Abstract
Despite their concomitant emergence in the 1990s, γ-peptide foldamers have not developed as fast as β-peptide foldamers and to date, only a few γ-oligomer structures have been reported, and with sparse applications. Among these examples, sequences containing α,β-unsaturated γ-amino acids have recently drawn attention since the Z/E configurations of the double bond provide opposite planar restrictions leading to divergent conformational behaviors, from helix to extended structures. In this Review, we give a comprehensive overview of the developments of γ-peptide foldamers containing α,β-unsaturated γ-amino acids with examples of applications for health and catalysis, as well as materials science.

Diversity, molecular mechanisms and structure-activity relationships of marine protease inhibitors-A review. Pharmacol Res 2021; 166:105521.

Abstract
Marine habitats are well-known for their diverse life forms that are potential sources of novel bioactive compounds. Evidence from existing studies suggests that these compounds contribute significantly to the field of pharmaceuticals, nutraceuticals, and cosmeceuticals. The isolation of natural compounds from a marine environment with protease inhibitory activity has gained importance due to drug discovery potential. Despite the increasing research endeavours focusing on protease inhibitors' design and characterization, many of these compounds have failed to reach final phases of clinical trials. As a result, the search for new sources for the development of protease inhibitors remains pertinent. This review focuses on the diverse marine protease inhibitors and their structure-activity relationships. Furthermore, the potential of marine protease inhibitors in drug discovery and molecular mechanism inhibitor binding are critically discussed.

Abstract
Many proteins exert their biological activities through small exposed surface regions called epitopes that are folded peptides of well-defined three-dimensional structures. Short synthetic peptide sequences corresponding to these bioactive protein surfaces do not form thermodynamically stable protein-like structures in water. However, short peptides can be induced to fold into protein-like bioactive conformations (strands, helices, turns) by cyclization, in conjunction with the use of other molecular constraints, that helps to fine-tune three-dimensional structure. Such constrained cyclic peptides can have protein-like biological activities and potencies, enabling their uses as biological probes and leads to therapeutics, diagnostics and vaccines. This Review highlights examples of cyclic peptides that mimic three-dimensional structures of strand, turn or helical segments of peptides and proteins, and identifies some additional restraints incorporated into natural product cyclic peptides and synthetic macrocyclic peptidomimetics that refine peptide structure and confer biological properties.

Abstract
A short, convergent, formal total synthesis of cyclotheonamide C is described. The key linear pentapeptide intermediate is assembled at the same time as the elaboration of the alpha-hydroxyhomoarginine (H-hArg) residue via a three-component Passerini reaction-amine deprotection-O,N-acyl migration strategy.

Abstract
Serine protease enzymes use a serine hydroxyl group to catalyze hydrolysis of polypeptides. They are important in immunity, blood clotting, digestion, and as therapeutic or diagnostic targets for cancer, diabetes, stroke, inflammatory diseases, and viral infections. Their inhibitors typically possess an electrophile that reacts with the nucleophilic hydroxyl group of the catalytic serine. The α-ketoamide is a valuable electrophile in inhibitor discovery as it permits synthetic elaboration to both sides, unlike other electrophiles. Here we show that an α-ketoamide is unstable above pH 7 when adjacent to the C-terminus of arginine – the guanidine side chain condenses with the α-ketoamide at the keto group rather than the amide carbonyl to form a six-membered hemiaminal rather than a seven-membered lactam.

