FIELD OF THE INVENTION

This invention relates to certain methods for combating biting flies and blowflies on animals.

BACKGROUND OF THE INVENTION

Flies are not just a nuisance; they carry diseases which pose a serious health hazard to people and animals. Globally, they cause livestock and poultry production losses estimated in the billions of dollars. The growth and performance of nearly all farmed animals are adversely affected by flies, especially when they are present in high numbers. Infested animals become harassed and feed intake is drastically reduced. The result: significant reductions of meat, milk and egg production and serious economic losses.

Non-biting flies often feed on secretions from the eyes, nose and any small wounds of livestock This distracts animals from grazing, causing a reduction in growth and productivity. Non-biting flies are not key vectors of any specific disease organisms, but because of their feeding and reproduction habits, and the structure of their feet and mouthparts, they can act as mechanical vectors for a whole range of pathogens, from viruses to helminthes.

Biting flies can cause even greater irritation to domestic animals, and they too are vectors for disease transmission. However, because they feed on blood, they can also cause anemia and hypersensitivity. Biting flies therefore are considered by some to be a more serious problem in livestock production than non-biting flies.

However some non-biting flies often designated â€œblowfliesâ€ cause significant damage in their own right by virtue of their propensity to cause â€œmyiesisâ€ in susceptible animals. Myiasis is an animal or human disease caused by parasitic dipterous fly larvae feeding on the host's necrotic or living tissue. Blowflies are the single most important parasite of the sheep industry in Australia. Losses are estimated at more than $50 million yearly. These losses are caused by reduced growth of the sheep, reduced and inferior wool production, and extremely high labour costs expended in attempts to control the parasite.

Under normal conditions, blowflies do not attack live healthy sheep. If animals suffer open wounds, for example from branding or castration, some species of blowflies, deposit eggs in the wounds. These will hatch into maggots which eat the flesh of the animal.

The principal control method of adult populations of biting flies and blowflies involves topical insecticide applications to the livestock. Organophosphorus or organochlorine compounds are often used, usually in a spraying formulation.

There is a compelling need for improved insecticide formulations useful in the treatment and prevention of myiasis and the control of biting flies which the present invention addresses.

One skilled in the art will appreciate that not all nitrogen-containing heterocycles can form N-oxides since the nitrogen requires an available lone pair for oxidation to the oxide; one skilled in the art will recognize those nitrogen-containing heterocycles which can form N-oxides. One skilled in the art will also recognize that tertiary amines can form N-oxides. Synthetic methods for the preparation of N-oxides of heterocycles and tertiary amines are very well known by one skilled in the art including the oxidation of heterocycles and tertiary amines with peroxy acids such as peracetic and m-chloroperbenzoic acid (MCPBA), hydrogen peroxide, alkyl hydroperoxides such as t-butyl hydroperoxide, sodium perborate, and dioxiranes such as dimethydroxirane. These methods for the preparation of N-oxides have been extensively described and reviewed in the literature, see for example: T. L. Gilchrist in Comprehensive Organic Synthesis, vol. 7, pp 748-750, S. V. Ley, Ed., Pergamon Press; M. Tisler and B. Stanovnik in Comprehensive Heterocyclic Chemistry, vol. 3, pp 18-20, A. J. Boulton and A. McKillop, Eds., Pergamon Press; M. R. Grimmett and B. R. T. Keene in Advances in Heterocyclic Chemistry, vol. 43, pp 149-161, A. R. Katritzky, Ed., Academic Press; M. Tisler and B. Stanovnik in Advances in Heterocyclic Chemistry, vol. 9, pp 285-291, A. R. Katritzky and A. J. Boulton, Eds., Academic Press; and G. W. H. Cheeseman and E. S. G. Werstiuk in Advances in Heterocyclic Chemistry, vol. 22, pp 390-392, A. R. Katritzky and A. J. Boulton, Eds., Academic Press.

