Definitions

  • the present invention is related to new carboxamido-(3 ,2N)-carbocyclic-2-amino- 1,2,3,4-tetrahydronaphthylene derivatives, to processes for preparing such compounds, pharmaceutical preparation of such compounds and the use of such compounds in manufacture of a pharmaceutical preparation.
  • Psychiatric diseases are thought to be due to dysfunctions in monoaminergic neuronal systems, particularly those involving serotonin (5-HT) and dopamine (DA).
  • Schizophrenia is thought to be due to hyperactivity in DA systems.
  • DA antagonists Dopamine autoreceptors depress DA neuron firing rates, DA synthesis and release.
  • DA autoreceptor agonists can also be expected to be anti-psychotics.
  • DA agonists are also useful for treating Parldnsonism, a disease caused by degeneration of DA neurons, and hyperprolactinemia, since DA agonists depress prolactin release.
  • Dopamine autoreceptor antagonists are a new class of drug that increase release of DA by releasing the DA neuron from autoreceptor control. Thus, these drugs can be expected to be useful in conditions treatable with amphetamine and other similar stimulants which directly release DA. However, because DA autoreceptor agonists will be much milder stimulants because, rather than directly releasing DA, they simply increase the release associated with the normal DA activity by releasing the cell from autoreceptor control. Thus, DA autoreceptor antagonists can be expected to be useful in treating overeating, attention deficit disorders, psychiatric, cognitive and motor retardation in demented and elderly patients, and in treating nausea and dizziness with space travel.
  • the compounds of the present invention have a variety of effects at the DA receptors, and offer a variety of utilities associated with those activities.
  • Drugs acting on central dopamine transmission are clinically effective in treating a variety of central nervous system disorders such as parldnsonism, schizophrenia, and manic-depressive illness.
  • parldnsonism for example, the nigro-neostriatal hypofunction can be restored by an increase in postsynaptic dopamine receptor stimulation.
  • schizophrenia the condition can be normalized by achieving a decrease in postsynaptic dopamine receptor stimulation.
  • Classical anti-psychotic agents directly block the postsynaptic dopamine receptor. The same effect can be achieved by inhibition of intraneuronal presynaptic events essential for the maintenance of adequate neuro- transmission, transport mechanism and transmitter synthesis.
  • Direct dopamine receptor agonists like apomoiphine, are able to activate the dopamine autoreceptors as well as the post synaptic dopamine receptors.
  • the effects of autoreceptor stimulation appear to predominate when apomoiphine is administered at low doses, whereas at higher doses the attenuation of dopamine transmission is outweighed by the enhancement of postsynaptic receptor stimulation.
  • the anti-psychotic and anti- dyskinetic effects in man of low doses of apomoiphine are likely due to the autoreceptorstimulator properties of this dopamine receptor agonist. This body of knowledge indicates dopamine receptor stimulants with a high selectivity for central nervous dopamine autoreceptors would be valuable in treating psychiatric disorders.
