PAMAM Dendrimer Synthesis Service

PAMAM Dendrimer Synthesis Service

Polyamido-amines (PAMAM) is the first dendrimer to be synthesized and commercialized and is the most well-studied and characterized class of dendrimers. As the world's leading provider of custom services, CD BioSciences has the advanced equipment and experienced scientists to offer you PAMAM synthesis services.


Overview of PAMAM Dendrimers

Poly(amidoamine), or PAMAM, is the first dendrimer to be synthesized and commercialized and is the most well-studied and characterized class of dendrimers consisting of repeating branched subunits of amide and amine functionality, which are three-dimensional molecules with repeating branched chains. The core of PAMAM consists of linear chain molecules containing primary amines, most commonly ethylenediamine (EDA, four core multiplicity), ammonia (three core multiplicity) or cystamine (four core multiplicity).

Like other dendritic polymers, PAMAM has an overall sphere-like shape and is typified by an internal molecular structure composed of tree-like branching, with each outward "layer" or generation containing exponentially more branching points. The branched structure of PAMAM allows for low polydispersity and a high level of structural control during synthesis and generates many surface sites relative to the overall molecular volume, thus distinguishing it from other dendritic or conventional polymers. In addition, it is possible that PAMAM exhibits greater biocompatibility due to the combination of surface amine and internal amide bonds.

Structure of PAMAM Dendrimers

As a class of nanoscale compounds with well-defined monodisperse and homogeneous molecular structures, dendrimers are considered as the fourth and newest class of polymers. Moreover, dendrimers differ from classical oligomers/polymers due to their symmetry, high molecularity, and maximum terminal functional density. Dendrimers consist of three main components.

  • The core, which serves as the "germinating seed" and is the anchor point for the growth of the dendrimers.
  • The inner layers and internal branches that make up the generations.
  • An outer layer, the terminal functionalized branch.

Dendrimer ends can be modified by small molecules (including ions, drugs, and biomolecules) that alter the physicochemical, reactive, kinetic, and biological properties of the dendrimer ground.

Synthesis of PAMAM Dendrimers

There are generally many methods for the synthesis of dendrimers, of which convergent and divergent methods are the most common ones. In addition, many new methods have been developed, such as click chemistry, hypercores, branching monomers and double exponential, etc., which can also be used to synthesize dendrimers by a combined convergent-divergent approach.
