摘要
Ras-Raf-Mek-Erk信号转导通路在调控细胞生长,分化和增殖起着至关重要的作用。而Ras或者B-Raf的突变都会导致肿瘤的发生。B-Raf被激活后的体细胞突变率在黑色素瘤中高达50%~70%,卵巢癌中达35%,甲状腺癌中达30%,结肠癌中达10%,因此B-RafV600E作为治疗人类癌症的靶标而日益受到研究者的关注。本综述主要从结构优化对活性的影响上阐述了近两年来新型B-Raf激酶抑制剂的最新研究进展。
The Ras-Raf-MEK-ERK signal transduction pathway(ERK pathway) plays a key role in cellular growth,division and proliferation.Mutations of either Ras or B-Raf lead to the development of human cancers.Activating B-Raf mutations have been found in melanomas(50~70%),ovarian cancer(35%),papillary thyroid cancers(30%) and colorectal cancer(10%).Therefore,B-RafV600E is a high-interest therapeutic target for the treatment of human cancers.This review put emphasis on B-Raf kinase inhibitors which was newly approved in rencent literatures,including the effect of B-Raf kinase′s activity brought by structural modification.
