尽管经过了30多年的密集努力,但还没有有效的RAS癌蛋白药物抑制剂进入临床,这促使人们普遍认为,RAS蛋白是“无法下药的”。然而,人们重新燃起了希望,认为情况并非如此。在这篇综述中,我们总结了五个主要方向的进展和前景。首先,我们重点介绍了RAS的直接抑制剂的前景。其次,我们重新讨论了阻断RAS膜结合是否是可行方法的问题。第三,我们评估了靶向RAS下游效应信号的现状,可以说这是目前最有利的方向。第四,我们讨论了寻找突变的RAS的合成致死相互作用因子是否仍然有希望。最后,最近描述了RAS介导的细胞代谢变化。可以利用这些变化来寻找新的治疗方向吗?最后,我们对尚未完全了解的额外复杂性可能如何影响这些方法进行了展望。
Despite more than three decades of intensive effort, no effective pharmacologic inhibitors of the Ras oncoproteins have reached the clinic, prompting the widely held perception that Ras proteins are “undruggable”. However, there is renewed hope that this is not the case. In this review, we summarize the progress and promise of five key directions. First, we focus on the prospects of direct inhibitors of Ras. Second, we revisit the issue of whether blocking Ras membrane association is a viable approach. Third, we assess the status of targeting Ras downstream effector signalling, arguably the most favourable current direction. Fourth, we address whether the search for synthetic lethal interactors of mutant RAS still holds promise. Finally, Ras-mediated changes in cell metabolism have recently been described. Can these changes be exploited for new therapeutic directions? We conclude with perspectives on how additional complexities, not yet fully understood, may impact each of these approaches.
