Abstract
α-Amanitin is a bicyclic octapeptide composed of a macrolactam with a tryptathionine cross-link forming a handle. Previously, the occurrence of isomers of amanitin, termed atropisomers has been postulated. Although the total synthesis of α-amanitin has been accomplished this aspect still remains unsolved. We perform the synthesis of amanitin analogs, accompanied by in-depth spectroscopic, crystallographic and molecular dynamics studies. The data unambiguously confirms the synthesis of two amatoxin-type isomers, for which we propose the term ansamers. The natural structure of the P-ansamer can be ansa-selectively synthesized using an optimized synthetic strategy. We believe that the here described terminology does also have implications for many other peptide structures, e.g. norbornapeptides, lasso peptides, tryptorubins and others, and helps to unambiguously describe conformational isomerism of cyclic peptides.

Abstract
Mechanically chiral molecules have attracted considerable attention due to their property and function based on its unique interlocked structure. This review covers the recent advances in the synthesis and function of interlocked rotaxanes with mechanical chirality along with their dynamic and complex stereochemistry. The application of mechanically chiral rotaxanes to control the polymer helical structure is also introduced, where amplification of mechanical chirality appears to cause the macroscopic polymer property change, suggesting the potential applicability of mechanical chirality in polymer systems.

Abstract
An emerging and attractive target for the treatment of Alzheimer's disease is to inhibit the aggregation of beta-amyloid protein (Abeta). We applied the retro-enantio concept to design an N-methylated peptidic inhibitor of the Abeta42 aggregation process. This inhibitor, inrD, as well as the corresponding all-L (inL) and all-D (inD) analogues were assayed for inhibition of Abeta42 aggregation. They were also screened in neuroblastoma cell cultures to assess their capacity to inhibit Abeta42 cytotoxicity and evaluated for proteolytic stability. The results reveal that inrD and inD inhibit Abeta42 aggregation more effectively than inL, that inrD decreases Abeta42 cytotoxicity to a greater extent than inL and inD, and that as expected, both inD and inrD are stable to proteases. Based on these results, we propose that the retro-enantio approach should be considered in future designs of peptide inhibitors of protein aggregation.

Abstract
Hemophilia A, one of the most severe bleeding disorders, results from an inherited deficiency of factor VIII (FVIII) function. Treatment by injection of FVIII has been a common procedure for decades. Nevertheless, the production and purification of FVIII remains a challenging task. Current procedures using immunoaffinity chromatography are expensive and suffer from the instability of the applied antibody ligands, which elute along with the product and contaminate it. Recently, FVIII was purified by use of octapeptide ligands, but their low protease-resistance limits their application. We here report the systematic rational and combinatorial optimization procedure that allowed us to transfer the octapeptide ligands into a small peptidomimetic. This compound is the smallest ligand known for separation of such a large protein (330 kDa). It not only binds and purifies FVIII with high efficiency but also is stable, protease-resistant, and cheap to produce in preparative scale. Hence it offers a valuable alternative to antibody-based purification procedures.

Abstract
Azumamide E, a cyclotetrapeptide isolated from the sponge Mycale izuensis, is the most powerful carboxylic acid containing natural histone deacetylase (HDAC) inhibitor known to date. In this paper, we describe design and synthesis of two stereochemical variants of the natural product. These compounds have allowed us to clarify the influence of side chain topology on the HDAC-inhibitory activity. The present contribution also reveals the identity of the recognition pattern between azumamides and the histone deacetylase-like protein (HDLP) model receptor and reports the azumamide E unprecedented isoform selectivity on histone deacetylases class subtypes. From the present studies, a plausible model for the interaction of azumamides with the receptor binding pocket is derived, providing a framework for the rational design of new cyclotetrapeptide-based HDAC inhibitors as antitumor agents.

Abstract
A [2]catenane in which the macrocyclic polyether, bisparaphenylene[34]crown-10, is interlocked with the tetracationic cyclophane, cyclobis(paraquat-p-phenylene), is shown by dynamic (1)H NMR spectroscopy, using (i). neutral and (ii). anionic chiral shift reagents (CSRs), to exist at low temperatures (197 K) in acetone-d(6) solutions as 1:1 and 2:1 mixtures of diastereoisomeric complexes and salts, respectively, as a consequence of the helical chirality associated with the [2]catenane interacting with the CSRs.

Abstract
The syntheses of the host-selective phytotoxin destruxin B [cyclo(betaAla-Hmp-Pro-Ile-MeVal-MeAla), Hmp = (2R)-2-hydroxy-4-methylpentanoic acid], and the closely related natural analogues homodestruxin B (MeVal-->MeIle), desmethyldestruxin B (MeVal-->Val), hydroxydestruxin B (Hmp-->Dhmp, Dhmp = (2R)-2,4-dihydroxy-4-methylpentanoic acid), and hydroxyhomodestruxin B (MeVal-->MeIle, Hmp-->Dhmp) are described. In each case, the MeAla-betaAla linkage was formed by cyclization and the precursor linear hexadepsipeptides were formed by condensing two three-residue fragments. Radiolabeled samples of destruxin B, homodestruxin B, and hydroxydestruxin B were prepared by coupling [3-(14)C]-beta-alanine to the appropriate pentadepsipeptide followed by cyclization. A noteworthy feature of the synthesis involves the novel use of a Boc-hydrazide protecting group on dipeptides with a C-terminal N-methylalanine residue to inhibit the otherwise facile dioxopiperazine formation during peptide coupling.

