Abstract:
PROBLEM TO BE SOLVED: To obtain a new diaza-spiro[3,5]-nonane derivative useful for treating psychiatric, neurological and physiological disorders, e.g. diseases related to orphanin FQ receptor including anxiety, stress disorder, Alzheimer's disease and depression by dementia, etc. SOLUTION: This compound is shown by formula I (R1 is a 6-12C cycloalkyl substitutable with a lower alkyl or the like; R2 is O or the like; R3 is H, isoindolyl-1,3-dione or the like; R4 is H or the like; a group of formula II is a cyclohexyl substitutable with a lower alkyl or the like) preferably 3,3-bis- hydroxymethyl-7-(cis-4-isopropyl-cyclohexyl)-1-phenyl-1,7-diaza-spiro[ 3,5]nonan-2- one or the like. The compound of formula I is obtained by a process for reductively reducing a compound of formula III (e.g. 4-isopropyl-cyclohexanone or the like) with a compound of formula IV e.g. 3,3-bis-hydroxymethyl-1- phenyl-1,7-diaza-spiro[3,5]nonan-2-one or the like}, etc.
Abstract:
PROBLEM TO BE SOLVED: To obtain a novel compound that is an agonist and antagonist of Orphanin FQ(OFQ) receptor and is useful for treatment of psychological disorder, neurological disorder and physiological disorder. SOLUTION: This is a new compound represented by formula I [R1 is a (substituted) 6-10C cycloalkyl, decahydro-naphthalen-1-yl, indan-1-yl, or the like; R2 is H, a lower alkyl, =O, or a (substituted) phenyl; group A is a (substituted) cyclohexyl or phenyl; X is -CH(OH)-, -C(O)- or the like; Y is -CH2-, -CH=, -N= or the like; a and b mean actual additive bonds], typically (RS)-8-(cis-4- isopropyl-cyclohexyl)-1-phenyl-1,8-diaza-spiro[4.5]decan-4-ol. The compound of formula I is prepared by reductive amination of a compound of formula II with a compound of formula II.
Abstract:
PROBLEM TO BE SOLVED: To obtain a new compound useful for treating diseases associated with an Orphanin FQ(OFQ) receptor such as anxiety disorder and stress disorder, depression, trauma and amnesia due to Alzheimer disease or other dementias. SOLUTION: This compound is represented by formula I (R is H or the like; R is H or the like; R is H or the like; R is H or the like; A is a ring system or the like such as a 5-15C cycloalkyl which may be substituted with a lower alkyl or the like in addition to R ), preferably 8-(decahydro-naphthalen-2- yl)-1-phenyl-1,3,8-triaza-spiro[4.5]decan-4-one or the like. The compound represented by formula I is obtained by reductively aminating a compound represented by formula II [e.g. octahydro-2-(1H)-naphthalenone] with a compound represented by formula III e.g. 1-phenyl-1,3,8-triazaspiro[4.5]decan-4-one} in the presence of a reducing agent such as sodium borohydride in a solvent such as toluene.
Abstract:
PROBLEM TO BE SOLVED: To obtain the subject new compound which is an agonist for OFQ receptor and/or an antagonist useful for treating mental disturbance, nervous disturbance and physiological disorder. SOLUTION: This compound is shown by formula I (R and R are each H, a lower alkyl, etc.; R is phenyl; R is H, a lower alkyl, an acyl, etc.; R and R are each H, a lower alkyl, etc., or bonded together to form a phenyl ring; R and one of R and R can be bonded to form a 6-memered ring; A is a saturated 4- to 7-membered ring containing a hetero atom such as O or S) or its acid addition salt such as 8-(8-chloro-1,2,3,4,-tetrahydro-naphthyl-2)-1- phenyl-1,3,8-triaza-spiro[4,5]decan-4-one. The compound of formula I is obtained by hydrogenating a double bond in a compound of formula II (A' is a 5 to 7-membered ring containing a hetero atom such as O or S). The compound is useful for treating anxiety, stress disorder, depression, traumatic disorder, amnesia caused by Alzheimer's disease or other dementia, epilepsy and convulsion.
