ABSTRACT:
FIELD OF THE INVENTION
The invention relates to compounds intended for use in the pharmaceutical industry as active principles for preparing medicaments.
STATE OF THE ART
International patent application WO 96/16656 describes compounds of a general formula A-X—R in which A may be a fused imidazolyl radical and R may be a nonaromatic hydrocarbon radical. European patent application EP 632040 describes further fused imidazoles which carry as substituent B a 5- or 6-membered fused or nonfused unsubstituted heterocycle. International patent application WO 98/28299 describes imidazopyridazines attached via a specific bridge in position 4 to a pyridine ring substituted in position 2. International patent application WO 99/61439 describes pyridylmethyl-aminopyrimidines substituted. In a special way in position 4. International patent applications WO 01/34573 and WO 01/34578 disclose compounds comprising primarily, on the one hand, S-substituted thiophenols with a benzimidazol-2-yl-thiomethyl radical in position 3 and, on the other hand, S- or O-substituted thiophenols and pyridinethiols or phenols and pyridinols, respectively, with an N-heterocyclylmethyl radical in position 3. All of the compounds specified in the above documents are said to be suitable for controlling Helicobacter bacteria.
