Porphyrin derivatives, in particular verteporfin (VP), a photosensitizer initially designed for cancer therapy, have been identified as inhibitors of the YAP-TEAD interaction and transcriptional activity. Herein we report the efficient convergent synthesis of the dipyrrin half of protoporphyrin IX dimethyl ester (PPIX-DME), in which the sensitive vinyl group was created at the final stage by a dehydroiodination
卟啉衍生物,特别是verteporfin(VP),一种最初设计用于癌症治疗的光敏剂,已被确定为YAP-TEAD相互作用和转录活性的抑制剂。本文中,我们报告了原卟啉IX二甲基酯(PPIX-DME)的二吡啶半部分的有效收敛合成,其中敏感的乙烯基是在最后阶段通过脱碘化氢反应生成的。合成了另外两种二吡啶衍生物,包括二吡啶19 [(Z)-2-(((3,5-二甲基-4-乙烯基-2H-吡咯-2-亚烷基)甲基)-3,5-二甲基-4-乙烯基- 1H-吡咯],含有两个乙烯基。我们发现VP和双嘧啶19在MDA-MB-231人乳腺癌细胞中显示出对TEAD转录活性的显着抑制作用,而其他化合物则没有显示出显着变化。此外,我们观察到VP治疗后YAP和TAZ含量均显着降低,而双吡啶19治疗则主要降低了YAP和受体激酶AXL(YAP的下游靶标)的水平。总之,我们的数据表明,由于卟啉和二吡啶相关的衍生物,由于它们的化学结构,
