Rationale: The type I insulin-like growth factor receptor (IGF-1R) signaling pathway plays key roles in the development and progression of numerous types of human cancers, and Src and AXL have been found to confer resistance to anti-IGF-1R therapies. Hence, co-targeting Src and AXL may be an effective strategy to overcome resistance to anti-IGF-1R therapies. However, pharmacologic targeting of these three kinases may result in enhanced toxicity. Therefore, the development of novel multitarget anticancer drugs that block IGF-1R, Src, and AXL is urgently needed.
理由:I型
胰岛素样生长因子受体(IGF-1R)信号通路在多种类型人类癌症的发生和发展过程中发挥着关键作用,而Src和AXL已被发现会产生抗IGF-1R疗法的耐药性。因此,联合靶向Src和AXL可能是克服抗IGF-1R疗法耐药性的有效策略。然而,药物靶向这三种激酶可能会导致毒性增强。因此,亟需开发能阻断 IGF-1R、Src 和 AXL 的新型多靶点抗癌药物。
