Abstract

Provided are methods for promoting axon regeneration of a Central Nervous System (CNS) neuron and promoting nerve function following injury to a CNS neuron, for example, brain and/or spinal cord injury. Axon regeneration in a CNS neuron or nerve function following injury to a CNS neuron can be promoted by administering a necrosis inhibitor either alone or in combination with an apoptosis inhibitor to a subject suffering from a CNS disorder, wherein a symptom of the CNS disorder is axon degeneration.

Claims

1. A method for treating a spinal cord injury in a subject by promoting axon regeneration in a Central Nervous System (CNS) neuron, the method comprising:

exposing the CNS neuron of the subject to an effective amount of a necrostatin and an effective amount of an apoptosis inhibitor thereby to promote the regeneration of the axon of the CNS neuron;

wherein the necrostatin is selected from the group consisting of;

(i) a Nec-1 related compound of Formula I;

2. The method of claim 1, wherein the neuron is ex vivo.

3. The method of claim 1, wherein the neuron is in vivo.

4. The method of claim 1, wherein the CNS neuron is selected from the group consisting of a sensory neuron, a motor neuron, a cortical neuron, a pyramidal neuron, a cerebellar neuron, a hippocampal neuron, and a midbrain neuron.

5. The method of claim 1, wherein the necrostatin is necrostatin-1, necrostatin-2, necrostatin-3, necrostatin-4, necreostatin-5, and necrostatin-7, or a combination thereof.

6. The method of claim 1, wherein from about 0.05 mg to about 2 mg of the necrostatin is administered.

7. The method of claim 1, wherein the apoptosis inhibitor is a pan-caspase inhibitor.

8. The method of claim 7, wherein the pan-caspase inhibitor is zVAD, IDN-6556 or a combination thereof.

9. The method of claim 1, wherein the necrostatin, the apoptosis inhibitor, or both the necrostatin and the apoptosis inhibitor are administered locally.

10. The method of claim 1, wherein the necrostatin, the apoptosis inhibitor, or both the necrostatin and the apoptosis inhibitor are administered systemically.

11. The method of claim 1, wherein the necrostatin, the apoptosis inhibitor, or both the necrostatin and the apoptosis inhibitor are administered sequentially or simultaneously.

12. The method of claim 1, wherein the spinal cord injury is selected from the group consisting of chronic spinal cord injury, acute spinal cord injury, and traumatic spinal cord injury.
