-one derivatives showing promising antiproliferative activities in variety of cancer cell lines. In this work, racemic syntheses of nine novel 4′-alkyl substituted klavuzon derivatives were completed in eight steps and anticancer properties of these compounds were evaluated. It is found that size of the substituent has dramatic effect over the potency and selectivity of the cytotoxic activity in cancerous
克拉维松是6-(萘-1-基)取代的5,6-二氢-2 H-吡喃-2-酮衍生物在多种癌细胞系中显示出有希望的抗增殖活性。在这项工作中,分八步完成了九种新颖的4'-烷基取代的克拉维松衍生物的外消旋合成,并评估了这些化合物的抗癌性能。发现在癌症和健康的胰腺细胞系中,取代基的大小对细胞毒性活性的效力和选择性具有显着影响。取代基的大小也可以影响克拉维松衍生物的CRM1抑制特性。仅当萘-1-基的4'-位存在一个小的取代基时,才能观察到强的细胞毒活性和CRM1抑制作用。但是,这些取代基使该分子在健康的胰腺细胞而不是癌性胰腺细胞中更具细胞毒性。在测试的化合物1,2,3中,
