- the concentration of cytokines was determined in the supernatant by means of commercially available ELISA kits.
- glucocorticoid therapy One of the most common adverse effects of glucocorticoid therapy is the so-called "steroid diabetes" [cf. Hatz, HJ, Glucocorticoide: Immunological Foundations, Pharmacology and Therapy Guidelines,ticianliche Verlagsgesellschaft mbH, Stuttgart, 1998].
- the reason for this is the stimulation of gluconeogenesis in the liver by induction of the responsible enzymes and by free amino acids, which arise from the degradation of proteins (catabolic effect of glucocorticoids).
- a key enzyme of catabolic metabolism in the liver is tyrosine aminotransferase (TAT). The activity of this enzyme can be determined photometrically from liver homogenates and represents a good measure of the undesired metabolic effects of the glucocorticoids.

Biologische AktivitätBiological activity
Die anti-inflammatorische Wirkung der Verbindungen der allgemeinen Formel (I) wird im Tierexperiment durch Testen in der Crotonöl-induzierten Entzündung in der Ratte und der Maus getestet (J. Exp. Med. (1995), 182, 99-108). Hierzu wird den Tieren Crotonöl in ethanolischer Lösung topisch auf die Ohren appliziert. Die Testsubstanzen werden gleichzeitig oder zwei Stunden vor dem Crotonöl ebenfalls topisch oder systemisch appliziert. Nach 16-24 Stunden werden das Ohrgewicht als Maß für das entzündliche Ödem, die Peroxidaseaktivität als Maß für die Einwanderungen von Granulozyten und die Elastaseaktivität als Maß für die Einwanderung von neutrophilen Granulozyten gemessen. Die Verbindungen der allgemeinen Formel (I) hemmen in diesem Test sowohl nach topischer, als auch nach systemischer Applikation die drei oben genannten Entzündungsparameter.The anti-inflammatory activity of the compounds of general formula (I) is tested in animal experiments by testing in croton oil-induced inflammation in rat and mouse (J. Exp. Med. (1995), 182, 99-108). For this purpose, the animals are topically applied croton oil in ethanolic solution to the ears. The test substances are also applied topically or systemically simultaneously or two hours before the croton oil. After 16-24 hours, ear weights are measured as a measure of inflammatory edema, peroxidase activity as a measure of granulocytic immigration, and elastase activity as a measure of neutrophil granulocyte immigration. The compounds of the general formula (I) inhibit the three abovementioned inflammatory parameters in this test both after topical and after systemic administration.
Die Bindung der Substanzen an den Glucocorticoid-Rezeptor (GR) und weitere Steroidhormon-Rezeptoren (Mineralcorticoid-Rezeptor (MR), Progesteron-Rezeptor
(PR) und Androgen-Rezeptor (AR)) wird mit Hilfe rekombinant hergestellter Rezeptoren überprüft. Cytosolpräparationen von Sf9 Zellen, die mit rekombinanten Baculoviren, die für den GR kodieren, infiziert worden waren, werden für die Bindungsuntersuchungen eingesetzt. Im Vergleich zur Bezugssubstanz [3H]- Dexamethason zeigen die Substanzen eine hohe Affinität zum GR. So wurde für die Verbindung aus Beispiel 1 ein IC50(GR) = 20 nM und IC5o(PR) > 1 μM und für die Verbindung aus Beispiel 2 ein ICso(GR) = 30 nM und ICso(PR) > 1 μM gemessen.The binding of the substances to the glucocorticoid receptor (GR) and other steroid hormone receptors (mineral corticoid receptor (MR), progesterone receptor (PR) and androgen receptor (AR)) is checked using recombinant receptors. Cytosol preparations of Sf9 cells infected with recombinant baculoviruses encoding the GR are used for the binding assays. In comparison with the reference substance [ 3 H] -dexamethasone, the substances show a high affinity for GR. Thus, for the compound of Example 1, an IC 50 (GR) = 20 nM and IC 5 o (PR)> 1 μM and for the compound from Example 2 an IC 50 (GR) = 30 nM and IC 50 (PR)> 1 μM measured.
