View Patent ↗The present invention relates to compounds that are antagonists of the orexin-1 receptor. The compounds have the structural formula (I) defined herein. The present invention also relates to processes for the preparation of these compounds, to pharmaceutical compositions comprising them, and to their use in the treatment of diseases or disorders associated with orexin-1 receptor activity.
1. A compound which is selected from
N,6-dimethyl-3-(2H-1,2,3-triazol-2-yl)-N-[(2S)-1-{[5-(trifluoro methyl)pyrazin-2-yl]amino}propan-2-yl]pyridine-2-carboxamide; and
N,6-dimethyl-3-(2H-1,2,3-triazol-2-yl)-N-[(2S)-1-{[5-(trifluoro methyl)pyrimidin-2-yl]amino}propan-2-yl]pyridine-2-carboxamide;
or a pharmaceutically acceptable salt or solvate thereof.
2. A compound according to claim 1 , which is
N,6-dimethyl-3-(2H-1,2,3-triazol-2-yl)-N-[(2S)-1-{[5-(trifluoro methyl)pyrazin-2-yl]amino}propan-2-yl]pyridine-2-carboxamide;
or a pharmaceutically acceptable salt or solvate thereof.
3. A compound according to claim 1 , which is
N,6-dimethyl-3-(2H-1,2,3-triazol-2-yl)-N-[(2S)-1-{[5-(trifluoro methyl)pyrimidin-2-yl]amino}propan-2-yl]pyridine-2-carboxamide;
or a pharmaceutically acceptable salt or solvate thereof.
4. A pharmaceutical composition comprising a compound according to claim 2 , or a pharmaceutically acceptable salt or solvate thereof, and one or more pharmaceutically acceptable excipients.
5. A method of treating a disease or condition selected from schizophrenia and other psychotic disorders (e.g., psychotic disorder, psychosis or schizoaffective disorder); dementia and other cognitive disorders; anxiety disorders (e.g., generalized anxiety disorder, post-traumatic stress disorder, panic disorders, acute stress disorder, social anxiety disorder, phobias including agoraphobia, obsessive compulsive disorder, trichotillomania or body dysmorphic disorder); mood disorders (e.g., depressive disorders, major depressive disorders, bipolar disorders including bipolar I and II, bipolar mania, bipolar depression); addiction including substance dependence (e.g., cocaine, opiates, cannabis or prescription drug dependence), alcohol dependence, nicotine dependence or gambling disorder; eating disorders (e.g., binge eating, bulimia nervosa, anorexia nervosa or obesity); sleep disorders (e.g., rapid eye movement sleep disorder); disorders usually first diagnosed in infancy, childhood, or adolescence (e.g., attention-deficit disorder, autistic spectrum disorders, Rett syndrome, Fragile X syndrome, Asperger syndrome and disruptive behavior disorders); restless leg syndrome; pain (e.g., neuropathic pain including chemotherapy induced pain or migraine); osteoporosis and neurodegenerative disorders (e.g., Parkinson's or Alzheimer's disease), said method comprising administering to a subject in need of such treatment a therapeutically effective amount of a compound according to claim 2 , or a pharmaceutically acceptable salt or solvate thereof.
6. A pharmaceutical composition comprising a compound according to claim 3 , or a pharmaceutically acceptable salt or solvate thereof, and one or more pharmaceutically acceptable excipients.
7. A method of treating a disease or condition selected from schizophrenia and other psychotic disorders (e.g., psychotic disorder, psychosis or schizoaffective disorder); dementia and other cognitive disorders; anxiety disorders (e.g., generalized anxiety disorder, post-traumatic stress disorder, panic disorders, acute stress disorder, social anxiety disorder, phobias including agoraphobia, obsessive compulsive disorder, trichotillomania or body dysmorphic disorder); mood disorders (e.g., depressive disorders, major depressive disorders, bipolar disorders including bipolar I and II, bipolar mania, bipolar depression); addiction including substance dependence (e.g., cocaine, opiates, cannabis or prescription drug dependence), alcohol dependence, nicotine dependence or gambling disorder; eating disorders (e.g., binge eating, bulimia nervosa, anorexia nervosa or obesity); sleep disorders (e.g., rapid eye movement sleep disorder); disorders usually first diagnosed in infancy, childhood, or adolescence (e.g., attention-deficit disorder, autistic spectrum disorders, Rett syndrome, Fragile X syndrome, Asperger syndrome and disruptive behavior disorders); restless leg syndrome; pain (e.g., neuropathic pain including chemotherapy induced pain or migraine); osteoporosis and neurodegenerative disorders (e.g., Parkinson's or Alzheimer's disease), said method comprising administering to a subject in need of such treatment a therapeutically effective amount of a compound according to claim 3 , or a pharmaceutically acceptable salt or solvate thereof.
