At their core, peptide polymers, also referred to as polypeptides, are macromolecules formed by the repetitive linkage of amino acids.Synthesis, Structure, and Function of Peptide–Polymer ... When these peptide sequences are combined with synthetic or natural polymers, they create peptide-polymer conjugates or hybrids.作者：J Martin·2021·被引用次数：34—Peptides can be associated to polymerscombining the properties of various polymer backbones with those of bioactive peptide sequences. This conjugation aims to enhance the desirable attributes of both components作者：H Zhao·2025·被引用次数：6—The key role of polymers inimproving the antimicrobial activity, stability, cytotoxicity, and bioavailability of peptidesis emphasized based on the reported .... For instance, associating peptides with polymers can improve their solubility, stability, and bioavailability, overcoming some of the inherent limitations of peptides alone. Conversely, peptides can impart specific biological recognition or activity to the polymer backbone, leading to materials with advanced functionalities.
The synthesis of peptide polymers involves various chemical and biological approaches. Techniques such as RAFT polymerization are frequently employed for the controlled synthesis of peptide-polymer conjugates, allowing for precise control over molecular weight, architecture, and the number of peptide units. Other methods focus on directly polymerizing peptide monomers or conjugating pre-formed peptides to polymer chains.
The design of these materials is critical for achieving specific functionalities. Researchers can tune the properties of peptide polymers by carefully selecting the amino acid sequence of the peptide component and the chemical structure of the polymer backbone.AlphaFold Serveris a web-service that can generate highly accurate biomolecular structure predictions containing proteins, DNA, RNA, ligands, ions, and also ... This allows for the creation of materials with designed properties, such as self-assembly into specific nanostructures, responsiveness to environmental stimuli like pH or temperature, and targeted biological interactions. For example, self-assembling peptide (SAP)–polymer hybrids are a class of materials engineered to form complex nano-objects through the combined forces of peptide self-assembly and polymer interactions.Peptide-Based Polymer Therapeutics
The unique properties of peptide polymers have led to their exploration in a wide array of applications:
* Therapeutics and Drug Delivery: Peptide-polymer conjugates are showing significant promise as polypeptide-based constructs for drug delivery systems. Their ability to encapsulate or conjugate therapeutic agents, coupled with their potential for targeted delivery and controlled release, makes them valuable in treating various diseases. They are also used in wound dressing, bone tissue repair, and as antibacterial coatings for medical devices.
* Biomaterials: Polypeptides themselves represent a class of molecules uniquely suited for biomaterial applications due to their biocompatibility and biodegradability. When integrated into polymers, they can form advanced biomaterials for tissue engineering and regenerative medicine.
* Antimicrobial Agents: Antimicrobial peptide-polymers are being developed to combat bacterial infections. By combining the inherent antimicrobial activity of peptides with the favorable properties of polymers, these materials can offer improved efficacy, stability, and reduced cytotoxicity compared to traditional antibiotics.作者：JY Shu·2013·被引用次数：283—Peptide/protein-polymer conjugatesmake up a new class of soft matter comprising natural and synthetic building blocks.
