Oralpeptide Peptide inhibitors represent a significant and evolving class of therapeutic agents, offering unique advantages in their ability to modulate biological functions. These molecules, composed of short chains of amino acids, are increasingly recognized for their precision and efficacy in targeting specific biological pathways. Their intrinsic advantages as inhibitors or activators of protein-protein interactions (PPIs), compared to smaller molecules and antibodies, position them as critical tools in modern drug discovery and development.

The fundamental role of peptide inhibitors is to interfere with the biological function of target peptides or proteins. This can be achieved through various mechanisms, including blocking active sites, disrupting protein-protein binding, or altering protein conformation. The versatility of peptides allows for their application across a wide spectrum of diseases, from cancer to metabolic disorders and neurodegenerative conditions.Rational Design of Potent Peptide Inhibitors of the PD-1:PD ...

One of the most promising areas for peptide-based inhibitors is in the disruption of protein-protein interactions. These interactions are fundamental to numerous cellular processes, and their dysregulation is implicated in many diseases. For instance, research into peptide-based inhibitors of protein-protein interactions has highlighted strategies for generating effective peptide-based PPI inhibitors, often mediated by alpha-helices. The development of constrained peptides is a key emerging strategy in this field, enhancing their stability and binding affinity. This area is crucial for understanding recent progresses in drug discovery targeting PPIs.

In oncology, peptide inhibitors represent a promising therapeutic strategy for targeting signaling pathways involved in tumorigenesis. Peptide inhibitors are being explored as a means to break the cancer code, offering new avenues for treatment. For example, PD-1/PD-L1 inhibitors are known to promote tumor suppression by blocking the interaction of PD-L1 on tumor cells with its receptor, PD-1 on T cells, thereby reactivating the immune system against cancer.作者：J Fetse·2022·被引用次数：51—PD-1/PD-L1 inhibitors are known to promote tumor suppressionby blocking the interaction of PD-L1 on tumor cells with its receptor, PD-1 on T ... Furthermore, D-peptide antagonists of MDM2 have been validated as a class of p53 activators for the targeted molecular therapy of malignant neoplasms. The development of designing small protein-like molecules called peptides to specifically block receptors like HER2 is also an active area of research.Peptide-based inhibitors of protein–protein interactions

Beyond cancer, peptide inhibitors are showing significant potential in other therapeutic areas. In the context of neurodegenerative diseases, amyloid β-targeted inhibitory peptides are being evaluated for their ability to inhibit Aβ aggregation, a hallmark of Alzheimer's disease.作者：X Wang·2021·被引用次数：165—This review supplies a comprehensive overview ofrecent progresses in drug discovery targeting PPIsthrough peptides or peptidomimetics. For metabolic disorders, GLP-1 agonist drugs are a prime exampleGLP-1 Agonists. These medications, which mimic the actions of the endogenous incretin hormone, are approved to treat type 2 diabetes and obesity by balancing blood glucose levels. Understanding how to activate GLP-1 naturally, often through dietary strategies like eating protein and/or fat together with dietary fiber before carbohydrates, is also gaining attention.Enzyme Substrates and Inhibitors | PEPTIDE INSTITUTE ...

The design and synthesis of peptide inhibitors have seen remarkable advancements, driven by computational approaches. A computational approach for the design of target-specific peptides is revolutionizing the process, integrating sophisticated algorithms to create peptides with desired properties. This includes the development of deep generative models for peptide design, enabling the creation of novel and potent inhibitors. The field encompasses various forms of peptide-based inhibitors, including monocyclic peptides, bicyclic peptides, stapled peptides, and proteomimetic inhibitors.2025年7月1日—Eating protein and/or fat together with dietary fiberbefore carbohydrate is most effective at enhancing GLP-1 secretion. Potent bicyclic peptide inhibitors, for instance, are developed through structure-based stepwise optimization.

The advantages of peptide therapeutics extend to their ability to be modified for improved pharmacokinetic properties and targeted delivery. Peptide-small molecule drug hybrid inhibitors represent a novel approach that combines the binding strength of peptides with the favorable properties of small molecules. The exploration of oral peptide delivery systems is also a significant area of research, aiming to overcome the limitations of parenteral administrationPeptide-small Molecule Drug Hybrid Inhibitors.
