3,5-substituted aminobenzoylguanidines, their use as a medicament or diagnostic and medicament containing them

A benzoylguanidine of the formula I ##STR14## in which:

• one of the substituents R(1), R(2), R(3) or R(4) is:
• an amino group ##STR15## where R(5)=hydrogen or C.sub.(1-6)-alkyl,
• n=zero, 1, 2, 3 or 4,
• R(6)=H, C.sub.1-4)-alkyl, in which a CH.sub.2 group can be replaced by 1 sulfur atom or a group NR(7) where R(7)=hydrogen, methyl or ethyl,
• C.sub.(3-8)-cycloalkyl, phenyl, which is unsubstituted or carries 1, 2 or 3 substituents selected from the group consisting of F, Cl, Br, methyl, methoxy and --NR(8)R(9) where R(8) and R(9) are H, methyl or ethyl, and in which
• R(5) and R(6), together with the nitrogen atom, can also form a 5-, 6- or 7-membered ring in which 1 carbon atom can be replaced by oxygen, S or NR(10) where R(10) is H, C.sub.(1-3)-alkyl or benzyl,
• and the other substituents R(1), R(2), R(3) and R(4) in each case are:
• hydrogen, F, Cl, Br, I, CN, CF.sub.3, NO.sub.2, CF.sub.3 --O--, C.sub.m F.sub.2m+1 --CH.sub.2 --O-- where m=1, 2 or 3,
• R(11)--C.sub.q H.sub.2q --X.sub.p --
• where q=zero, 1, 2, 3 or 4,
• p=zero or 1,
• X=oxygen or NR(12), R(12)=H or C.sub.(1-3)-alkyl,
• R(11)=hydrogen, C.sub.1-6)-alkyl, C.sub.(3-8)-cycloalkyl, phenyl which is unsubstituted or substituted by 1, 2 or 3 substituents selected from the group consisting of F, Cl, CH.sub.3, CH.sub.3 --O--, NR(13)R(14) where R(13), R(14) is H, methyl or ethyl
• and where R(1) and R(4) are not simultaneously hydrogen.
