In many cases, in particular at low application rates, the fungicidal action of the known compounds is unsatisfactory. Accordingly, it is an object of the present invention to provide compounds having improved action and/or a broader activity spectrum.

Accordingly, we have found the compounds defined at the outset. Furthermore, we have found processes and intermediates for their preparation, compositions comprising them and also methods for controlling harmful fungi using the compounds I.

The compounds of the formula I according to the invention can be obtained by different routes.

Pyridazines of the formula I in which both groups R¹and R⁴are halogen, in particular chlorine, are advantageously accessible by halogenation of the compounds of the formula II with a halogenating agent [HAL] by the route below. They correspond to the formula I.1, in which Hal is halogen, preferably bromine or chlorine, in particular chlorine.

This reaction is usually carried out at temperatures of from 0 to 150° C. or preferably from 80 to 125° C., in the absence of a solvent or in an inert organic solvent [cf.

Preferred halogenating agents are chlorinating or brominating agents, such as phosphorus oxybromide, phosphorus oxychloride, thionyl chloride, thionyl bromide or sulfuryl chloride, in particular phosphorus oxychloride. The reaction can be carried out in the absence of a solvent or in the presence of a solvent.

Some of the intermediates and end products are obtained in the form of colorless or slightly brownish viscous oils which are purified or freed from volatile components under reduced pressure and at moderately elevated temperature. If the intermediates and end products are obtained as solids, purification can also be carried out by recrystallization or digestion.

If individual compounds of the formula I can not be obtained by the routes described above, they can be prepared by derivatization of other compounds I.

If the synthesis yields mixtures of isomers, a separation is generally not necessarily required since in some cases the individual isomers can be interconverted during preparation for application or during application (for example under the action of light, acid or bases). Such conversions may also take place after application, for example in the case of the treatment of plants in the treated plants or in the harmful fungus to be controlled.

Amounts typically applied in the protection of materials are, for example, from 0.001 g to 2 kg, preferably from 0.005 g to 1 kg, of active compound per cubic meter of treated material.

The compounds of the formula I can be present in different crystal modifications which may differ in their biological activity. They are likewise subject matter of the present invention.

The compounds I can be converted into the customary formulations, for example solutions, emulsions, suspensions, dusts, powders, pastes or granules. The use form depends on the particular intended purpose; in each case, it should ensure a fine and even distribution of the compound according to the invention.

The formulations are prepared in a known manner, for example by extending the active compounds with solvents and carriers or solvents or carriers, if desired using further auxiliaries such as emulsifiers and dispersants.

K ULV Solutions (UL)

10 parts by weight of the active compounds are dissolved in 90 parts by weight of an organic solvent, for example xylene. This gives a product to be applied undiluted having an active compound content of 10% by weight.

For seed treatment, use is usually made of water-soluble concentrates (LS), suspensions (FS), dustable powders (DS), water-dispersible and water-soluble powders (WS, SS), emulsions (ES), emulsifiable concentrates (EC) and gel formulations (GF). These formulations can be applied to the seed in undiluted form or, preferably, diluted. Application can be carried out prior to sowing.

The use forms depend entirely on the intended purposes; they should always ensure the finest possible distribution of the active compounds according to the invention.

Aqueous use forms can be prepared from emulsifiable concentrates, pastes or wettable powders (spray powders, oil dispersions) by addition of water. To prepare emulsions, pastes or oil dispersions, the substances can be homogenized in water, as such or dissolved in an oil or solvent, by means of wetting agents, tackifiers, dispersants or emulsifiers. However, it is also possible to prepare concentrates comprising active substance, wetting agent, tackifier, dispersant or emulsifier and possibly solvent or oil which are suitable for dilution with water.

The concentrations of active compound in the ready-for-use preparations can be varied within relatively wide ranges. In general, they are between 0.0001 and 10%, preferably between 0.01 and 1%.

The active compounds can also be used with great success in the ultra-low volume (ULV) process, it being possible to apply formulations with more than 95% by weight of active compound or even the active compound without additives.

Oils of various types, wetting agents, adjuvants, herbicides, fungicides, other pesticides and bactericides can be added to the active compounds, if appropriate also not until immediately before use (tank mix). These agents can be added to the compositions according to the invention in a weight ratio of 1:100 to 100:1, preferably of 1:10 to 10:1.

The following are particularly suitable as adjuvants in this context: organically modified polysiloxanes, for example Break Thru S 240®; alcohol alkoxylates, for example Atplus 245®, Atplus MBA 1303®, Plurafac LF 300® and Lutensol ON 30®; EO-PO block polymers, for example Pluronic RPE 2035® and Genapol B®; alcohol ethoxylates, for example Lutensol XP 80®; and sodium dioctylsulfosuccinate, for example Leophen RA®.

The compositions according to the invention in the application form as fungicides can also be present together with other active compounds, for example with herbicides, insecticides, growth regulators, fungicides or else with fertilizers. When mixing the compounds (I) or the compositions comprising them with one or more further active compounds, in particular fungicides, it is in many cases possible, for example, to widen the activity spectrum or to prevent the development of resistance.

