Definitions

  • This invention relates to 4-aminoethoxyindazole derivatives having dopamine D 2 agonist activity useful for antipsychotic effects and antiparkinsonism.
  • Intrinsic activity is predicted using the ratio of the "low-affinity agonist" (LowAg) state of the receptor and the "high-affinity agonist” (HighAg) state of the receptor, i.e. LowAg/HighAg. These ratios correlate with the agonist, partial agonist, and antagonist activities of a given compound, which activities characterize a compounds ability to elicit an antipsychotic effect.
  • the compounds of this invention are dopamine agonists various degrees of intrinsic activity some of which are selective autoreceptor agonists, and therefore partial agonist (i.e. activate only autoreceptors versus postsynaptic D 2 dopamine receptors).
  • the compounds of this invention are essentially free from extrapyramidal side effects (EPS).
  • EPS extrapyramidal side effects
  • the compounds of this invention are 4-aminoethoxy-benzimidazole derivatives which are illustrated by Formula I below.
  • Y is hydrogen, halogen, or -C ⁇ alkoxy;
  • R 1 is hydrogen or C ⁇ -C 6 alkyl;
  • X is methylene, oxygen or carbonyl;
  • the compounds of this Formula I also may be used in the form of a pharmaceutically acceptable acid addition salt having the utility of the free base.
  • Such salts prepared by methods well known to the art are formed with both inorganic or organic acids, for example: fumaric, maleic, benzoic, ascorbic, pamoic, succinic, bismethylenesalicylic, methanesulfonic, ethanedisulfonic, acetic, oxalic, propionic, tartaric, salicyclic, citric, gluconic, lactic, malic, mandelic, cinnamic, citraconic, aspartic, stearic, palmitic, itaconic, glycolic, p-aminobenzoic, glutamic, benzene-sulfonic, hydrochloric hydrobromic, sulfuric, cyclohexylsulfamic, phosphoric and nitric acids.
  • the compounds of this invention are dopamine autoreceptor agonists, that is, they serve to modulate the synthesis and release of the neurotransmitter dopamine. They are thus useful for treatment of disorders of the dopaminergic system, such as schizophrenia,
  • Parkinson's disease and Tourette's syndrome Such agents are partial agonists at the postsynaptic dopamine D 2 receptor and are thereby useful in the treatment of alcohol and drug addiction.
  • Affinity for the dopamine autoreceptor was established by a modification of the standard experimental test procedure of Seemen and Schaus, European Journal of Pharmacology 203, 105-109, 1991, wherein homogenized rat striatal brain tissue is incubated with ⁇ H-quinpirole (Quin.) and various concentrations of test compound, filtered and washed and counted in a Betaplate scintillation counter.

  • the carrier is a finely divided solid which is in admixture with the finely divided active ingredient.
  • the active ingredient is mixed with a carrier having the necessary compression properties in suitable proportions and compacted in the shape and size desired.
  • the powders and tablets preferably contain up to 99% of the active ingredient.
  • Suitable solid carriers include, for example, calcium phosphate, magnesium stearate, talc, sugars, lactose, dextrin, starch, gelatin, cellulose, methyl cellulose, sodium carboxymethyl cellulose, polyvinylpyrrolidine, low melting waxes and ion exchange resins.
  • Liquid carriers may be used in preparing solutions, suspensions, emulsions, syrups and elixirs.

  • the carrier can also be an oily ester such as ethyl
  • Liquid pharmaceutical compositions which are sterile solutions or suspensions can be utilized by, for example, intramuscular, intraperitoneal or subcutaneous injection. Sterile solutions can also be administered intravenously. Oral administration may be either liquid or solid composition form.
  • the pharmaceutical composition is in unit dosage form, e.g. as tablets or capsules.
  • the composition is sub-divided in unit dose containing appropriate quantities of the active ingredient;
  • the unit dosage forms can be packaged compositions, for example packeted powders, vials, ampoules, prefilled syringes or sachets containing liquids.
  • the unit dosage form can be, for example, a capsule or tablet itself, or it can be the appropriate number of any such compositions in. package form.
  • the dosage to be used in the treatment of a specific psychosis must be subjectively determined by the attending physician.
