- R 1 and R 2 are identical or different and are C ⁇ HiR 3 - or C6H3 (OH) R 4 -, R 3 and R 4 have the meaning given above are particularly preferred for use as therapeutic active substances and wherein a substituent preferably occupies a 4- or optionally a 3-position on the phenyl ring.
- Hydroxy group is in the 4-position on the phenyl ring.
- the following compounds are particularly preferred for use as therapeutic agents:
- the symmetrically substituted compounds of the formula I in which R 1 and R 2 have the same meaning can be prepared by using the compound of the formula
- the asymmetrically substituted compounds of the formula I in which R 1 and R 2 do not have the same meaning can be prepared according to the invention by reacting the compound of the formula II simultaneously with two different reactive compounds which provide the radicals R 1 and R 2 .
- R 1 has the meaning given above, with a reactive agent which provides the radicals R 1 or R 2 .
- Both the symmetrically substituted compounds and the unsymmetrically substituted compounds of the formula I can, if desired, be converted into a pharmaceutically acceptable salt.
- the procedure is such that the 3,3'-diamine-benzidine is mixed with twice the amount of the reactive derivative in a solvent, e.g. Ethanol is reacted for several hours at the boiling point of the solvent used.
- a solvent e.g. Ethanol
- Na2S2 ⁇ s or nitrobenzene are particularly suitable as additives for the preparation of the compounds of the formula I if aldehydes are used as reactive derivatives. If acids, esters, anhydrides, alkylimides or acyl halides are used, HC1 (J. Chem. Soc, 2393-2399, [1928]), polyphosphoric acid (J. Amer.
- Unsymmetrically substituted dibenzimidazoles can be prepared in a similar manner.
- the compound 4- [2 '- (4-ethoxyphenyl) -6,6'-dibenzimidazol-2-yl] phenol is thus obtained, for example, by reacting 3,3'-diaminobenzidine with 4-hydroxybenzaldehyde and 4-ethoxy-benzaldehyde in ethanol and addition of Na2S2 ⁇ s after stirring for several hours at reflux.
- reaction solution also contains the corresponding symmetrical compounds.
- Symmetrically or asymmetrically substituted dibenzimidazole derivatives can also be obtained by using a compound of the formula with an above-mentioned reactive compound which provides the radical Rl or R 2 .
- the implementation is analogous to the process described above.
- the pharmaceutically acceptable salts can be prepared according to known
- the free bases of the formula I can be converted, for example, into the corresponding salts using the following inorganic or organic acids: hydrochloric acid, hydrobromic acid, nitric acid, sulfuric acid, phosphoric acid, citric acid, formic acid, maleic acid, acetic acid, succinic acid, tartaric acid, methanesulfonic acid, p -Toluenesulfonic acid and the like.
- Preferred salts are the hydrochlorides derived from the basic compounds of formula I, e.g. with a methanolic HC1 solution.
- the starting compounds required for the preparation of the compounds of formula I are known commercial products, e.g. the compound II, or can be easily prepared by methods known per se.
- Amino-3'-nitro-benzidine with a reactive compound which provides the radical R 1 is obtained by subsequently hydrogenating the nitro group of the isolated intermediate to give the amino group.
- the hydrogenation is carried out according to methods described in the literature, for example with
- the compound III obtained can then, as described, be reacted with a further compound which provides the radical R 1 or R 2 to give the dibenzimidazoles of the formula I.
- All reactive compounds required for the preparation of the compound I, which contain the radicals R 1 or R 2 are known compounds and / or can be prepared in an analogous manner by processes described in the literature.
- ethyl imide ester of 4-hydroxybenzoic acid can be prepared as follows:
- the minimum inhibitory concentration (MIC) of the substances examined against gram-positive and gram-negative strains was determined using standard agar methods. The compounds were dissolved in a small amount of dimethyl sulfoxide, diluted with water and incorporated in liquefied DST agar at 50 ° C. The agar plates thus produced were used in the experiment immediately afterwards. The test concentrations were between 128 and 0.06 ⁇ g ml.
- the bacterial vaccine solutions were prepared from pre-cultures incubated overnight, diluted and applied to the agar surface using an inoculation device (Denley A400). The plates were incubated at 35 ° C for 20 hours. The MIC was determined as the lowest substance concentration that prevents visible growth. A barely visible cloudiness and that
- the antibacterial activities against Helicobacter pylori were carried out analogously to the method described above, with the following changes:
- the compounds were incorporated in Müller-Hinton agar with 5% sheep blood additive.

- the compounds of the formula I and their salts are preferably suitable for parenteral administration and are preferably prepared for this purpose as lyophilisates or dry powder for dilution with conventional agents such as water or isotonic saline.
- the dosage of the compounds of general formula I and the pharmaceutically acceptable salts thereof with bases can vary within wide limits and is of course to be adapted to the individual circumstances and the pathogen to be controlled in each individual case.
- medicaments containing a compound of the general formula I or a pharmaceutically acceptable salt thereof are also a process for the preparation of such medicaments, which is characterized in that one or more compounds of the general formula I or pharmaceutically acceptable salts thereof and optionally one or more other therapeutically valuable substances in a pharmaceutical dosage form.
- Ampoules for intramuscular administration are produced in the usual way:
- a lyophilisate of 1 g of 4- [2 '- (4-hydroxyphenyl) -6,6'-dibenzimidazol-2-yl] phenol hydrochloride (1: 2) is prepared in the usual manner and
- the lyophilisate is treated with 2.5 ml of 2% lidocaine hydrochloride solution.
- Example B Tablets of the following composition are produced in the usual way: mg / tablet
- Capsules of the following composition are produced: mg / kg gel
- the active ingredient, milk sugar and corn starch are first mixed in a mixer and then in a shredder. You bring the mixture back into the mixer, add the talc and mix thoroughly. The mixture is filled into hard gelatin capsules by machine.
