FIELD OF THE INVENTION
The present invention relates to novel and inventive parasiticidal and pesticidal isoxazoline compounds of formula (I):




wherein, D1, D2, D3, D4, D5, B1, B2, B3, R1, R2, R3, R4, R5, R6, Y, Z, L, a and b are as defined below, and compositions comprising at least one compound of formula (I) in combination with a pharmaceutically acceptable or agriculturally acceptable carrier. The invention also relates to uses of the compounds and methods comprising the compounds for the treatment and prevention of parasitic infections or infestations and for controlling pests in crops, plants, plant propagation material and material derived from wood.

BACKGROUND OF THE INVENTION
Animals such as mammals and birds are often susceptible to parasite infestations/infections. These parasites may be ectoparasites, such as insects, and endoparasites such as nematodes and other worms. Domesticated animals, such as cats and dogs, are often infested with one or more of the following ectoparasites:
fleas (e.g. Ctenocephalides spp., such as Ctenocephalides felis and the like);
ticks (e.g. Rhipicephalus spp., Ixodes spp., Dermacentor spp., Amblyoma spp., and the like);
mites (e.g. Demodex spp., Sarcoptes spp., Otodectes spp., and the like);
lice (e.g. Trichodectes spp., Cheyletiella spp., Linognathus spp. and the like);
mosquitoes (Aedes spp., Culex spp., Anopheles spp. and the like); and
flies (Hematobia spp., Musca spp., Stomoxys spp., Dermatobia spp., Cochliomyia spp. and the like).
Fleas are a particular problem because not only do they adversely affect the health of the animal or human, but they also cause a great deal of psychological stress. Moreover, fleas may also transmit pathogenic agents to animals and humans, such as tapeworm (Dipylidium caninum).
Similarly, ticks are also harmful to the physical and psychological health of the animal or human. However, the most serious problem associated with ticks is that they are vectors of pathogenic agents in both humans and animals. Major diseases which may be transmitted by ticks include borrelioses (Lyme disease caused by Borrelia burgdorferi), babesiosis (or piroplasmoses caused by Babesia spp.) and rickettsioses (e.g. Rocky Mountain spotted fever). Ticks also release toxins which cause inflammation or paralysis in the host. Occasionally, these toxins are fatal to the host.
Likewise, farm animals are also susceptible to parasite infestations. For example, a parasite which is prevalent among cattle in some regions are ticks of the genus Rhipicephalus, especially those of the species microplus (cattle tick), decoloratus and annulatus. Ticks such as Rhipicephalus microplus (formerly Boophilus microplus) are difficult to control because they lay eggs in the pasture where farm animals graze. This species of ticks is considered a one-host tick and spends immature and adult stages on one animal before the female engorges and falls off the host to lay eggs in the environment. The life cycle of the tick is approximately three to four weeks. In addition to cattle, Rhipicephalus microplus may infest buffalo, horses, donkeys, goats, sheep, deer, pigs, and dogs. A heavy tick burden on animals can decrease production and damage hides as well as transmit diseases such as babesiosis (“cattle fever”) and anaplasmosis.
Animals and humans also suffer from endoparasitic infections including, for example, helminthiasis which is caused by of parasitic worms categorized as cestodes (tapeworm), nematodes (roundworm) and trematodes (flatworm or flukes). These parasites adversely affect the nutrition of the animal and cause severe economic losses in pigs, sheep, horses, and cattle as well as affecting companion animals and poultry. Other parasites which occur in the gastrointestinal tract of animals and humans include Ancylostoma, Necator, Ascaris, Strongyloides, Trichinella, Capillaria, Toxocara, Toxascaris, Trichiris, Enterobius and parasites which are found in the blood or other tissues and organs such as filarial worms and the extra intestinal stages of Strogyloides, Toxocara and Trichinella. Various patent publications have described isoxazoline derivatives having pesticidal properties, compositions comprising these compounds and use of the compounds in the fields of agriculture and veterinary medicine.