Abstract
Hookworms are hematophagous nematodes capable of growth, development and subsistence in living host systems such as humans and other mammals. Approximately one billion, or one in six, people worldwide are infected by hookworms causing gastrointestinal blood loss and iron deficiency anemia. The hematophagous hookworm Ancylostoma caninum produces a family of small, disulfide-linked protein anticoagulants (75-84 amino acid residues). One of these nematode anticoagulant proteins, NAP5, inhibits the amidolytic activity of factor Xa (fXa) with K(i)=43 pM, and is the most potent natural fXa inhibitor identified thus far. The crystal structure of NAP5 bound at the active site of gamma-carboxyglutamic acid domainless factor Xa (des-fXa) has been determined at 3.1 A resolution, which indicates that Asp189 (fXa, S1 subsite) binds to Arg40 (NAP5, P1 site) in a mode similar to that of the BPTI/trypsin interaction. However, the hydroxyl group of Ser39 of NAP5 additionally forms a hydrogen bond (2.5 A) with His57 NE2 of the catalytic triad, replacing the hydrogen bond of Ser195 OG to the latter in the native structure, resulting in an interaction that has not been observed before. Furthermore, the C-terminal extension of NAP5 surprisingly interacts with the fXa exosite of a symmetry-equivalent molecule forming a short intermolecular beta-strand as observed in the structure of the NAPc2/fXa complex. This indicates that NAP5 can bind to fXa at the active site, or the exosite, and to fX at the exosite. However, unlike NAPc2, NAP5 does not inhibit fVIIa of the fVIIa/TF complex.

Abstract
Marine invertebrates are rich sources of small molecules with unique chemical skeletons and potent bioactivities. Historically, such compounds were discovered mainly through the use of assays for phenotype-oriented activities, such as cytotoxicity or antimicrobial effects. More recently, target-oriented searches for bioactive substances, as exemplified by enzyme inhibitors, have become much more common, given a growing need for small-molecule inhibitors essential for studies of complex processes at the interface of chemistry and biology. In this review, selected enzyme inhibitors from marine invertebrates are presented.

Abstract
The large variety of serine protease inhibitors, available from various sources such as tissues, microorganisms, plants, etc., play an important role in regulating the proteolytic enzymes. The analysis of protease-inhibitor complexes helps in understanding the mechanism of action, as well as in designing inhibitors. Vasopressin, an anti-diuretic nonapeptide hormone, is found to be an effective inhibitor of trypsin, with a K(i) value of 5 nM. The crystal structure of the trypsin-vasopressin complex revealed that vasopressin fulfils all the important interactions for an inhibitor, without any break in the scissile peptide bond. The cyclic nature due to a disulfide bridge between Cys1 and Cys6 of vasopressin provides structural rigidity to the peptide hormone. The trypsin-binding site is located at the C terminus, while the neurophysin-binding site is at the N terminus of vasopressin. This study will assist in designing new peptide inhibitors. This study suggests that vasopressin inhibition of trypsin may have unexplored biological implications.

Abstract
Tryptase is a protease released from mast cells and is believed to contribute to the inflammatory process in allergic diseases including asthma. In the course of screening to find tryptase inhibitors, we isolated two new tryptase inhibitors, cyclotheonamide E4 (3) and E5 (4), from a marine sponge of the genus Ircinia. The structures of these molecules were determined by interpretation of 1H and 13C NMR spectra, and they were shown to be closely related to the previously reported cyclotheonamides E (1), E2, and E3 (2). These molecules contain two unusual amino acids, vinylogous tyrosine and alpha-ketohomoarginine, which are involved in strong activities against serine proteases. Cyclotheonamide E4 showed potent inhibitory activity against human tryptase (IC50 5.1 nM). Therefore, cyclotheonamide E4 may be useful as a therapeutic agent in the treatment of allergic diseases including asthma.

Abstract
A large number of potent and selective therapeutic agents, useful for the treatment of several diseases, have been isolated from natural sources. For example, the most active thrombin inhibitors are those secreted by the salivary glands of leeches. One peculiar feature of these agents is the lack of any significant inhibitory cross-reaction with other serine proteinases. Hence, the knowledge of the exact mechanism of action of these molecules provides the basis for the development of new and efficient synthetic drugs. For this reason, many studies have been undertaken on the structure-activity relationships of natural thrombin inhibitors, and a large amount of detailed information has been obtained by the crystal structures of these inhibitors when complexed with thrombin. In this paper, we review natural and synthetic multisite thrombin inhibitors, whose structural aspects have been determined in detail. We also report here the approach used by us to develop a new class of synthetic, multisite directed thrombin inhibitors, named hirunorms, designed to mimic the distinctive binding mode of hirudin.

