The merck p53 stapled peptide patent landscape highlights a sophisticated approach to drug development, where chemical modifications to natural peptides enhance their stability and therapeutic efficacyIDP-410: a Novel Therapeutic Peptide that Alters N-MYC ....
At the core of this research are stapled peptides. These modified peptides are engineered with an artificial cross-link, often referred to as a "staple," that spans across an alpha-helical structure. This structural reinforcement significantly improves the peptide's stability in biological environments, preventing its degradation and prolonging its therapeutic action. This innovation is critical because natural peptides, while potent, are often susceptible to rapid breakdown by cellular proteases.作者:MR Schnorenberg·2023·被引用次数:12—In this work, we hypothesized thatp53reactivation using.

A key target for these stapled peptides is the disruption of interactions between p53 and its negative regulators, specifically MDM2 and MDMX. These oncoproteins bind to p53, marking it for degradation and thus neutralizing its tumor-suppressing functions. Stapled p53 peptides are designed to bind to MDM2 and MDMX, displacing p53 and allowing it to become active again.作者:DC Morgan·2025—This diyne-girder-stapled peptidedemonstrated enhanced helicity and nanomolar binding affinity for MDM2, as assessed by fluorescence. This activation can then trigger apoptosis (programmed cell death) in cancer cells or halt their proliferation.作者:M Payton·2017·被引用次数:9—ALRN-6924 is a cell-penetrating stapled alpha-helical peptidedesigned to equipotently disrupt the interaction between the p53 tumor suppressor protein and ... The non-membrane disruptive p53 activating stapled peptides represent a significant advancement, suggesting improved cellular penetration and targeted delivery without compromising cell integrity.
Several patented technologies and research efforts underpin Merck's involvement in this field. For instance, patents like US9527896B2 describe "Stabilized p53 peptides and uses thereof," detailing how these modified peptides interfere with the MDM2 binding, thereby inhibiting p53 destruction. Furthermore, collaborations and patent filings, such as the mention of EP3256484A1 pending, indicate ongoing research and development, potentially involving specific compounds like PM2.
The development of ALRN-6924, a cell-penetrating stapled alpha-helical peptide, exemplifies the clinical progression of this technology. Described as the first-in-class clinical stage stapled peptide, ALRN-6924 is designed to equipotently disrupt the interaction between the p53 tumor suppressor protein and its regulators.Development of an albumin-binding ligand for prolonging ... Clinical trials, including Phase I and Phase II studies, have investigated ALRN-6924 for its efficacy in patients with solid tumors and lymphomas, assessing its potential to restore normal p53-mediated apoptosis activity. This drug also functions as a dual inhibitor of MDMX and MDM2, underscoring the therapeutic strategy of targeting multiple regulatory proteins.
