Emerging strategies include:
* Constrained Peptides: These peptides have modifications that lock them into specific three-dimensional structures, often mimicking natural protein interfaces more effectively and enhancing their inhibitory power.
* Peptidomimetics: These are molecules that mimic the structure and function of peptides but may have improved pharmacokinetic properties, such as increased stability against enzymatic degradationTherapeutic peptides: current applications and future directions.
* Covalent Peptide Inhibitors: Some peptide inhibitors are designed to form a permanent covalent bond with their target protein, leading to irreversible inhibition.
* Molecular Glues: Certain cyclic peptides can act as molecular glues, bringing together different protein subunits and thereby inhibiting their normal function, as seen in the inhibition of G protein signaling.
