Abstract
1. Bis-(piperazinyl- or homopiperazinyl) alkanes of the general formula I see diagramm : EP0122488,P21,F1 wherein R1 , R2 , R3 and R4 which may be identical to or different from each other, are each hydrogen, alkyl having 1 to 4 carbon atoms, hydroxyl, alkoxy having 1 to 4 carbon atoms, alkanoyloxy having up to 4 carbon atoms, halogen, trihalomethyl, di-C1-4 alkylamino, C1-4 alkoxycarbonyl, nitro, cyano or acyl having 1 to 3 carbon atoms ; R5 and R6 , which may be identical to or different from each other, are each hydrogen, methyl, hydroxyl, carboxyl, C1-4 alkoxycarbonyl, hydroxymethyl, phenyl or p-chlorophenyl, R7 and R8 are each hydrogen or methyl ; j and k are integers from 0 to 3, their sum being no more than 4 ; m and n are integers from 0 to 3, their sum being no more than 4 ; A is -CH2 - or -CH2 CH2 - ; or R5 and R7 together or R6 and R8 together are oxo, provided k or m is other than O ; or R5 and R7 together and R6 and R8 together are oxo, provided k or m are other than O ; R9 and R10 , which may be the same or different, represent hydrogen or from one to four methyl substituents on the carbon atoms of the piperazine ring (A = -CH2 -) ; R11 , R12 , R13 and R14 , which may be identical to or different from each other, are each hydrogen or methyl ; or R11 and R12 together and/or R13 and R14 together are oxo ; and X is alkylene of 1 to 2 carbon atoms, optionally hydroxy-substituted with the proviso that when A = -CH2 -, R1 to R14 are hydrogen and j, k, m and n are each zero, then X cannot be 1,2-ethylenediol, and physiologically acceptable acid addition salts thereof.
