39270-39-8, Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent£¬Which mentioned a new discovery about 39270-39-8
Pyridyl- and/or pyridoyl-(piperid-4-yl) ureas and analogues thereof
The invention concerns the preparation of compounds of formula STR1 and acid addition and quaternary ammonium salts thereof, wherein the dotted line represents an optional bond, Ar represents a ring system of formula STR2 in which Q is O, S, –CR7 =CR8 –, –N=CR8 — and –NM=N–; R4, R5 and R6 ; and R7 and R8 when present, each represent hydrogen or a substituent selected from lower alkyl, lower alkenyl, lower alkoxy, NO2, NH2, haloloweralkyl, hydroxyloweralkyl, aminoloweralkyl, substituted amino, halogen, loweralkoxycarbonyl, cyano, CONH2 and hydroxy; and additionally either R4 and R5 when adjacent or R6 and R8 when adjacent, together with the carbon atoms to which they are attached also represent a fused five or six membered carbocylic or heterocyclic ring optionally carrying one or more substituents as defined above; R is an optionally substituted aryl or heteroaryl radical or a cycloalkyl radical containing 5 to 7 carbon atoms; R1, R2, R3 and R9 are each hydrogen or a lower alkyl group; n is 0 or 1; X is =O, =S, or =NY; Y is –O– or a direct bond and Z is — CO– or –CH2 –, with the proviso that when Ar is unsubstituted phenyl and R9 is hydrogen then v is –O–. The compounds of formula I exhibit psychotropic activity and are useful as antidepressants.
