Abstract
Description
Hypoglykämisch aktive Propandiolaminderivate mit Insulin-ähnlicher Wirkung und deren Verwendung, neue Propandiolaminderivate, diese Substanzen enthaltende pharmazeutische Zubereitungen und ihre Verwendung zur Behandlung von Krankheiten.Hypoglycaemically active propanediolamine derivatives with Insulin-like effects and their use, new ones Propanediolamine derivatives containing these substances pharmaceutical preparations and their use for Treatment of diseases.
Die Behandlung diabetischer Patienten, deren Blutzuckerspiegel gesenkt werden muß, erfolgt in der Therapie entweder durch Injektion von Insulin oder im Falle von Typ II Diabetikern (NIDD: non-insulin-dependent diabetics) z. B. durch orale Verabreichung von endogen Insulin freisetzenden Sulfonylharnstoffen der ersten (z. B. Tolbutamid) oder der zweiten Generation (z. B. Glibenclamid).Treatment of diabetic patients whose Blood sugar levels must be lowered in the Therapy either by injection of insulin or in the event of type II diabetics (NIDD: non-insulin-dependent diabetics) e.g. B. by oral administration of endogenous Insulin releasing sulfonylureas of the first (e.g. Tolbutamide) or the second generation (e.g. Glibenclamide).
Wegen verschiedener Komplikationen der Diabetesbehandlung, wie z. B. Insulinresistenz, Insulinhypersensitivität, Brittle-Diabetes oder Spätversagen der oralen Antidiabetika, ist es wünschenswert, über oral wirksame blutzuckersenkende Präparate zu verfügen, deren Wirkung nicht über Insulin vermittelt wird.Because of various complications of diabetes treatment, such as B. insulin resistance, insulin hypersensitivity, Brittle diabetes or late oral failure Antidiabetic drugs, it is desirable to take over orally effective to have hypoglycemic preparations, their effects is not mediated by insulin.
Insulin ist ein starker Aktivator der Glucoseaufnahme [M. Rodbell, J. Biol. Chem. 239, 375-80 (1964)] bzw. des Glucosetransports [J. M. Olefsky, Biochem. J. 172, 137-145 (1978)] in isolierten Fettzellen. Daher besitzen Substanzen, die in vitro in isolierten Adipozyten die Glucoseaufnahme in Abwesenheit von Insulin erhöhen, "Insulin-ähnliche Wirkung" [J. Gliemann, Diabetologia 3, 382-388 (1967)].Insulin is a strong activator of glucose uptake [M. Rodbell, J. Biol. Chem. 239, 375-80 (1964)] and des Glucose Transport [J. M. Olefsky, Biochem. J. 172, 137-145 (1978)] in isolated fat cells. Therefore own Substances that are isolated in adipocytes in vitro Increase glucose uptake in the absence of insulin "Insulin-like effect" [J. Gliemann, Diabetologia 3, 382-388 (1967)].
In der Literatur sind viele Substanzen mit unterschiedlichsten Strukturen beschrieben worden, die in vitro Insulin-ähnliche Wirkung aufweisen; blutzuckersenkende Effekte in vivo sind aber nur für Natrimvanadat [J. Meyerovich et al. J. Biol. Chem. 262, 6659-6662 (1987)] und für ®Actihaemyl (ein Präparat aus deproteiniertem Kälberblut, W. Bachmann et al. Arzneim. Forsch. 18, 1023-1027 (1968)) beschrieben worden.There are many substances in the literature different structures have been described, which in have an insulin-like effect in vitro; Blood sugar lowering effects in vivo are only for Natrim vanadate [J. Meyerovich et al. J. Biol. Chem. 262, 6659-6662 (1987)] and for ®Actihaemyl (a preparation from deproteinized calf blood, W. Bachmann et al. Pharm. Forsch. 18, 1023-1027 (1968)).