Compounds of this invention can exist as one or more stereoisomers. The various stereoisomers include enantiomers, diastereomers, atropisomers and geometric isomers. One skilled in the art will appreciate that one stereoisomer may be more active and/or may exhibit beneficial effects when enriched relative to the other stereoisomer(s) or when separated from the other stereoisomer(s). Additionally, the skilled artisan knows how to separate, enrich, and/or to selectively prepare said stereoisomers. Accordingly, the present invention comprises compounds selected from Formula 1, N-oxides and salts thereof. Pharmaceutically or veterinarily acceptable salts, suitable to the mode of administration, are contemplated. The compounds of the invention may be present as a mixture of stereoisomers, individual stereoisomers, or as an optically active form.

The salts of the compounds of the invention include acid-addition salts with inorganic or organic acids such as hydrobromic, hydrochloric, nitric, phosphoric, sulfuric, acetic, butyric, fumaric, lactic, maleic, malonic, oxalic, propionic, salicylic, tartaric, 4-toluenesulfonic or valeric acids. In the compositions and methods of this invention, the salts of the compounds of the invention are preferably acceptable for the veterinary/pharmaceutical uses described herein.

The preferred compositions of the present invention are those, which comprise the above preferred compounds. The preferred methods of use are those involving the above-preferred compounds.

â€œFliesâ€ are insects in the order Diptera, meaning â€œtwo-wingedâ€ . True flies have one pair of wings used for flying. Posterior to the wings is a pair of stalked knob-like structures (called halteres), which are organs of balance. Flies undergo complete metamorphosis, i.e. the life cycle consists of the following stages: egg, larva (called a maggot), pupa, and adult. Each stage of the life cycle may be a target for control and intervention.

Flies may be categorized into two functional categories â€œbitingâ€ and â€œnon-bitingâ€ . â€œBiting fliesâ€ have specially adapted mouthparts well suited for piercing the host animal integument. The stable fly Stomoxys calcitrans is a good example of a biting fly. The stable fly has a proboscis which is used to pierce the skin and imbibe blood. Both the males and the females are bloodfeeders. The stable fly is often the only biting, blood-sucking fly breeding in any appreciable numbers in and around confined-animal production facilities. Another example of a biting fly is the horn fly, Haematobia irritans irritans, which like the stable fly is a bloodsucker and has great economic impact. Like the stable fly the horn fly has piercing/sucking mouthparts.

â€œBlowfliesâ€ are defined as flies which are the etiologic agent of myiasis. By way of example the Calliphoridae family, together with the Sarcophagidae and the Oestridae families, contain the species largely responsible for many of the important myiases of domestic animals and man. Major species of blowflies include Lucilia sericata (greenbottles), Phormia terraenovae (blackbottles), Calliphora erythrocephala and Calliphora. vomitoria (bluebottles) in Europe. These flies are characterized by the color of the metallic sheen on their body sections. Lucilia cuprina, L. caeser, L. illustris, Phormia regina, Calliphora stygia, C australis, C. fallax, Chrysomyia albiceps, C. chlorophyga, C. micropogon, and C. rufifacies are examples of major species of blowflies in the tropics and subtropics. Blowflies are a particularly important problem in sheep farming.

The blowflies that attack sheep fall into two main categories:
(1) Primary flies, which are capable of initiating a strike on living sheep. These include Lucilia and Phormia spp. and some Calliphora spp.
(2) Secondary flies, which cannot initiate a strike, but attack an area already struck or otherwise damaged. They frequently extend the injury, rendering the strike one of great severity. Examples include many Calliphora spp. and, in warmer climates, Chrysomyia spp.

A â€œparasiticidally effective amountâ€ is the amount of active ingredient needed to achieve an observable effect diminishing the occurrence or activity of the target invertebrate parasite pest. One skilled in the art will appreciate that the parasitically effective dose can vary for the various compounds and compositions of the present invention, the desired parasitical effect and duration, the target invertebrate pest species, the animal to be protected, the mode of application and the like, and the amount needed to achieve a particular result can be determined through simple experimentation

â€œMyiasisâ€ is an animal disease caused by parasitic dipterous fly larvae feeding on the animal host's necrotic or living tissue. Colloquialisms for myiasis include â€œfly-strikeâ€ and â€œfly-blownâ€ . Blowfly myiasis is often associated with sheep; however, many other animals may be affected.

