Fifteen thioxoimidazolidinone derivatives were designed as dual EGFR and CDK2 inhibitors and synthesized following Claisen and Knoevenagel condensation. Derivative 12 showed the best EGFR and CDK2 IC50 giving 0.098 μM and 0.087 μM, respectively, followed by 13 with IC50 0.108 μM and 0.144 μM, respectively. Both derivatives showed better cancerous cell line growth inhibition than erlotinib over HCT-116
设计了 15 种硫代咪唑啉酮衍生物作为 EGFR 和 CDK2 双重抑制剂,并通过 Claisen 和 Knoevenagel 缩合合成。衍生物12显示出最佳的EGFR和CDK2 IC 50 ,分别为0.098μM和0.087μM,其次是13,IC 50分别为0.108μM和0.144μM。与 HCT-116、MCF-7 和 HepG-2 相比,两种衍生物均表现出比厄洛替尼更好的癌细胞系生长抑制作用。此外,结直肠 HCT-116 对 IC 50治疗最敏感12 和 13 的浓度分别为 1.87 μM 和 2.70 μM,而厄洛替尼的浓度为 15.40 μM。此外,12和13的分子对接模拟在分子水平上解释了它们惊人的激酶抑制作用,其中两者都表现出比其与关键氨基酸相互作用巩固的共结晶配体更好的EGFR结合能。类似地,衍生物12显示出与CDK2与其共结晶配体相当的结合能,并证明了与CDK2结合位点和看门残基的特征性相互作用。
