Definitions
- the invention relates to the use of fluopyram for the control of endoparasites in humans and animals and to a method for the treatment of humans and in animals for the control of endoparasites.
- Endoparasites or especially helminthic nematodes such as e.g. Haemonchus contortus, Cooperia spp., Trichostrongylus spp. et al cause significant economic damage in the livestock of livestock.
- Other nematodes affect the health of pets, such as dogs and cats.
- Fluopyram is defined as compound according to formula (I)
- Respiratory chain by blocking the electron transport of the respiratory chain of the succinate dehydrogenase complex.
- Fluopyram with the chemical name N - ⁇ [3-chloro-5- (trifluoromethyl) -2-pyridinyl] ethyl ⁇ -2- (trifluoromethyl) -benzamide, and suitable processes for its preparation, starting from commercially available starting materials, in EP -A- 1 531 675.
- WO 2004/016088 describes pyridylethylbenzamides and their use as fungicides. The possibility of combining one or more of the disclosed pyridylethylbenzamide derivatives with other known fungicides, insecticides, nematicides or acaricides to broaden the spectrum of activity is also described.
- WO 2005/077901 teaches fungicidal compositions comprising at least one pyridylethylbenzamide and an inhibitor of electron transport in the respiratory chain of fungi.
- the patent application does not mention mixtures of pyridylethylbenzamides with insecticides.
- WO 2008/003738 teaches fungicidal compositions comprising at least one pyridylethylbenzamide and an insecticide.
- a possible nematicidal effect of the compositions is described in the application, but not explicitly for mixtures comprising N- ⁇ 2- [3-chloro-5- (trifluoromethyl) -2-pyridinyl] ethyl ⁇ -2-trifluoromethylbenzamide.
- the general nematicidal effect of fluopyram is described in WO-A 2008/126922.
- fluopyram is outstandingly suitable for controlling endoparasites, in particular of helminthic nematodes in humans and in animals. Accordingly, the subject of the present invention is the use of fluopyram for the control of endoparasites in humans and in animals
- control of endoparasites means a significant reduction of infestation by endoparasites compared to the untreated human or animal, preferably a substantial reduction (by 40-79%) compared to the untreated human or animal (100%). Particularly preferably, the infection is completely suppressed by endoparasites (by 70-100%) .
- the control can be curative, ie for the treatment of already infected humans or animals or protective, ie for the protection of hitherto uninfected humans or animals.
- Combinations of fluopyram with other drugs, including other endoparasiticides, may also be used in the control of endoparasites in the present invention.
- active compounds can be present in stereoisomeric forms or as stereoisomer mixtures, e.g. as enantiomers or racemates. Both the stereoisomer mixtures and the pure stereoisomers can be used according to the invention. It is also possible to use, where appropriate, salts of the active compounds with pharmaceutically acceptable acids or bases and also solvates, in particular hydrates, of the active substances or their salts.
- the active substances used in the products according to the invention may, depending on their structure, exist in stereoisomeric forms (enantiomers, diastereomers). According to the invention, the enantiomers or diastereomers and their respective mixtures can be used.
- the present invention also encompasses the use of the tautomeric forms.
- the active compounds can also be used in the form of their salts, solvates and solvates of the salts.
- Salts which are preferred in the context of the present invention are physiologically acceptable salts of the active compounds.
- Physiologically acceptable salts of the active compounds comprise acid addition salts of mineral acids, carboxylic acids and sulfonic acids, for example salts of hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid, methanesulfonic acid, ethanesulfonic acid, toluenesulfonic acid, benzenesulfonic acid, naphthalenedisulfonic acid, acetic acid, trifluoroacetic acid, propionic acid, depending on the structure of the active substance. Lactic acid, tartaric acid, malic acid, citric acid, fumaric acid, maleic acid and benzoic acid.
- Physiologically acceptable salts of the active compounds optionally also include salts of customary bases, such as, by way of example and by way of preference, alkali metal salts (for example sodium and potassium salts), alkaline earth salts (for example calcium and magnesium salts) and ammonium salts derived from ammonia or organic amines having 1 to 16 carbon atoms, such as, by way of example and by way of preference, ethylamine, diethylamine, triethylamine, ethyldiisopropylamine, monoethanolamine, diethanolamine, triethanolamine, dicyclohexylamine, dimethylaminoethanol, procaine, dibenzylamine, N-methylmorpholine, arginine, lysine, ethylenediamine, N-methylpiperidine and choline.
- customary bases such as, by way of example and by way of preference, alkali metal salts (for example sodium and potassium salts), alkaline earth salts (for example calcium and
- Solvates in the context of the invention are those forms of the active ingredients which form a complex in the solid or liquid state by coordination with solvent molecules. Hydrates are a special form of solvates that coordinate with water.
