p70核糖体蛋白S6激酶抑制剂的研究进展

Research progress of p70 ribosomal protein S6 kinase inhibitors

p70核糖体蛋白S6激酶(p70 ribosomal protein S6 kinase,p70S6K)是一种多功能的丝氨酸/苏氨酸蛋白激酶,是AGC家族的重要成员,在m TOR信号通路中起着非常重要的作用。p70S6K与蛋白质的合成、m RNA的加工、葡萄糖的体内平衡以及细胞的生长和凋亡等进程密切相关。研究表明,肿瘤的发生与p70S6K的过度激活有关,因此,p70S6K已成为抗癌药物研发的重要潜在靶点之一。本文对p70S6K的生物学功能、作用机制及相关p70S6K抑制剂结构和研究思路做一综述。

p70 ribosomal protein S6 kinase （p70S6K）, an important member of AGC family, is a kind of multifunctional Ser/Thr kinases, which plays an important role in mTOR signaling cascade. The p70 ribosomal protein S6 kinase is closely associated with diverse cellular processes such as protein synthesis, mRNA processing, glucose homeostasis, cell growth and apoptosis. Recent studies have highlighted the important role of S6K in cancer, which arose interests of scientific researchers for the design and discovery of anti-cancer agents. Herein, the mechanisms of S6K and available inhibitors are reviewed.