Abstract
Proteinaceous serine proteinase inhibitors are widespread throughout the plant kingdom where they play an important role in protection against pests and pathogens. Here, we describe the isolation and characterisation of a novel 14 amino acid residue cyclic peptide from sunflower seeds, which is a potent inhibitor of trypsin (Ki=100 pM). The crystal structure of this peptide in complex with bovine beta-trypsin shows both sequence and conformational similarity with the trypsin-reactive loop of the Bowman-Birk family of serine proteinase inhibitors. This inhibitor, however, is unique in being monofunctional, cyclic and far shorter (14 amino acid residues) than inhibitors belonging to this family (typically 60-70 amino acid residues). The high potency of this peptide is likely to arise from the considerable structural rigidity achieved through its cyclic nature which is further stabilised by a single internal disulphide bond. This study helps delineate the minimal unit required for effective peptide inhibitors of serine proteinases, and will assist in the further design of inhibitors to this widespread class of enzymes.

Abstract
The X-ray crystal structures of four beta-strand-templated active site inhibitors of thrombin containing P1' groups have been determined and refined at about 2.1-A resolution to crystallographic R-values between 0.148 and 0.164. Two of the inhibitors have an alpha-ketoamide functionality at the scissile bond; the other two have a nonhydrolyzable electrophilic group at the P1' position. The binding of lysine is compared with that of arginine at the S1 specificity site, while that of D,L-phenylalanine enantiomorphs is compared in the S3 region of thrombin. Four different P1' moieties bind at the S1' subsite in three different ways. The binding constants vary between 2.0 microM and 70 pM. The bound structures are used to intercorrelate the various binding constants and also lead to insightful inferences concerning binding at the S1' site of thrombin.

Abstract
The event that initiates the extrinsic pathway of blood coagulation is the association of coagulation factor VIIa (VIIa) with its cell-bound receptor, tissue factor (TF), exposed to blood circulation following tissue injury and/or vascular damage. The natural inhibitor of the TF.VIIa complex is the first Kunitz domain of tissue factor pathway inhibitor (TFPI-K1). The structure of TF. VIIa reversibly inhibited with a potent (Ki=0.4 nM) bovine pancreatic trypsin inhibitor (BPTI) mutant (5L15), a homolog of TFPI-K1, has been determined at 2.1 A resolution. When bound to TF, the four domain VIIa molecule assumes an extended conformation with its light chain wrapping around the framework of the two domain TF cofactor. The 5L15 inhibitor associates with the active site of VIIa similar to trypsin-bound BPTI, but makes several unique interactions near the perimeter of the site that are not observed in the latter. Most of the interactions are polar and involve mutated positions of 5L15. Of the eight rationally engineered mutations distinguishing 5L15 from BPTI, seven are involved in productive interactions stabilizing the enzyme-inhibitor association with four contributing contacts unique to the VIIa.5L15 complex. Two additional unique interactions are due to distinguishing residues in the VIIa sequence: a salt bridge between Arg20 of 5L15 and Asp60 of an insertion loop of VIIa, and a hydrogen bond between Tyr34O of the inhibitor and Lys192NZ of the enzyme. These interactions were used further to model binding of TFPI-K1 to VIIa and TFPI-K2 to factor Xa, the principal activation product of TF.VIIa. The structure of the ternary protein complex identifies the determinants important for binding within and near the active site of VIIa, and provides cogent information for addressing the manner in which substrates of VIIa are bound and hydrolyzed in blood coagulation. It should also provide guidance in structure-aided drug design for the discovery of potent and selective small molecule VIIa inhibitors.

Abstract
Two new potent serine protease inhibitors, cyclotheonamides E2 (3) and E3 (4), have been isolated from a marine sponge of the genus Theonella. Their structures were determined by interpretation of spectral data and chemical degradation studies. They are closely related to the previously reported cyclotheonamide E, from which they differ in the N-acyl group of the alanyl side chain. Cyclotheonamides E, E2, and E3 were more active against thrombin than against trypsin.
