From Imidazoles to Pyrimidines: New Inhibitors of Cytokine Release
摘要:
On the basis of model imidazole inhibitors of cytokine release, a series of novel pyridinyl pyrimidine derivatives was prepared and tested on their ability to inhibit the release of tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-beta) from peripheral blood mononuclear cells (PBMC) and human whole blood. In the pyrimidine series, structure-activity relationships (SARs) similar to those of the imidazole series were found, although generally pyrimidine compounds were less potent. Modification of the substituent at the 2 position of the pyrimidine led to the most active compound 14 which inhibited release of TNF-alpha (IC50 = 3.2 muM) and IL-1beta (IC50 = 2.3 muM) from PBMC as effectively as the model imidazole inhibitor ML 3163 (TNF-alpha, IC50 = 3.7 muM; IL-1beta, IC50 = 0-9 muM). Screening in an isolated enzyme assay revealed both imidazole and pyrimidine compounds as inhibitors of p38 MAP (mitogen-activated protein) kinase.

(EN) The present invention addresses substituted pyridyl pyrroles, as well as compositions containing such compounds and methods of treatment. The compounds in the present invention are glucagon antagonists and inhibitors of the biosynthesis and action of TNF-$g(a) and IL1. The compounds block the action of glucagon at its receptors and thereby decrease the levels of plasma glucose. The instant pyrroles are also inhibitors of TNF-$g(a) and IL1 and may be used as antidiabetic agents as well as other cytokine mediated diseases. Cytokine mediated diseases refer to diseases or conditions in which excessive or unregulated production of one or more cytokines occurs. Interleukin-1 (IL-1) and Tumor Necrosis Factor (TNF) are cytokines produced by a variety of cells, which are involved in immunoregulation and other physiological conditions, such as inflammation.(FR) La présente invention concerne des pyrroles de pyridyle substitués, des compositions contenant de tels composés et leur utilisation thérapeutique. Les composés de la présente invention sont des antagoniste du glucagon et des inhibiteurs de la biosynthèse et de l'action du facteur TNF-$g(a) et de l'IL1. Ces composés bloquent l'action du glucagon au niveau de ses récepteurs, ce qui diminue les niveaux de glucose du plasma. Les pyrroles de l'invention, qui sont également des inhibiteurs du facteur TNF-$g(a) et de l'IL1, peuvent servir d'antidiabétiques et contre d'autres affections à médiation des cytokines. L'interleukine-1 (IL-1) et le facteur de nécrose tumorale (TNF) sont des cytokines produites par diverses cellules qui interviennent au niveau de la régulation immunitaire et au niveau d'autres états physiologiques tels que les états inflammatoires.