â€œTreatingâ€ or â€œTreatmentâ€ as it applies to myiasis or infestation refers to both the prevention and control of myiasis or infestation respectively

The invention described herein relates to a method of controlling or prevention of infestations of flies on an animal by applying to the animal a parasiticidally effective amount of a compound of Formula 1.

Application of Compounds of the Invention

The compound of Formula 1 of this invention can be applied to any animal, including herd animals, that can be bothered by flies or afflicted by myiasis. The compositions can be applied, for example, to cattle, sheep, goats, horses, donkeys, camels, pigs, reindeer, caribou and buffalo. Humans may also be treated.

The â€œapplyingâ€ can be accomplished by way of non limiting example, whole-animal sprays, self-applicating devices, pour on treatments and controlled-release devices, such as ear tags and tapes, neck collars, ear tags, tail bands, limb bands or halters which comprise compounds or compositions comprising compounds of Formula 1. In addition to sprays and pour on treatments, application may be by other forms of topical administration, for example, in the form of immersion or dipping, washing, coating with powder, or application to a small area of the animal.

Application of the compositions according to the invention to the animals to be treated is done topically via solutions, emulsions, suspensions, (drenches), powders, and pour-on formulations.

The pour-on or spot-on method consists in applying the compound of Formula 1 to a specific location of the skin or coat, advantageously to the neck or backbone of the animal. This takes place e.g. by applying a swab or spray of the pour-on or spot-on formulation to a relatively small area of the coat, from where the active substance is dispersed almost automatically over wide areas of the fur owing to the spreading nature of the components in the formulation and assisted by the animal's movements.

The compounds of Formula 1 may be indirectly applied to an animal by applying it to the local environment in which the animal dwells (such as bedding, enclosures, or the like).

Whole-animal sprays provide rapid relief from fly pressure. Animal sprays are applied either as a dilute coarse spray, often applied under high pressure to soak the skin, or as a fine low-volume, more concentrated mist.

Self-applicating devices include back rubber covered with an absorbent material treated with an insecticide-oil solution, or dust bags filled with an insecticidal dust. Back rubbers and dustbags should be placed in gateways, near water and feed source, and in other areas where animals will make frequent contact with them.

Controlled-release ear tags and tapes are generally very effective for fly control in certain farm areas.

Pour-on treatments involves the application of an insecticide along the backline of the animal at a prescribed dosage of topical products. The pour-on or spot-on method is especially advantageous for use on herd animals such as cattle, horses, sheep or pigs, in which it is difficult or time-consuming to treat all the animals by more labor intensive methods of administration.

The compounds according to the invention are especially effective against fly larvae. The active compounds are employed in known manner, preferably by dermal or topical use, for example in the form of dipping, spraying, pour-on and spot-on, and powdering.

Blowfly strikes are almost always fatal unless the sheep is caught, the wool clipped from the infected area, the maggots scraped out, disinfectant or antibiotic and insecticide applied to prevent further strikes. Treatment of blowfly strike should aim to kill any maggots present, prevent the likelihood of further fly strike and assist the wound heal. The wool should be carefully clipped away from around the wound and surrounding area. A cream containing the compound of Formula 1 can be applied to the infected areas. Mild cases should heal quickly with correct treatment.

It is also effective to treat myiasis afflicted sheep or those at risk of being afflicted by dipping. It is particularly important to immerse sheep for at least a full minute so as to ensure the dip saturates the whole fleece and regular replenishment of dip baths is important to maintain the strength of dip concentrate. Pour-ons would also be an effective treatment

Compositions of the Invention

The compounds of the invention may be applied alone but are typically formulated into a veterinary or pharmaceutical composition. The compounds are prepared or formulated into compositions in a known manner, for example by extending the active compounds with solvents and/or carriers, if appropriate using emulsifiers and/or dispersing agents; if, for example, water is used as the diluent, organic solvents can, if appropriate, be used as auxiliary solvents.