Stereoisomers and Polymorphic Forms

It will be appreciated by those of skill in the art that the compounds of the invention may exist and be isolated as optically active and racemic forms. Compounds having one or more chiral centers, including that at a sulfur atom, may be present as single enantiomers or diastereomers or as mixtures of enantiomers and/or diastereomers. For example, it is well known in the art that sulfoxide compounds may be optically active and may exist as single enantiomers or racemic mixtures. In addition, compounds of the invention may include one or more chiral centers, which results in a theoretical number of optically active isomers. Where compounds of the invention include n chiral centers, the compounds may comprise up to 2n optical isomers. The present invention encompasses the specific enantiomers or diastereomers of each compound as well as mixtures of different enantiomers and/or diastereomers of the compounds of the invention that possess the useful properties described herein. The optically active forms can be prepared by, for example, resolution of the racemic forms by selective crystallization techniques, by synthesis from optically active precursors, by chiral synthesis, by chromatographic separation using a chiral stationary phase or by enzymatic resolution.
The compounds of present invention may also be present in different solid forms such as different crystalline forms or in the form of an amorphous solid. The present invention encompasses different crystalline forms as well as amorphous forms of the inventive compounds.
In addition, the compounds of the invention may exist as hydrates or solvates, in which a certain stoichiometric amount of water or a solvent is associated with the molecule in the crystalline form. The hydrates and solvates of the compounds of formula (I), (IA), (IB), (IC), (ID) and (IE) are also the subject of the invention.
Salts
In addition to the neutral compounds of formula (I), salt forms of the compounds are also active against animal pests. The terms “veterinarily acceptable salt” and “agriculturally acceptable salt” are used throughout the specification to describe any salts of the compounds that are acceptable for administration for veterinary and agricultural applications, and which provides the active compound upon administration.
In cases where compounds are sufficiently basic or acidic to form stable non-toxic acid or base salts, the compounds may be in the form of a veterinarily or agriculturally acceptable salt. Veterinarily or agriculturally acceptable salts include those derived from veterinarily or agriculturally acceptable inorganic or organic bases and acids. Suitable salts include those comprising alkali metals such as lithium, sodium or potassium, alkaline earth metals such as calcium, magnesium and barium. Salts comprising transition metals including, but not limited to, manganese, copper, zinc and iron are also suitable. In addition, salts comprising ammonium cations (NH4+) as well as substituted ammonium cations, in which one or more of the hydrogen atoms are replaced by alkyl or aryl groups are encompassed by the invention.
Salts derived from inorganic acids including, but not limited to, hydrohalide acids (HCl, HBr, HF, HI), sulfuric acid, nitric acid, phosphoric acid, and the like are particularly suitable. Suitable inorganic salts also include, but not limited to, bicarbonate, and carbonate salts. In some embodiments, examples of veterinarily and agriculturally acceptable salts are organic acid addition salts formed with organic acids including, but not limited to, maleate, dimaleate, fumarate, tosylate, methanesulfonate, acetate, citrate, malonate, tartarate, succinate, benzoate, ascorbate, α-ketoglutarate, and α-glycerophosphate. Of course, other acceptable organic acids may be used.
Alkali metal (for example, sodium, potassium or lithium) or alkaline earth metal (for example calcium) salts of the compounds can also be made by reacting a sufficiently acidic residue on the compounds with a hydroxide of the alkali metal or alkaline earth metal.
Veterinarily and agriculturally acceptable salts may be obtained using standard procedures well known in the art, for example by reacting a sufficiently basic compound such as an amine with a suitably acid functional group present in the compound, or by reacting a suitable acid with a suitably basic functional group on the compound of the invention.

