Protein based protac The field of targeted protein degradation has witnessed a paradigm shift with the advent of peptide PROTACs. These innovative molecules represent a significant advancement in drug development, offering a novel strategy for addressing previously undruggable or drug-resistant proteins. Peptide PROTACs leverage the body's natural protein degradation machinery, the ubiquitin-proteasome system (UPS), to selectively eliminate disease-causing proteins.

At its core, a PROTAC (proteolysis-targeting chimera) is a heterobifunctional molecule.Non-small molecule PROTACs (NSM-PROTACs): Protein ... It comprises three key components: a target-binding moiety, a linker, and an E3 ligase-binding moiety. This unique structure allows the PROTAC to simultaneously bind to both the target protein of interest (POI) and an E3 ubiquitin ligase. This proximity then tags the POI with ubiquitin, marking it for degradation by the proteasome. The peptide PROTAC modality, specifically, utilizes peptides as one or more of these components, offering distinct advantages.

The early development of PROTACs involved peptide PROTAC as the initial form. While early peptide-based PROTACs faced challenges with their pharmacokinetic (DMPK) profiles, subsequent research has led to significant improvements.Peptide-based PROTAC degrader of FOXM1 suppresses ... For instance, the development of stapled peptide-based PROTACs has enhanced their stability and cell permeability. These advancements have paved the way for peptide-based PROTACs to become a feasible proposition for targeting proteins that are not amenable to traditional small molecule inhibition.

The advantages offered by peptide PROTACs over traditional peptide drugs are substantial. Their auxiliary action mechanism and synergetic therapeutic effect contribute to superior outcomes. Researchers have demonstrated that peptide PROTACs can effectively degrade specific proteins, leading to therapeutic benefits. For example, BPD is a peptide-based PROTAC that has shown efficacy in degrading BRCA2, selectively accumulating in tumor cells and reducing homologous recombination. Similarly, Nano-PROTACs have significantly inhibit tumor growth in preclinical models, exhibiting dose-dependent antitumor effects.
