kinase responsible for development of various tumor types. Aiming to explore new potent inhibitors, two series of 2,4-disubstituted-7H-pyrrolo[2,3-d]pyrimidine derivatives were designed and synthesized on the base of structure-based design strategy. Biological evaluation indicated that most of these new compounds could potently inhibit FAK kinase, leading to the promising inhibitors against the proliferation
黏着斑激酶(FAK)是负责各种肿瘤类型发展的细胞内非受体酪氨酸激酶。为了探索新的有效抑制剂,在基于结构的设计策略的基础上,设计并合成了两个系列的2,4-二取代-7 H-吡咯并[2,3- d ]嘧啶衍生物。生物学评估表明,这些新化合物中的大多数可以有效抑制FAK激酶,从而导致有希望的抑制剂对抗U-87MG,A-549和MDA-MB-231癌细胞的增殖。其中,优化的化合物18h 在U-87MG,A-549和MDA-MB-231细胞中均有效抑制酶(IC 50 = 19.1 nM),并显示出比TAE-226更强的效力,IC 50分别为0.35、0.24和0.34μM。化合物18h是多靶激酶抑制剂。此外,化合物18h 对正常人细胞株HK2的细胞毒性也较小(IC 50 = 3.72μM)。根据流式细胞术和伤口愈合试验结果,化合物18h有效诱导MDA-MB-231细胞凋亡和G0 / G1期阻滞,并抑制U
