| abstract |
The invention relates to organo-phosphorus compounds of formula (I), wherein A is selected from the group consisting of a (C1-9) alkylene radical, -C-O-C- and -C-N-C- or A corresponds to formula (II), wherein one or more carbon atoms selected from the group consisting of C3, C4, C5 and their substituents can also be absent and at least one of the substituents of B1 to B10 is a C3-8-cycloalkyl-(C0-9)-alkyl group in which R1 is selected from the group consisting of five and six membered heterocycles having at least one nitrogen atom in the ring or polycyclic carbon atoms containing one of said heterocycles, wherein at least one of said nitrogen atoms belongs to a hydroxamic acid group or a hydroxamic acid ester group. The invention also relates to the utilization of the above-mentioned compounds in the therapeutic and prophylactic treatment of infections in human beings and animals caused by virus, bacteria, fungi and parasites and as fungicides, bactericides and herbicides in plants. |
