pyrazolo[1,5-b]pyridazine inhibitors with excellent ligand efficiencies, good physicochemical properties, and a high degree of selectivity over the kinome. Compound 11 exhibited good permeability and cellular activity without P-glycoprotein liability, extending the utility of 11 in an in vivo setting. These pyrazolo[1,5-b]pyridazines are a viable lead series in the discovery of new therapies for the
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。

Fused pyradazine derivatives, which are useful as CDK inhibitors are described herein. The described invention also includes methods of making such fused pyradazines derivatives as well as methods of using the same in the treatment of hyperproliferative diseases.
The present invention relates generally to inhibitors of the kinases, such as GSK3, and more particularly to fused pyradazine compounds and methods of their use.

A novel series of pyrazolo[1,5-b]pyridazines have been synthesized and identified as cyclin dependant kinase inhibitors potentially useful for the treatment of solid tumors. Modification of the hinge-binding amine or the C(2)- and C(6)-substitutions on the pyrazolopyridazine core provided potent inhibitors of CDK4 and demonstrated enzyme selectivity against VEGFR-2 and GSK3beta.
