Cover for the Journal of Organic Chemistry: Advancements in Loop Cyclization Approaches for Enhanced Peptide Therapeutics for Targeting Protein-Protein Interactions
De novo protein design has advanced such that many peptide assemblies and protein structures can be generated predictably and quickly. The drive now is to bring functions to these structures, for example, small-molecule binding and catalysis. The formidable challenge of binding and orienting multiple small molecules to direct chemistry is particularly important for paving the way to new functionalities.
The COST Action SNOOPY brings together a network of experts and young researchers from diverse disciplines (chemistry, biology, biochemistry, materials science, nanotechnology, medicine, physics) to overcome existing barriers to predict and implement bioactive peptides’ ability to self-assemble into functional nanostructures, including those at the interface with membranes, potentially forming pores and channels.

This study focuses on mimicking peptide loops as a strategy for PPI inhibition, utilizing synthetic peptide loops for replicating critical binding regions. This work explores turn-inducing elements and highlights the importance of proline in promoting favorable conformations for lactamization, yielding high-purity cyclic peptides.
This review explores the potential of peptide-based biomaterials to enhance biomedical applications through self-assembly, biological responsiveness, and selective targeting. Peptides are presented as versatile agents for antimicrobial activity and drug delivery, with recent approaches incorporating antimicrobial peptides into self-assembling systems to improve effectiveness and reduce resistance. The review also covers peptide-based nanocarriers for cancer drug delivery, highlighting their improved stability, targeted delivery, and reduced side effects.
