ABSTRACT:
A cyclic carbonate monomer, including:whereinR1, R2, and R3are independently selected from the group consisting of H, linear or branched, substituted or unsubstituted alkyl;R10is a connecting group selected from the group consisting of linear or branched, substituted or unsubstituted alkyl, heteroalkyl, cycloalkyl, heterocyclic, aryl and heteroaryl;R4is an optional bridging group selected from the group consisting of linear or branched, substituted or unsubstituted alkyl, heteroalkyl, cycloalkyl, heterocyclic, aryl and heteroaryl;Z is selected from the group consisting of O, NH, NR, and S;G is a guanidine group; andP is a protecting group.The cylic carbonate monomer can be reacted with an initiator including a drug, drug candidate, probe or other molecule of interest to form an oligomer with the molecule of interest attached to one end of a carbonate backbone and guanidine groups attached to the carbonate backbone.
