Abstract
Antimicrobial, non-hemolytic cationic polyamines were prepared by treating partially N-acylated polyethylenimines and/or partially oxidized polyethylenimines with a protic acid. The cationic polyamines can have a linear or branched polyethylenimine backbone structure. Preferably, the cationic polyamines comprise pendant urea groups, which can be introduced via a cyclic carbonate comprising a pendant urea group. The cationic polyamines can be active against a tuberculosisat low concentration. The cationic polyamines are also effective against Gram-negativeand, Gram-positive, and fungusin solution and in the form of a film.
