Description
Verfahren zur Herstellung von Derivaten des Naphthalin-1,4,5,8-tetracarbonsäurediimids Es wurde gefunden, daß Derivate des Naphthalin-1,4,5,8-tetracarbonsäurediimids der allgemeinen Formel in der R1 ein Wasserstoffatom, eine Methylgruppe oder eine Dialkylaminoalkylgruppe und R2 ein Wasserstoffatom, eine Methylgruppe, eine Dialkylaminoalkylgruppe oder den Acylrest der Isonicotinsäure bedeutet oder R1 und R2 zusammen eine gegebenenfalls durch ein Sauerstoff- oder Schwefelatom oder eine Alkyliminogruppe mit 1 bis 4 Kohlenstoffatomen unterbrochene Alkylengruppe darstellen, gute Wirkung gegen Tuberkulose und Amöben-, Lamblien- und Oxyuren-Infektionen besitzen.Process for the preparation of derivatives of naphthalene-1,4,5,8-tetracarboxylic acid diimide It has been found that derivatives of naphthalene-1,4,5,8-tetracarboxylic acid diimide of the general formula in which R1 is a hydrogen atom, a methyl group or a dialkylaminoalkyl group and R2 is a hydrogen atom, a methyl group, a dialkylaminoalkyl group or the acyl radical of isonicotinic acid, or R1 and R2 together are an alkylene group optionally interrupted by an oxygen or sulfur atom or an alkylimino group with 1 to 4 carbon atoms represent, have a good effect against tuberculosis and amoebic, lamblia and oxyuric infections.
Die Verbindungen beeinflussen als solche oder in Form ihrer Salze mit nicht toxischen anorganischen oder organischen Säuren die genannten Infektionen günstig. Im Vergleich dazu sind die bekannten nicht basischen Imide der Naphthalin- 1 ,4,5,8-tetracarbonsäure [deutsche Patentschrift 552 760; Liebigs Ann. d. Chem., 531, S. 1 (1937); Helv. chim. acta, 21, 5. 1466 (1938); USA.-Patentschrift 2914531] unwirksam. The compounds affect as such or in the form of their salts the infections mentioned with non-toxic inorganic or organic acids cheap. In comparison, the well-known non-basic imides of the naphthalene 1, 4,5,8-tetracarboxylic acid [German patent specification 552 760; Liebigs Ann. d. Chem., 531, p. 1 (1937); Helv. Chim. acta, 21, p. 1466 (1938); U.S. Patent 2914531] ineffective.
Die neuen Verbindungen haben außerdem laxierende Wirkung. Die erfindungsgemäß
erhältlichen Verbindungen zeichnen sich durch eine gute Wirkung gegenüber solchen
Tuberkelbazillen aus, die gegen eine Behandlung durch Isonicotinsäurehydrazid (INH)
und Thiosemicarbazon resistent geworden sind. Sie zeigen auch gegenüber anderen
klinisch bedeutsamen Tuberkulostatika, wie Streptomycin und p-Aminosalicylsäure,
keine Kreuzresistanz. In der folgenden Aufstellung sind die minimalen Hemmkonzentrationen
von verschiedenen Verfahrensprodukten in γ/ml Eimedium, die für eine Unterdrückung
des Wachstums von gegen INH-resistenten Mykobakterien erforderlich waren, im Vergleich
zur Hemmkonzentration des Isonicotinsäurehydrazids aufgeführt. Die Versuche wurden.an
einem Laborstamm (125) durchgeführt, der ursprünglich aus Patientenmaterial isoliert
worden war.
Die Umsetzung wird in Gegenwart eines Lösungsmittels oder in der Schmelze durchgeführt. Als besonders günstig hat sich die Verwendung von Toluol und Xylol als Lösungsmittel erwiesen. Bei der bei Siedetemperatur rasch verlaufenden Reaktion läßt sich das entstehende Wasser durch azeotrope Destillation am Wasserabscheider in einfacher Weise entfernen. The reaction is carried out in the presence of a solvent or in the Melt carried out. The use of toluene has proven to be particularly favorable and xylene proved to be solvents. In the case of the rapidly running at boiling point The resulting water can be reacted by azeotropic distillation on a water separator easily remove.
