Die hier verwendeten Ausdrücke «C1_4» und «C2_4» bezeichnen Gruppen mit 1-4 bzw. 2-4 Kohlenstoffatomen. AI-kyl-, Alkoxy-, Alkenyl- und Alkenyloxygruppen können geradkettig oder verzweigt sein und enthalten zweckmässig eine niedere C-Anzahl. Beispiele solcher Gruppen sind Methyl, Äthyl, Propyl, Isopropyl, tert.-Butyl, Methoxy, Äthoxy, Propoxy und Isopropoxy; Vinyl, Allyl, Vinyloxy und Allyl-oxy. The terms “C1_4” and “C2_4” used here refer to groups with 1-4 and 2-4 carbon atoms. Al-kyl, alkoxy, alkenyl and alkenyloxy groups can be straight-chain or branched and suitably contain a lower C number. Examples of such groups are methyl, ethyl, propyl, isopropyl, tert-butyl, methoxy, ethoxy, propoxy and isopropoxy; Vinyl, allyl, vinyloxy and allyloxy.
Beispiele von hydrolytisch in eine Amino- oder R3-NH--Gruppe überführbaren Resten R4, R5 und R6 sind -NHR7, -N=CHR, -N=C(R)2, -N=CHOR:i, -NHCOOR3, -NR3-COOR3, -NR3R7 und Phthalimido, wobei R Alkyl, Alkenyl oder Aryl darstellt, R8 die oben angegebene Bedeutung hat und R7 der Acylrest einer vorzugsweise niederen aliphatischen Carbonsäure oder einer Sulfonsäure darstellt. Besonders geeignete hydrolysierbare Gruppen R° sind Formylamino, Acet-amino, Phthalimido oder Carbobenzoxyamino. Examples of radicals R4, R5 and R6 which can be converted hydrolytically into an amino or R3-NH group are -NHR7, -N = CHR, -N = C (R) 2, -N = CHOR: i, -NHCOOR3, - NR3-COOR3, -NR3R7 and phthalimido, where R represents alkyl, alkenyl or aryl, R8 has the meaning given above and R7 represents the acyl radical of a preferably lower aliphatic carboxylic acid or a sulfonic acid. Particularly suitable hydrolyzable groups R ° are formylamino, acetamino, phthalimido or carbobenzoxyamino.
Die Hydrolyse dieser Gruppen wird zweckmässig in saurem Medium, z.B. mit wässrigen oder wässrig-alkoholischen Mineralsäuren, wie Salzsäure, durchgeführt. Alkalisch hydrolysierbare Gruppen sind die Gruppen -NR3COOR3, -NH-COOR3 und -NHCHO. Die alkalische Hydrolyse kann mit wässrigem oder wässrig-alkoholischem (methanolischem) Alkali erfolgen. Die Phthalimidogruppe kann, vorzugsweise, durch Hydrazinolyse in die Aminogruppe umgewandelt werden. The hydrolysis of these groups is conveniently carried out in an acidic medium, e.g. with aqueous or aqueous-alcoholic mineral acids, such as hydrochloric acid. Alkaline hydrolyzable groups are the groups -NR3COOR3, -NH-COOR3 and -NHCHO. The alkaline hydrolysis can be carried out with aqueous or aqueous-alcoholic (methanolic) alkali. The phthalimido group can, preferably, be converted to the amino group by hydrazinolysis.
Für die Herstellung von Säureadditionssalzen, insbesondere von in pharmazeutischen Präparaten brauchbaren Salzen, kommen die üblicherweise für diesen Zweck verwendeten anorganischen Säuren, wie Salzsäure, Schwefelsäure, Phosphorsäure, etc. oder organischen Säuren, wie Ameisensäure, Essigsäure, Bernsteinsäure, Milchsäure, Citronensäure, Maleinsäure, Fumarsäure, Weinsäure, Methansulfonsäure, p-Toluolsulfonsäure etc. in Betracht. For the production of acid addition salts, in particular salts which can be used in pharmaceutical preparations, the inorganic acids usually used for this purpose, such as hydrochloric acid, sulfuric acid, phosphoric acid, etc., or organic acids, such as formic acid, acetic acid, succinic acid, lactic acid, citric acid, maleic acid, Fumaric acid, tartaric acid, methanesulfonic acid, p-toluenesulfonic acid etc. into consideration.
Die Verbindungen der Formel I und ihre Salze sind antibakteriell wirksam. Sie hemmen die bakterielle Dihydro-folat-Reduktase und potenzieren die antibakterielle Wirkung von Sulfonamiden, wie z.B. Sulfisoxazol, Sulfadimethoxin, Sulfamethoxazol, 4-Sulfanilamido-5,6-dimethoxy-pyrimidin, 2-SulfaniIamido-4,5-dimethyl-pyrimidin oder Sulfachinoxalin, Sulfadiazin, Sulfamonomethoxin, 2-SulfaniIamido-4,5-dime-thyl-isoxazol und anderen Inhibitoren für Enzyme, die an der Folsäurebiosynthese beteiligt sind, wie z.B. Pteridinderi-vate. The compounds of formula I and their salts are antibacterial. They inhibit the bacterial dihydro-folate reductase and potentiate the antibacterial effect of sulfonamides, e.g. Sulfisoxazole, sulfadimethoxin, sulfamethoxazole, 4-sulfanilamido-5,6-dimethoxy-pyrimidine, 2-sulfaniIamido-4,5-dimethyl-pyrimidine or sulfachinoxaline, sulfadiazine, sulfamonomethoxine, 2-sulfaniIamido-4,5-dimethyl-isoxazole and other inhibitors for enzymes involved in folic acid biosynthesis, such as Pteridinderi-vate.
Für solche Kombinationen einer oder mehrerer der er-findungsgemässen Verbindungen I mit Sulfonamiden kommt in der Humanmedizin orale, rectale und parenterale Applikation in Frage. Das Verhältnis von Verbindung I zu Sulfonamid kann innerhalb eines weiten Bereiches variieren; es beträgt z.B. zwischen 1:40 (Gewichtsteile) und.5:1 (Gewichtsteil); bevorzugte Verhältnise sind 1:1 bis 1:5. For such combinations of one or more of the compounds I according to the invention with sulfonamides, oral, rectal and parenteral administration are suitable in human medicine. The ratio of compound I to sulfonamide can vary within a wide range; it is e.g. between 1:40 (parts by weight) and 5: 1 (parts by weight); preferred ratios are 1: 1 to 1: 5.
So kann z.B. eine Tablette 80 mg einer erfindungsgemäs-sen Verbindung I und 400 mg Sulfamethoxazol, eine Kindertablette 20 mg einer erfindungsgemässen Verbindung I und 100 mg Sulfamethoxazol; Sirup (pro 5 ml) 40 mg Verbindung 1 und 200 mg Sulfamethoxazol enthalten. For example, one tablet 80 mg of a compound I according to the invention and 400 mg of sulfamethoxazole, one child's tablet 20 mg of a compound I according to the invention and 100 mg of sulfamethoxazole; Syrup (per 5 ml) contain 40 mg of compound 1 and 200 mg of sulfamethoxazole.
Die Verbindungen der Formel I zeichnen sich durch eine hohe antibakterielle Wirksamkeit bzw. einen ausgeprägten synergistischen Effekt in Kombination mit Sulfonamiden und gute Verträglichkeit aus. The compounds of the formula I are notable for high antibacterial activity or a pronounced synergistic effect in combination with sulfonamides and good tolerance.