Synthesis of Compounds
The isoxazoline compounds of formula (I), (IA), (IB), (IC), (ID) or (IE) may be prepared by processes described herein or by adaptation of these processes or process known in the art to prepare compounds with different substitution patterns. For example, the compounds of the invention may be prepared by adaptation of processes described in U.S. Pat. Nos. 7,951,828; 7,662,971; 7,662,972; 8,389,738; 8,217,180; 8,513,431 and U.S. Patent Publication No. 2010/0137612 (all incorporated herein by reference). Scheme 1 below describes one embodiment of the synthesis of certain compounds of the invention of formula (I), wherein A1, A2, A3, R1, B1, B2, B3, R2, R3, R4, R5, R6, R8 L, Y, a and b are as described above, from carboxylic acid 1-1.




The preparation of carboxylic acid 1-1 has been described previously in, for example, U.S. Pat. Nos. 7,951,828; 7,662,971; 7,662,972; 8,389,738; 8,217,180; 8,513,431 and U.S. Patent Publication No. 2010/0137612. Thus, carboxylic acid 1-1 is activated by addition of an appropriate activating agent such as a known peptide coupling agent including, but not limited to, a carbodiimide coupling agent, a phosphonium or uronium coupling agents and the like, to generate an activated acyl group, followed by reaction with compound 1-2 to provide the desired compound 1-3. A general description of this transformation is described in March's Advanced Organic Chemistry—Reactions, Mechanisms and Structure (6th Edition), ed. Michael B. Smith and Jerry March, Wiley Interscience (John Wiley & Sons, Inc.), page 1430-1434 (16-74—Acylation of Amines by Carboxylic Acids—Amino-de-hydroxylation), (2007). In another embodiment, the carboxylic acid 1-1 may be first converted to a reactive acyl halide compound or activated ester compound that is then reacted with compound 1-2 to form compound 1-3. Activated ester compounds include esters of phenols containing one or more electronic withdrawing groups on the phenyl ring such nitro, fluoro, chloro, and the like. Other active esters include succinimido esters (see for example, Amino Acid and Peptide Synthesis, second edition, by John Jones; Oxford University Press, 2002).
In another embodiment of the invention, certain compounds of the invention of formula (I), wherein A1, A2, A3, R1, B1, B2, B3, R2, R3, R4, R5, R6, R8, L, Y, a and b are as described above, are prepared from carboxylic acid 1-1 according to the method shown in scheme 2 below.




In the embodiment shown in scheme 2, the carboxylic acid 1-1 is reacted with an unprotected (P=H) or nitrogen-protected compound 2-2 in the presence of a coupling agent. If compound 2-2 is protected with a nitrogen protecting group, the protecting group is removed to form compound 2-3. Compound 2-3 is then reacted with the group LG-Y to form the desired compound. Alternatively, the carboxylic acid 1-1 is first converted to an acyl halide or active ester and then reacted with compound 2-2 to form compound 2-3, which is then reacted further to form compound 1-3.
The invention further contemplates separating the enantiomers in whole or in part of the present invention or synthesizing enantiomerically enriched compounds of the invention. The composition may be prepared by separating the enantiomers in whole or in part by standard methods, for example by chemical resolution using optically active acid or by use of column chromatography or reverse-phase column chromatography using a substantially optically active (or “chiral”) stationary phase as known to those skilled in the art. The formation and/or isolation of specific enantiomers of a compound is not routine, and there are no general methods that may be used to obtain specific enantiomers of all compounds. The methods and conditions used to obtain specific enantiomers of a compound must be determined for each specific compound. Enantiomerically enriched compounds of the invention can also be obtained from enantiomerically enriched precursors.
Veterinary Compositions
Another aspect of the invention is the formation of parasiticidal compositions which comprise the isoxazoline compounds of the invention. The composition of the invention can also be in a variety of forms which include, but are not limited to, oral formulations, injectable formulations, and topical, dermal or subdermal formulations. The formulations are intended to be administered to an animal which includes but is not limited to mammals, birds and fish. Examples of mammals include but are not limited to humans, cattle, sheep, goats, llamas, alpacas, pigs, horses, donkeys, dogs, cats and other livestock or domestic mammals. Examples of birds include turkeys, chickens, ostriches and other livestock or domestic birds.
