Particulars of the above definitions and suitable examples of these are given below: "Acyl" is a substituent which originates from an acid, such as from an organic carboxylic acid, carbonic acid, carbamic acid or the thio-acid or imide acid corresponding to the individual above acids, or from an organic sulfonic acid, these acids in each case including aliphatic, aromatic and/or heterocyclic groups in the molecule, as well as carbamoyl or carbamimidoyl.
Suitable examples of these acyl groups are given below.
Acyl radicals originating from an aliphatic acid are designated aliphatic acyl groups, these including the following: alkanoyl (e.g. formyl, acetyl, propionyl, butyryl, isobutyryl, valeryl, isovaleryl, pivaloyl etc.); alkenoyl (e.g. acryloyl, methacryloyl, crotonoyl etc.); alkylthioalkanoy! (e.g. methylthioacetyl, ethylthioacetyl etc.) alkanesulfonyl (e.g. mesyl, ethanesulfonyl, propanesulfonyl etc.); alkoxycarbonyl (e.g. methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl, isopropoxycarbonyl, butoxycarbonyl, isobutoxycarbony! etc.); alkylcarbamoyl (e.g. methylcarbamoyl etc.); (N-alkyl)-thiocarbamoyl (e.g. (N-methyl)- thiocarbamoyl etc.); alkylcarbamimidoyl (e.g. methylcarbamimidoyl etc.); oxalo; alkoxalyl (e.g. methoxalyl, ethoxalyl, propoxalyl etc.).
In the above examples of aliphatic acyl groups, the aliphatic hydrocarbon moiety, in particular the alkyl group or the alkane radical, can optionally contain one or more suitable substituents, such as amino, halogen (e.g. fluorine, chlorine, bromine etc.) hydroxyl, hydroxyimino, carboxyl, alkoxy (e.g. methoxy, ethoxy, propoxy etc.), alkoxycarbonyl, acylamino (e.g. benzyloxycarbonylamino etc.) acyloxy (e.g. acetoxy, benzoyloxy etc.) and the like; as preferred aliphatic acyl radicals with such substituents there may be mentioned e.g. alkanoyls substituted by amino, carboxyl, amino and carboxyl, halogen, acylamino or the like.
Those acyl radicals which originate from an acid with a substituted or unsubstituted aryl group are designated aromatic acyl radicals, it being possible for the aryl group to include phenyl, toluyl, xylyl, naphthyl and the like; suitable examples are given below: aroyl (e.g. benzoyl, toluoyl, xyloyl, naphthoyl, phthaloyl etc.); aralkanoy! (e.g. phenylacetyl etc.); aralkenoyl (e.g. cinnamoyl] etc.); aryloxyalkanoyl (e.g. phenoxyacetyl etc.); arylthioalkanoyl (e.g. phenylthioacetyl etc.); arylaminoalkanoyl (e.g. N-phenylglycyl, etc.); arenesulfonyl (e.g. benzenesulfonyl, tosyl or toluenesulfonyl, naphthalenesulfonyl etc.); aryloxycarbonyl (e.g. phenoxycarbonyl, naphthyl-oxycarbonyl etc.); aralkoxycarbonyl (e.g. benzyloxycarbonyl etc.); arylcarbamoyl (e.g. phenylcarbamoyl, naphthylcarbamoyl etc.); arylglyoxyloyl (e.g. phenylglyoxyloyl etc.).
In the above examples of aromatic acyl radicals, the aromatic hydrocarbon moiety (in particular the aryl radical) and/or the aliphatic hydrocarbon moiety (in particular the alkane radical) can optionally contain one or more suitable substituents, such as those which have already been mentioned as suitable substituents for the alkyl group or the alkane radical. In particular, and as an example of preferred aromatic acyl radicals with particular substituents, aroyl substituted by halogen and hydroxyl or by halogen and acyloxy and aralkanoyl substituted by hydroxyl, hydroxyimino, dihalogenoalkanoyloxyimino are mentioned, as well as arylthiocarbamoyl (e.g. phenylthiocarbamoyl etc.); arylcarbamimidoyl (e.g. phenylcarbamimidoyl etc.).
A heterocyclic acyl radical is understood as meaning an acyl radical which originates from an acid with a heterocyclic group; this includes: heterocyclic carbonyl in which the heterocyclic radical is an aromatic or aliphatic 5- to 6- membered heterocyclic radical with at least one heteroatom from the group consisting of nitrogen, oxygen and sulfur (e.g. thiophenyl, furoyl, pyrrolecarbonyl, nicotinoyl etc.); heterocyclic alkanoyl in which the heterocyclic radical is 5- to 6-membered and contains at least one heteroatom from the group consisting of nitrogen, oxygen and sulfur (e.g. thiophenyl-acetyl, furylacetyl, imidazolylpropionyl, tetrazolylacetyl, 2-(2-amino-4-thiazolyl)- 2-methoxyiminoacetyl etc.) and the like.
