Peptide-drug conjugates The field of medicine is continually seeking more effective and targeted ways to administer therapeutic agents. Among the most promising advancements is the development of peptide drug delivery systems. These sophisticated platforms are revolutionizing how peptide and protein-based drugs are utilized, offering enhanced efficacy, reduced side effects, and novel therapeutic possibilities. With peptides themselves having a shorter half-life in the blood circulatory system compared to larger biomolecules, the need for robust drug delivery systems is paramount to achieving optimal therapeutic outcomes.

Peptide-based drug delivery systems are engineered to encapsulate or conjugate with therapeutic molecules, ensuring their effective transport and release within the body. This approach addresses a critical challenge in peptide therapeutics: poor oral bioavailability and rapid degradation. By employing various strategies, these systems aim to improve the stability, bioavailability, and targeted delivery of peptide drugs. Research by Guo et al. (2024) highlights how peptide-based DDSs are frequently employed to deliver therapeutic substances such as anti-cancer drugs and nucleic acid-based drugs, effectively slowing their degradation and enhancing their therapeutic impact.Peptide-Based Drug Delivery Systems - CD Bioparticles

One of the significant advantages of peptide-based drug delivery platforms lies in their inherent biocompatibility and low immunogenicity. Unlike some synthetic materials, peptides are naturally occurring molecules, often eliciting minimal immune responses. This makes them ideal carriers for sensitive therapeutic agents.Peptide-Based Drug-Delivery Systems in Biotechnological ... Furthermore, peptide-based delivery systems offer various advantages including a high safety profile and controlled dosage of administration, as noted by Du et al.作者：W Xiao·2025·被引用次数：186—This paper provides an overview of the present market and clinical trial progress ofpeptide-based therapeutics, delivery platforms, and vaccines. (2025). This controlled release mechanism is crucial for maintaining therapeutic drug levels over extended periods, particularly for chronic conditions where regulatory proteins and peptides are indicated for long-term therapy.Advances in peptide-based drug delivery systems

The diversity of peptide drug delivery approaches is vast and continually expandingPeptidedrug delivery is the use ofpeptidesas a drug carrier or as a targeting agent as part of adrug delivery systemto transport a drug, where it can be .... Self-assembled peptide nanomaterials for drug delivery represent a significant area of innovation. These materials can spontaneously form complex nanostructures in solution, providing a versatile scaffold for drug encapsulation.Peptide-Based Drug Delivery Systems - CD Bioparticles Another prominent strategy involves peptide-drug conjugates, where the peptide is chemically linked to the therapeutic agent. This can enhance targeting to specific cells or tissues expressing receptors that bind to the conjugated peptide. For instance, GE11 peptide-mediated drug delivery systems, including liposomes and polymeric micelles, have been developed for disease diagnosis and drug delivery (Liu et al., 2021).

The application of peptide-based drug delivery systems extends across a broad spectrum of diseases. For delivering anti-cancer drugs, these systems can be designed to specifically target tumor cells, minimizing damage to healthy tissues. Similarly, for delivering nucleic acid-based drugs, such as mRNA, peptides have demonstrated great potential as promising carrier candidates due to their high cell membrane permeability and good biodegradability (Liang et alPeptide-Based Drug Delivery Systems., 2025).作者：VK Nikam·2022·被引用次数：4—Mostpharmaceuticalproteins andpeptidesare absorbed by IM,.

Beyond targeted delivery, peptide-based drug delivery platforms can also be designed to respond to specific environmental cues within the body.In other cases regulatory proteins andpeptidesare indicated for chronic therapy and here they will need to be administered by an appropriatedelivery system. This "smart" drug delivery concept allows for the release of the therapeutic agent only when and where it is needed, further optimizing treatment efficacy and reducing systemic exposure. Examples include systems that release drugs in response to changes in pH, temperature, or the presence of specific enzymes.

The clinical progress of peptide-based therapeutics, delivery platforms, and vaccines is a testament to the growing importance of this fieldTypes of APIs (Small Molecules, Peptides, Biologics) - Bio-Synth. Xiao et al. (2025) provide an overview of the present market and clinical trial progress, indicating a robust pipeline of peptide-based innovations. While parenteral routes such as intravenous, intramuscular (IM), and subcutaneous administration are common for many pharmaceutical proteins and peptides, the development of alternative delivery methods, including hydrogels and transdermal drug delivery systems, is also progressing, aiming to improve patient compliance and convenience.作者：D Tesauro·2019·被引用次数：251—In this review, we focus on the design and the characterization ofdrug delivery systemsusingpeptide-based carriers.

In summary, peptide drug delivery is a dynamic and rapidly evolving area of pharmaceutical research. By leveraging the unique properties of peptides, scientists are developing innovative drug delivery systems that promise to enhance the therapeutic potential of peptide-based medications, offering a brighter future for patients undergoing treatment for a wide range of conditions. The ongoing research and development in this sector underscore the commitment to find an optimal way to deliver drugs to target tissues with unprecedented precision and efficacy.
