Compounds of the general formula: ##STR1## and acid addition salts thereof; in which Ar and Ar.sup.1 which may be the same or different, each represent an aromatic radical which may be substituted one or more times by substituents selected from the following:

Imidazole derivatives and pharmaceutical compositions

Compounds of the general formula: ##STR1## and acid addition salts thereof; in which

Imidazole derivatives used in antithrombotic method

Compounds of the general formulae: ##STR1## in which Ar and Ar.sup.1 which may be the same or different represent aromatic radicals optionally substituted once or more than by substituents selected from halogen, lower alkyl and lower alkoxy and Alk represents an alkylene group containing from 1 to 4 carbon atoms which alkylene group may be interrupted with a heteroatom; and acid addition salts thereof. These compounds have anti-anaerobe and also anti-fungal activity and are non-mutagenic.

Imidazole hydrazone and hydrazine derivatives

Compounds corresponding to the following general formula: ##STR1## wherein Ar and Ar.sup.1, which may be the same or different, each represents an aromatic radical which may be substituted one or more times by halogen and/or nitro and/or lower alkyl and/or trihalomethyl and/or cyano and/or lower alkoxy and/or di-lower alkyl-amino, the alkyl groups optionally completing a ring optionally incorporating a further heteroatom, and/or lower alkyl sulphonyl;
