Despite extensive research on small molecule thrombininhibitors for oral application in the past decades, only a single double prodrug with very modest oral bioavailability has reached human therapy as a marketed drug. We have undertaken major efforts to identify neutral, non-prodrug inhibitors. Using a holistic analysis of all available internal data, we were able to build computational models and
The present invention covers 3-oxo-2,6-diphenyl-2,3-dihydropyridazine-4-carboxamide compounds of general formula (I): in which R1, R2, R3, R4, R5 and R6 are as defined herein, methods of preparing said compounds, intermediate compounds useful for preparing said compounds, pharmaceutical compositions and combinations comprising said compounds and the use of said compounds for manufacturing pharmaceutical compositions for the treatment or prophylaxis of diseases, in particular of cancer or conditions with 10 dysregulated immune responses or other disorders associated with aberrant AHR signaling, as a sole agent or in combination with other active ingredients.

formed were easily isolated by gel filtration and cation-exchange chromatography in 60–80% yields. The reaction was accompanied by the intense reductivecleavage of peptide bonds with formation of amino alcohols, but N -deacetylation of hexosamine was completely excluded. The optimal conditions of this reaction were chosen by use of a model glycopeptide, 2-acetamido-4- O -(2-acetamido-2-deoxy-β- d -glucopyranosyl)-1-
摘要从糖蛋白中分离N连接寡糖的一种温和的新方法包括在25m m LiOH-50m m柠檬酸70%溶液中用2 m LiBH 4处理糖蛋白(卵类粘液,黄素蛋白,核糖核酸酶B,血凝素或转铁蛋白)。用叔丁醇水溶液洗涤(5小时,45°),然后用乙酸水溶液水解所得糖基胺。形成的寡糖很容易通过凝胶过滤和阳离子交换色谱分离,产率为60-80%。该反应伴随着肽键的强烈还原性切割和氨基醇的形成,但是己胺的N-脱乙酰化被完全排除。此反应的最佳条件是通过使用模型糖肽选择的,
