of the ras oncogene product by Farnesyl Transferase (FTase) is known to be a critical step in cell transformation leading to uncontrolled proliferation. The peptide CysValTicMet is a potent FTase inhibitor, but its degradation by amino-peptidases and its only weak internalization into cells make it a bad candidate for a future cancer drug. We have prepared improved CysValTicMet analogues using several
已知法呢基转移酶(FTase)对ras癌基因产物进行法呢基化是导致细胞转化不受控制的关键转化步骤。CysValTicMet肽是一种有效的FTase抑制剂,但其被氨基肽酶降解以及仅微弱地内化进入细胞,使其成为未来癌症药物的不佳选择。我们使用几种方法制备了改良的CysValTicMet类似物:(i)氨基末端修饰或引入伪肽或非天然氨基酸以增加蛋白水解稳定性,(ii)引入疏水性脂族链以增加细胞内在化和代谢稳定性,以及(iii)转变为前药。另外,