The composition of the invention may be in a form suitable for oral use, for example, as baits (see, e.g., U.S. Pat. No. 4,564,631, incorporated herein by reference), dietary supplements, troches, lozenges, chewables, tablets, hard or soft capsules, emulsions, aqueous or oily suspensions, aqueous or oily solutions, oral drench formulations, dispersible powders or granules, premixes, syrups or elixirs, enteric formulations or pastes. Compositions intended for oral use may be prepared according to any method known in the art for the manufacture of pharmaceutical compositions and such compositions may contain one or more agents selected from the group consisting of sweetening agents, bittering agents, flavoring agents, coloring agents and preserving agents in order to provide pharmaceutically elegant and palatable preparations.
Tablets or chewable dosage forms may contain the active ingredient in admixture with non-toxic, pharmaceutically acceptable excipients which are suitable for the manufacture of tablets. These excipients may be, for example, inert diluents, such as calcium carbonate, sodium carbonate, lactose, calcium phosphate or sodium phosphate; granulating and disintegrating agents, for example, corn starch, or alginic acid; binding agents, for example starch, gelatin or acacia, and lubricating agents, for example, magnesium stearate, stearic acid or talc, the tablets may be uncoated or they may be coated by known techniques to delay disintegration and absorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a time delay material such as glyceryl monostearate or glyceryl distearate may be employed. They may also be coated by the technique described in U.S. Pat. Nos. 4,256,108; 4,166,452; and 4,265,874 (incorporated herein by reference) to form osmotic therapeutic tablets for controlled release.
Formulations for oral use may be hard gelatin capsules, wherein the active ingredient is mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin. Capsules may also be soft gelatin capsules, wherein the active ingredient is mixed with water or miscible solvents such as propylene glycol, polyethylene glycols (PEGs) and ethanol, or an oil medium, for example peanut oil, liquid paraffin, or olive oil.
The compositions of the invention may also be in the form of oil-in-water or water-in-oil emulsions. The oily phase may be a vegetable oil, for example, olive oil or arachis oil, or a mineral oil, for example, liquid paraffin or mixtures of these. Suitable emulsifying agents may be naturally-occurring phosphatides, for example, soybean, lecithin, and esters or partial esters derived from fatty acids and hexitol anhydrides, for example, sorbitan monoleate, and condensation products of the said partial esters with ethylene oxide, for example, polyoxyethylene sorbitan monooleate. The emulsions may also contain sweetening agents, bittering agents, flavoring agents, and/or preservatives.
In one embodiment of the formulation, the composition of the invention is in the form of a microemulsion. Microemulsions are well suited as the liquid carrier vehicle. Microemulsions are quaternary systems comprising an aqueous phase, an oily phase, a surfactant and a cosurfactant. They are translucent and isotropic liquids.
Microemulsions are composed of stable dispersions of microdroplets of the aqueous phase in the oily phase or conversely of microdroplets of the oily phase in the aqueous phase. The size of these microdroplets is less than 200 nm (1000 to 100,000 nm for emulsions). The interfacial film is composed of an alternation of surface-active (SA) and co-surface-active (Co-SA) molecules which, by lowering the interfacial tension, allows the microemulsion to be formed spontaneously.
In one embodiment of the oily phase, the oily phase can be formed from mineral or vegetable oils, from unsaturated polyglycosylated glycerides or from triglycerides, or alternatively from mixtures of such compounds. In one embodiment of the oily phase, the oily phase comprises of triglycerides; in another embodiment of the oily phase, the triglycerides are medium-chain triglycerides, for example C8-C10 caprylic/capric triglyceride. In another embodiment of the oily phase will represent a % v/v range selected from the group consisting of about 2 to about 15%; about 7 to about 10%; and about 8 to about 9% v/v of the microemulsion.
The aqueous phase includes, for example water or glycol derivatives, such as propylene glycol, glycol ethers, polyethylene glycols or glycerol. In one embodiment of the glycol derivatives, the glycol is selected from the group consisting of propylene glycol, diethylene glycol monoethyl ether, dipropylene glycol monoethyl ether and mixtures thereof. Generally, the aqueous phase will represent a proportion from about 1 to about 4% v/v in the microemulsion.