Die vorliegende Erfindung beschreibt Derivate des 3-Aminopropan-1,2-diols, welche die Glucosetransport- aktivierende Wirkung des Insulins in vitro imitieren oder verstärken und die zusätzlich im Tierversuch blutzuckersenkende Wirkung besitzen.The present invention describes derivatives of 3-aminopropane-1,2-diols, which are the glucose transport mimicking the activating effect of insulin in vitro or reinforce and additionally in animal experiments have a hypoglycemic effect.
Es ist bereits bekannt, daß 3-Aryloxy-1-aminopropan-2- olderivate mit Alkyl- oder Aralkylsubstituenten am Amin- Stickstoff an β-adrenerge Rezeptoren binden und diese blockieren. Solche sogenannten β-Blocker sind seit mehr als 20 Jahren zur Behandlung von Bluthochdruck in die Therapie eingeführt. Besonders Substanzen mit Aralkylsubstituenten am Amin-Stickstoff zeigen dabei eine Selektivität für β-Rezeptoren am Herzen (sog. cardioselektive β-Blocker) und sind zur Behandlung von koronaren Herzerkrankungen, z. B. Angina pectoris, geeignet.It is already known that 3-aryloxy-1-aminopropane-2- older derivatives with alkyl or aralkyl substituents on the amine Bind nitrogen to β-adrenergic receptors and these To block. Such so-called β-blockers have been around for more than 20 years to treat hypertension in therapy introduced. Especially substances with aralkyl substituents on amine nitrogen show a selectivity for β-receptors on the heart (so-called cardioselective β-blockers) and are used to treat coronary heart disease, e.g. B. Angina pectoris, suitable.
So beschreiben Hoefle et al. [J. Med. Chem. 18, 148-152 (1975)] Verbindungen der folgenden Struktur als cardioselektive β-Blocker:For example, Hoefle et al. [J. Med. Chem. 18, 148-152 (1975)] Compounds of the following structure as cardioselective β-blockers:
wobei der Ring B mono- oder disubstituiert sein kann. Ähnliche Verbindungen werden z. B. auch in BE-A 79 01 165, BE-A 6 75 967, FR-A 13 94 771 und NL-A 64 10 522 beschrieben.ring B can be mono- or disubstituted. Similar connections are e.g. B. also in BE-A 79 01 165, BE-A 6 75 967, FR-A 13 94 771 and NL-A 64 10 522.
In den Publikationen Kreighbaum et al. [J. Med. Chem. 23, 285-289 (1980)], BE-A 8 68 943 und US-A 42 34 595 werden Verbindungen der folgenden Struktur als antihypertensiv wirksame β-Blocker beschrieben:In the publications Kreighbaum et al. [J. Med. Chem. 23, 285-289 (1980)], BE-A 8 68 943 and US-A 42 34 595 Compounds of the following structure as antihypertensive effective β-blockers described:
Sowohl der Phenylrest als auch der Indolylrest können substituiert sein.Both the phenyl radical and the indolyl radical can be substituted.
In EP-A 65 295 werden β-Blocker mit Thienylresten anstelle von Phenylresten zur Behandlung von Kreislauferkrankungen beschrieben:In EP-A 65 295, β-blockers with thienyl radicals are used instead of phenyl residues for the treatment of circulatory diseases described:
Sowohl der Thienylrest als auch der Indolylrest können bis zu dreifach substituiert sein.Both the thienyl group and the indolyl group can be up to to be triply substituted.
Es wurde nun überraschenderweise gefunden, daß eine Reihe von Verbindungen aus diesen generellen Substanzklassen mit bestimmten Substituenten insulinmimetische Wirkung haben und im Tierexperiment den Blutzuckerspiegel senken. Sie sind daher zur Behandlung der Zuckerkrankheit (Diabetes mellitus) geeignet. Diese Wirkungen sind nicht an die β-Rezeptorbindung gekoppelt.It has now surprisingly been found that a number of compounds from these general substance classes have certain insulin-mimetic effects and lower blood sugar levels in animal experiments. they are therefore used to treat diabetes (diabetes mellitus). These effects are not related to the β-receptor binding coupled.
