Use of the above-stated substances is in particular suitable for the production of pharmaceutical preparations against bacterial diseases or for the prevention thereof or 25 for the production of herbicides. The activity of the substances is determined using a test system. This system is based upon in vitro measurement of the inhibition of growth of bacteria, parasites, viruses, fungi or plants. Test methods known to the person skilled in the art are in part used for 30 this purpose.

WO 00/16757 PCT/EP99/07054 - 15 For example, antimalarial activity is determined by measuring the inhibition of the growth of malaria parasites in blood cultures. Antibacterial activity is determined on the basis of measuring the inhibition of 5 bacterial growth on nutrient media and in liquid cultures. Antiviral activity is determined on the basis of the formation of viral elements in cell cultures. 10 Some of the microorganisms which are to be investigated may only be investigated in animal models. In this case, we will then use the appropriate models. Substances which exhibit activity in in vitro measurement systems are then further investigated in in vivo models. 15 The antiparasitic, antiviral, fungicidal or antibacterial activity is further evaluated in the appropriate animal models. Screening for herbicidal activity is determined by means of algal systems and measurement of isoprene emissions from plants under standard conditions. 20 The pharmaceutically active agents may be prepared in dosage units in the form of pharmaceutical preparations. This means that the preparation is in the form of individual components, for example tablets, coated tablets, capsules, pills, suppositories and ampoules, the active substance content of which corresponds to a 25 fraction or multiple of an individual dose. The dosage units may contain, for example 1, 2, 3 or 4 individual doses or 1/2, 1/3 or 1/4 of an individual dose. An individual dose preferably contains the quantity of active substance which is administered at one time and usually corresponds to a whole, half, third or quarter of a daily dose. 30 Non-toxic, inert, pharmaceutically suitable excipients should be taken to mean solid, semi-solid or liquid diluents, fillers and formulation auxiliaries of all kinds.