Surfactants for the microemulsion include diethylene glycol monoethyl ether, dipropyelene glycol monomethyl ether, polyglycolyzed C8-C10 glycerides or polyglyceryl-6 dioleate. In addition to these surfactants, the cosurfactants include short-chain alcohols, such as ethanol and propanol.
Some compounds are common to the three components discussed above, i.e., aqueous phase, surfactant and cosurfactant. However, it is well within the skill level of the practitioner to use different compounds for each component of the same formulation. In one embodiment for the amount of surfactant/cosurfactant, the cosurfactant to surfactant ratio will be from about 1/7 to about 1/2. In another embodiment for the amount of cosurfactant, there will be from about 25 to about 75% v/v of surfactant and from about 10 to about 55% v/v of cosurfactant in the microemulsion.
Oily suspensions may be formulated by suspending the active ingredient in a vegetable oil, for example, atachis oil, olive oil, sesame oil or coconut oil, or in mineral oil such as liquid paraffin. The oily suspensions may contain a thickening agent, for example, beeswax, hard paraffin or cetyl alcohol. Sweetening agents such as sucrose, saccharin or aspartame, bittering agents, and flavoring agents may be added to provide a palatable oral preparation. These compositions may be preserved by the addition of an anti-oxidant such as ascorbic acid, or other known preservatives.
Aqueous suspensions may contain the active material in admixture with excipients suitable for the manufacture of aqueous suspensions. Such excipients are suspending agents, for example, sodium carboxymethylcellulose, methylcellulose, hydroxy-propylmethylcellulose, sodium alginate, polvinylpyrrolidone, gum tragacanth and gum acacia; dispersing or wetting agents may be a naturally-occurring phosphatide, for example lecithin, or condensation products of an alkylene oxide with fatty acids, for example polyoxyethylene stearate, or condensation products of ethylene oxide with long chain aliphatic alcohols, for example, heptadecaethyleneoxycetanol, or condensation products of ethylene oxide with partial esters derived from fatty acids and a hexitol such as polyoxyethylene sorbitol monooleate, or condensation products of ethylene oxide, with partial esters derived from fatty acids and hexitol anhydrides, for example polyethylene sorbitan monooleate. The aqueous suspensions may also contain one or more preservatives, for example ethyl, or n-propyl, p-hydroxybenzoate, one or more coloring agents, one or more flavoring agents, and one or more sweetening agents and/or bittering agents, such as those set forth above.
Dispersible powders and granules suitable for preparation of an aqueous suspension by the addition of water provide the active ingredient in admixture with a dispersing or wetting agent, suspending agent and one or more preservatives. Suitable dispersing or wetting agents and suspending agents are exemplified by those already mentioned above. Additional excipients, for example, sweetening, bittering, flavoring and coloring agents, may also be present.
Syrups and elixirs may be formulated with sweetening agents, for example, glycerol, propylene glycol, sorbitol or sucrose. Such formulations may also contain a demulcent, a preservative, flavoring agent(s) and/or coloring agent(s).
In another embodiment of the invention, the composition can be in paste form. Examples of embodiments in a paste form include but are not limited to those described in U.S. Pat. Nos. 6,787,342 and 7,001,889 (each of which are incorporated herein by reference). In addition to the isoxazoline compound of the invention, the paste can also contain fumed silica; a viscosity modifier; a carrier; optionally, an absorbent; and optionally, a colorant, stabilizer, surfactant, or preservative.
The process for preparing a paste formulation comprises the steps of:
(a) dissolving or dispersing the isoxazoline compound into the carrier by mixing;
(b) adding the fumed silica to the carrier containing the dissolved isoxazoline compound and mixing until the silica is dispersed in the carrier;
(c) allowing the intermediate formed in (b) to settle for a time sufficient in order to allow the air entrapped during step (b) to escape; and
(d) adding the viscosity modifier to the intermediate with mixing to produce a uniform paste.
