emerged as a potential therapeutic target, as its expression in cancer cells is closely associated with tumor progression and metastasis. Following the initial discovery of a series of thiazole derivatives that demonstrated potent antimigration and antiinvasion activities via possible inhibition of fascin function, we report here the design and synthesis of 63 new thiazole derivatives by further structural
Fascin 最近已成为潜在的治疗靶点,因为它在癌细胞中的表达与肿瘤进展和转移密切相关。在最初发现一系列通过可能抑制肌成束蛋白功能而表现出有效抗迁移和抗侵袭活性的噻唑衍生物之后,我们在此报告了 63 种新型噻唑衍生物的设计和合成,通过进一步的结构修饰来寻找更有效的肌成束蛋白抑制剂。在噻唑氮上具有更长烷基链取代的5系列类似物比具有其他结构基序的类似物表现出更大的抗迁移活性。最强大的模拟,5p,在 24 nM 时抑制了 50% 的细胞迁移。此外,噻唑类似物显示出很强的抗血管生成活性,在鸡胚胎膜试验中阻断了新血管的形成。最后,进行了一项功能研究,以通过与 F-肌动蛋白捆绑蛋白肌成束蛋白的相互作用来研究作用机制。
