Claims (25)

1. A compound of Formula IA:

or esters, or salts thereof, wherein:

Z is O;

R 1 is alkyl and R 2 is hydrogen or alkyl, or R 1 and R 2 form a carbocyclic ring;

R 3 is hydrogen, a sodium ion, or a quaternary ammonium ion; and

R 3 ′ is sodium or a quaternary ammonium.

2. The compound of claim 1 , wherein R 1 is methyl.

3. The compound of claim 1 , wherein R 2 is hydrogen.

4. The compound of claim 1 , wherein R 1 and R 2 are methyl.

5. The compound of claim 1 , wherein R 1 and R 2 form a carbocyclic ring and wherein the carbocyclic ring is a saturated carbocyclic ring or an unsaturated carbocyclic ring.

6. The compound of claim 5 , wherein the carbocyclic ring is a saturated carbocylic ring selected from the group consisting of cyclopropyl, cyclobutyl, cyclopentyl, and cyclohexyl.

7. The compound of claim 5 , wherein the carbocyclic ring is an unsaturated carbocyclic ring selected from the group consisting of cyclopentenyl and cyclohexenyl.

8. The compound of claim 1 , wherein R 3 is a sodium ion.

9. The compound of claim 1 , wherein R 3 is a quaternary ammonium ion.

10. The compound of claim 1 , wherein R 3 is hydrogen and R 3′ is a sodium ion.

11. The compound of claim 1 , wherein R 3 is hydrogen and R 3′ is a quaternary ammonium ion.

12. The compound of claim 1 , wherein R 3 and R 3′ are sodium ions.

13. The compound of claim 1 , wherein R 3 and R 3′ are quaternary ammonium ions.

14. A pharmaceutical composition comprising a compound of claim 1 and a pharmaceutically acceptable excipient.

15. The pharmaceutical composition of claim 14 , further comprising a second active therapeutic agent.

16. A method of reducing the symptoms or delaying the progression of stroke or traumatic brain injury comprising administering an effective amount of a pharmaceutical composition of claim 14 to a subject in need thereof.

17. The method of claim 16 , wherein the pharmaceutical composition is administered to a subject that incurred trauma to the head or other organ or tissue.

18. The method of claim 16 , wherein the pharmaceutical composition is administered after a medical procedure.

19. The method of claim 16 , wherein the pharmaceutical composition is administered in combination with a second anti-inflammatory agent.

20. A method of reducing the symptoms of Alzheimer's Disease or Parkinson's Disease comprising administering an effective amount of a pharmaceutical composition of claim 14 to a subject in need thereof.
