4,6-Disubstituted pyrazolo[3,4-d]pyrimidine derivatives were explored as irreversible Bruton's tyrosine kinase (BTK) inhibitors. The structure–activity relationship was established with over 20 derivatives synthesized to determine initial hit compounds, based on activities against BTK enzyme and TMD8 cells. It turned out that introducing 1-acrylamido-4-aminopiperdine (1b) at the C4 position of pyrazolopyrimidine
4,6-二取代的吡唑并[3,4- d ]嘧啶衍生物被探索为不可逆的布鲁顿酪氨酸激酶 (BTK) 抑制剂。基于对 BTK 酶和 TMD8 细胞的活性,用合成的 20 多种衍生物建立了构效关系,以确定初始命中化合物。结果表明,在吡唑并嘧啶的 C4 位引入 1-丙烯酰胺基-4-氨基哌啶 ( 1b ),如5e和 3-丙烯酰胺基苯胺 ( 1j ) 作为 4-位取代基,如9d、10d和10e,体外递送强效酶活性以及基于 TMD8 细胞的细胞毒性。考虑到激酶选择性谱,5e被选择用于使用 TMD8 细胞的鼠异种移植模型进行体内功效研究,其中5e表现出中等的肿瘤生长抑制活性。5e和9d的进一步优化可能会导致临床上有用的化合物来克服 B 细胞介导的血液癌症。