Typically a composition used in the present invention comprises a mixture of a compound of Formula 1, an N-oxide or a salt thereof, with one or more pharmaceutically or veterinarily acceptable carriers comprising excipients and auxiliaries selected with regard to their suitability for topical administration and in accordance with standard practice. In addition, a suitable carrier is selected on the basis of compatibility with the one or more active ingredients in the composition, including such considerations as stability relative to pH and moisture content. The typical application medium will be a composition for protecting an animal from an invertebrate parasitic pest comprising a parasitically effective amount of a compound of Formula 1 and at least one carrier.

Formulations for topical administration are typically in the form of a powder, cream, suspension, spray, emulsion, foam, paste, aerosol, ointment, salve or gel. More typically a topical formulation is a water-soluble solution, which can be in the form of a concentrate that is diluted before use. Parasiticidal compositions suitable for topical administration typically comprise a compound of the present invention and one or more topically suitable carriers. In applications of a parasiticidal composition topically to the exterior of an animal as a line or spot (i.e. â€œspot-onâ€ treatment), the active ingredient migrates over the surface of the animal to cover most or all of its external surface area. As a result, the treated animal is particularly protected from invertebrate pests that feed off the epidermis of the animal such as ticks, fleas and lice. Therefore formulations for topical localized administration often comprise at least one organic solvent to facilitate transport of the active ingredient over the skin and/or penetration into the epidermis of the animal. Carriers in such formulations include propylene glycol, paraffins, aromatics, esters such as isopropyl myristate, glycol ethers, alcohols such as ethanol, n-propanol, 2-octyl dodecanol or oleyl alcohol; solutions in esters of monocarboxylic acids, such as isopropyl myristate, isopropyl palmitate, lauric acid oxalic ester, oleic acid oleyl ester, oleic acid decyl ester, hexyl laurate, oleyl oleate, decyl oleate, caproic acid esters of saturated fatty alcohols of chain length C₁₂-C₁₈; solutions of esters of dicarboxylic acids, such as dibutyl phthalate, diisopropyl isophthalate, adipic acid diisopropyl ester, di-n-butyl adipate or solutions of esters of aliphatic acids, e.g., glycols. It may be advantageous for a crystallization inhibitor or a dispersant known from the pharmaceutical or cosmetic industry also to be present.

A pour-on formulation may also be prepared for control of parasites in an animal of agricultural worth. The pour-on formulations of this invention can be in the form of a liquid, powder, emulsion, foam, paste, aerosol, ointment, salve or gel. Typically, the pour-on formulation is liquid. These pour-on formulations can be effectively applied to sheep, cattle, goats, other ruminants, camelids, pigs and horses. The pour-on formulation is typically applied by pouring in one or several lines or in a spot-on the dorsal midline (back) or shoulder of an animal. More typically, the formulation is applied by pouring it along the back of the animal, following the spine. The formulation can also be applied to the animal by other conventional methods, including wiping an impregnated material over at least a small area of the animal, or applying it using a commercially available applicator, by means of a syringe, by spraying or by using a spray race. The pour-on formulations include a carrier and can also include one or more additional ingredients. Examples of suitable additional ingredients are stabilizers such as antioxidants, spreading agents, preservatives, adhesion promoters, active solubilisers such as oleic acid, viscosity modifiers, UV blockers or absorbers, and colourants. Surface active agents, including anionic, cationic, non-ionic and ampholytic surface active agents, can also be included in these formulations.

The formulations of this invention often include an antioxidant, such as BHT (butylated hydroxytoluene). The antioxidant is generally present in amounts of at 0.1-5% (wt/vol). Some of the formulations require a solubilizer, such as oleic acid, to dissolve the active agent. Common spreading agents used in these pour-on formulations are: isopropyl myristate (IPM), isopropyl palmitate (IPP), caprylic/capric acid esters of saturated C₁₂-C₁₈fatty alcohols, oleic acid, oleyl ester, ethyl oleate, triglycerides, silicone oils and dipropylene glycol monomethyl ether (DPM). The pour-on formulations of this invention are prepared according to known techniques. Where the pour-on is a solution, the parasiticide/insecticide is mixed with the carrier or vehicle, using heat and stirring where required. Auxiliary or additional ingredients can be added to the mixture of active agent and carrier, or they can be mixed with the active agent prior to the addition of the carrier. If the pour-on is an emulsion or suspension, these formulations are similarly prepared using known techniques.

