9-diazo-1-methoxy-9H-fluorene, which inhibits the proliferation of HeLa cells, was achieved in reasonable chemical yield. In addition, various diazofluorenes were synthesized using the above protocol and their antitumor effects were evaluated. As a result, several novel diazofluorenes, which have a stronger cytotoxic activity than cisplatin against various human epithelial cancer cells, were found.
我们通过人工智能(AI)提出的设计成功合成了抗肿瘤药1-甲氧基重氮芴。通过应用Pd(OAc)2催化的环芳烃化反应,构建了1-甲氧基重氮芴的关键联苯支架。AI提出的联苯中间体的官能团转化提供了9-重氮-1-甲氧基-9 H-芴,该化合物可抑制HeLa细胞的增殖,并以合理的化学产率实现。此外,使用上述方案合成了各种重氮芴,并评估了它们的抗肿瘤作用。结果,发现了几种新颖的重氮芴,其对各种人上皮癌细胞具有比顺铂强的细胞毒活性。
