levels, and conversely, inhibition of EZH2 promoted HIF-1α transcription. HIF-1α and EZH2 interacted to form a negative feedback loop that reinforced each other's activity. In this paper, a series of 2,2- dimethylbenzopyran derivatives containing pyridone structural fragments were designed and synthesized with , a HIF-1α inhibitor previously reported by our group, and , an EZH2 inhibitor approved by
我们之前报道,EZH2抑制剂使HIF-1抑制剂耐药细胞敏感,并抑制HIF-1α促进SUZ12转录,导致EZH2酶活性增强和H3K27me3水平升高,反之,抑制EZH2促进HIF-1α转录。 HIF-1α 和 EZH2 相互作用形成负反馈回路,增强彼此的活性。本文以本课题组先前报道的HIF-1α抑制剂和FDA批准的EZH2抑制剂为先导化合物,设计合成了一系列含有吡啶酮结构片段的2,2-二甲基苯并吡喃衍生物。其中,对HIF-1α和EZH2具有显着的抑制活性。体外实验表明,显着抑制A549细胞的迁移、克隆、侵袭和血管生成。此外,具有良好的药代动力学特征。所有有关化合物的研究结果可为HIF-1α和EZH2双靶向化合物的研发奠定基础。
