Abstract
The present invention provides inventive conjugated polyethyleneimine (PEI) polymers and conjugated aza-macrocycles (collectively referred to herein as “conjugated lipomers” or “lipomers”) containing one or more groups of the formula (iii): wherein R3 and R4 are as defined herein. Also provided are compositions comprising the inventive conjugated lipomers, and methods of preparation and use.
