wherein m is any integer from 1 to 3 and

Y − is a pharmaceutically acceptable anion.

2. The composition according to claim 1 , wherein R 1 and R 2 are each and independently selected from the group comprising lauryl, myristyl, palmityl and oleyl.

3. The composition according to claim 1 , wherein R 1 is lauryl and R 2 is myristyl; or R 1 is palmityl and R 2 is oleyl.

4. The composition according to claim 1 , wherein m is 1 or 2.

5. The composition according to claim 1 , wherein Y − is selected from the group consisting of halogenids, acetate, and trifluoroacetate.

6. The composition according to claim 1 , wherein the compound is selected from the group consisting of:

7. The composition according to claim 1 , wherein the composition further comprises a pharmaceutically active component selected from the group consisting of peptides, proteins, oligonucleotides, polynucleotides, and nucleic acids.

8. The composition according to claim 7 , further comprising at least one helper lipid component selected from the group consisting of phospholipids and steroids.

9. The composition according to claim 8 , wherein the helper lipid component is selected from the group consisting of 1,2-diphytanoyl-sn-glycero-3-phosphoethanolamine and 1,2-dioleyl-sn-glycero-3-phosphoethanolamine.