The pyridazines of the formula I according to the invention, in particular the pyridazines of the formula I according to the invention described in the above description as being preferred, and/or their pharmaceutically acceptable salts are suitable for the treatment, inhibiton or control of growth and/or propagation of tumor cells and the disorders associated therewith. Accordingly, they are suitable for cancer therapy in warm-blooded vertebrates, for example mammals and birds, in particular man, but also other mammals, in particular useful and domestic animals, such as dogs, cats, pigs, ruminants (cattle, sheep, goats, bison, etc.), horses and birds, such as chicken, turkey, ducks, geese, guineafowl and the like.

The pyridazines of the formula I according to the invention, especially the pyridazines of the formula I according to the invention described in the above description as being preferred, and/or their pharmaceutically acceptable salts are particularly suitable for the therapy of cancer or cancerous disorders of the following organs: breast, lung, intestine, prostate, skin (melanoma), kidney, bladder, mouth, larynx, esophagus, stomach, ovaries, pancreas, liver and brain.

In addition to the pyridazine I according to the invention and/or its pharmaceutically acceptable salt, the pharmaceutical compositions according to the invention comprise at least optionally a suitable carrier. Suitable carriers are, for example, the solvents, carriers, excipients, binders and the like customarily used for pharmaceutical formulations, which are described below in an exemplary manner for individual types of administration.

The compounds I according to the invention can be administered in a customary manner, for example orally, intravenously, intramuscularly or subcutaneously. For oral administration, the active compound can be mixed, for example, with an inert diluent or with an edible carrier; it can be embedded into a hard or soft gelatin capsule, it can be compressed to tablets or it can be mixed directly with the food/feed. The active compound can be mixed with excipients and administered in the form of indigestible tablets, buccal tablets, pastilles, pills, capsules, suspensions, potions, syrups and the like. Such preparations should contain at least 0.1% of active compound. The composition of the preparation may, of course, vary. It usually comprises from 2 to 60% by weight of active compound, based on the total weight of the preparation in question (dosage unit). Preferred preparations of the compound I according to the invention comprise from 10 to 1000 mg of active compound per oral dosage unit.

The tablets, pastilles, pills, capsules and the like may furthermore comprise the following components: binders, such as traganth, gum arabic, corn starch or gelatin, excipients, such as dicalcium phosphate, disintegrants, such as corn starch, potato starch, alginic acid and the like, glidants, such as magnesium stearate, sweeteners, such as sucrose, lactose or saccharin, and/or flavors, such as peppermint, vanilla and the like. The capsules may furthermore comprise a liquid carrier. Other substances which modify the properties of the dosage unit may also be used. For example, tablets, pills and capsules may be coated with shellac, sugar or mixtures thereof. In addition to the active compound, syrups or potions may also comprise sugar (or other sweeteners), methyl- or propylparaben as preservative, a colorant and/or a flavor. The components of the active compound preparations must, of course, be pharmaceutically pure and nontoxic at the quantities employed. Furthermore, the active compounds can be formulated as preparations with a controlled release of active compound, for example as delayed-release preparations.

The active compounds can also be administered parenterally or intraperitoneally. Solutions or suspensions of the active compounds or their salts can be prepared with water using suitable wetting agents, such as hydroxypropylcellulose. Dispersions can also be prepared using glycerol, liquid polyethylene glycols and mixtures thereof in oils. Frequently, these preparations furthermore comprise a preservative to prevent the growth of microorganisms.

Preparations intended for injections comprise sterile aqueous solutions and dispersions and also sterile powders for preparing sterile solutions and dispersions. The preparation has to be sufficiently liquid for injection. It has to be stable under the preparation and storage conditions and it has to be protected against contamination by microorganisms. The carrier may be a solvent or a dispersion medium, for example, water, ethanol, a polyol (for example glycerol, propylene glycol or liquid polyethylene glycol), a mixture thereof and/or a vegetable oil.

SYNTHESIS EXAMPLES

With appropriate modification of the starting materials, the procedures given in the synthesis examples below were used to obtain further compounds I. The compounds produced in this manner are listed in the table below, together with physical data.

The HPLC retention times (RT) in the following examples were determined using the RP-18 column Chromolith Speed ROD (Merck KgaA, Germany), with the eluent acetonitrile+0.1% trifluoroacetic acid (TFA)/water+0.1% TFA in a gradient of from 5:95 to 95:5 in 5 minutes at 40° C. Mass spectrometry was effected using quadropole electrospray ionization, 80 V (positive mode)

Example 1
Preparation of (3-{-4-[3-chloro-5-(4-chlorophenyl)-6-methylpyridazin-4-yl]-3,5-difluorophenoxy}propyl)dimethylamine [I-1]
Step 1: 4-[3-Chloro-5-(4-chlorophenyl)-6-methylpyridazin-4-yl)-3,5-difluorophenol

0.2 g of 3-chloro-5-(4-chlorophenyl)-4-(2,6-difluoro-4-methoxyphenyl)-6-methylpyridazine (cf. WO 2005/121104) and 1 ml of 1M BBr₃solution in methylene chloride were stirred at 20 to 25° C. for about 6 hours. The reaction mixture was then hydrolyzed with water, and the aqueous phase was extracted with ethyl acetate. The combined organic phases were dried and freed from the solvent. This gave 0.2 g of the title compound as a lightly colored crystalline material.

