The present invention relates to 1 H-pyrazolo[3,4-b]pyridine compounds of the formula (I) in which R1, R2, R3 and R4 are defined as indicated below. The compounds of the formula I are protein kinase C (PKC) inhibitors, and are useful for the treatment of diseases associated with diabetes and diabetic complications, such as, diabetic nephropathy, diabetic neuropathy and diabetic retinopathy, for example. The invention furthermore relates to the use of compounds of the formula, in particular as active ingredients in pharmaceuticals, and pharmaceutical compositions comprising them.
Some structural and biochemical characteristics of polyamineoxidase (PAO) purified from maize shoots have been examined. The enzyme has only alanine as N-terminal amino acid and its N-terminal sequence shows a significant degree of homology with tryptophan 2-monooxygenase from Pseudomonas syringae pv. savastanoi. The pH optimum for the stability of the native enzyme is 5, similar to that of the barley
已经检查了从玉米芽中纯化的多胺氧化酶 (PAO) 的一些结构和生化特征。该酶仅具有丙氨酸作为 N 端氨基酸,其 N 端序列与来自丁香假单胞菌的色氨酸 2-单加氧酶具有显着的同源性。萨瓦斯塔诺伊 天然酶稳定性的最适 pH 值为 5,类似于大麦叶酶的 pH 值。量热分析显示在 pH 6 时 Tm 为 49.8 度的单个双态转变。在 pH 值为 5 时,热稳定性提高了 14 度以上。胺氧化产物 delta 1-吡咯啉和 diazabicyclononane,是 PAO 活性的竞争性抑制剂(表观 Ki = 400 和 100 microM)。此外,这些化合物提高了酶的热稳定性。N1-乙酰精胺,
