Abstract

Disclosed herein are pharmaceutical compositions comprising fencamfamine or fencamfamine related prodrug derivatives for targeted therapeutic applications and methods of synthesizing the compositions.

Claims (15)

1. A prodrug composition comprising at least one conjugate of N-ethyl-3-phenylbicyclo[2.2.1]heptan-2-amine or any of its stereoisomers, wherein the conjugate is a compound selected from the group consisting of:

2. The prodrug composition of claim 1 , wherein the compound has the structure of:

3. The prodrug composition of claim 1 , wherein the compound has the structure of:

4. The prodrug composition of claim 1 , wherein the compound has the structure of:

5. The prodrug composition of claim 1 , wherein the compound has the structure of:

6. The prodrug composition of claim 1 , wherein the compound has the structure of:

7. The prodrug composition of claim 1 , wherein the compound has the structure of:

8. The prodrug composition of claim 1 , wherein the compound has the structure of:

9. The prodrug composition of claim 1 , wherein the compound has the structure of:

10. The prodrug composition comprising the compound of claim 1 , wherein the prodrug composition has an increased plasma or blood concentration of the released N-ethyl-3-phenylbicyclo[2.2.1]heptan-2-amine when administered orally as compared to when it is administered intravenously and when the unconjugated drug is administered in equimolar amounts.

11. The prodrug composition comprising the compound of claim 1 , wherein the prodrug composition is in the form comprising a tablet, a capsule, elixir, emulsion solution, suspension solution, or syrup.

12. A method for treating cancer-related fatigue, the method comprising administering an effective amount of the compound of claim 1 to a subject in need thereof.

13. The method of claim 12 , wherein the prodrug composition provides reduced ability to abuse the drug composition when compared to the unconjugated N-ethyl-3-phenylbicyclo[2.2.1]heptan-2-amine.

14. The method of claim 12 , wherein the subject is mammalian.

15. A method for treating Alzheimer's disease, Parkinson's disease, major depressive disorder, or attention deficit hyperactivity disorder, the method comprising administering an effective amount of the compound of claim 1 to a subject in need thereof.
