Recent work carried out by Wangyu, Matteo and Thiru has been selected as a Very Important Publication (VIP) at ChemSusChem. The key achievement of this work is the synthesis of polycarbonate-drug conjugates with a controlled amount of drug. These newly developed polymers can be tailored in terms of drug content, and additional functionality to change the macromolecular (thermal, physical) properties. The protocol is amenable to a wide range of carboxylate-functionalized drugs. This is an example of a nice piece of an “in-group” collaboration!
