KRAS抑制剂的生长历程

经由多年的起劲，，科学家们在针对几种恶性肿瘤的KRAS突变方面已经取得了多向希望:

After decades of efforts, scientists have made progress into targeting KRAS mutations in several malignancies.

在1967年, Ha-Ras 和 Ki-Ras逆转录病毒转化基因被发明，，它们对应的人类RAS家族HRAS和KRAS于1982年被发明.

In 1967, Ha-Ras and Ki-Ras retroviral transforming genes were discovered.Their human counterparts,Ha-Ras and Ki-Ras ,were discovered in 1982.

KRAS 与肺癌的关系于1984年被首次形貌，，这些年KRAS 突变在肺癌中已经有多项希望。。。。。。突变的KRAS被一连性激活，，并导致一连的下游信号传导和肿瘤爆发。。。。。。

The relationship between KRAS and lung cancer was described in 1984,KRAS mutation in lung cancer has progressed.Mutant KRAS is constitutively activated and leads to persistent downstream signalling and oncogenesis.

在2013年随着对KRAS生物学的相识加深和药物设计手艺的更新，，科学家们在GDP连系的突变型KRAS G12C 卵白中发明了半胱氨酸药物连系袋。。。。。。

In 2013 improved understanding of KRAS biology and newer drug designing technologies led to crucial discovery of a cysteins drug binding pocket in GDP-bound mutant KRAS G12C  protein.

在2021年，，科学家们乐成开发出阻断突变型KRAS G12C 的共价抑制剂。。。。。。2021年5月，，Sotorasib获得FDA批准，，用于治疗KRAS G12C突变的NSCLC，，这是第一个获批的KRAS G12C抑制剂，，现在尚有更多药物正在研发中。。。。。。

In 2021,covalent inhibitors that block mutant KRAS G12C were successfully developed.In May 2021 the US FDA granted accelerated approval to Sotorasib(1st KRAS G12C inhibitor)，，for the treatment of adults with advanced NSCLC with KRAS G12C mutation.Sotorasib was the first KRAS G12C inhibitor to be approved，，with several more in the pipeline。。。。。。