¹H-NMR (CDCl₃, δ in ppm): 7.35 (d, 2H); 7.1 (s, br, 1H); 7.05 (d, 2H); 6.4 (d, 2H); 2.55 (s, 3H)

Step 2: (3-{-4-[3-Chloro-5-(4-chlorophenyl)-6-methylpyridazin-4-yl]-3,5-difluorophenoxy}propyl)dimethylamine

0.2 g of diethyl azodicarboxylate was added to 0.2 g of 4-[3-chloro-5-(4-chlorophenyl)-6-methylpyridazin-4-yl)-3,5-difluorophenol (from step 1), 0.1 g of dimethylaminopropanol and 0.3 g of triphenylphosphine in 5 ml of tetrahydrofuran, and the mixture was stirred at from 20 to 25° C. for about 1 hour. The reaction mixture was concentrated and the residue was purified by MPLC on silica gel using cyclohexane/ethyl acetate mixtures. The residue obtained after concentration of the eluate crystallized and was digested with hexane/diisopropyl ether. This gave 0.13 g of the title compound as a colorless crystalline material of m.p. 112-113° C.

¹H-NMR (CDCl₃, δ in ppm): 7.3 (d, 2H); 7.0 (d, 2H); 6.4 (d, 2H); 3.95 (t, 2H); 2.55 (s, 3H); 2.4 (t, 2H); 2.25 (s, 6H); 1.9 (m, 2H)

Examples of the Action Against Harmful Fungi

The fungicidal action of the compounds of the formula I was demonstrated by the following experiments:

The active compounds were prepared as a stock solution comprising 25 mg of active compound which was made up to 10 ml using a mixture of acetone and/or DMSO and the emulsifier Uniperol® EL (wetting agent having emulsifying and dispersing action based on ethoxylated alkylphenols) in a volume ratio of solvent/emulsifier of 99/1. The mixture was then made up to 100 ml with water. This stock solution was diluted with the solvent/emulsifier/water mixture described to the concentration of active compounds stated below. Alternatively, the active compounds were used as a commercial finished formulation and diluted with water to the stated active compound concentration.

Use Example 1
Activity Against Late Blight on Tomatoes Caused by Phytophthora infestans, Protective Treatment

Leaves of potted tomato plants were sprayed to runoff point with an aqueous suspension having the active compound concentration stated below. The next day, the leaves were infected with an aqueous sporangia suspension of Phytophthora infestans. The plants were then placed in a water vapor-saturated chamber at temperatures between 18 and 20° C. After 6 days, the late blight on the untreated but infected control plants had developed to such an extent that the infection could be determined visually in %.

In this test, the plants treated with 250 ppm of the active compound I-1 showed no infection, whereas the untreated plants were 80% infected.

Use Example 2
Protective Activity Against Septoria Leaf Blotch of Wheat Caused by Septoria tritici

Leaves of potted wheat seedlings were inoculated with a spore suspension of the leaf blotch disease Septoria tritici. The test plants were then placed in a greenhouse at temperatures between 20 and 22° C. and a relative atmospheric humidity of close to 100% and then at temperatures between 16 and 18° C. and an atmospheric humidity of about 70% for 4 days. Six days after the inoculation, the plants were sprayed to runoff point with an aqueous active compound solution having the concentration stated below. After the spray coating had dried on, the plants were returned. After 14 days, the extent of the development of the disease was determined visually in % infection of the entire leaf area.

In this test, the plants which had been treated with 250 ppm of the active compound I-1 showed an infection of 10%, whereas the untreated plants were 90% infected. The active compounds were formulated separately as a stock solution having a concentration of 10 000 ppm in DMSO.

Use Example 3
Activity Against the Septoria Leaf Blotch Pathogen Septoria tritici the Microtiter Test

The stock solution is pipetted into a microtiter plate (MTP) and diluted with an aqueous malt-based fungus nutrient medium to the stated active compound concentration. An aqueous spore suspension of Septoria tritici was then added. The plates were placed in a water vapor-saturated chamber at temperatures of 18° C. Using an absorption photometer, the MTPs were measured at 405 nm on day 7 after the inoculation.

The measured parameters were compared to the growth of the active compound-free control variant (100%) and the fungus- and active compound-free blank value to determine the relative growth in % of the pathogens in the individual active compounds.

Use Example 4
Activity Against the Gray Mold Pathogen Botrytis cinerea in the Microtiter Test

The stock solution is pipetted into a microtiter plate (Mtp) and diluted with an aqueous malt-based fungus nutrient medium to the stated active compound concentration. An aqueous spore suspension of Botrytis cinerea was then added. The plates were placed in a water vapor-saturated chamber at temperatures of 18° C. Using an absorption photometer, the MTPs were measured at 405 nm on day 7 after the inoculation.

The measured parameters were compared to the growth of the active compound-free control variant and the fungus- and active compound-free blank value to determine the relative growth in % of the pathogens in the individual active compounds.
