Abstract
Abstract Compounds of the general formulae: ##STR1## in which Ar and Ar 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.
