synthesis and bioassay studies, we identified 9-aminoacridine derivatives with an acridine scaffold as potentially interesting novel dual VEGFR-2 and Src inhibitors. The acridine scaffold has been historically used for deriving topoisomerase inhibitors, but has not been found in existing VEGFR-2 inhibitors and Src inhibitors. A series of 21 acridine derivatives were synthesized and evaluated for their antiproliferative
VEGFR-2和Src激酶均在癌症中发挥重要作用。在某些癌症中,Src与VEGFR-2协同作用以促进其激活。针对VEGFR-2和Src的多靶点药物的开发具有针对这些癌症的治疗优势。通过使用分子对接和SVM虚拟筛选方法,并基于随后的合成和生物测定研究,我们确定了带有an啶支架的9-氨基ac啶衍生物可能是有趣的新型VEGFR-2和Src双重抑制剂。cr啶支架在历史上一直用于衍生拓扑异构酶抑制剂,但在现有的VEGFR-2抑制剂和Src抑制剂中尚未发现。合成了一系列21种a啶衍生物,并评估了其对K562,HepG-2和MCF-7细胞的抗增殖活性。这些化合物中的一些在体外显示出比伊马替尼更好的抗K562细胞活性。分析了这些化合物的构效关系(SAR)。化合物之一(7r)显示出对K562和HepG-2癌细胞系的低μM活性,并且在50μM下分别以44%和8%的抑制率抑制了VEGFR-2和Src,而没有抑制
