Description
Die Erfindung betrifft den Gegenstand der Ansprüche. The invention relates to the subject matter of the claims.
Das biologische Profil dieser Verbindungen ist das folgende:The biological profile of these compounds is as follows:
Die Verbindungen inhibieren diejenigen Immunoreaktionen, die als zellbedingte, verzögerte Hypersensitivitäten eingeordnet werden. Diese letzteren schließen ein die späten, sekundären Migrationsläsionen bei Ratten, denen Freundsches Adjuvans injiziert wurde in Übereinstimmung mit den Techniken, wie sie in Brit. J. Pharmacol., 21, S. 127 — 136 (1962), und 24, S. 632 bis 640 (1965), beschrieben werden; die sensibilisierte Reaktion auf bakterielles Endotoxin, wie es in dem Milz-Zelltest gezeigt wird, vgl. lerne et. al., Cell-bound Antibodies. V/istar Institute Press, 1963, S. 109; die Abstoßung von Hauttransplantat bei Mäusen und Ratten und die Abstoßung von Brustdrüsengewebe bei Ratten, vgl. B i 11 i η g h a m, Transplantation of Cells and Tissues, Wistar Institute Press, 1961, S. 1; Kontakt und Protein-Hypersensitivitäten bei Meerschweinchen, Kaninchen und Ratten, vgl. Uhr, Physiol. Rev., 46, S. 359—419. Die erfindungsgemäßen Verbindungen zeigten in einem Dosisbereich von ca. 1 bis 1000 mg/kg, insbesondere bei 25 bis 100 mg/kg drei- bis viermal täglich oral oder durch Injektion verabreicht, abhängig von dem verwendeten Tier, Wirksamkeit, indem sie die verschiedenen Erscheinungsformen verzögerter Hypersensitivität der Immunoreaktion unterdrücken.The compounds inhibit those immunoreactions that are known as cell-related, delayed hypersensitivities be classified. These latter include the late secondary migratory lesions Rats injected with Freund's adjuvant in accordance with the techniques set out in Brit. J. Pharmacol., 21, pp. 127-136 (1962) and 24, pp. 632-640 (1965); the sensitized response to bacterial endotoxin, as in the spleen cell test is shown, see learn et. al., Cell-bound Antibodies. V / istar Institute Press, 1963, p. 109; the rejection of skin grafts in mice and rats and the Rejection of mammary gland tissue in rats, see B i 11 i η g h a m, Transplantation of Cells and Tissues, Wistar Institute Press, 1961, p. 1; Contact and protein hypersensitivities in guinea pigs, rabbits and rats, see Uhr, Physiol. Rev., 46, pp. 359-419. The compounds according to the invention showed in a dose range of approx. 1 to 1000 mg / kg, in particular at 25 to 100 mg / kg three to four times Administered orally or by injection daily, depending on the animal used, efficacy by the suppress various manifestations of delayed immunoreaction hypersensitivity.
Zu den verzögerten Hypersensitivitäten der Immunoreaktionen, bei denen die erfindungsgemäßen Verbindungen verwendet werden können, gehören beispielsweise rheumatische Arthritis, ulcerative Colitis, Allergien. Haut- und Organ-Transplantationen, systemischer Lupus, glomerolare Nephritis und ähnliche. Was die Toxizität betrifft, so haben die erfindungsgemäßen Verbindungen besonders niedrige Toxizität, beispielsweise treten bei oraler Gabe von 5 g/kg oder bei intravenöser Injektion von 1 g/kg an Mäusen keine Todesfälle auf.On the delayed hypersensitivities of the immunoreactions, in which the compounds of the invention can be used include, for example rheumatoid arthritis, ulcerative colitis, allergies. Skin and organ transplants, systemic Lupus, glomerolar nephritis and the like. As for toxicity, those of the present invention have Compounds particularly low toxicity, for example, occur with oral administration of 5 g / kg or intravenous injection of 1 g / kg into mice did not result in any deaths.
6-Mercaptopurin ist die auf diesem Gebiet bisher meistverwendete Verbindung, wie sich z. B. aus Römpps Chemie-Lexikon, 7. Aufl., 1972, S. 2114, ergibt.6-mercaptopurine is the most widely used compound in this field to date, as is e.g. B. from Römpps Chemie-Lexikon, 7th ed., 1972, p. 2114, results.
Es kann aber festgestellt werden, daß das Überleben von Fremdtransplantaten wesentlich durch eine chemisehe Beeinflussung durch die erfindungsgemäßen Verbindungen verlängert wird, ohne daß die Antikörperbildung unterdrückt wird. Die erfindungsgemäßen Verbindungen waren nicht weniger effektiv bei der Ausdehnung der Lebensdauer der Transplantate als 6-Mercaptopurin, aber ungleich diesem unterdrückte es unter den gleichen Bedingungen nicht die Antikcrperproduktion. Es ergab sich auch, daß die Immunisierungsdauer, d. h. die Überlebensdauer, von Transplantaten bei den erfindungsgemäßen Verbindungen größer war als bei 6-Mercaptopurin. Außerdem ist die Toxizität etwa um das 7fache niedriger als bei 6-Mercaptopurin.It can be stated, however, that the survival of foreign transplants is essentially due to a chemical marriage The influence of the compounds according to the invention is prolonged without the formation of antibodies is suppressed. The compounds of the present invention were no less effective in this Extending the life of the grafts as 6-mercaptopurine, but unlike that suppressed it antibody production does not occur under the same conditions. It was also found that the duration of immunization, i.e. H. the survival time, of transplants the compounds according to the invention was greater than that of 6-mercaptopurine. Besides, the toxicity is about 7 times lower than 6-mercaptopurine.
Um die Verbindungen zu verwenden, können sie mit inerten pharmazeutischen Trägern, wie Laktose, Mannitol, Stärke, verdünnt werden und in Dosiseinheitsformen, wie Tabletten, Kapseln und ähnliche geformt werden. Für die parenterale Verabreichung können diese Verbindungen mit einem inerten, parentalverträglichen Träger, wie Wasser, Salzlösung, Sesamöl und ähnliche, formuliert werden. Diese verschiedenen pharmazeutischen Dosiseinheitsformen werden nach bekannten pharmazeutischen Methoden zusammengestellt. To use the compounds, they can be mixed with inert pharmaceutical carriers such as lactose, mannitol, Starch, can be diluted and formed into unit dosage forms such as tablets, capsules, and the like will. For parenteral administration, these compounds can be mixed with an inert, parentally compatible Carriers such as water, saline, sesame oil and the like can be formulated. These different Pharmaceutical unit dosage forms are composed according to known pharmaceutical methods.
Gemäß der Erfindung wird die freie Verbindung hergestellt, indem ein niedermolekularer Ester der Picolinsäure mit Dimethylsulfoxyd in Gegenwart einer starken Base, wie Natriumamid, Natriumhydrid oder Kalium-t-butylat, umgesetzt wird.
