Customization and Modification for Dendrimers

Dendrimers are capable of encapsulating drugs through electrostatic, van der Waals and H-bonding forces or chemical bonds due to their unique properties (e.g., well-defined size, spherical shape and internal void space). The dendrimer consists of three parts: the central core of the molecule, the inner layer of the branched unit, and the outer layer of the functional group. Common types include poly-lysine (PLL), poly-propyleneimine (PPI), poly-ethyleneimine (PEI), poly-aryl ethers, and poly-amidomethylamine ( PAMAM). However, the toxicity of dendrimers is the biggest obstacle limiting their clinical applications. CD Formulation offers a more mature technology to modify dendrimers to reduce toxicity and expand their applications.

Customization and Modification Services for Dendrimers

Our Services

CD Formulation focuses on the development of drug transport technologies and related solutions for pharmaceutical companies or research institutions to help them accelerate their drug development process. We provide solutions for dendrimers that focus on reducing their toxicity with two main strategies: customizing biocompatible or biodegradable materials; and surface modification of dendrimers.

Customized Biodegradable Dendrimers

CD Formulation offers customizable dendrimers including polyester dendrimers and polyacetal/polyketone dendrimers.

Surface Modification Services for Dendrimers

Customization and Modification Services for Dendrimers

CD Formulation typically uses polyethylene glycol (PEG) and its derivatives for surface modification. PEG and its derivatives can improve their water solubility, reduce enzymatic cleavage by metabolic enzymes and immune system in vivo, and prolong the retention time of drugs in vivo. Currently, we can successfully modify dendrimers, including bromination, amination, carboxymethylation, toluenesulfonation, methanesulfonation, aldolization, or methoxypolyethylene glycol (MPEG) chemistry. Dendrimers that are anionic or polyethylene glycolized and their derivatives are significantly less cytotoxic compared to cationic dendrimers with other surface groups. Our team of professionals will develop the right solution for you to help you accelerate drug development and drug efficacy transport.

The Advantages of Dendrimers

  • Stable single-molecule structure to avoid structural collapse in physiological environments.
  • A defined number of surface functional groups that can be modified with a variety of targeting ligands, such as targeted peptides for targeted delivery of nanomedicines.
  • The internal cavity can contain hydrophobic small molecule drugs.
  • Easy to penetrate cell membrane and enhance the uptake efficiency of small molecule drugs.
  • As a drug carrier, it can prolong the retention time in the blood, control the release rate in the body and protect the drug from environmental damage, with good As a drug carrier, it can prolong the retention time in the blood, control the rate of drug release in the body, protect the drug from environmental damage, and have good slow release and targeting.
