Peptide Applications

Today, we share a forward-looking perspective article led by the research team of Yi Cai from Sichuan Agricultural University, published in the authoritative plant science journal Molecular Plant. This article systematically elaborates on the immense potential of phytopeptides as next-generation biopesticides and biostimulants. Innovatively proposing a comprehensive innovation system encompassing "plant peptide identification, molecular design, bio-manufacturing, ecological assessment, synergistic innovation of pesticides and seeds, and field application," the paper integrates cutting-edge technologies such as artificial intelligence, nanotechnology, and synthetic biology. It provides a scientifically grounded and feasible systematic solution to address industrial bottlenecks, including the high production costs and poor field stability associated with peptide scale-up.

Today we share important research published in Advanced Materialsby the team of Guangyan Qing from the Dalian Institute of Chemical Physics, Chinese Academy of Sciences. Addressing the global challenge of specifically clearing blood endotoxin (LPS) in sepsis therapy, this study pioneeringly proposes a dual-affinity strategy. By screening high-affinity targeting peptides via phage display and constructing molecularly imprinted polymers with geometrically matched cavities through emulsion interfacial polymerization, followed by their conjugation, the work successfully creates an LPS adsorbent exhibiting high specificity, high adsorption capacity, and excellent biocompatibility, demonstrating outstanding therapeutic potential in septic animal models.

Today, we are sharing a research article led by the team of Kuan Zhang, published in Advanced Materials. This study proposes a modular design strategy that successfully develops a new generation of hydrogel bioadhesives by integrating genetically engineered supercharged polypeptides (SUP) with synthetic hydrogel networks. This strategy skillfully balances adhesion strength and cohesive strength, achieving rapid and effective hemostasis and wound healing in various complex physiological environments (such as the liver, beating heart, and acidic stomach). For the first time in such materials, it also enables gentle, triggerable benign detachment, providing a universal new paradigm for the development of biomedical adhesives.

Today, we share a research paper published in the Journal of Medicinal Chemistryby Henrik Fischer Munch's team. This study systematically details the rational design and optimization process of Petrelintide, a novel human amylin analogue. The research successfully overcame multiple drug development challenges associated with native amylin and its analogues, including physical instability (prone to fibrillation), chemical instability (susceptible to degradation and dimerization), and formulation incompatibility (requiring acidic pH for preparation). The final candidate molecule exhibits not only potent and long-acting pharmacological properties but, crucially, remains stable under neutral pH conditions and has been successfully co-formulated with the GLP-1 receptor agonist semaglutide, representing a breakthrough for next-generation combination therapies in weight management.

Today we are sharing a research article led by Zha Yuan's team, published in Analytical Chemistry. This study, through computationally biology-driven rational design, developed a novel Trop2-targeted peptide probe, [68Ga]Ga-NOTA-PEG2-WP8. It achieved, for the first time, non-invasive and dynamic Positron Emission Tomography (PET) imaging of Trop2 expression in triple-negative breast cancer (TNBC). It was also successfully applied for real-time monitoring of the treatment response to Trop2-targeted Antibody-Drug Conjugates (ADCs), providing a new molecular imaging tool for precision cancer diagnosis and therapy.

Today we share a study by Tobias Kronke et al., published in the Journal of Medicinal Chemistry. This research focuses on optimizing the structure of Nectin-4-targeting bicyclic peptides to develop 68Ga-labeled radioligands for tumor imaging. Through systematic structural modifications (such as bioisosteric replacement of methionine), the study not only improved the radiochemical purity and stability of the ligands but also validated their targeting efficacy for the first time in preclinical models and in a first-in-human application, providing a novel molecular tool for the precise diagnosis and treatment of Nectin-4-related cancers.

Today we are sharing a study led by Professor Oluf Pedersen from the University of Copenhagen, published in Nature Microbiology. This research, for the first time, discovered two novel peptides, RORDEP1 and RORDEP2, produced by the human gut commensal bacterium Ruminococcus torques(RT). These peptides are present in human circulation, show a negative correlation with obesity, and significantly improved glucose tolerance, increased bone density, and reduced fat accumulation in pre-clinical models. This provides new mechanistic insights and therapeutic potential for host metabolism regulation by microbially derived peptides.
