acid (FA) was reported to bind in a liphophilic TEAD palmitic acid (PA) pocket, leading to reduction of the expression of Axl and NF2. Here, we show that the replacement of the trifluoromethyl moiety in FA by aromatic groups, directly connected to the scaffold or separated by a linker, leads to compounds with better affinity to TEAD. Co-crystallization studies show that these compounds bind similarly
Hippo 通路通过控制细胞增殖和凋亡来调节器官大小和组织稳态。YAP-TEAD 转录因子是 Hippo 通路的下游效应子,调节CTGF、Cyr61、Axl和NF2等基因的表达。已在多种癌症中发现异常的 Hippo 活性。据报道,氟芬那酸 (FA) 结合在亲脂性 TEAD 棕榈酸 (PA) 口袋中,导致Axl和NF2表达减少。在这里,我们表明,用芳香族基团取代 FA 中的三氟甲基部分,直接连接到支架或通过接头分开,可以产生与 TEAD 具有更好亲和力的化合物。共结晶研究表明,这些化合物与 FA 的结合方式类似,但在 PA 口袋的深处。我们的研究确定 LM-41 和 AF-2112 是两种 TEAD 结合剂,可强烈降低CTGF、Cyr61、Axl和NF2的表达。LM-41 对人类 MDA-MB-231 乳腺癌细胞的迁移具有最强的抑制作用。
