and a prodrug, solvate or hydrate of any of structures (a)-(b).
2. A pharmaceutical dosage form comprising the apocynin derivative or apocynin derivative dimer of claim 1 and a pharmaceutically suitable carrier system.
3. The pharmaceutical dosage form of claim 2 , wherein the dosage form comprises an oral, injection, infusion, inhalation, transdermal, or implant dosage form.
4. A method of administering a therapeutically effective amount of an apocyanin derivative or apocyanin derivative dimer of claim 1 to a mammal, to obtain an increase in the amount of dopamine in the brain of the mammal or an increase in the amount of dihydroxyphenylacetic acid (DOPAC) in the mitochondria of the mammalian brain cell.
5. The method of claim 4 , wherein the apocynin derivative or apocynin derivative dimer is orally administered.
6. The apocynin derivative according to claim 1 , wherein the apocynin derivative has any one of the following structures:
or wherein the apocynin derivative is a prodrug, solvate or hydrate of any of the preceding structures.