The above steps are illustrative, but not limiting. For example, step (a) can be the last step.
In one embodiment of the formulation, the formulation is a paste containing isoxazoline compound, fumed silica, a viscosity modifier, an absorbent, a colorant; and a hydrophilic carrier which is triacetin, a monoglyceride, a diglyceride, or a triglyceride.

The compositions may be in the form of a sterile injectable aqueous or oleagenous suspension or an injectable solution. This suspension may be formulated according to the known art using those suitable dispersing or wetting agents and suspending agents which have been mentioned above. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally-acceptable diluent or solvent, for example, as a solution in 1,3-butane diol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution and isotonic sodium chloride solution. Cosolvents such as ethanol, propylene glycol glycerol formal or polyethylene glycols may also be used. Preservatives, such as phenol or benzyl alcohol, may be used.
In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables.
Topical, dermal and subdermal formulations can include emulsions, creams, ointments, gels, pastes, powders, shampoos, pour-on formulations, spot-on solutions and suspensions, dips and sprays. Topical application of an inventive compound or of a composition including at least one inventive compound among active agent(s) therein, in the form of a spot-on or pour-on composition, can allow for the inventive compound to be absorbed through the skin to achieve systemic levels, distributed through the sebaceous glands or on the surface of the skin achieving levels throughout the haircoat. When the compound is distributed through the sebaceous glands, they can act as a reservoir, whereby there can be a long-lasting effect (up to several months) effect. Spot-on formulations are typically applied in a localized region which refers to a relatively small area on the animal rather than to a large portion of the surface of the animal. In one embodiment of a localized region, the location is between the shoulders. In another embodiment of a localized region it is a stripe, e.g. a stripe from head to tail of the animal.
Pour-on formulations are described in U.S. Pat. No. 6,010,710, incorporated herein by reference.

Emulsifiers which can be used are, for example: calcium salts of alkylarylsulfonic acids, such as calcium dodecylbenzenesulfonate or nonionic emulsifiers, such as fatty acid polyglycol esters, alkylaryl polyglycol ethers, fatty alcohol polyglycol ethers, propylene oxide/ethylene oxide condensates, alkyl polyethers, sorbitan esters such as sorbitan fatty acid esters or polyoxyethylene sorbitan esters such as polyoxyethylene sorbitan fatty acid esters.
Dusts are obtained by grinding the active substance with finely divided solid substances, for example talc or natural clays, such as kaolin, bentonite or pyrophyllite, or diatomaceous earth.
Suspension concentrates may be water- or oil-based. They can be prepared, for example, by wet grinding by means of commercially available bead mills, if appropriate with addition of surfactants, as they have already been mentioned above for example in the case of the other formulation types.
Emulsions, for example oil-in-water emulsions (EW), can be prepared for example by means of stirrers, colloid mills and/or static mixtures using aqueous organic solvents and, if appropriate, surfactants as they have already been mentioned above for example in the case of the other formulation types.
Granules can be prepared either by spraying the compounds of formula (I) onto adsorptive, granulated inert material or by applying active substance concentrates onto the surface of carriers such as sand, kaolinites or of granulated inert material, by means of binders, for example polyvinyl alcohol, sodium polyacrylate or alternatively mineral oils. Suitable active substances can also be granulated in the manner which is conventional for the production of fertilizer granules, if desired in a mixture with fertilizers.
Water-dispersible granules are prepared, as a rule, by the customary processes such as spray-drying, fluidized-bed granulation, disk granulation, mixing in high-speed mixers and extrusion without solid inert material. To prepare disk, fluidized-bed, extruder and spray granules, see, for example, processes in “Spray-Drying Handbook” 3rd ed. 1979, G. Goodwin Ltd., London; J. E. Browning, “Agglomeration”, Chemical and Engineering 1967, pages 147 et seq.; “Perry's Chemical Engineer's Handbook”, 5th Ed., McGraw-Hill, New York 1973, p. 8-57. In general, the agrochemical preparations comprise a range selected from the group consisting of about 0.1 to about 99% by weight and about 0.1 to about 95% by weight, of compounds of formula (I).
