Abstract

Abstract There are disclosed new hexamethylene-bis-biguanides having antibacterial activity, and two processes for the preparation thereof. The new compounds have the general formula ##STR1## wherein R represents H, and R' represents an hexyl or pentyl group being substituted with one or two methyl groups, or represents a cycloalkyl group having more than 6 carbon atoms, a lower-alkyl-cycloalkyl group or a cycloalkyl-lower-alkyl group, or R and R' together with the adjacent nitrogen atom represent an azabicyclo(3,2,2)-nonane double ring.

Claim 1
Independent Claim 45 words
A compound of the formula ##STR6## wherein R represents H and R' is selected from the group consisting of 1-adamantyl, 2-norbonyl and cyclohexylmethyl or wherein R and R' together with the adjacent nitrogen atom form a 3-azabicyclo(3,2,2)-nonane double ring and pharmaceutically acceptable acid addition salts.
Claim 2
Dependent Claim 45 words
A compound of the formula ##STR6## wherein R represents H and R' is selected from the group consisting of 1-adamantyl, 2-norbonyl and cyclohexylmethyl or wherein R and R' together with the adjacent nitrogen atom form a 3-azabicyclo(3,2,2)-nonane double ring and pharmaceutically acceptable acid addition salts.
Claim 3
Dependent Claim 9 words
Compound according to claim 1, wherein R'=1-adamantyl and R=H.
Claim 4
Dependent Claim 9 words
Compound according to claim 1, wherein R'=2-norbornyl and R=H.
Claim 5
Dependent Claim 9 words
Compound according to claim 1, wherein R'=cyclohexylmethyl and R=H.
Claim 6
Dependent Claim 21 words
Compound according to claim 1, in which R' and R together with the adjacent nitrogen atom form a 3-azabicyclo(3,2,2)-nonane double ring.
