Migrastatin and isomigrastatin analogues have been synthesised in order to contribute to structure–activity studies on tumour cell migration inhibitors. These include macrocycles varying in ring size, functionality and alkene stereochemistry, as well as glucuronides. The synthesis work included application of the Saegusa–Ito reaction for regio‐ and stereoselective unsaturated macroketone formation
合成了米格他汀和异米格他汀类似物,以促进对肿瘤细胞迁移抑制剂的结构活性研究。这些包括环大小,官能度和烯烃立体化学不同的大环化合物,以及葡糖醛酸苷。合成工作包括应用Saegusa-Ito反应进行区域和立体选择性不饱和大酮形成,非对映选择性布朗烯丙基化以生成9-甲基米格列他汀类似物以及螯合诱导的异化作用以改变葡糖醛酸的构型。化合物在体外针对乳腺癌和胰腺癌细胞系进行了测试,并且在伤口愈合(刮擦)和博登室试验中均观察到了对肿瘤细胞迁移的抑制作用。一种不饱和大酮化合物对一系列次级药物靶标的亲和力低,
