Abstract
Cyclic and macrocyclic peptides constitute advanced molecules for modulating protein-protein interactions (PPIs). Although still peptide derivatives, they are metabolically more stable than linear counterparts, and should have a lower degree of flexibility, with more defined secondary structure conformations that can be adapted to imitate protein interfaces. In this review, we analyze recent progress on the main methods to access cyclic/macrocyclic peptide derivatives, with emphasis in a few selected examples designed to interfere within PPIs. These types of peptides can be from natural origin, or prepared by biochemical or synthetic methodologies, and their design could be aided by computational approaches. Some advances to facilitate the permeability of these quite big molecules by conjugation with cell penetrating peptides, and the incorporation of β-amino acid and peptoid structures to improve metabolic stability, are also commented. It is predicted that this field of research could have an important future mission, running in parallel to the discovery of new, relevant PPIs involved in pathological processes.

Abstract
Autotaxin (ATX), a glycoprotein (~125 kDa) isolated as an autocrine motility factor from melanoma cells, belongs to a seven-membered family of ectonucleotide pyrophosphatase/phosphodiesterase (ENPP), and exhibits lysophospholipase D activity. ATX is responsible for the hydrolysis of lysophosphatidylcholine (LPC) to produce the bioactive lipid lysophosphatidic acid (LPA), which is upregulated in a variety of pathological inflammatory conditions, including fibrosis, cancer, liver toxicity and thrombosis. Given its role in human disease, the ATX-LPA axis is an interesting target for therapy, and the development of novel potent ATX inhibitors is of great importance. In the present work a novel class of ATX inhibitors, optically active derivatives of 2-pyrrolidinone and pyrrolidine heterocycles were synthesized. Some of them exhibited interesting in vitro activity, namely the hydroxamic acid 16 (IC50 700 nM) and the carboxylic acid 40b (IC50 800 nM), while the boronic acid derivatives 3k (IC50 50 nM), 3l (IC50 120 nM), 3 m (IC50 180 nM) and 21 (IC50 35 nM) were found to be potent inhibitors of ATX.

Abstract
Expanding the genetic code of organisms by incorporating noncanonical amino acids (ncAAs) into target proteins through the suppression of stop codons in vivo has profoundly impacted how we perform protein modification or detect proteins and their interaction partners in their native environment. Yet, with genetic code expansion strategies maturing over the past 15 years, new applications that make use—or indeed repurpose—these techniques are beginning to emerge. This Concept article highlights three of these developments: 1) The incorporation of ncAAs for the biosynthesis and selection of bioactive macrocyclic peptides with novel ring architectures, 2) synthetic biocontainment strategies based on the addiction of microorganisms to ncAAs, and 3) enzyme design strategies, in which ncAAs with unique functionalities enable the catalysis of new‐to‐nature reactions. Key advances in all three areas are presented and potential future applications discussed.

Abstract
Semisynthetic cyclic peptides containing both non-proteinogenic building blocks, as the synthetic part, and a genetically encoded sequence amenable to DNA-based randomization hold great potential to expand the chemical space in the quest for novel bioactive peptides. Key to an efficient selection of novel binders to biomacromolecules is a robust method to link their genotype and phenotype. A novel bacterial cell surface display technology has been developed to present cyclic peptides composed of synthetic and genetically encoded fragments in their backbones. The fragments were combined by protein trans-splicing and intramolecular oxime ligation. To this end, a split intein half and an unnatural amino acid were displayed with the genetically encoded part on the surface of Escherichia coli. Addition of the synthetic fragment equipped with the split intein partner and an aminooxy moiety, as well as the application of a pH-shift protocol, resulted in the onsurface formation of the semisynthetic cyclic peptide. This approach will serve for the generation of cyclic peptide libraries suitable for selection by fluorescence-activated cell sorting, and more generally enables chemical modification of proteins on the bacterial surface.

Abstract
Genetic code expansion through amber stop codon suppression provides a powerful tool for introducing non-proteinogenic functionalities into proteins for a broad range of applications. However, ribosomal incorporation of noncanonical amino acids (ncAAs) by means of engineered aminoacyl-tRNA synthetases (aaRSs) often proceeds with significantly reduced efficiency compared to sense codon translation. Here, we report the implementation of a versatile platform for the development of engineered aaRSs with enhanced efficiency in mediating ncAA incorporation by amber stop codon suppression. This system integrates a white/blue colony screen with a plate-based colorimetric assay, thereby combining high-throughput capabilities with reliable and quantitative measurement of aaRS-dependent ncAA incorporation efficiency. This two-tier functional screening system was successfully applied to obtain a pyrrolysyl-tRNA synthetase (PylRS) variant (CrtK-RS(4.1)) with significantly improved efficiency (+250-370 %) for mediating the incorporation of Nϵ -crotonyl-lysine and other lysine analogues of relevance for the study of protein post-translational modifications into a target protein. Interestingly, the beneficial mutations accumulated by CrtK-RS(4.1) were found to localize within the noncatalytic N-terminal domain of the enzyme and could be transferred to another PylRS variant, improving the ability of the variant to incorporate its corresponding ncAA substrate. This work introduces an efficient platform for the improvement of aaRSs that could be readily extended to other members of this enzyme family and/or other target ncAAs.

Abstract
Targeting protein surfaces and protein-protein interactions (PPIs) with small molecules is a frontier goal of chemical biology and provides attractive therapeutic opportunities in drug discovery. The molecular properties of protein surfaces, including their shallow features and lack of deep binding pockets, pose significant challenges, and as a result have proved difficult to target. Peptides are ideal candidates for this mission due to their ability to closely mimic many structural features of protein interfaces. However, their inherently low intracellular stability and permeability and high in vivo clearance have thus far limited their biological applications. One way to improve these properties is to constrain the secondary structure of linear peptides by cyclisation. Herein we review various classes of cyclic and macrocyclic peptides as chemical probes of protein surfaces and modulators of PPIs. The growing interest in this area and recent advances provide evidence of the potential of developing peptide-like molecules that specifically target these interactions.
