Dendrimer-Peptides Conjugation Service

Dendrimer binding to a peptide as a ligand enables targeted delivery of drugs. CD BioSciences has advanced facilities and experienced scientists to provide high quality peptides binding to dendrimers.

Ligands in Drug Delivery Systems

Targeted drug delivery systems are highly efficient and promising intelligent systems that are non-immunogenic, biocompatible, deliver drugs to specific tissues or organs and release specific amounts of drugs over a longer period, and are also suitable for both in vitro and in vivo drug delivery. Targeted drug delivery systems not only minimize drug damage to normal tissues, but also improve the bioavailability of drugs. In the preparation of targeted drug delivery systems, the surface properties and receptors of the target cells, the nature of the drug carriers and the appropriate ligands need to be considered. Target delivery can be achieved by passive or active strategies. Passive strategy involves loading the drug into the nanocarrier to achieve targeted delivery of the drug by enhancing drug permeability and retention (EPR) phenomenon. Passive drug delivery strategies involve coupling the drug-delivering nanocarrier to a specific ligand that can bind to a specific receptor on the surface of the diseased cell. Since many natural ligands can bind to a wide range of cell surface specific receptors, ligands are important in targeted drug delivery systems.

Dendrimer-Peptides Conjugation

Dendrimers are nanoscale, three-dimensional macromolecules with well-defined globular structures that hold promise for various aspects of gene and drug delivery due to their multivalent and host-guest entrapment properties. However, like other nanomaterials, dendrimers still have some drawbacks that can reduce the effectiveness of drug therapy, such as rapid clearance of dendrimers by the reticuloendothelial system, cytotoxicity from the interaction of amine terminated group with cell membrane and low transfection efficiency and lack of controlled release behavior, among others. To address these issues, surface functionalization of dendrimers can be carried out. Peptides are versatile and easy to prepare as ligands. When dendrimers are modified by peptides, i.e., linkage occurs, better targeting of drugs can be achieved. For example, when dendrimers bind to FSH they can selectively target FSHR for ovarian cancer treatment. When dendrimers bind to T7, they can easily enter cells with the help of transferrin, enhancing drug targeting to tumors while improving transfection efficiency. In addition, dendrimers can also bind to a variety of peptides such as LF, RGD and Pep-1.
