Dihydroimidazo[2,1-b]thiazole and dihydro-5h-thiazolo[3,2-A]pyrimidines as antidepressant agents

The combination of 3-phenylsulfonyl-8-piperazinyl-1yl-quinoline or a pharmaceutically acceptable salt thereof with a second therapeutic agent, wherein the second therapeutic agent is selected from: (a) a therapeutic agent known to modify cholinergic transmission such as M1 muscarinic receptor agonists or allosteric modulators, M2 muscarinic antagonists, acetylcholinesterase inhibitors, nicotinic receptor agonists or allosteric modulators, 5-HT4 receptor partial agonists or 5HT1A receptor antagonists and NMDA receptor antagonists or modulators, glutamate antagonists, GABA-ergic antagonists, H3 antagonists, putative metabolic/mitochondrial modulators, or disease modifying agents such as .beta. or .gamma.-secretase inhibitors, Tau-targeted therapeutics, .beta.-amyloid aggregation inhibitors and .beta.-amyloid immunotherapies; (b) an antidepressant such as a tricyclic, a MAOI (Monoamine oxidase inhibitor) a SSRI (Selective Serotonin Reuptake Inhibitor), a SNRI (Serotonin and Noradrenaline Reuptake Inhibitor) or a NaSSA (noradrenergeric and specific serotonergic antidepressant); (c) an atypical antipsychotic, for example olanzapine, clozapine, prisperidone, quentiapine, aripriprazole or paliperiden; or (d) a therapeutic agent suitable for use in Attention Deficit Disorders/Hyperactivity Syndrome, e.g. methylphenidate (Ritalin) or dexamfetamine (Dexedrine), and also the use of 3-phenylsulfonyl-8-piperazinyl-1yl-quinoline or a pharmaceutically acceptable salt thereof for the treatment of: a) psychiatric disorders with prominent cognitive deficits e.g. chronic PTSD (Post traumatic stress disorder); b) non-degenerative disorders with prominent cognitive deficits e.g. MS (multiple Sclerosis), post-chemotherapy, post-CABG (Coronary artery bypass graft), post-stroke; and/or c) paediatric disorders e.g. autism, mental retardation and learning disabilities.

Combinations comprising 3-phenylsulfonyl-8-piperazinyl-1yl-Quinoline

A class of quinolinic sulfide derivatives of formula I are potent and specific antagonists at the strychnine insensitive glycine bitding site on the NMDA receptor complex with an pharmacological advantageous profile. They may be useful in treatment or prevention of neuro-degenerative disorders. Particularly, the compounds included in the present invention are especially useful for minimizing damage of the central nervous system arising as a consequence of ischemic or hypoxic condition such as stroke, hypoglycemia, cerebral ischemia, cardiac arrest, and physical trauma. They are also useful in prevention of chronic neurodegenerative disorders including epilepsy, Alzheimer's disease, Huntington's disease and Parkinsonism. By virtue of their NMDA receptor antagonist properties, the present compounds may also use as anticonvulsant, analgesic, antidepressant, anxiolytic, and antischizophrenic agent. Formula I ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, and R are defined in specification.
