  N-Phenyl-4-pyrazolo[1,5-b]pyridazin-3-ylpyrimidin-2-amines as Potent and Selective Inhibitors of Glycogen Synthase Kinase 3 with Good Cellular Efficacy

  摘要：

  Glycogen synthase kinase 3 regulates glycogen synthase, the rate-determining enzyme for glycogen synthesis. Liver and muscle glycogen synthesis is defective in type 2 diabetics, resulting in elevated plasma glucose levels. Inhibition of GSK-3 could potentially be an effective method to control plasma glucose levels in type 2 diabetics. Structure-activity studies on a N-phenyl-4-pyrazolo[1,5-b]pyridazin-3-ylpyrimidin-2-amine series have led to the identification of potent and selective compounds with good cellular efficacy. Molecular modeling studies have given insights into the mode of binding of these inhibitors. Since the initial leads were also potent inhibitors of CDK-2/CDK-4, an extensive SAR was performed at various positions of the pyrazolo[1,5-b]pyridazin core to afford potent GSK-3 inhibitors that were highly selective over CDK-2. In addition, these inhibitors also exhibited very good cell efficacy and functional response. A representative example was shown to have good oral exposure levels, extending their utility in an in vivo setting. These inhibitors provide a viable lead series in the discovery of new therapies for the treatment of type 2 diabetes.

  选择性和配体高效的 DYRK 抑制剂的发现和表征

  摘要：

  双特异性酪氨酸调节激酶​​ 1A (DYRK1A) 调节大脑发育过程中神经元祖细胞的增殖和分化。因此，DYRK1A 作为治疗神经退行性疾病（包括阿尔茨海默病（AD）和唐氏综合症）的靶标引起了人们的兴趣。最近，DYRK1A 的抑制已被研究为糖尿病的潜在治疗方法，而 DYRK1A 作为细胞周期介质的作用引起了人们对肿瘤适应症的兴趣。构效关系（SAR）分析与高分辨率X射线晶体学相结合，产生了一系列吡唑并[1,5- b ]哒嗪抑制剂，具有优异的配体效率、良好的理化性质以及对其他药物的高度选择性。激酶。化合物11表现出良好的渗透性和细胞活性，且无需 P-糖蛋白，从而扩展了11在体内环境中的效用。这些吡唑并[1,5- b ]哒嗪是发现治疗与 DYRK1A 功能相关疾病的新疗法的可行的先导系列。
