Abstract

The present disclosure generally relates to nanoparticles comprising an endo-lysosomal escape agent, a nucleic acid, and a polymer. Other aspects include methods of making and using such nanoparticles.

Claims (11)

1. A pharmaceutically acceptable nanoparticle comprising:

a nucleic acid and a hydrophobic counter ion agent and about 50 to about 99.75 weight percent of a diblock poly(lactic) acid-poly(ethylene)glycol copolymer or a diblock poly(lactic acid-co-glycolic acid)-poly(ethylene)glycol copolymer, wherein the counter ion is selected from the group consisting of chlorpromazine, fluoxetine, promethazine, cetylpyridinium, hydrabamine, ethyl lauroyl arginate, amitriptyline, amiodarone, and doxepin.

2. The pharmaceutically acceptable nanoparticle of claim 1 , wherein the counter ion is chlorpromazine.

3. The pharmaceutically acceptable nanoparticle of claim 1 , wherein the counter ion is fluoxetine.

4. The pharmaceutically acceptable nanoparticle of claim 1 , wherein the counter ion is promethazine.

5. The pharmaceutically acceptable nanoparticle of claim 1 , wherein the counter ion is cetylpyridinium.

6. The pharmaceutically acceptable nanoparticle of claim 1 , wherein the counter ion is hydrabamine.

7. The pharmaceutically acceptable nanoparticle of claim 1 , wherein the counter ion is ethyl lauroyl arginate.

8. The pharmaceutically acceptable nanoparticle of claim 1 , wherein the counter ion is amitriptyline.

9. The pharmaceutically acceptable nanoparticle of claim 1 , wherein the counter ion is amiodarone.

10. The pharmaceutically acceptable nanoparticle of claim 1 , wherein the counter ion is doxepin.
