This invention relates to a polyether bisbiguanide derivative of the formula:-
or a tautomerthereof, wherein R', R2, R5 and R8, which may be the same or different, are each hydrogen, a 1-16C alkyl radical, a 2-16C alkoxyalkyl radical a 3-12C cycloalkyl radical, a (3-12C cycloalkyl)-(1-4C alkyl) radical, an optionally substituted phenyl, phenyl (1-4C alkyl) or phenyl (1-4C alkoxy) 1-4C alkyl) radical, or R' and R2 and the nitrogen atom to which they are attached, or R5 and R6 and the nitrogen atom to which they are attached, which may be the same or different, are each a I-azetidinyl, 1-pyrrolidinyl, piperidino, hexamethyleneimino, heptamethyleneimino, morpholino or 4-(1-8C alkanoyl)-1-piperazinyl radical; each of which may bear 1-3C alkyl sub- stituents; R3 and R4, which may be the same or different, are each hydrogen or 1-16C alkyl radical, a 3-16C cycloalkyl radical, a (3-12C cyclo-alkyl)-(1-4C alkyl) radical, an optionally substituted phenyl radical, an optionally substituted phenyl (1-4C alkyl) or naphthyl (1-4C alkyl) radical, or an optionally substituted diphenylmethyl radical; R7 and R8 are each hydrogen or a 1-8C alkyl radical; and X is a linking group of the formula:-
wherein Z' and Z2 are each an oxygen or sulphur atom, Y is a polymethylene, p-phenylene, 1,4-phenylene-dimethylene or 1,5-naphthylene radical, a radical of the formula:-
or a polymethylene radical which is interrupted by up to 5 ether oxygen or thioether sulphur atoms, and x and y are integers being 2 or greater, such that the total number of methylene groups in the linking group X is not more than 18; and the acid-addition salts thereof; to processes for their manufacture; and to compositions and methods of use thereof.
