Definitions

  • the present invention generally relates to substituted araIky1amines, and more particularly to 2- alkylamino-3' ,4 '-methylenedioxypropiophenones with bio ⁇ logical activity such as central nervous system pharma ⁇ cological activity.
  • R is H, normal alkyl C_ to C 6 , isopropyl, isobutyl, sec-butyl, t-butyl, allyl, propargyl, or cyclopropyl, and R 2 is H.
  • a preferred embodiment is the compound where R x is a methyl group and R 2 is H:
  • the carbon atom of 2-methylamino-3 ' ,4 '- methylenedioxypropiophenone that is beta to the carbonyl function is chiral, so that this target compound can exist in either of two optical forms, although the racemic mixture can be used.
  • Acute therapeutic levels of the Formula II embodiments are expected to be between about 100 and 150 mg for oral administration.
  • the compounds have central nervous system activity, particularly anti-depressant and anti-Parkinson properties, and are also useful in vitro for diagnostic and assay applications, such as measuring serotonin or dopamine uptake sites.
  • a preferred embodiment is the compound where Rj is a methyl group and R 2 is H:
  • Compounds of Formula I bind to the serotonin uptake site. They also bind to the dopamine uptake site. Compounds of Formula I and their physiologically acceptable acid addition salts can, therefore, be used as biologically active compounds and also as intermediate products for the preparation of other biologically active compounds.
  • Acid addition salts may be formed by reaction with either inorganic or organic acids.
  • inorganic acids for example sulfuric acid, hydrogen halide acids, such as hydrochloric acid or hydrobromic acid, phosphoric acids, such as ortho- phosphoric acid, nitric acid, or sulfamic acid, and also organic acids, in particular aliphatic, alicyclic, araliphatic, aromatic, or heterocyclic monobasic or polybasic carboxylic, sulfonic or sulfuric acids, such as formic acid, acetic acid, propionic acid, pivalic acid, diethylacetic acid, malonic acid, succinic acid, pimelic acid, fumaric acid, maleic acid, lactic acid, tartaric acid, malic acid, benzoic acid, salicyclic acid, 2- phenylpropionic acid, citric acid, gluconic acid, ascorbic acid, nicotinic acid, isonicotinic acid, methanesulf
  • the invention further relates to the use of the compounds of Formula I and their physiologically acceptable salts for the preparation of pharmaceutical formulations.
  • they can be brought into a suitable dosage form together with at least one excipient or adjuvant and, if appropriate, in combination with one or more other active compound(s) .
  • an "agonist” is a chemical compound that mimics the action of the endogenous neurotransmitter at receptors.
  • serotonin agonists are chemical substances that bind to and mimic the action of serotonin on serotonin receptors (when direct-acting) .
  • uses for serotonin receptor agonists are as research and diagnostic tools.
  • the inventive compounds can be used to measure serotonin and dopamine uptake sites in a sample, for example, by radiolabelling as is known to the art.
  • the formulations can further include excipients, particularly when formulating for pharmaceutical uses.
  • Suitable excipients are organic or inorganic substances which are suitable for enteral (for example oral) or parenteral administration or for local application, and which do not react with the new compounds, for example water, vegetable oils, benzyl alcohols, polyethylene glycols, gelatins, carbohydrates, such as lactose or starch, magnesium stearate, talc or petroleum jelly.
  • Tablets, dragees, capsules, syrups, elixirs, drops or suppositories are especially used for enteral administration; solutions, preferably oily or aqueous solutions, and also suspensions, emulsions or implants are especially used for parenteral administration.
  • compositions of this invention are water soluble salts, isotonic and sterile solutions can readily be made and used, for example, for the preparation of solutions suitable for injection.
  • the formulations indicated can be sterilized and/or can contain adjuvants, such as lubricants, preservatives, stabilizing agents and/or wetting agents, emulsifiers, salts for regulating the osmotic pressure, buffer substances, colorants, flavoring substances and/or aroma generating substances. If desired, they can also contain one or more additional active compounds, for example one or more vitamins or mineral supplements.
  • the invention further relates to the use of the compounds of Formula I and their physiologically acceptable acid addition salts in combating diseases, particularly depressions of various etiologies and symptomatologies, and to their use in the therapeutic treatment of the human or animal body.
  • the substances of this invention are generally administered in a manner analogous to that of known psychopharmacological agents which are commercially available (for example Imipramine), in dosages generally ranging from about 2-500 mg, particularly of 10-50 mg, per dosage unit.
  • the daily dosage is preferably about 0.05 to 10 mg/kg of body weight.
  • the particular dose for each specific patient depends, however, on a very wide variety of factors, for example on the activity of the particular compound employed, on the age, body weight, general state of health, sex, and diet of the patient, on the time and route of administration, on the excretion rate and combination of medicaments and on the severity of the particular disease to which the therapy applies. Oral administration is preferred.
  • a TLC analysis (silica gel, methylene chloride/hexane) showed the distilled product to be largely carbinol, with two impurities that had Rf's greater than that of the product.
  • a solution was made of 10 g potassium dichromate in 65 mL water containing 7 mL concentrated sulfuric acid. This was vigorously stirred, and cooled with an external water bath. A total of 11.7 g of l-(3,4- methylenedioxyphenyl)-l-propanol was added without solvent, dropwise, over the course of 0.5 h, then heated on the steambath for an additional hour. The reaction mixture was poured into 2 L water, acidified with hydrochloric acid, and extracted with 3x100 mL methylene chloride.
  • the reaction mixture was clarified by filtration and the inorganic solids washed with additional methylene chloride.
  • the deep green combined filtrate and washings were filtered through a methylene chloride wetted bed of silica gel yielding a nearly colorless clear filtrate. This was stripped of solvent under vacuum, and the residue, 47.4 g, was distilled bulb-to-bulb.
  • the product distilled at 100-140°C at 0.15 mm/Hg yielding 42.87 g of 2-bromo-3' ,4'-methylenedioxypropiophenone as a pale amber oil that set up to a crystalline solid.
  • the GC-MS analysis showed the desired ketone as the major product (parent peaks, 256-258; major fragment 147, methylene- dioxybenzoyl; 121, methylenedioxyphenyl, confirming the chain bromination of the propiophenone).
  • a minor impurity was 2-chloro-3' ,4 '-methylenedioxypropiophenone, seen with parent peaks at 212/214, and the major peaks again at 149 and 121. It probably arose from the methylene chloride solvent, and does not interfere in any way with the subsequent aminative reaction.
