demonstrating the value of this transcription factor for the development of novel anti-cancer therapies. We report herein the design, synthesis and biological evaluation of LM98, a flufenamic acid analogue. LM98 shows strong affinity to TEAD, inhibits its autopalmitoylation and reduces the YAP-TEAD transcriptional activity. Binding of LM98 to TEAD was supported by 19F-NMR studies while co-crystallization
YAP-TEAD 转录复合物负责调节癌细胞生长和增殖的基因的表达。由于 TEAD 的过表达导致 Hippo 通路的失调已在多种癌症中得到报道。TEAD 的抑制抑制了相关基因的表达,证明了这种转录因子对于开发新型抗癌疗法的价值。我们在此报告了氟灭酸类似物 LM98 的设计、合成和生物学评价。LM98 对 TEAD 显示出很强的亲和力,抑制其自棕榈酰化并降低 YAP-TEAD 转录活性。19支持 LM98 与 TEAD 的结合F-NMR 研究同时共结晶实验证实 LM98 锚定在 TEAD 的棕榈酸袋内。LM98 降低CTGF和Cyr61的表达,抑制 MDA-MB-231 乳腺癌细胞迁移并在细胞分裂期间将细胞周期阻滞在 S 期。
