Abstract

Abstractl‐carnosine is a bipeptide with varieties of biomedical benefits, but rarely reported as a component in structurally defined polymers due to the unavailability of isolatable monomers. In this report, a simple method to synthesize a carnosine‐derived methacrylamide in three steps is established and a neutral polymer with a narrow molecular weight distribution (Mn 7.6 kDa, Ð 1.2) and high structural regularity is prepared via free radical polymerization, and a carnosine‐pendent cationic homopolymer is finally achieved after trifluoroacetic acid‐mediated deprotection without a concern of impurities such as metals. The antioxidative activity, cytotoxicity, DNA‐binding capability, and gene delivery performance of the cationic polymer are also studied.