Other delivery systems for relatively hydrophobic pharmaceutical compounds may be employed. Liposomes and emulsions are well-known examples of delivery vehicles or carriers for hydrophobic drugs. In addition, organic solvents such as dimethylsulfoxide may be used.

The compounds of Formula 1 are generally present in the compositions in concentrations of 0.1 to 95 percent by weight, preferably 0.5 to 90 percent by weight. Preparations which are intended for direct application contain the active compound according to the invention in concentrations of between 0.001 and 5 percent by weight, preferably 0.005 to 3 percent by weight.

Dosages may range from 0.0001 mg/kg of animal body weight to about 1000 mg/kg. of the compound of Formula 1. Sometimes dosages may be from 0.1 mg/kg of animal body weight to about 200 mg/kg. Often times it would be advantageous to administer amounts of about 0.01 to about 100 mg or between 0.02 to about 50 mg/kg. and frequently between 0.1 and 75 mg/kg. Preferably, the treatment is carried out so as to administer to the animal a dose of from 0.1 to 40 mg/kg and in particular from 1 to 30 mg/kg. Administration may be given as a single dose or intermittent in time and may be administered daily, weekly, monthly, bimonthly or quarterly in order to achieve effective results in order to achieve effective results.

Nevertheless it can at times be necessary to deviate from the amounts mentioned, and in particular to do so in accordance with the body weight of the test animal and/or the method of application, but also because of the species of animal and its individual behavior towards the medicament, or the nature of the formulation of the latter and the time or interval at which it is administered. Thus it can suffice in some cases to manage with less than the above mentioned minimum amount while in other cases the upper limit mentioned must be exceeded. Where substantial amounts are applied, it can be advisable to divide these into several individual administrations over the course of the day. The general sense of the other statements made above also applies.

Pour-on or spot-on formulations suitably contain carriers, which promote rapid dispersement over the skin surface or in the coat of the host animal, and are generally regarded as spreading oils. Suitable carriers are e.g. oily solutions; alcoholic and isopropanolic solutions such as solutions of 2-octyldodecanol or oleyl alcohol; solutions in esters of monocarboxylic acids, such as isopropyl myristate, isopropyl palmitate, lauric acid oxalate, oleic acid oleyl ester, oleic acid decyl ester, hexyl laurate, oleyl oleate, decyl oleate, capric acid esters of saturated fat alcohols of chain length C.sub.12-C.sub.18; solutions of esters of dicarboxylic acids, such as dibutyl phthalate, diisopropyl isophthalate, adipic acid diisopropyl ester, di-n-butyl adipate or also solutions of esters of aliphatic acids, e.g. glycols. It may be advantageous for a dispersing agent to be additionally present, such as one known from the pharmaceutical or cosmetic industry. Examples are 2-pyrrolidone, 2-(N-alkyl)pyrrolidone, acetone, polyethylene glycol and the ethers and esters thereof, propylene glycol or synthetic triglycerides.

The oily solutions include e.g. vegetable oils such as olive oil, groundnut oil, sesame oil, pine oil, linseed oil or castor oil. The vegetable oils may also be present in epoxidised form. Paraffins and silicone oils may also be used.

A pour-on or spot-on formulation generally contains 1 to 20% by weight of a compound of Formula 1, 0.1 to 50% by weight of dispersing agent and 45 to 98.9% by weight of solvent.

Importantly the compounds of Formula 1 may be indirectly applied to an animal by applying it to the local environment in which the animal dwells (such as bedding, enclosures, or the like). Effective use rates will range from about 1.0 to 50 mg/square meter but as little as 0.1 mg/square meter may be sufficient or as much as 150 mg/square meter may be required. One skilled in the art can easily determine the biologically effective amount necessary for the desired level of pest control.