Als wesentlicher, molekularer Mechanismus für die anti-inflammatorische Wirkung von Glucocorticoiden wird die durch den GR vermittelte Hemmung der Transkription von Cytokinen, Adhäsionsmolekülen, Enzymen und anderer pro - inflammatorischen Faktoren angesehen. Diese Hemmung wird durch eine Interaktion des GR mit anderen Transkriptionsfaktoren, z.B. AP-1 und NF-kappa-B, bewirkt (zur Übersicht siehe Cato ACB and Wade E, BioEssays 18, 371-378 1996).As a major molecular mechanism for the anti-inflammatory effect of glucocorticoids, the GR-mediated inhibition of transcription of cytokines, adhesion molecules, enzymes, and other pro-inflammatory factors is considered. This inhibition is mediated by an interaction of the GR with other transcription factors, e.g. AP-1 and NF-kappa-B (for review see Cato ACB and Wade E, BioEssays 18, 371-378 1996).
Die erfindungsgemäßen Verbindungen der allgemeinen Formel (I) hemmen die durch Lipopolysaccharid (LPS) ausgelöste Sekretion des Cytokins IL-8 in der menschlichen Monozytenzelline THP-1. Die Konzentration der Cytokine wurde im Überstand mittels kommerziell erhältlicher ELISA-Kits bestimmt.The compounds of the general formula (I) according to the invention inhibit the lipopolysaccharide (LPS) -derived secretion of the cytokine IL-8 in the human monocyte cell THP-1. The concentration of cytokines was determined in the supernatant by means of commercially available ELISA kits.
Eine der häufigsten unerwünschten Wirkungen einer Glucocorticoid-Therapie ist der sogenannte "Steroiddiabetes" [vgl. Hatz, HJ, Glucocorticoide: Immunologische Grundlagen, Pharmakologie und Therapierichtlinien, Wissenschaftliche Verlagsgesellschaft mbH, Stuttgart, 1998]. Ursache hierfür ist die Stimulation der Gluconeogenese in der Leber durch Induktion der hierfür verantwortlichen Enzyme und durch freie Aminosäuren, die aus dem Abbau von Proteinen (katabole Wirkung der Glucocorticoide) entstehen. Ein Schlüsselenzym des katabolen Stoffwechsels in der Leber ist die Tyrosinaminotransferase (TAT). Die Aktivität dieses Enzyms kann photometrisch aus Leberhomogenaten bestimmt werden und stellt ein gutes Maß für die unerwünschten metabolischen Wirkungen der Glucocorticoide dar. Zur Messung der TAT-Induktion werden die Tiere 8 Stunden nach Gabe der Testsubstanzen getötet, die Leber entnommen und die TAT - Aktivität im Homogenat gemessen. Die Verbindungen der allgemeinen Formel (I) induzieren in diesem Test in Dosen, in
denen sie anti-inflammatorisch wirksam sind, nicht oder nur in geringem Maße die Tyrosinaminotransferase.One of the most common adverse effects of glucocorticoid therapy is the so-called "steroid diabetes" [cf. Hatz, HJ, Glucocorticoide: Immunological Foundations, Pharmacology and Therapy Guidelines, Wissenschaftliche Verlagsgesellschaft mbH, Stuttgart, 1998]. The reason for this is the stimulation of gluconeogenesis in the liver by induction of the responsible enzymes and by free amino acids, which arise from the degradation of proteins (catabolic effect of glucocorticoids). A key enzyme of catabolic metabolism in the liver is tyrosine aminotransferase (TAT). The activity of this enzyme can be determined photometrically from liver homogenates and represents a good measure of the undesired metabolic effects of the glucocorticoids. To measure the TAT induction, the animals are sacrificed 8 hours after administration of the test substances, the liver removed and the TAT activity in the Homogenate measured. The compounds of general formula (I) induce, in doses, in this test which they are anti-inflammatory, not or only to a limited extent tyrosine aminotransferase.
