New 1-aminomethyl-4-oxazolylalkyl-cyclohexane derivatives, useful for treating e.g. pain, depression and urinary incontinence, bind to mu-opioid receptors

摘要

1-aminomethyl-4-oxazolylalkyl-cyclohexane derivatives (I), as racemates, enantiomers, diastereomers (and mixtures), bases and salts with acids are new. 1-aminomethyl-4-oxadiazolylalkyl-cyclohexane derivatives of formula (I), as racemates, enantiomers, diastereomers (and mixtures), bases and salts with acids are new. n : 0-2; R 1>aryl or heteroaryl attached through 1-3C alkyl, both optionally substituted, one or more times; R 2>aryl or heteroaryl, both optionally substituted, one or more times, and/or attached through a 1-3C alkyl; R 3> and R 4>1-6C alkyl (optionally unsaturated, linear or branched, optionally substituted one or more times) or aryl (optionally substituted one or more times and/or attached through 1-3C alkyl) or together they complete a 5-7 membered ring, saturated or unsaturated (but not aromatic), optionally containing an additional heteroatom (S, O or N), optionally substituted one or more times, and the ring may be fused to an aromatic ring; R 5> and R 6>hydrogen or 1-6C alkyl (optionally unsaturated and/or branched), but are not both hydrogen, or together they complete CH 2CH 2OCH 2CH 2 or (CH 2) 3-6; R 7> and R 8>1-4C alkyl (optionally unsaturated and/or substituted one or more times) or (hetero)aryl optionally substituted one or more times and attached through 1-3C alkyl, or together they form a 5-7 membered ring as defined above. An independent claim is included for a method for preparing (I) by reacting aldehyde (A), with amine NHR 4>R 3> (B) and isonitrile amide NC-CHR 1>CONR 7>R 8> (C) in organic solvent, e.g. (m)ethanol, at 30-100, preferably 40-80, [deg]C for 1-10 hours. [Image] [Image] ACTIVITY : Analgesic; Antidepressant; Uropathic; Antidiarrheic; Antipruritic; Antialcoholic; Tranquilizer. MECHANISM OF ACTION : (I) bind to the mu -opioid receptors. The compound [{4-[(4-benzyl-5-pyrrolidin-1-yl-oxazol-2-yl)piperidin-1-ylmethyl]-cyclohexyl}-(4-fluorophenyl)methyl]cyclohexyl}methyl)methylphenylamine caused 76% inhibition of the human mu receptor at a concentration of 1 mu M.