- the present invention also includes prodrugs of the active ingredients.
- prodrugs includes compounds which may themselves be biologically active or inactive, but are converted to the actual active ingredient during their residence time in the body (for example metabolically or hydrolytically).
- the agents according to the invention are suitable in the case of favorable warm-blooded toxicity for controlling pathogenic endoparasites which occur in humans and in animal husbandry and animal breeding in productive, breeding, zoo, laboratory, experimental and hobby animals. They are effective against all or individual stages of development of the pests and against resistant and normally sensitive endoparasite isolates.
- pathogenic Endoparasiten disease deaths and reductions in performance (eg in the production of meat, milk, wool, hides, eggs, honey, etc.) to be reduced, so that through the use of active ingredients more economical and easier animal husbandry is possible.

Description
Verwendung von Fluopyram zur Bekämpfung von Endoparasiten
Die Erfindung betrifft die Verwendung von Fluopyram zur Bekämpfung von Endoparasiten beim Menschen und bei Tieren sowie ein Verfahren zur Behandlung von Menschen und bei Tieren zur Bekämpfung von Endoparasiten. Endoparasiten oder speziell helminthische Nematoden wie z.B. Haemonchus contortus, Cooperia spp., Trichostrongylus spp. u.a. verursachen erhebliche ökonomische Schäden bei der Tierhaltung von Nutztieren. Andere Nematoden beeinträchtigen die Gesundheit von Hobbytieren, wie Hunde und Katzen.
Es besteht daher ein dringender Bedarf an Anthelmintika, insbesondere Nematiziden., die eine ausreichende Bekämpfung von Endoparasiten beim Menschen und bei Tieren ermöglichen. Es ist bereits bekannt, dass bestimmte Pyridylethylbenzamide fungizide, insektizide und akarizide und nematizide Eigenschaften besitzen.
Fluopyram ist definiert als Verbindung gemäß Formel (I)
Atmungskette, indem der Elektronentransport der Atmungskette des Succinat-Dehydrogenase Komplex blockiert wird.
Fluopyram mit dem chemischen Namen N-{[3-chlor-5-(trifluorinethyl)-2-pyridi.nyl]ethyl}-2- (trifluoromethyI)benzamide und geeignete Verfahren zu dessen Herstellung sind, ausgehend von kommerziell zugänglichen Ausgangsstoffen, in EP-A- 1 531 675 beschrieben. WO 2004/016088 beschreibt Pyridylethylbenzamide und deren Verwendung als Fungizide. Die Möglichkeit einer Kombination eines oder mehrerer der offenbarten Pyridylethylbenzamid Derivate mit weiteren bekannten Fungiziden, Insektiziden, Nematiziden oder Akariziden zur Verbreiterung des Aktivitätsspektrums wird ebenfalls beschrieben. WO 2005/077901 lehrt fungizide Zusammensetzungen umfassend wenigstens ein Pyridylethylbenzamid und einen Inhibitor des Elcktronentransports in der Atmungskette von Pilzen. Die Patentanmeldung erwähnt jedoch keine Mischungen von Pyridylethylbenzamiden mit Insektiziden. WO 2008/003738 lehrt fungizide Zusammensetzungen, umfassend wenigstens ein pyridylethylbenzamid und ein Insektizid. Eine mögliche nematizide Wirkung der Zusammensetzungen wird in der Anmeldung beschrieben, jedoch nicht explizit für Mischungen umfassend N-{2-[3-Chlor-5-(trifluormethyl)-2-pyridinyl]ethyl}-2-trifluormethylbenzamid.
Die generelle nematizide Wirkung von Fluopyram ist in der WO-A 2008/126922 beschrieben.
Überraschenderweise wurde nun gefunden, dass Fluopyram, hervorragend zur Bekämpfung von Endoparasiten, insbesondere von helminthischen Nematoden beim Menschen und bei Tieren geeignet ist. Der Gegenstand der vorliegenden Erfindung ist demnach die Verwendung von Fluopyram zur Bekämpfung von Endoparasiten beim Menschen und bei Tieren
Im Zusammenhang mit der vorliegenden Erfindung bedeutet„Bekämpfung von Endoparasiten" eine signifikante Verminderung des Befalls durch Endoparasiten verglichen mit dem unbehandelten Mensch oder Tier, vorzugsweise eine wesentliche Verminderung (um 40-79 %), verglichen mit dem unbehandelten Mensch oder Tier, (100%), besonders bevorzugt wird die Infektion durch Endoparasiten vollständig unterdrückt (um 70-100%). Die Bekämpfung kann dabei kurativ, d.h. zur Behandlung bereits infizierter Menschen oder Tiere oder protektiv, d.h. zum Schutz bislang nicht infizierter Menschen oder Tiere erfolgen.
