Uses of chemicals to modulate GSK-3 signaling for treatment of bipolar disorder and other brain disorders
Aspects of this invention are related, at least in part, to the use of chemical compounds able to inhibit GSK-3 and/or to stabilize β-catenin and formulations thereof. Some aspects of this invention relate to compositions comprising such compounds. Some aspects of the invention provide methods of using such compounds and/or compositions in the treatment of subjects having a neurological disease and/or psychiatric disorder. Some aspects of this invention provide methods of using ruboxistaurin, enzastaurin, sunitinib, midostaurin, lestaurtinib, 7-hydroxystaurosporine, and/or Chir99021 in the treatment of subjects having a neurological disease and/or psychiatric disorder. In some embodiments, compounds are administered in combination with Lithium.
1. A method for treating bipolar disorder in a subject, comprising administering ruboxistaurin, or a pharmaceutically acceptable salt thereof, to the subject in an effective amount to treat the bipolar disorder based on said subject being indicated or diagnosed to have bipolar disorder, wherein the subject is non-responsive to lithium.
2. The method of claim 1 , further comprising diagnosing bipolar disorder in the subject and administering ruboxistaurin, or a pharmaceutically acceptable salt thereof, to the subject based on this diagnosis.
3. The method of claim 1 , wherein the method does not comprise administering lithium to the subject.
4. The method of claim 1 , further comprising administering an additional compound to said subject, wherein said additional compound is indicated in the treatment of a neurological disease and/or psychiatric disorder.
5. The method of claim 4 , wherein said additional compound is lithium, divalproex sodium, or lamotrigene.
6. The method of claim 5 , wherein lithium is administered at a sub-effective dose.
7. The method of claim 5 , wherein ruboxistaurin is administered at a sub-effective dose.
8. The method of claim 5 , wherein ruboxistaurin is administered at a sub-effective dose, and wherein lithium is administered at a sub-effective dose.
9. A method for treating bipolar disorder in a subject, comprising administering a GSK-3 inhibitor having an IC 50 of less than 1 mM to a subject in an effective amount to treat the bipolar disorder based on said subject being indicated or diagnosed to have bipolar disorder, wherein the subject is non-responsive to lithium.
10. The method of claim 9 , further comprising diagnosing bipolar disorder in the subject and administering the GSK-3 inhibitor to the subject based on this diagnosis.
11. The method of claim 9 , wherein the method does not comprise administering lithium to the subject.
12. The method of claim 9 , further comprising administering an additional compound to said subject, wherein said additional compound is indicated in the treatment of a neurological disease and/or psychiatric disorder.
13. The method of claim 12 , wherein said additional compound is divalproex sodium.
14. The method of claim 12 , wherein said additional compound is lamotrigene.
15. The method of claim 12 , wherein said additional compound is lithium.
16. The method of claim 15 , wherein lithium is administered at a sub-effective dose.
17. The method of claim 15 , wherein the GSK-3 inhibitor is administered at a sub-effective dose.
18. The method of claim 15 , wherein the GSK-3 inhibitor is administered at a sub-effective dose, and wherein lithium is administered at a sub-effective dose.
