Title:Compounds active at a novel site on receptor-operated calcium channels useful for treatment of neurological disorders and diseases
Abstract: Method and compositions for treating a patient having a neurological disease or disorder, such as stroke, head trauma, spinal cord injury, spinal cord ischemia, ischemia- or hypoxia-induced nerve cell damage, epilepsy, anxiety, neuropsychiatric or cognitive deficits due to ischemia or hypoxia such as those that frequently occur as a consequence of cardiac surgery under cardiopulmonary bypass, or neurodegenerative diseases such as Alzheimer's Disease, Huntington's Disease, Parkinson's Disease, or amyotrophic lateral sclerosis (ALS).
Inventor(s): Mueller; Alan L. (Salt Lake City, UT), Moe; Scott T. (Salt Lake City, UT)
Assignee: NPS Pharmaceuticals, Inc. (Parsippany, NJ)
Filing Date:Feb 13, 2006
Application Number:11/352,630
Claims:1. A compound of the formula: ##STR00192## wherein: X is independently selected from the group consisting of: --H, --Br, --Cl, --F, --I, --CF.sub.3, alkyl, --OH, --OCF.sub.3, --O-alkyl, and --O-acyl; R.sub.1 is independently selected from the group consisting of: --H, lower alkyl, and --O-acyl; R.sub.2 is independently selected from the group consisting of: --H, alkyl, and hydroxyalkyl, or both R.sub.2s together are imino; R.sub.4 is phenoxy which is optionally substituted with --F, --Cl, --Br, --I, --CF.sub.3, alkyl, --OH, --OCF.sub.3, --O-alkyl, or --O-acyl; provided that when X is H, then R.sub.4 is substituted with at least one of: meta-fluoro, meta-chloro, meta-methyl, meta-OH, ortho-fluoro, ortho-chloro, ortho-methyl, or ortho-OH; m is independently an integer from 1 to 5; and pharmaceutically acceptable salts and complexes thereof.

2. A compound of the formula: ##STR00193## wherein: X is independently selected from the group consisting of: --H, --Br, --Cl, --F, --I, --CF.sub.3, alkyl, --OH, --OCF.sub.3, --O-alkyl, and --O-acyl; R.sub.1 is independently selected from the group consisting of: --H, lower alkyl, and --O-acyl; R.sub.2 is independently selected from the group consisting of: --H, alkyl, and hydroxyalkyl, or both R.sub.2s together are imino; R.sub.4 is phenoxy which is optionally substituted with --F, --Cl, --Br, --I, --CF.sub.3, alkyl, --OH, --OCF.sub.3, --O-alkyl, or --O-acyl; provided that when X is H, then R.sub.4 is substituted with at least one of: meta-fluoro, meta-chloro, meta-methyl, meta-OH, ortho-fluoro, ortho-chloro, or ortho-OH; m is independently an integer from 1 to 5; and pharmaceutically acceptable salts and complexes thereof.

3. A compound of the formula: ##STR00194## wherein: X is independently selected from the group consisting of: --Br, --Cl, --F, --I, --CF.sub.3, alkyl, --OH, --OCF.sub.3, --O-alkyl, and --O-acyl; R.sub.1 is independently selected from the group consisting of: --H, lower alkyl, and --O-acyl; R.sub.2 is independently selected from the group consisting of: --H, alkyl, and hydroxyalkyl, or both R.sub.2s together are imino; R.sub.4 is phenoxy which is optionally substituted with --F, --Cl, --Br, --I, --CF.sub.3, alkyl, --OH, --OCF.sub.3, --O-alkyl, or --O-acyl; m is independently an integer from 1 to 5; and pharmaceutically acceptable salts and complexes thereof.

4. A pharmaceutical composition, comprising a compound as in any of claims 1, 2, and 3, and a pharmaceutically acceptable carrier.

5. The pharmaceutical composition of claim 4, wherein said pharmaceutical composition is adapted for the treatment of a neurological disease or disorder.

6. The pharmaceutical composition of claim 4, wherein said pharmaceutical composition is adapted to provide neuroprotection to a patient.

7. The pharmaceutical composition of claim 4, wherein said compound is a hydrochloride salt.

8. A method for treating a patient having a neurological disease or disorder, comprising administering a compound as in any of claims 1, 2, and 3, wherein said neurological disease or disorder is selected from the group consisting of stroke, head trauma, spinal cord injury, epilepsy, anxiety, Alzheimer's disease, Huntington's disease, Parkinson's disease, and arnyotrophic lateral sclerosis.

9. The method of claim 8, wherein said neurological disease or disorder is stroke.

10. The method of claim 8, wherein said neurological disease or disorder is head trauma.

11. The method of claim 8, wherein said neurological disease or disorder is spinal cord injury.

12. The method of claim 8, wherein said neurological disease or disorder is epilepsy.

13. The method of claim 8, wherein said neurological disease or disorder is anxiety.

14. The method of claim 8, wherein said neurological disease or disorder is Alzheimer's disease.

15. The method of claim 8, wherein said neurological disease or disorder is Huntington's disease.

16. The method of claim 8, wherein said neurological disease or disorder is Parkinson's disease.

17. The method of claim 8, wherein said neurological disease or disorder is amyotrophic lateral sclerosis.

18. The method of claim 9, wherein said stroke is global ischemic.

19. The method of claim 9, wherein said stroke is hemorrhagic.