Kombinationen von Fluopyram mit anderen Wirkstoffen, unter anderem mit anderen Endoparasitiziden können bei der Bekämpfung von Endoparasiten im Rahmen der vorliegenden Erfindung ebenfalls Anwendung finden.
Wirkstoffe können je nach Struktur in stereoisomeren Formen oder als Stereoisomerengemische vorliegen, z.B. als Enantiomere oder Racemate. Sowohl die Stereoisomerengemische als auch die reinen Stereoisomeren können erfindungsgemäß verwendet werden. Weiterhin können gegebenenfalls verwendet werden: Salze der Wirkstoffe mit pharmazeutisch annehmbaren Säuren oder Basen und auch Solvate, insbesondere Hydrate, der Wirkstoffe oder ihrer Salze.
Die in den erfindungsgemäßen Erzeugnissen verwendeten Wirkstoffe können in Abhängigkeit von ihrer Struktur in stereoisomeren Formen (Enantiomere, Diastereomere) existieren. Erfindungsgemäß könne die Enantiomeren oder Diastereomeren und ihre jeweiligen Mischungen eingesetzt werden.
Sofern die Wirkstoffe in tautomeren Formen vorkommen können, umfasst die vorliegende Erfindung auch den Einsatz der tautomeren Formen.
Die Wirkstoffe können gegebenenfalls auch in Form ihrer Salze, Solvate und Solvate der Salze eingesetzt werden Als Salze sind im Rahmen der vorliegenden Erfindung physiologisch unbedenkliche Salze der Wirkstoffe bevorzugt.
Physiologisch unbedenkliche Salze der Wirkstoffe umfassen je nach Struktur des Wirkstoffs Säureadditionssalze von Mineralsäuren, Carbonsäuren und Sulfonsäuren, z.B. Salze der Chlorwasserstoffsäure, Bromwasserstoffsäure, Schwefelsäure, Phosphorsäure, Methansulfonsäure, Ethan- sulfonsäure, Toluolsulfonsäure, Benzolsulfonsäure, Naphthalindisulfonsäure, Essigsäure, Trifluor- essigsäure, Propionsäure, Milchsäure, Weinsäure, Äpfelsäure, Zitronensäure, Fumarsäure, Maleinsäure und Benzoesäure.
Physiologisch unbedenkliche Salze der Wirkstoffe umfassen gegebenenfalls auch Salze üblicher Basen, wie beispielhaft und vorzugsweise Alkalimetallsalze (z.B. Natrium- und Kaliumsalze), Erdalkalisalze (z.B. Calcium- und Magnesiumsalze) und Ammoniumsalze, abgeleitet von Ammoniak oder organischen Aminen mit 1 bis 16 C-Atomen, wie beispielhaft und vorzugsweise Ethylamin, Diethylamin, Triethylamin, Ethyldiisopropylamin, Monoethanolamin, Diethanolamin, Triethanolamin, Dicyclohexylamin, Dimethylaminoethanol, Prokain, Dibenzylamin, N-Methylmorpholin, Arginin, Lysin, Ethylendiamin, N-Methylpiperidin und Cholin.
Als Solvate werden im Rahmen der Erfindung solche Formen der Wirkstoffe bezeichnet, welche in festem oder flüssigem Zustand durch Koordination mit Lösungsmittelmolekülen einen Komplex bilden. Hydrate sind eine spezielle Form der Solvate, bei denen die Koordination mit Wasser erfolgt.
Außerdem umfasst die vorliegende Erfindung auch Prodrugs der Wirkstoffe. Der Begriff„Prodrugs" umfasst Verbindungen, welche selbst biologisch aktiv oder inaktiv sein können, jedoch während ihrer Verweilzeit im Körper zu dem eigentlichen Wirkstoff umgesetzt werden (beispielsweise metabolisch oder hydrolytisch).
Die erfindungsgemäßen Mittel eignen sich bei günstiger Warmblütertoxizität zur Bekämpfung von pathogenen Endoparasiten, die bei Menschen und in der Tierhaltung und Tierzucht bei Nutz-, Zucht-, Zoo-, Labor-, Versuchs- und Hobbytieren vorkommen. Sie sind dabei gegen alle oder einzelne Entwicklungsstadien der Schädlinge sowie gegen resistente und normal sensible Endoparasiten-Isolate wirksam. Durch die Bekämpfung der pathogenen Endoparasiten sollen Krankheit, Todesfälle und Leistungsminderungen (z.B. bei der Produktion von Fleisch, Milch, Wolle, Häuten, Eiern, Honig usw.) vermindert werden, so dass durch den Einsatz der Wirkstoffe eine wirtschaftlichere und einfachere Tierhaltung möglich ist.
