Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
136 words
A compound of the formula ##STR8## wherein each of Ph and Ph' is phenyl, unsubstituted or monosubstituted by lower alkyl, halogeno or trifluoromethyl; each of R 1 and R 2 are hydrogen, alkyl with up to 3 carbon atoms, or both (R 1 +R 2 ) together represent alkylene with up to 3 carbon atoms; each of m and n is an integer from 1 to 3; p is an integer from 2 to 7, whereby C p H 2p separates the adjacent nitrogen atoms by at least 2 carbon atoms; and A is alkylene or alkenylene with 2-7 carbon atoms, 4 to 7 ring-membered mono- or bicyclo-alkylene or -alkenylene, or 4 to 7 ring-membered 2-spiro-cycloalkane- (ethylene or 1,3-propylene) unsubstituted or ring-substituted by up to three lower alkyls, or a therapeutically acceptable acid addition salt thereof.
Claim 2
Dependent Claim
136 words
A compound of the formula ##STR8## wherein each of Ph and Ph' is phenyl, unsubstituted or monosubstituted by lower alkyl, halogeno or trifluoromethyl; each of R 1 and R 2 are hydrogen, alkyl with up to 3 carbon atoms, or both (R 1 +R 2 ) together represent alkylene with up to 3 carbon atoms; each of m and n is an integer from 1 to 3; p is an integer from 2 to 7, whereby C p H 2p separates the adjacent nitrogen atoms by at least 2 carbon atoms; and A is alkylene or alkenylene with 2-7 carbon atoms, 4 to 7 ring-membered mono- or bicyclo-alkylene or -alkenylene, or 4 to 7 ring-membered 2-spiro-cycloalkane- (ethylene or 1,3-propylene) unsubstituted or ring-substituted by up to three lower alkyls, or a therapeutically acceptable acid addition salt thereof.
Claim 3
Dependent Claim
126 words
A compound as claimed in claim 1, in which formula each of Ph and Ph' is phenyl, (lower alkyl)-phenyl, (halogen)-phenyl or (trifluoromethyl)-phenyl, each of R 1 and R 2 are hydrogen, alkyl with up to 3 carbon atoms, or both (R 1 +R 2 ) together represent alkylene with up to 3 carbon atoms; each of m and n is an integer from 1 to 3; p is an integer from 2 to 7, whereby C p H 2p separates the adjacent nitrogen atoms by at least 2 carbon atoms; and A is alkylene or alkenylene with 2-7 carbon atoms, 4 to 7 ring-membered mono- or bicyclic 1,2- or 1,3-cycloalkylene or -cyclo-alkenylene, or 4 to 7 ring-membered 2-spirocycloalkane-1,3-propylene, or a therapeutically acceptable acid addition salt thereof.
Claim 4
Dependent Claim
121 words
A compound as claimed in claim 1, in which formula each of Ph and Ph' is phenyl, (lower alkyl)-phenyl, (halogeno)-phenyl or (trifluoromethyl)-phenyl; each of R 1 and R 2 is hydrogen or both (R 1 +R 2 ) together are alkylene with 2 or 3 carbon atoms; each of m and n is the integer 2 or 3; p is an integer from 2 to 4, whereby C p H 2p separates the adjacent nitrogen atoms by at least 2 carbon atoms; and A is straight or branched alkylene or alkenylene with 2-7 carbon atoms, 4 to 7 ring-membered mono- or bicyclic 1,2- or 1,3-cycloalkylene or -chcloalkeneylene, or 4 to 7 ring-membered 2-spirocycloalkane-1,3-propylene, or a therapeutically acceptable acid addition salt thereof.
Claim 5
Dependent Claim
79 words
A compound as claimed in claim 1 and corresponding to the formula ##STR9## wherein each of R and R' is hydrogen, alkyl with 1-4 carbon atoms, halogeno or trifluoromethyl; each of R" is hydrogen or both R" together represent ethylene; q is 2 to 4, r is 0 or 1 and each of R"', is alkyl with 1-4 carbon atoms, or both R"' together stand for alkylene with 3-5 carbon atoms, or a therapeutically acceptable acid addition salt thereof.
Claim 6
Dependent Claim
67 words
