounds can be extremely informative to gain insight into the propensity of longer-chain oligomers to adopt specific folding patterns (i.e. foldamers) based on remote interactions. Using a combination of experimental techniques (i.e. X-ray diffraction, FT-IR absorption and NMR spectroscopy) and theoretical calculations at the density functional theory (DFT) level, we have examined the local folding patterns induced by the urea fragment in short-chain aza analogues of beta- and gamma-amino acid derivatives. We found that the urea-turn, a robust C(8) conformation based on 1<--3 H-bond interaction, is largely populated in model ureidopeptides (I-IV) obtained by replacing the alpha-carbon of a beta-amino acid by a nitrogen. This H-bonding scheme is likely to compete with remote H-bond interactions, thus preventing the formation of secondary structures based on remote intrastrand interactions in longer oligomers. In related oligomers obtained by the addition of a methylene in the main chain (V-VIII), nearest-neighbour H-bonded interactions are unfavourable i.e. the corresponding C9 folding pattern is hardly populated. In this series, folding based on remote intrastrand interactions becomes possible for longer oligomers. We present spectroscopic evidence that tetraurea VIII is likely to be the smallest unit capable of reproducing the H-bonded motif found in 2.5-helical N,N'-linked oligoureas.

Abstract
[structures: see text] We studied the conformation of a series of primary amides in a solution of chloroform. Classical NMR tools such as dilution experiments, influence of DMSO, and 2D-NOESY, together with X-ray diffraction, were combined with an analysis of the difference of the chemical shift Deltadelta between the geminal amidic protons. This study was addressed in order to understand the conformation adopted by hydrazino acetamides 1a and 1b as model compounds for aza-beta3-peptides. In this manner, it was possible to show that the amidic group of these compounds acts as a H-bond donor and interacts with two different H-bond acceptors. We concluded that the hydrazinoturn, a specific bifurcated H-bond system observed in the solid state, is also the preferred conformation of hydrazino acetamides 1a and 1b in solution. Our results show that the short-range interaction with the N(alpha)-nitrogen lone pair not only stabilizes the C8 pseudocycle but could also contribute to the folding process of aza-beta3-peptides. In light of this, it could explain why aza-beta3-peptides develop a different H-bond network in comparison to their isosteric beta3-peptides analogues. Our work is in keeping with the recent interest of hydrazino peptides as an extension of the beta-peptide concept.

Abstract
[structure: see text] Various sequences of modified peptides including those containing a cis- or trans-vinylogous residue have been studied using X-ray diffraction in the solid state and 1H NMR and IR spectroscopy in solution. A cis-vinylogous residue promotes an NH to CO intramolecular H-bond, closing a nine-membered pseudocycle that stabilizes a folded moiety that we proposed to name the cis-vinylogous turn. A trans-vinylogous residue involves an extended conformation. Two consecutive vinylogous residues retain their own structural propensity: "Xaa(tr)"-"Xaa(cis)" or "Xaa(cis)"-"Xaa(tr)" sequence is singly folded, whereas "Xaa(cis)"-"Xaa(cis)" sequence is doubly folded. Oligo vinylogs with all-trans or all-cis or alternating cis-trans motifs could constitute new classes of foldamers.

Abstract
Crystals of aza-beta3-peptides have been obtained. This gives the first opportunity for hydrazino peptides, in the sense of oligomers built exclusively with alpha-hydrazinoacetic units, to be observed in the solid state. The structures make it clear that the H-bond network developed by aza-beta3-peptides differs radically from those of the corresponding beta3-peptides but strongly resembles that of the alpha-aminoxy peptides. Our study contributes to the current interest in hydrazino peptides as an extension of the beta-peptide concept.

