The present invention relates to macrocylic compounds and compositions containing said compounds acting as kinase inhibitors, in particular as inhibitors of FLT3 (FMS-Related Tyrosine kinase 3). Moreover, the present invention provides processes for the preparation of the disclosed compounds, as well as methods of using them, for instance as a medicine, in particular for the treatment of cell proliferative disorders, such as cancer.

the development of selective CK2 inhibitors. Optimization of this scaffold, which included macrocyclization, led to IC20 (31) a compound that displayed high in vitro potency for CK2 (KD = 12 nM) and exclusive selectivity for CK2. X-ray analysis revealed a canonical type-I binding mode for IC20 (31). However, the polar carboxylic acid moiety that is shared by many CK2 inhibitors including silmitasertib
酪蛋白激酶2(CK2)是组成型表达的丝氨酸/苏氨酸激酶,具有大量的细胞底物。因此,CK2已经与多种调节功能相关,并且CK2的失调与疾病发展特别是与癌症有关。疾病病理学的广泛含义使CK2成为有吸引力的靶标。迄今为止,最先进的CK2抑制剂是silmitasertib,尽管已描述了silmitasertib的多个脱靶靶标,但已在临床试验中研究了silmitasertib。为了确定CK2抑制在癌症,其他疾病和正常生理中的作用,非常需要选择性CK2抑制剂的开发。在这项研究中,我们探索了吡唑并[1,5- a]嘧啶铰链结合部分用于开发选择性CK2抑制剂。该支架的优化(包括大环化)导致产生IC20(31),该化合物对CK2表现出较高的体外效力(K D = 12 nM),对CK2的排他选择性更高。X射线分析揭示了IC20的典型I型结合模式(31)。但是,效力需要许多CK2抑制剂(包括silmitasert
