Peptide-drugconjugatesreview The field of targeted drug delivery is rapidly evolving, with antibody-peptide conjugates emerging as a significant innovation. These sophisticated hybrid molecules consisting of an antibody linked to a peptide are poised to revolutionize therapeutic strategies, particularly in the realm of oncology and metabolic diseases.2023年10月3日—Antibody–drug conjugates are powerful tools for combatting a wide array of cancers. Drug conjugation to a therapeutic antibody often alters ... Building upon the success of antibody-drug conjugates (ADCs), antibody-peptide conjugates offer unique advantages, including enhanced specificity, improved pharmacokinetic profiles, and potentially reduced off-target toxicities.

The fundamental principle behind antibody-peptide conjugates lies in harnessing the exquisite targeting capabilities of antibodies. Antibodies, specifically monoclonal antibodies, can recognize and bind to unique antigens expressed on the surface of diseased cells, such as cancer cells.作者：A Petruzzella·2024·被引用次数：22—Ourantibody–peptide inhibitor conjugatesspecifically blocked the activity of cathepsins in different cancer cells, as well as osteoclasts, and showed ... By chemically or biologically linking a peptide to this antibody, researchers can create a delivery system that precisely directs therapeutic payloads to the intended sites of action. This conjugation process, which uses chemical and biological methods to create covalent connections between specific peptide segments and antibody structures, is a critical aspect of their development.

One of the key advantages of antibody-peptide conjugates over traditional treatments and even some earlier forms of targeted therapies is their ability to overcome limitations associated with smaller molecules or naked peptides. For instance, Peptide-drug conjugates (PDCs), which share similarities in their modular design, are often highlighted for their smaller size for deeper tissue penetration. While ADCs are recognized as powerful biopharmaceuticals that deliver highly toxic drugs or payloads, the incorporation of peptides can offer distinct benefits. For example, specific peptide conjugation to a therapeutic antibody leads to enhanced therapeutic potency and thermal stability due to reduced Fc dynamics, as demonstrated in research by Kiyoshi and colleagues. Furthermore, the development of antibody-peptide inhibitor conjugates (APICs), which conjugates non-natural peptide inhibitors (NNPIs) with antibodies, represents a sophisticated approach to directly blocking the activity of specific cellular targets, such as cathepsins in cancer cells.

The therapeutic potential of antibody-peptide conjugates is vast and continues to be explored across various disease areas. In oncology, these conjugates can be designed to deliver cytotoxic agents directly to tumor cells, thereby minimizing damage to healthy tissues.Site-Specific Chemical Conjugation of Antibodies by Using ... This targeted approach is crucial for improving treatment efficacy and reducing the debilitating side effects often associated with conventional chemotherapy. Research into antibody-peptide epitope conjugates (APEC), for instance, aims to redirect T-cell viral immunity against tumor cells, showcasing a novel immunotherapeutic strategySpecific peptide conjugation to a therapeutic antibody ....

Beyond cancer, antibody-peptide conjugates are showing promise in the treatment of metabolic disorders. A notable example is the antibody-peptide conjugate known as MariTideAntibody-Peptide Conjugates Generation Service. Studies have shown that MariTide can induce significant weight loss in individuals with obesity and type 2 diabetes, outperforming placeboPeptide–Drug Conjugates as Next-Generation Therapeutics. This therapeutic effect is attributed to the conjugate's ability to leverage the longer half-life of the antibody-peptide conjugate compared to standalone peptides or small molecule drugs, as highlighted in recent progress reports.作者：K Jadhav·2025·被引用次数：19—PDCs offer several advantages over antibody–drug conjugates (ADCs), includingsmaller size for deeper tissue penetration, faster clearance reducing off-target ...
