  A family of cationic lipids was synthesized via direct amide coupling of spermine to the C-24 position of cholic acid analogs. Four monosubstituted spermines and a bis-substituted spermine were evaluated as plasmid transfection reagents, as bacteriostatic agents, and as bactericidal agents. The incorporation of a double bond in the sterol moiety enhanced transfection efficiency significantly and produced two compounds with little cytotoxicity and transfection potency comparable to Lipofectamine2000 (TM). Inclusion of the double bond had no effect on the general trend of increasing bactericidal activity with increasing sterol hydrophobicity. Co-formulation of the most hydrophilic of the compounds with its bis-substituted analogue led to enhancement in transfection activity. The bis-substituted compound, when tested alone, emerged as the most bacteriostatic compound in the family with minimum inhibitory concentrations (MIC) of 4 mu M against Bacillus subtilis and 16 mu M against Escherichia coli and therapeutic indexes (minimum hemolytic concentration/minimum inhibitory concentration) of 61 and 15, respectively. Cationic lipids can be optimized for both gene delivery and antibacterial applications by similar modi. cations. (C) 2009 Elsevier Ltd. All rights reserved.
