Abstract

Two sets of novel multiheaded cationic amphiphiles bearing one, two, and three trimethylammonium headgroups (T1, T2, and T3) and pyridinium headgroups (P1, P2, and P3), have been synthesized and tested for antimicrobial activities against both Gram-positive and Gram-negative bacteria. The multicationic headgroups in these amphiphiles were attached covalently via scissile ester-type linkages. The results were compared with those ...