A general two-step preparation of enantiopure N(alpha),N(beta)-orthogonally diprotected alpha-hydrazino acids 1 is developed on a multigram scale. The key reaction is the efficient electrophilic amination of N-benzyl amino acids 6 with N-Boc-oxaziridine 7 and accommodates various functional groups encountered in side chains of amino acids. The cyclic 2,3,4,5-tetrahydro-3-pyridazine carboxylic acid (piperazic acid) derivatives 2 and 3 or the cyclic 3,4-dihydro-3-pyrazolecarboxylate 4 are conveniently prepared from glutamic acid or aspartic acid via orthogonally diprotected alpha-hydrazino acids 1m and 1n.

Abstract
In order to further examine the properties of pseudopeptides containing the 2-hydrazonoacyl fragment, two new series of analogs of the prototypical chemotactic N-formyl-tripeptide HCO-Met-Leu-Phe-OMe were designed and synthesized. The first group contains the new fragment as the N-terminal residue and is represented by the N-aryl derivatives p-Cl-C6H4-NH-N=C(R)-CO-Leu-Phe-OMe (2 and 3) and by the corresponding N-aroyl analogs p-CH3-C6H4-CO-NH-N=C(R)-CO-Leu-Phe-OMe (4). The second group contains the new fragment in place of the central Leu residue and is represented by compounds HCO-Xaa-NH-N=C(R)-CO-Phe-OMe (7a and 7b) where Xaa is Nle and Met, respectively. The conformational and biochemical properties of the new products were examined.

Abstract
Replacing the C(beta) atoms in the beta-amino acid constituents of beta-peptides by nitrogen atoms leads to hydrazino peptides. A systematic conformation analysis of blocked hydrazino peptide oligomers of the general type I at the HF/6-31G, MP2/6-31G, and DFT/B3LYP/6-31G levels of ab initio MO theory and on the basis of molecular mechanics reveals a wide variety of secondary structures, as for instance various helices and sheet- and turnlike conformers. Some of them are closely related to secondary structure types found in beta-peptides; others represent novel types. Thus, a very stable, novel helix with 14-membered hydrogen-bonded pseudocycles, which occupies a conformation space different from that of helices with 14-membered rings found among the most stable conformers in beta-peptides, is indicated. The most important secondary structure elements are characterized by interactions between peptidic NH and CO groups. The additional hydrazino N(alpha)H group takes part in special structuring effects but is of lesser importance for secondary structure formation. The influence of environmental effects on the existence and stability of the various structure types is discussed. Due to the wide variety of structural possibilities, hydrazino peptides might be a useful tool for peptide and protein design.

Abstract
In order to obtain chemotactic peptides with selective bioactivity, a new type of structural modification was introduced at the N-terminal position of HCO-Nle-Leu-Phe-OMe. Two groups of analogs have been synthesized both containing a N-terminal residue of the X=C(R)-CO-type replacing the native HCO-NH-CH(R)-CO-. In particular, the A group of pseudopeptides (2a-d) possesses a N-terminal oximic fragment (X=HO-N) and the B group (3a-d) a formylhydrazone fragment (X=HCO-NH-N). These new ligands have been examined for their capacity to induce chemotaxis and other cellular responses such as superoxide anion production and lysozyme release; although significantly active as chemoattractants they have been found to be practically devoid of secretagog activity, thus exhibiting selective behavior. The adopted chemical modification seems extensible in designing a new class of pseudopeptides (hydrazonopeptides) structurally related to both hydrazinopeptides and peptides containing alpha,beta-unsaturated residues.

Abstract
The synthesis of hydrazinopeptides using solid-phase N-electrophilic amination was extended to the Fmoc/tert-butyl strategy. Both Boc/benzyl and Fmoc/tert-butyl strategies led to the isolation of by-products arising from the partial instability of the N-N bond during the final cleavage and deprotection step. Two paths of decomposition have been shown: the cleavage of the N-N bond leading to the regeneration of the amine and a Hofmann-type elimination yielding original dianisyl adducts. Our data suggest that the Fmoc/tert-butyl strategy is better suited for the synthesis of hydrazinopeptides.

