pyrazolo[1,5a]pyrimidine-based FUBP1 inhibitor derived from medium throughput screening, which interferes with the binding of FUBP1 to its single stranded target DNA FUSE. We were able to generate a new class of FUBP1 interfering molecules with in vitro and biological activity. In biophysical assays, we could show that our best inhibitor, compound 6, potently inhibits the binding of FUBP1 to the FUSE sequence
转录调节因子FUSE结合蛋白1(FUBP1)在各种恶性肿瘤中异常上调,通过放松参与细胞周期控制和细胞凋亡调节的关键基因来实现其致癌作用。因此,对该蛋白质的药物抑制将代表令人鼓舞的新型靶向化学疗法。 在这里,我们证明了基于中等通量筛选的吡唑并[1,5 a ]嘧啶基FUBP1抑制剂的鉴定和初步优化,这会干扰FUBP1与其单链靶DNA FUSE的结合。我们能够产生一类具有体外和生物学活性的新型FUBP1干扰分子。在生物物理分析中,我们可以证明我们最好的抑制剂化合物6有效抑制FUBP1与FUSE序列的结合,IC 50值为11.0μM 。此外,肝癌细胞对化合物6的治疗表现出敏感性,导致减少的细胞扩张和诱导细胞死亡。最后,我们提供了对相应SAR前景的见解,从而潜在地提高了效能和细胞功效。
