| abstract |
The present invention relates to compounds of formula <IMAGE> (I) in which Q is N or CH, Ar is a radical chosen from among phenyl and optionally substituted thienyl radicals, it being possible for the substituents to be from one to three substituents: halo, lower alkyl or lower alkoxy, -AA- represents a divalent radical corresponding to an amino acid forming part of the structure of proteins, it being possible for some functional groups of this radical to be protected, or alternatively, it represents a diacyl radical, n is an integer from 0 to 4 inclusive, and X represents H, OH or Y, <IMAGE> in which when n is equal to 1, 2, 3 or 4, Y is then a hydrocarbon radical containing from 1 to 20 carbon atoms, when n is equal to 0, Y is then a hydrocarbon radical containing from 7 to 20 carbon atoms, as well as to the salts and the isomers of these compounds, to a process for the preparation of these compounds, to their application as fungicidal and/or bactericidal agents and to their compositions containing them. |
