Polyester bis-MPA dendron 8 NHBoc, 1 thiol (core) , generation 3

Polymer architecture: Dendron; End Group Functionality: Boc-protected amine; Boc : tert-Butyloxycarbonyl; Bis-MPA : 2,2-Bis(hydroxymethyl)propionic acid.

Bis-MPA (or 2,2-Bis(methylol)propionic acid) is an aliphatic, pro-chiral molecule comprised of two hydroxyls and one carboxylic group that has been used in the synthesis of many different types of polymers. Dendrons synthesized from bis-MPA are biodegradable and have low cytotoxicity, making them well suited for use in biological research applications. These materials have been used in many applications such as signal amplification in bioassays and in drug delivery applications. After Boc deprotection, amine-functionalized dendrons can be readily used in EDC or DCC coupling reactions with carbonyl-containing compounds to yield highly functionalized materials for a variety of biomedical applications. Additionally, the thiol-core can be readily conjugated via a thiol-ene click reaction, Michael addition reactions, or disulfide exchange.