The Compositions of the Invention May Comprise Additional Active Compounds

It is contemplated that additional biologically active compounds may be administered at the same time or separately over time to obtain broader spectrum of pest control or to attack adult fleas. Such additional biologically active compounds may be packaged together with the compound of Formula 1 as a kit. For convenience sake such additional biologically active compounds may be formulated into the same composition containing the compound of Formula 1. Therefore the present invention contemplates the use of compositions characterised in that they contain, in addition to a compound of Formula 1, further auxiliaries and/or active compounds, such as additional biologically active compounds, disinfectants or antibiotics may be admixed to the formulations, or the ready-to-use solutions, in addition to the customary solid or liquid extenders, diluents and/or surface-active agents.

Of note are additional biologically active compounds or agents selected from art-known anthelmintics, such as, for example, avermectins (e.g. ivermectin, moxidectin, milbemycin), benzimidazoles (e.g. albendazole, triclabendazole), salicylanilides (e.g. closantel, oxyclozanide), substituted phenols (e.g. nitroxynil), pyrimidines (e.g. pyrantel), imidazothiazoles (e.g. levamisole) and praziquantel.

Other biologically active compounds or agents useful in the compositions of the present invention can be selected from Insect Growth Regulators (IGRs) and Juvenile Hormone Analogues (JHAs) such as diflubenzuron, triflumuron, fluazuron, cyromazine, methoprene, etc., thereby providing both initial and sustained control of parasites (at all stages of insect development, including eggs) on the animal subject, as well as within the environment of the animal subject.

The compounds of Formula I according to the invention may be used alone or in combination with other biocides. They may be combined with pesticides having the same sphere of activity e.g. to increase activity, or with substances having another sphere of activity e.g. to broaden the range of activity. It can also be sensible to add so-called repellents. If the range of activity is to be extended to endoparasites, e.g. wormers, the compounds of Formula 1 are suitably combined with substances having endoparasitic properties. Of course, they can also be used in combination with antibacterial compositions.

Preferred groups of combination partners and especially preferred combination partners are named in the following, whereby combinations may contain one or more of these partners in addition to a compound of Formula 1.

As a rule, the anthelminthic compositions according to the invention contain 0.1 to 99% by weight, especially 0.1 to 95% by weight of active ingredient of Formula 1 mixtures thereof, 99.9 to 1% by weight, especially 99.8 to 5% by weight of a solid or liquid admixture, including 0 to 25% by weight, especially 0.1 to 25% by weight of a surfactant.

As noted above, in another embodiment of the process according to the invention, compounds of Formula 1 and the additional compounds noted hereinbefore may be applied in a distinct and separate manner over time.

The following TESTS demonstrate the control efficacy of compounds of this invention on specific pests. The pest control protection afforded by the compounds is not limited, however, to these species.

BIOLOGICAL EXAMPLES OF THE INVENTIONTest A

Adult L. serricata (blowflies): Adult flies are placed on beds of blood agar (in individual test wells; 4 flies per well) in which test compound (3-bromo-1-(3-chloro-2-pyridinyl)-N-[4-cyano-2-methyl-6-[(methylamino)carbonyl]phenyl]-1H-pyrazole-5-carboxamide) was dissolved/suspended prior to hardening of agar. Flies can take up test compound by both ingestion and contact. Assays are scored by number of dead flies at 2 hours, 4 hours, and 24 hours.

L. serricata (Insect; Blowfly) Larvae.

Test compound (3-bromo-1-(3-chloro-2-pyridinyl)-N-[4-cyano-2-methyl-6-[(methylamino)-carbonyl]phenyl]-1H-pyrazole-5-carboxamide) was mixed with dried blood bovine serum and placed on filter paper discs. Newly emerged larvae of blowfly, Lucilica sericata were added to the filter paper, which were ingested by larvae. Activity may occur through both feeding and contact. Four replicates were run per data point. Activity was assessed at 24 hours.

Results: Test compound gave 90-100% mortality at 0.5 ppm at 24 hours. Fipronil gave 90-100% mortality at 0.5 ppm at 24 hours.

Although the present invention and its advantages have been described in detail, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
