designing anticancer agents. Among the various methods to block the functions of htopoIIα, targeting ATP site for its competitive inhibition has been relatively less investigated. Therefore, to identify some novel htopoIIα inhibitors to target the ATP-binding site, we designed and synthesized a small library of 5-aryl-1,3,4-thiadiazole coupled phthalimide derivatives structurally related to thalidomide.
人拓扑异构酶IIα(htopoIIα)是设计抗癌药物的公认目标。在各种阻断htopoIIα功能的方法中,针对ATP位点的竞争性抑制作用的研究相对较少。因此,为了鉴定一些靶向ATP结合位点的新型htopoIIα抑制剂,我们设计并合成了一个与沙利度胺结构相关的5-芳基-1,3,4-噻二唑偶联的邻苯二甲酰亚胺衍生物的小文库。最初,通过氯化铁催化硫代半脲酮衍生物(THZ 1-8)的氧化环化反应,合成了2-氨基-5-芳基-1,3,4-噻二唑衍生物(TDZ 1-8),后者是通过取代的芳基反应制得的。醛与硫代氨基脲。TDZ 1-8在4Å分子筛和冰醋酸存在下与4-溴邻苯二甲酸酐反应生成5-溴-2-(5-芳基-1,3,4-噻二唑-2-基)异吲哚啉-1,3 -二酮衍生物(PTD 1-8)。通过IR,1 H-NMR和LCMS对所有合成的化合物进行表征。最终化合物PTD 1-8停靠在htopoIIαB链的ATP结