In the above examples of heterocyclic acyl radicals, the heterocyclic radical and/or the aliphatic hydrocarbon moiety can optionally contain one or more suitable substituents, such as the same as those which have already been mentioned as suitable substituents for alkyl and alkane groups. "Alkyl", unless defined otherwise, is a straight- or branched-chain alkyl radical having up to 26 carbon atoms, such as methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tert-butyl, pentyl, hexyl and the like. It can be substituted, e.g. by hydro-xyl, amino, halogen (e.g. fluorine, bromine, chlorine), oxo radicals and alkoxy radicals, such as methoxy, ethoxy radicals. "Alkoxy radical", unless defined otherwise, is a straight- or branched-chain alkoxy radical having up to 26 carbon atoms, such as a methoxy, ethoxy radicals [sic] etc. It can be substituted, e.g. by hydroxyl, amino, halogen, oxo groups and alkoxy radicals, such as methoxy, ethoxy radicals. Co " Alkoxy-(Co-26)-alkyl groups" are alkoxy radicals, which can also be bonded to the basic structure via an alkyl radical. The alkyl and alkoxy groups are as defined above.
3 * _ 9 _ "Cycloalkyl-(Co.26)-alkyl radicals” are cyclic compounds [sic] having 3 to 8 carbon atoms, unless defined otherwise, which are bonded to the basic structure directly or via an alkylene radical. The alkylene radical can be branched, unbranched and saturated or unsaturated with double bonds. Possible substituents of the cycloalkyl radical are, inter alia, alkoxy radicals, alkyl radicals, hydroxyl radicals, halogen radicals, amino radicals, oxo radicals. The cycloalkyl groups can also be aromatic with the corresponding number of double bonds, ie. aryl-(Cy.26)-alkyl radicals (e.g. phenyl, pyridyl, naphthyl etc.). The aromatic cyclic compounds in particular can furthermore contain substituents, such as nitro groups and CF; and phenyl radicals. "Cycloalkoxy-(Cy.26)-alkyl groups" are cyclic compounds [sic] having 3 to 8 carbon atoms which are bonded to the basic structure via an oxygen directly or via an alkylene radical. The alkylene radical can be branched, unbranched and saturated or unsaturated with double bonds.
Possible substituents of the cycloalkyl radical are, inter alia, alkoxy radicals (including alkylenedioxy radicals, such as methylenedioxy), alkyl radicals, hydroxyl radicals, halogen radicals, amino radicals, oxo radicals.

Experiments show that the action of the compounds is based on inhibition of the 1-deoxy-D- xylulose 5-phosphate (DOXP) metabolic pathway, which can be detected in bacteria, parasites and fungi but not for humans. The following example accordingly shows the action of the compounds according to the invention on DOXP reductoisomerase. oo
Example 1
DOXP reductoisomerase of Escherichia coli was expressed as a recombinant protein in E.coli.
The activity of the DOXP reductoisomerase was determined in a batch which comprised 100 mM Tris-HCI (pH = 7.5), 1 mM MnCl,, 0.3 mM NADPH and 1 mM DOXP. The -
oxidation of NADPH was measured here in a spectrophotometer at 365 nm. For carrying out the inhibition studies, the activity of the DOXP reductoisomerase in the presence of compounds 1 to 4 in various concentrations between 0.1 and 100 pmol 1-1 was measured. The concentration at which the enzyme is inhibited to half the maximum extent (ICs) was determined from the measurement values. The results, i.e. the IC50 values, are listed in the table.
Example 2
The antimalaria activity of substances 1 to 4 was determined on in vitro cultures of the malaria pathogen Plasmodium falciparum. The depressions of a 96-well microtitre plate were charged with in each case 200 pl of an asynchronous Plasmodium falciparum culture at a parasitaemia of 0.4% and haematocrit of 2%. A serial dilution series of the compounds in triple steps between concentrations of 100 to 0.14 pmol I" was then prepared. The plates were incubated at 37°C, 3% CO; and 5% O, over a period of 48 hours. 30 pl medium supplemented with 27 uCi ml” [*H]-hypoxanthine were then added to each well. After incubation for 24 hours, the parasites were harvested by filtration on a glass fibre filter and the radioactivity which had been incorporated was measured. The inhibition of the parasite growth was measured as the percentage inhibition of the incorporation of tritium. The inhibition of the parasite growth was expressed as the percentage inhibition of the incorporation of tritium based on a comparison without the substance. The half-maximum inhibitory concentration (IC50) of the substance was determined by extrapolation of the values. The results, i.e. the
IC50 values, are listed in the following table:
