Object of the present invention are new pharmacologically active substituted heterocyclylphenylsulphonyl and phosphonylamidines having the formula
in which Het represents a heterocyclic ring containing from 2 to 3 nitrogen atom, R represents a hydrogen atom a lower alkyl or alkoxy group containing from 1 to 3 carbon atom or a halogen atom, Y represents a group of formula -S03H or of formula
(where R" is a lower alkyl group containing from 1 to 3 carbon atom), R' represents a linear or branched alkyl group which may contain a heteroatom such as a sulfur, an oxygen or nitrogen atom, a linear or branched alkenyl group, a cycloalkyl or alkylcycloalkyl group, an aryl or an aralkyl group (optionally substituted by a lower alkyl or alkoxy group containing from 1 to 3 carbon atom or a halogen atom), tautomers thereof and acid addition salts of the aforesaid compounds.
Process for the preparation of the compounds of formula (I) as well as pharmaceutical compositions containing them are also object of this invention.
The new compounds are antisecretory-antiulcer agents.
