Colony stimulating factor 1 receptor kinase (CSF1R) is a well validated molecular target for anticancer drug discovery. Herein, we report the design, synthesis, and structure–activity relationship study of 2-oxo-3,4-dihydropyrimido[4,5-d]pyrimidines as new orally bioavailable CSF1R inhibitors. One of the most promising compounds, 3bw, potently inhibits CSF1R kinase with an IC50 value of 3.0 nM, while
集落刺激因子1受体激酶(CSF1R)是抗癌药物发现的一种经过充分验证的分子靶标。在这里,我们报告2-氧代-3,4-二氢嘧啶[4,5- d ]嘧啶类药物作为新型口服生物利用的CSF1R抑制剂的设计,合成和构效关系研究。最有前途的化合物之一3bw可以有效抑制CSF1R激酶,IC 50值为3.0 nM,而对结构相关的表皮生长因子受体(EGFR)和其他激酶的抑制作用较小。3bw的激酶抑制通过RAW264.7巨噬细胞中的蛋白质印迹分析进一步证实了这一点。该分子还有效阻断巨噬细胞浸润,消除巨噬细胞的致瘤作用,并表现出合理的药代动力学特征。化合物3bw可以用作未来抗癌药物发现的新的有价值的先导化合物。
