A third generation dendrimer based on glycerol and lactic acid was first synthesized through iterative esterification and deprotection reactions. Though this dendritic structure was prone to self-degradation, it led to the development of a dendrimer composed of succinic acid instead of lactic acid.

520 # $a A third generation dendrimer based on glycerol and lactic acid was first synthesized through iterative esterification and deprotection reactions. Though this dendritic structure was prone to self-degradation, it led to the development of a dendrimer composed of succinic acid instead of lactic acid.
520 # $a Dendrimers are monodisperse macromolecules made of branched repeat units originating from a central core. These highly branched polymers have been utilized in a variety of medical applications, but the dendritic structures have not been specifically designed for these purposes. To address this concern, novel dendrimers composed of glycerol and either lactic, succinic, or adipic acid were developed for a variety of clinically relevant applications. These "biodendrimers" are composed entirely of building blocks known to be biocompatible or degradable in vivo to natural metabolites.
520 # $a The PGLSA framework was also modified with a malic or adipic acid monomer to further tailor the dendritic architecture for specific applications. The adipic acid monomer lengthens the dendritic structure and may provide a larger more hydrophobic interior for the encapsulation of hydrophobic drugs. The synthesis of the layered-block dendrimers also demonstrated the reliance of the dendrimer's properties on the outer generation of monomer units.
520 # $a The poly(glycerol succinic acid) (PGLSA) dendrimers were prepared using a high yield divergent approach. Using a similar reaction sequence, up to five generations of the PGLSA dendrimer were synthesized and derivatized according to the desired application. Alkene terminated dendrimers were investigated as scaffolds for tissue engineering and as light activated sealants for corneal lacerations. Lysine terminated dendrimers were investigated as gene transfection agents. In addition, hydroxy- and carboxy-terminated dendrimers were used to encapsulate hydrophobic compounds.
520 # $a To increase the water solubility of the dendrimers with hydrophobic peripheral functionalities, PGLSA dendrimers with a poly(ethylene glycol) core were synthesized. The methacrylated first generation of this dendrimer was used to seal 4 mm linear lacerations during in vitro studies involving human enucleated eyes and in vivo studies using the white leghorn chicken eye. These studies suggested that the use of a biodendrimer adhesive was a viable alternative clinical procedure to conventional sutures.