Abstract
The synthesis and characterization of novel metallocavitand 6 are described. This is a covalent hybrid of a deepened, self-folding cavity and a Zn-phenanthroline fragment. Host 6 features a large molecular cavity of approximately 8 x 10 A dimensions, and the metal binding site is directed in toward the cavity. Binding abilities of the metallocavitand in solution was demonstrated for quinuclidine 11 and Dabco 12 using UV-vis and 1H NMR spectroscopy. Intramolecular hydrogen bonds at the upper rims of cavitand 6 resist the unfolding of the inner cavities and thereby increase the energetic barrier to guest exchange. The exchange is slow on the NMR time scale (at ambient temperatures, CD2Cl2), and kinetically stable complexes result. Both the polyaromatic cavity and metallosite participate simultaneously in the binding event. Zinc-containing deep cavities may be attractive as catalytic chambers for hydrolysis and esterification.

Abstract
The synthesis and characterization of new nanoscale container molecules 7 and 8 are described. They are covalent hybrids of deepened, self-folding cavitands and metalloporphyrins. In receptor 7, the Zn-porphyrin wall is directly built onto the cavitand skeleton. Host 8 features a large unimolecular cavity containing two cavitands attached with the Zn-porphyrin wall. Its dimensions, approximately 10 x 25 A, place it among the largest synthetic hosts prepared to date. A series of adamantyl- and pyridyl-containing guests 14-20 of various lengths were prepared and used to determine the hosts' binding abilities in solution using UV/vis and (1)H NMR spectroscopy. Intramolecular hydrogen bonds at the upper rims of the cavitands resist the unfolding of the inner cavities and thereby increase the energetic barrier to guest exchange. The exchange is slow on the NMR time scale (at < or =300 K), and kinetically stable complexes result. When the cavities and metalloporphyrins participate simultaneously in the binding event, very high affinities for guests are found (-DeltaG295 up to 10 kcal x mol(-1) in toluene), to which the porphyrin fragments contribute significantly (-DeltaG295 up to 6 kcal x mol(-1)). The pairwise selection of two different guests by molecular container 8 is reported, and the termolecular complex formed raises the possibility of metal-catalyzed bimolecular reactions in these containers.

Abstract
A new type of [1]rotaxanes containing two aliphatic bridges between axle and wheel is obtained in 39% yield in a one-step synthesis starting from a [2]rotaxane which contained one sulfonamide group each in both the wheel and the axle. Temperature controlled chemoselective substitution reactions first at these sulfonamide nitrogens and then subsequently at the various other carboxamide nitrogens in the wheel and axle give rise to the formation of an isomeric mixture of three double-bridged [1]rotaxanes which could be separated by HPLC. Structure determination of the main product 3a was possible by NMR experiments supported by molecular modeling calculations. Using different reaction conditions, a double-substituted but not yet bridged [2]rotaxane 4 could be isolated as an intermediate giving further evidence for the assigned structure of 3a and the way of its formation. The shape of this double-bridged [1]rotaxane 3a reminds of a self-intertwining chiral "molecular 8", in which any possible racemization due to deslipping is hindered by the two stoppers originating from the former rotaxane axle. Hence, to the best of our knowledge this is the first example of a molecule in which both concepts, cycloenantiomerism and helical chirality, are realised in one structure. Enantiomer separation of the main product was possible by further HPLC using chiral stationary phases. The Cotton effects of the circular dichrograms are different to those of the already synthesized [1]rotaxanes bearing just one aliphatic bridge between axle and wheel.

Abstract
Cycloenantiomeric hexahomooxacalix[3]arenes with different substituents on the three upper rims were synthesized for the first time by fixing their conformation into a cone. A cycloenantiomeric hexahomooxacalix[3]arene 6 was resolved into both enantiomeric forms and chiroptically characterized. Preliminary 1H-NMR studies indicated that the optically resolved cycloenantiomer 6 could discriminate the enantiomers of hydrochloride of phenylalanine ethyl ester.

Abstract
The first segments of this article review some of the early crystal structure determinations of beta-bends, gamma-bends, large conformational changes in cyclic peptides upon complexation with metal ions, and both the stability and drastic change in conformation as a function of the solvent used for growing crystals. More recent structure analyses have concerned helical peptides containing the Aib and/or Dpg residues and associated conformational problems such as 310-/alpha-helix transitions, helix aberrations, reversals, severe curving of the helix, unfolding, and hydration of backbone. Ion channels occurring in three crystal forms of zervamicin and possible ion transport and gating mechanisms are described. Finally, hydrogen bonding patterns are presented in supramolecular assemblies of retropeptides with core inserts consisting of oxalyl, adipoyl, suberoyl and polymethylene moieties.

Abstract
Main-chain peptidomimetics based on peptide-bond reversal and inversion of chirality represent important structural alterations for peptides and proteins, and are highly significant for biotechnology; these modifications have been widely applied: the D-HIV-protease dimer cleaves only all-D substrate; an all-D-hexapeptide opioid is able to produce analgesia following intraperitoneal administration. Antigenicity and immunogenicity can be achieved by metabolically stable antigens such as all-D- and retro-inverso-isomers of natural antigenic peptides. Isomers, including the retro- and retro-inverso- forms, of hybrid peptides derived from cercropin A and melittin, maintain antimicrobial activity. Therefore, an insight is provided into structure-activity relationships and the rational design of biologically important isomeric peptides.
