Definitions

  • This invention relates to 4-(aminoalkoxy)-lH-benzoimidazoles which have dopamine D 2 agonist activity and thus are useful in the treatment of schizophrenia, Parkinson's disease, Tourette's syndrome and drug or alcohol addiction.
  • 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). As such, they provide functional modulation of the dopamine systems of the brain without the excessive blockade of the postsynaptic dopamine receptors which have been observed to be responsible for the serious side effects frequently exhibited by agents found otherwise clinically effective for the treatment of schizophrenia.
  • the compounds of this invention were also found to have high intrinsic activity and therefore they can behave as the natural neurotransmitter i.e. as full agonists. As such, they are useful in the treatment of diseases having abnormal concentrations of dopamine could be used as dopamine surrogates possibly in the treatment of Parkinson's disease.
  • the compounds of this invention are essentially free from extrapyramidal side effects (EPS). DESCRIPTION OF THE PRIOR ART
  • JP 02306916A claims a class of benzazole compounds of the formula below, where
  • Ri includes -(O-A) m -NR 4 R 5 where A is lower alkylene, m is 0 or 1, R 4 and R 5 include hydrogen, phenyl(lower)alkyl, or NR 4 R 5 is a 5-6 membered saturated or unsaturated heterocycle and R 2 includes phenyl optionally substituted by 1-3 substituents selected from optionally halogenated lower alkoxy, lower alkyl, hydroxy, halogen or aminoalkoxy.
  • R 4 is methyl, cyano, carboxamido or aminomethyl
  • R 5 is H or alkyl
  • R 6 is alkyl or cycloalkyl or R 5 and R 6 completes a cyclohexane ring which are useful for the treatment of circulatory disorders and shock.
  • Rl is hydrogen, trifluoromethyl, pentafluoroethyl, heptafluoropropyl, straight- chain or branched alkyl group having up to 6 carbons or benzyl optionally substituted by one to three substituents selected from halogen, amino, nitro, hydroxy, C ⁇ -C 6 alkoxy; R 2 is hydrogen or C ⁇ -C 6 alkyl.
  • the pharmaceutically acceptable acid addition salt having the utility of the free base are prepared by methods well known to the art with both inorganic or organic acids, including but not limited to 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.
  • inorganic or organic acids including but not limited to fumaric, maleic, benzoic, ascorbic, pamoic, succinic, bis
  • 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 D2 receptor and are thereby useful in the treatment of alcohol and drug addiction.
  • the compounds of this invention effect the synthesis of the neurotransmitter dopamine and thus are useful in the treatment of dopaminergic disorders such as schizophrenia, Parkinson's disease, Tourette's Syndrome, alcohol addiction, cocaine addiction, and addiction to analagous drugs.
  • Applicable solid carriers for pharmaceutical compositions containing the compounds of this invention can include one or more substances which may also act as flavoring agents, lubricants, solubilizers, suspending agents, fillers, glidants, compression aids, binders or tablet-disintergrating agents or an encapsulating material.
  • 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 active ingredient of this invention can be dissolved or suspended in a pharmaceutically acceptable liquid carrier such as water, an organic solvent, a mixture of both or pharmaceutically acceptable oils or fat.
  • the liquid carrier can contain other suitable pharmaceutical additives such as solubilizers, emulsifiers, buffers, preservatives, sweeteners, flavoring agents, suspending agents, thickening agents, colors, viscosity regulators, stabilizers or osmo-regulators.
  • suitable examples of liquid carriers for oral and parenteral administration include water (particularly containing additives as above e.g.
  • cellulose derivatives preferably sodium carboxymethyl cellulose solution
  • alcohols including monohydric alcohols and polyhydric alcohols e.g. glycols
  • oils e.g. fractionated coconut oil and arachis oil
  • the carrier can also be an oily ester such as ethyl oleate and isopropyl myristate.
  • Sterile liquid carriers are used in sterile liquid form compositions for parenteral administration.
  • 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.
  • the variables involved include the specific psychosis and the size, age and response pattern of the patient.