The concentration of compounds of formula (I), (IA), (IB), (IC), (ID) and (IE) in wettable powders is, for example, about 10 to about 90% by weight, the remainder to 100% by weight being composed of customary formulation components. In the case of emulsifiable concentrates, the concentration of compounds of formula (I), (IA), (IB), (IC), (ID) and (IE) can amount to ranges selected from the group consisting of about 1% to about 90% and about 5% to about 80% by weight. Formulations in the form of dusts usually comprise in the range selected from the group consisting of about 1% to about 30% by weight of compounds of formula (I), (IA), (IB), (IC), (ID) and (IE) and about 5% to about 20% by weight of compounds of formula (I), (IA), (IB), (IC), (ID) and (IE). For sprayable solutions comprise a range selected from the group consisting of about 0.05% to about 80% by weight of compounds of formula (I), (IA), (IB), (IC), (ID) and (IE) and about 2% to about 50% by weight of compounds of formula (I). In the case of water-dispersible granules, the content of compounds of formula (I), (IA), (IB), (IC), (ID) and (IE) depends partly on whether the compounds of formula (I), (IA), (IB), (IC), (ID) and (IE) are in liquid or solid form and on which granulation auxiliaries, fillers and the like are being used. The water-dispersible granules, for example, comprise a range selected from the group consisting of between about 1 and about 95% and between about 10% and about 80% by weight.
In addition, the formulations of compounds of formula (I), (IA), (IB), (IC), (ID) and (IE) mentioned comprise, if appropriate, the adhesives, wetters, dispersants, emulsifiers, penetrants, preservatives, antifreeze agents, solvents, fillers, carriers, colorants, antifoams, evaporation inhibitors, pH regulators and viscosity regulators which are conventional in each case.

Imidacloprid is a well-known neonicotinoid active agent and is the key active ingredient in the topical parasiticide products Advantage®, Advantage® II, K9 Advantix®, and K9 Advantix® II sold by Bayer Animal Health. Agents of this class are described, for example, in U.S. Pat. No. 4,742,060 or in EP 0 892 060 (incorporated herein by reference).
In another embodiment, the neonicotinoid active agent is nitenpyram. Nitenpyram is the active ingredient in the oral product CAPSTARTM Tablets sold by Novartis Animal Health. Nitenpyram is active against adult fleas when given daily as an oral tablet. Nitenpyram works by interfering with normal nerve transmission and leads to the death of the insect. Nitenpyram has a very fast onset of action against fleas. For example, CAPSTARTM Tablets begin to act against fleas in as early as 30 minutes after administration and is indicated for use as often as once a day.
In certain embodiments, an insecticidal agent that can be combined with the isoxazoline compounds of the invention is a semicarbazone, such as metaflumizone.

Proton and fluorine magnetic resonance (respectively 1H NMR and 19F NMR) spectra were recorded on a Varian INOVA NMR spectrometer [400 MHz (1H) or 500 MHz (1H) and 377 MHz (19F)]. All spectra were determined in the solvents indicated. Chemical shifts are reported in ppm downfield of tetramethylsilane (TMS), referenced to the residual proton peak of the respective solvent peak for 1H NMR. Interproton coupling constants are reported in Hertz (Hz).
LC-MS spectra were obtained using two different systems. For LCMS method 1, LC-MS spectra were obtained using an Agilent 1200SL HPLC equipped with a 6130 mass spectrometer operating with electrospray ionization; chromatographic data were obtained using a Shimadzu Shim-pack XR-ODS, 3.0×30 mm, 2.2 micron particle size column and a water:methanol gradient from 15% methanol to 95% methanol in 2.2 minutes under a 1.5 mL/min flow; a hold at 95% methanol was applied at the end of the gradient for 0.8 minutes; and both water and methanol mobile phases contained 0.1% formic acid.