Abstract
Lys(NH2)-containing peptides were subjected to various proteolytic enzymes which were selected for their well-documented specificity for arginyl and/or lysyl peptide bonds. Lys(NH2)-containing peptides were cleaved more rapidly by clostripain than the corresponding lysyl peptides. On the other hand, they proved to be resistant to Achromobacter protease I hydrolysis. The modified peptides synthesized in this study were more stable than the arginyl and lysyl analogues when incubated with trypsin or thrombin. The same tendency was observed when Lys(NH2)-containing peptides were incubated in diluted human serum, suggesting that the replacement of Arg or Lys by Lys(NH2) could be used to increase the stability of peptides in vivo.

Abstract
The name hydrazinopeptide designates peptidic structures in which one of the native CONH links is replaced by a CONHNH (hydrazido) fragment. In this paper, we report the synthesis of such hydrazinohexapeptides (3-5) analogous to Z-Ala-Ala-Pro-Val-Ala-Ala-NHiPr (6), a substrate of human leukocyte elastase (HLE; EC 3.4.21.37), cleaved by this serine protease between the Val4 and Ala5 residues. In hydrazinopeptides 3-5, the Ala5, Val4, or Pro3 residue, respectively, of the model peptide, has been replaced by the corresponding alpha-L-hydrazino acid. In 3, the bond likely to be cleaved by HLE is the one involving the CONHNH link, while in 4 and 5, this link is normally shifted away by one or two amino acid units from the catalytic serine. On incubation with HLE, hydrazinopeptide 3 proved to be a substrate and was cleaved between Val4 and NHAla5, like peptide 6. In contrast, 4 and 5 proved to bind to HLE without being cleaved, featuring properties consistent with reversible competitive inhibition. General guidelines for the synthesis of hydrazinopeptides are also reported in this paper. These guidelines take into account the chemical specificity of hydrazino acids, while being fully compatible with the conventional peptide coupling techniques. The utilization of orthogonally bisprotected hydrazino acids 1 where the Nbeta and Nalpha atoms bear a Boc and a Bzl group, respectively, is recommended for the easy construction of such hydrazinopeptides.

Abstract
In this paper we report that a hydrazinopeptide synthesized using solid-phase N-electrophilic amination with N-Boc-3-(4-cyanophenyl)oxaziridine reacted with a lipophilic peptide aldehyde to give the corresponding hydrazone plus an unexpected 1,3,4-oxadiazolidinopeptide containing two peptide aldehyde units. This methodology allows the synthesis of large lipopeptides.

Abstract
The X-ray diffraction experiments on peptides and related molecules which have been carried out in Western Europe, except Italy, in the last eight years are reviewed. The crystal structures of some bioactive peptides such as Leu-enkephalin (a neurotransmitter), cyclosporin A (an immunomodulator in both the free and protein-bound state), balhimycin (an antibiotic) and octreotide (a somatostatin analogue) are briefly presented. Crystallized N- and C-protected model peptides have given an insight into the folding tendency and folding modes depending on the peptide sequences. The crystal structures of various pseudopeptide molecules reveal how the three-dimensional structure of peptide analogues can be modulated by substituting non-peptide groups for the peptide bond. A few examples of structural mimetics of the beta- and gamma-turns, and of templates for alpha-helix induction are also presented.

Abstract
The folded structure induced by the N-aminoproline residue (the hydrazino analogue of proline, denoted hPro) in the Boc-Gly1-hPro2-Gly3-NHiPr hydrazino tripeptide has been characterized in the solid state by X-ray diffraction, and compared to the usual beta II-turn structure in the Boc-Gly1-Pro2-Gly36-NHiPr cognate tripeptide. It is stabilized by a bifurcated hydrogen bond in which (Gly3)NH interacts with both (Gly1)CO and (hPro2)N alpha. This conformation is retained in CH2Cl2 and CHCl3 solutions, and allows an overall folded conformation of the hydrazino tripeptide in which (iPr)NH is hydrogen-bonded to (Boc)CO. The hPro alpha-hydrazino acid residue appears to promote a local folded structure, and might behave as a beta-turn mimic.
