Diese neuen Verbindungen sind wirksame Mittel gegen Schistosomiasis. Sie sind dem bekannten, in gleicher Weise wirksamen 4-(3'-Chlor-4'-methylphenyl)-piperazinoessigsäuremethylester überlegen, wie aus folgenden Vergleichsversuchen hervorgeht: Albinomäuse wurden mit S.-Mansoni-Larven infiziert und 6 Wochen in Käfigen gehalten, worauf man auf die Anwesenheit von Eiern erwachsener Schistosomen in den Faeces prüfte. These new compounds are effective agents against schistosomiasis. They are the known, equally effective methyl 4- (3'-chloro-4'-methylphenyl) piperazinoacetate consider, as can be seen from the following comparative experiments: Albino mice became infected with S. Mansoni larvae and kept in cages for 6 weeks, whereupon examined the presence of eggs of adult schistosomes in the faeces.
Die Verbindungen wurden an Gruppen von je drei Mäusen auf ihre Wirksamkeit und Toxizität geprüft. The compounds were tested on groups of three mice each for their effectiveness and toxicity tested.
Verschiedene Dosierungen der zu prüfenden Verbindungen wurden oral mittels Magensonde einmal täglich an 5 aufeinanderfolgenden Tagen verabreicht.Various dosages of the compounds to be tested were given orally administered by gastric tube once daily for 5 consecutive days.
3 Wochen später wurden die Mäuse getötet und die je Maus gefundene Anzahl erwachsener Würmer vermerkt. Bei den infizierten, nicht behandelten Vergleichstieren wurden je Maus fünfunddreißig Würmer gefunden. Wurde der 4-(3'-Chlor-4'-methylphenyl)-piperazino-essigsäuremethylester (deutsche Auslegeschrift 1 060401) oral in einer Dosierung von 50mglkg täglich STage lang gegeben, so wurden nach 3 Wochen je Maus dreißig Würmer gefunden, woraus die geringe Wirksamkeit dieser Verbindung hervorgeht. Wurde diese Verbindung oral in einer Dosierung von 1500 mglkg gegeben, so verendeten alle Mäuse innerhalb von 18 Stunden, was die hohe Toxizität dieser Verbindung zeigt.3 weeks later, the mice were sacrificed and each mouse was found Number of adult worms noted. In the infected, untreated comparison animals Thirty-five worms were found per mouse. Was the 4- (3'-chloro-4'-methylphenyl) -piperazino-acetic acid methyl ester (German Auslegeschrift 1 060401) orally in a dosage of 50mglkg daily STage given for a long time, thirty worms were found per mouse after 3 weeks, from which the the poor effectiveness of this compound is evident. Was this compound orally in Given a dose of 1500 mglkg, all mice died within 18 Hours, which shows the high toxicity of this compound.
Die Dosierungen der erfindungsgemäß erhältlichen Verbindungen in
mglkg täglich, die, über 5 Tage verabreicht, 900/0 oder mehr der Würmer töteten,
und die Toxizitäten der geprüften Verbindungen sind in nachstehender Tabelle angegeben:
Man kann auch die in dem Filtrat enthaltene freie Base mit ätherischem Bromwasserstoff oder anderen Säuren zur Reaktion bringen, um das entsprechende Hydrobromid, Hydrojodid, Sulfat, Phosphat, Acetat, Benzoat, Salicylat, Glycolat, Succinat, Nicotinat, Ascorbat, Tartrat, Maleat oder Lactat herzustellen.The free base contained in the filtrate can also be mixed with ethereal Bring hydrogen bromide or other acids to reaction to form the corresponding hydrobromide, Hydroiodide, sulfate, phosphate, acetate, benzoate, salicylate, glycolate, succinate, nicotinate, Ascorbate, To produce tartrate, maleate or lactate.
Die als Ausgangsstoffe benötigten Verbindungen der allgemeinen Formeln II und III sind bekannt oder können nach bekannten Verfahren hergestellt werden. The compounds of the general formulas required as starting materials II and III are known or can be prepared by known processes.
Das erfindungsgemäße Verfahren wird durch nachstehende Beispiele näher erläutert. The method according to the invention is illustrated by the following examples explained in more detail.
