Abstract
This review covers the recent advances in the development of small RGD (Arg-Gly-Asp sequence) containing peptides and their mimetics as potential antithrombotic agents. Glycoprotein IIb/IIIa (GPIIb/IIIa) antagonists include monoclonal antibodies, RGD peptides, peptide hybrids and nonpeptide mimetics. The current trend in the development of nonpeptide mimetics is clearly directed toward orally active and safe antithrombotic drug candidates. But several nonpeptide mimetics, being evaluated for their oral activity in human clinical trials, are currently not approved for clinical use due to poor safety profile. It is expected that newer and more effective nonpeptide mimetics will be developed in the near future.

Abstract
Six new endomorphin analogues, incorporating constrained amino acids in place of native proline have been synthesized. Residues of (S)-azetidine-2-carboxylic acid (Aze), 3,4-dehydro-(S)-proline (Delta(3)Pro), azetidine-3-carboxylic acid (3Aze) and dehydro-alanine (DeltaAla) have been used to prepare [Delta(3)Pro(2)]EM-2 (1), [Aze(2)]EM-1 (2), [Aze(2)]EM-2 (3), [3Aze(2)]EM-1 (4), [3Aze(2)]EM-2 (5) and [DeltaAla(2)]EM-2 (6). Binding assays and functional bioactivities for mu- and delta-receptors are reported. The highest affinity, bioactivity and selectivity are shown by peptides 2 and 3 containing the Aze residue.

Abstract
Immune response suppressors are used in the medical praxis to prevent graft rejection after organ transplantation and in the therapy of some autoimmune diseases. As a continuation of our previous work searching for new, effective suppressors devoid of toxicity, we present the synthesis, conformational analysis, and biological activity of nonapeptides 1-6, analogs of naturally existing immunomodulatory peptide CLA. New CLA analogs were modified with (S)-beta(2)-iso-proline 7 or (S)-beta(3)-homo-proline 8, respectively. The conformational influence of the beta-iso-proline and beta-homo-proline building blocks was analyzed by NMR spectroscopy. Peptides 1-6 exist as a mixture of four isomers due to cis/trans isomerization of the Xxx-Pro peptide bond. The major isomers of peptides 1, 3, and 4 contain all peptide bonds of the trans geometry. The geometry of the proline-proline bond of the second populated isomer of peptides 3 and 4 is cis. The proline-proline peptide bond is cis for the major isomers of peptides 2, 5, and 6. The peptides were tested for their ability to suppress the proliferative response of mouse splenocytes to T- and B-cell mitogens and the secondary humoral immune response to sheep erythrocytes in vitro in parallel with a reference drug-cyclosporine A. The immunoregulatory actions of the peptides depended on the position and content of proline isomers and were, with some exceptions, strongly inhibitory at the highest dose tested (100 microg/ml). In addition, the peptides were practically devoid of toxicity at that dose. In conclusion, the replacement of Pro by beta-Pro may be useful for fine-tuning CLA immunosuppressive potency and undesirable toxicity.

Abstract
[reaction: see text] We have recently shown that members of a new class of beta-peptides, containing 2,2-disubstituted pyrrolidine-4-carboxylic acid residues, display discrete conformational preferences despite the impossibility of internal hydrogen bonding (Huck et al. J. Am. Chem. Soc. 2003, 125, 9035). Here we describe the synthesis of a variety of 2,2-disubstituted pyrrolidine-4-carboxylic derivatives that bear a diverse set of side chains and protecting groups suitable for oligomer synthesis. In addition, we discuss coupling methods for construction of oligomers in solution and on solid phase. Non-hydrogen bonded foldamers such as those generated from 2,2-disubstituted pyrrolidine-4-carboxylic acids may be useful in biomedical applications because the low intrinsic polarity of their backbones may promote bioavailability.

Abstract
Although they are less abundant than their alpha-analogues, beta-amino acids occur in nature both in free form and bound to peptides. Oligomers composed exclusively of beta-amino acids (so-called beta-peptides) might be the most thoroughly investigated peptidomimetics. Beside the facts that they are stable to metabolism, exhibit slow microbial degradation, and are inherently stable to proteases and peptidases, they fold into well-ordered secondary structures consisting of helices, turns, and sheets. In this respect, the most intriguing effects have been observed when beta2-amino acids are present in the beta-peptide backbone. This review gives an overview of the occurrence and importance of beta2-amino acids in nature, placing emphasis on the metabolic pathways of beta-aminoisobutyric acid (beta-Aib) and the appearance of beta2-amino acids as secondary metabolites or as components of more complex natural products, such as peptides, depsipeptides, lactones, and alkaloids. In addition, a compilation of the syntheses of both achiral and chiral beta2-amino acids is presented. While there are numerous routes to achiral beta2-amino acids, their EPC synthesis is currently the subject of many investigations. These include the diastereoselective alkylation and Mannich-type reactions of cyclic- or acyclic beta-homoglycine derivatives containing chiral auxiliaries, the Curtius degradation, the employment of transition-metal catalyzed reactions such as enantioselective hydrogenations, reductions, C-H insertions, and Michael-type additions, and the resolution of rac. beta2-amino acids, as well as several miscellaneous methods. In the last part of the review, the importance of beta2-amino acids in the formation of beta-peptide secondary structures is discussed.

Abstract
Endomorphin-1 (Tyr-Pro-Trp-PheNH2) has been proposed as the most potent endogenous ligand of the mu-opioid receptors. In this paper, we describe the synthesis of some endomorphin-1 based tetrapeptides in which a residue of the sequence Tyr-Pro-Trp-PheNH2 is replaced by the corresponding beta-isomer. These novel peptides showed different affinities for the opioid receptors labeled with [3H]-DAMGO in rat brain membranes, depending on the beta-amino acid. In particular, the tetrapeptide containing beta-Pro (Tyr-beta-(R)-Pro-Trp-PheNH2) displayed a higher affinity than endogenous endomorphin-1, as revealed by their Ki values (0.33 and 11.1 nM, respectively).

Abstract
A decamer of a beta-amino acid analogue of L-proline, (3R)-carboxy pyrrolidine (beta-proline), was synthesized from a readily available (R)-glycidol. It was found to possess a rigid secondary structure, as evidenced by its CD spectrum. The beta-proline decamer, however, failed to bind to profilin, whereas the corresponding alpha-L-proline decamer bound tightly to this protein.

Abstract
[formula: see text] Homooligomers of beta-amino acids (S)-3-pyrrolidine-3-carboxylic acid (PCA) and (S)-nipecotic acid (Nip) were studied by circular dichroism (CD) in methanol. In each series, a profound change in the far-UV CD spectrum was observed from monomer to tetramer, but little change was observed from tetramer to hexamer. A comparable pattern is observed in the CD spectra of short proline oligomers. We conclude that both PCA and Nip oligomers with > or = four residues adopt a characteristic secondary structure.