Beispiel 1 a) 15 g Naphthalin- 1,4,5, 8-tetracarbonsäuredianhydrid werden in 250 ccm Chlorbenzol suspendiert und unter Rühren zum Sieden erwärmt. Man tropft 23 g N,N-Bis-(ß-diäthylaminoäthyl)-hydrazin ein und kocht 1 Stunde unter Rückfluß. Nach dem Erkalten wird mit verdünnter Essigsäure extrahiert, die essigsauren Auszüge alkalisch gestellt und mit Chloroform ausgeschüttelt. Nach dem Trocknen und Eindampfen hinterbleibt ein Ol, das nach einiger Zeit kristallisiert. Example 1 a) 15 g of naphthalene-1,4,5,8-tetracarboxylic acid dianhydride are suspended in 250 ccm of chlorobenzene and heated to the boil while stirring. Man drops 23 g of N, N-bis (ß-diethylaminoethyl) hydrazine and boils under for 1 hour Reflux. After cooling, it is extracted with dilute acetic acid, the acetic acid Extracts made alkaline and extracted with chloroform. After drying and evaporation, an oil remains which crystallizes after a while.
Zur Charakterisierung der erhaltenen Verbindung fällt man aus Äthanol das Maleinat aus, das sich aus Athanol umkristallisieren läßt. Man erhält 14 g N,N'-Bis-[bis-(ß-diäthylaminoäthyl)-amino]-naphthalin-1,4,5,8-tetracarbonsäurediimid-maleinat; F. 184 bis 186"C. b) In analoger Weise erhält man N,N'-Bis-[ß-diäthylaminoäthylamino] - naphthalin - 1,4,5,8 - tetracarbonsäurediimid; F. 187 bis 188"C. To characterize the compound obtained, it is precipitated from ethanol the maleate, which can be recrystallized from ethanol. 14 g of N, N'-bis [bis (ß-diethylaminoethyl) amino] naphthalene-1,4,5,8-tetracarboxylic acid diimide maleate are obtained; F. 184 to 186 "C. b) N, N'-bis [ß-diethylaminoäthylamino] is obtained in an analogous manner - naphthalene - 1,4,5,8 - tetracarboxylic acid diimide; F. 187 to 188 "C.
Beispiel 2 13,4 g Naphthalin- 1,4, 5,8-tetracarbonsäuredianhydrid werden in 80 ccm Dimethylformamid auf 100"C erwärmt. Man tropft unter Rühren langsam 6 ccm Hydrazinhydrat ein und rührt weitere 2 Stunden bei Zimmertemperatur. Nach dem Erkalten wird abgesaugt, der Rückstand mit Äthanol gewaschen, anschließend mit der zehnfachen Menge gesättigter Sodalösung auf dem Wasserbad erwärmt, wieder abfiltriert und neutral gewaschen. Nach dem Trocknen erhält man 10 g N,N'-Diaminonaphthalin-1,4,5,8-tetracarbonsäurediimid, das oberhalb 250"C schmilzt. Example 2 13.4 g of naphthalene-1,4,5,8-tetracarboxylic acid dianhydride are heated to 100 ° C. in 80 cc of dimethylformamide. It is slowly added dropwise with stirring 6 cc hydrazine hydrate and stir for a further 2 hours at room temperature. To the cooling is suctioned off, the residue washed with ethanol, then with ten times the amount of saturated soda solution heated on a water bath, filtered off again and washed neutral. After drying, 10 g of N, N'-diaminonaphthalene-1,4,5,8-tetracarboxylic acid diimide are obtained, that melts above 250 "C.
Beispiel 3 21 g Naphthalin- 1 ,4,5,8-tetracarbonsäuredianhydiid und 27 g Isonicotinsäurehydrazid werden gemischt und etwa 1 Stunde auf 260"C zum Schmelzen erhitzt. Nach dem Erkalten wird in Dimethylformamid gelöst und durch Eintropfen in Äthanol ausgefällt; man erhält 20 g N,N'-Bis-(isonicotinoylamino) - naphthalin - 1,4,5,8- tetracarbonsäurediimid; E. >360°C. Example 3 21 g of naphthalene-1, 4,5,8-tetracarboxylic acid dianhydride and 27 g of isonicotinic hydrazide are mixed and allowed to melt at 260 "C for about 1 hour heated. After cooling, it is dissolved in dimethylformamide and added dropwise precipitated in ethanol; 20 g of N, N'-bis (isonicotinoylamino) naphthalene are obtained - 1,4,5,8-tetracarboxylic acid diimide; E.> 360 ° C.
