series of dual-protected amino acid derivatives was synthesized and evaluated as potential novel anticancer agents. The 40 derivatives were prepared in up to three reaction steps. The cytotoxic activities were screened in vitro against a panel of tumor and nontumor cells using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Among the synthesized derivatives, three of them showed
癌症是一种慢性退行性疾病,被认为是全球范围内最重要的死亡原因之一。在这种情况下,合成了一系列双重保护的氨基酸衍生物,并将其评估为潜在的新型抗癌药。在多达三个反应步骤中制备了40种衍生物。使用3-(4,5-二甲基噻唑-2-基)-2,5-二苯基四唑溴化物(MTT)测定体外针对一组肿瘤和非肿瘤细胞的细胞毒性活性。在合成的衍生物中,其中三个显示出对癌细胞有希望的活性,其半数抑制浓度(IC50)在1.7-6.1μM之间。具有脂质亲和性N-烷基二胺部分和受保护的氨基酸支架的最有希望的衍生物显示出对肿瘤细胞的选择性指数为3.4。N-烷基二胺部分似乎在增强抗癌活性中起关键作用。另一方面,氨基酸支架的掺入导致对癌细胞系的选择性增加。
