项目摘要
(1) Blockade of the ERK-MAP kinase pathway bytreatment with PD98059, a specific inhibitor of MEK, completely suppressed the growth of tumor cells in which the pathway is constitutively activated. Selective up-regulation of P27^<Klp1> was observed alter PD98059 treatment of these tumorcells. The up-regulation of p27^<Klp1> correlated with increased association of p27^<Klp1> with cyclin E-CDK2 complexes, a concomitant inhibition of cyclin E-CDK2 kinase activity, and consequent decrease in the phosphorylation state of RB, which would culminate in the marked G1 cell cycle arrest observed in these tumor cells. Furthermore, PD98059-treatment induced a modest apoptotic response in several tumor cells in which the ERK-MAP pathway is constitutively activated. In cotrast, although PD98059 inhibited the proliferation of human diploid fibroblasts to a considerable degree, it never caused any apoptotic response in these cells. Moreover, growth-inhibited diploid fibroblasts reinitiated proliferation … More soon after removal of the inhibitor. These results strongly suggest that the the ERK-MAP kinase pathway is a potential therapeutic target in a group of tumor cells in which the pathway is constitutively activated.(2) Several polyphenols isolated from green tea leaves potently inhibited the ERK-MAP kinase pathway. These were (-)-epigallocatechin-3-gallate (EGCG) and its derivates. The molecular target of these polyphenols was suggested not to be MEK. Furthermore, several thiofravone derivativates of PD98059 such as 2-(2-amino-3-methoxyphenyl) thiochromone and 2-(2-amino-3-chrophenyl) thiochromone inhibited MEk activity more strongly than PD98059 in in vitro and in vivo experiments.(3) An anthrapyrazolone derivative (SP600125), which was originally developed as a potent inhibitor against c-Jun N-terminal kinase, was synthesized. This compound inhibited the growth of many tumor cells by arresting them at G2/M phase but not at G1 phase of the cell cycle. Thus, this compound issuggested to provide us with anew type of anti-tumor agent. Less
(1)用MEK的特异性抑制剂PD 98059阻断ERK-MAP激酶通路,可完全抑制该通路被组成性激活的肿瘤细胞的生长。在<Klp1>PD 98059处理这些肿瘤细胞后,观察到P27 α的选择性上调。p27 β的上调<Klp1>与p27 β与细胞<Klp1>周期蛋白E-CDK 2复合物的结合增加、细胞周期蛋白E-CDK 2激酶活性的伴随抑制以及RB磷酸化状态的随之降低相关,这将导致在这些肿瘤细胞中观察到的显著的G1细胞周期停滞。此外,PD 98059处理诱导了几种肿瘤细胞中的适度凋亡反应,其中ERK-MAP途径被组成性激活。相反,尽管PD 98059在相当程度上抑制人二倍体成纤维细胞的增殖,但它从未在这些细胞中引起任何凋亡反应。此外,生长抑制的二倍体成纤维细胞重新启动增殖 ...更多信息 在去除抑制剂后不久。这些结果有力地表明,ERK-MAP激酶途径是一组肿瘤细胞中的潜在治疗靶点,其中该途径被组成性激活。(2)从绿色茶叶中分离的几种多酚类物质有效地抑制了ERK-MAP激酶途径。这些是(-)-表没食子儿茶素-3-没食子酸酯(EGCG)及其衍生物。这些多酚的分子靶标被认为不是MEK。此外,在体外和体内实验中,PD 98059的几种噻呋酮衍生物如2-(2-氨基-3-甲氧基苯基)硫色酮和2-(2-氨基-3-色苯基)硫色酮比PD 98059更强烈地抑制MEk活性。(3)合成了一种蒽吡唑啉酮衍生物(SP 600125),其最初被开发为针对c-Jun N-末端激酶的有效抑制剂。该化合物通过将许多肿瘤细胞阻滞在细胞周期的G2/M期而不是G1期来抑制肿瘤细胞的生长。因此,该化合物有望为我们提供一种新型的抗肿瘤药物。少