Beispiel 1 1-(3'-Chlor-4'-methylphenyl)-4-(p- [tert.-amyl]-phenoxyhexamethylen)-piperazin Ein Gemisch von 10,6 g (0,05 Mol) l-(3'-Chlor-4'-methylphenyl)-piperazin, 16,4 g (0,05 Mol) p-(tert.-Amyl)- phenoxy- hexamethylen- bromid, 10,1 g (0,10 Mol) Triäthylamin und 125 ml Toluol wurden über Nacht unter Rückfluß gekocht. Das Reaktionsgemisch wurde dann filtriert und das Filtrat konzentriert. Der Rückstand wurde in Ather gelöst und mit alkoholischem Chlorwasserstoff behandelt, um das gewünschte Reaktionsprodukt in Form seines Hydrochlorids auszufällen, das nach Umkristallisieren aus Benzol bei 165°C schmolz; Ausbeute: 56,60/o der Theorie. Example 1 1- (3'-Chloro-4'-methylphenyl) -4- (p- [tert-amyl] -phenoxyhexamethylene) -piperazine A mixture of 10.6 g (0.05 mol) of 1- (3'-chloro-4'-methylphenyl) piperazine, 16.4 g (0.05 mol) p- (tert-amyl) phenoxyhexamethylene bromide, 10.1 g (0.10 mol) triethylamine and 125 ml of toluene were refluxed overnight. The reaction mixture was then filtered and the filtrate concentrated. The residue was dissolved in ether dissolved and treated with alcoholic hydrogen chloride to give the desired reaction product precipitated in the form of its hydrochloride, which after recrystallization from benzene melted at 165 ° C; Yield: 56.60 / o of theory.
Die benötigten Ausgangsstoffe wurden auf folgende Weise hergestellt: a) 1-(3'-Chlor-4'-methylphenyl)-piperazin Einem eiskalten Gemisch von 47,3 g (0,45 Mol) Diäthanolamin und 56,6 g (0,4 Mol) 3-Chlor4-aminotoluol wurden langsam unter Rühren 100 ml Bromwasserstoffsäure zugegeben. Das Gemisch wurde dann 8 Stunden auf 200°C erhitzt, wobei das entstandene Wasser kontinuierlich durch Destillation entfernt wurde. Die so entstandene feste Masse wurde in Wasser gelöst und die Lösung mit 40%igem wäßrigem Natriumhydroxyd alkalisch gestellt. Das wäßrige Gemisch wurde mit Benzol behandelt, die Benzolschicht getrocknet und bei vermindertem Druck fraktioniert destilliert, wobei das gesuchte 1-(3'-Chlor-4'-methylphenyl)-piperazin erhalten wurde, das bei 150 bis 156°C/2 mm siedete und einen Brechungsindex nD25 1,5900 hatte. b) (p-tert.-Amyl)-phenoxy-hexamethylen-bromid Einem zum Sieden erhitzten Gemisch von 262,4 g (1,6 Mol) p-(tert.-Amyl)-phenol und 488 g (2,0 Mol) Hexamethylendibromid wurde langsam unter Rühren eine Lösung von 64 g (1,6 Mol) Natriumhydroxyd in 11 Wasser zugegeben. Nach Beendigung der Reaktion wurden die niedrigsiedenden Fraktionen abdestilliert und der Rückstand fraktioniert destilliert, wobei das gesuchte Bromid erhalten wurde, das bei 189 bis 194°C/2 mm siedete und einen Brechungsindex n205 1,5174 zeigte. The required raw materials were produced in the following way: a) 1- (3'-Chloro-4'-methylphenyl) -piperazine An ice-cold mixture of 47.3 g (0.45 Mol) diethanolamine and 56.6 g (0.4 mol) 3-chloro-4-aminotoluene were slowly taking 100 ml of hydrobromic acid are added with stirring. The mixture was then left on for 8 hours Heated to 200 ° C, the resulting water is continuously removed by distillation became. The resulting solid mass was dissolved in water and the solution with 40% aqueous sodium hydroxide made alkaline. The aqueous mixture was with Treated benzene, dried the benzene layer and fractionated under reduced pressure distilled, the sought 1- (3'-chloro-4'-methylphenyl) piperazine being obtained which boiled at 150 to 156 ° C / 2 mm and had a refractive index nD25 1.5900. b) (p-tert-amyl) -phenoxy-hexamethylene-bromide A mixture heated to the boil of 262.4 g (1.6 moles) of p- (tert-amyl) phenol and 488 g (2.0 moles) of hexamethylene dibromide a solution of 64 g (1.6 mol) of sodium hydroxide in 11 was slowly added with stirring Water added. After the completion of the reaction, the low-boiling fractions became distilled off and the residue fractionally distilled, the bromide being sought which boiled at 189 to 194 ° C / 2 mm and had a refractive index n205 1.5174 showed.
