Epidermal growth factor receptor (EGFR), a transmembrane glycoprotein that mediates cellular signaling pathways involved in cell proliferation, angiogenesis, apoptosis, and metastatic spread, is an important oncogenic drug target. Targeting the intracellular and extracellular domains of the EGFR has been authorized for a number of small-molecule TKIs and mAbs, respectively. However, their clinical application is limited by EGFR catalytic structural domain alterations, cancer heterogeneity, and persistent drug resistance. To bypass these limitations, protease-targeted chimeras (PROTACs) are emerging as an emerging and promising anti-EGFR therapy. PROTACs compensate for the limitations of traditional occupancy-driven small molecules by exploiting intracellular protein destruction processes. Recently, a mushrooming number of heterobifunctional EGFR PROTACs have been created using wild-type (WT) and mutated EGFR TKIs. PROTACs outperformed EGFR TKIs in terms of cellular inhibition, potency, toxicity profiles, and anti-drug resistance. Herein, we present a comprehensive overview of the development of PROTACs targeting EGFR for cancer therapy, while also highlighting the challenges and opportunities associated with the field.
表皮生长因子受体(EGFR)是一种跨膜糖蛋白,介导细胞增殖、血管生成、凋亡和转移扩散等细胞信号通路,是重要的致癌药物靶点。针对 EGFR 的细胞内和细胞外结构域,已分别获得了多种小分子 TKI 和单克隆抗体的批准。然而,其临床应用受到 EGFR 催化结构域改变、肿瘤异质性和持续耐药性的限制。为了克服这些限制,蛋白酶靶向嵌合体(PROTACs)作为一种新兴且有前途的抗 EGFR 治疗方法正在出现。PROTACs 通过利用细胞内蛋白降解过程来弥补传统占据驱动小分子的局限性。最近,已经使用野生型(WT)和突变型 EGFR TKI 开发了大量的异双功能 EGFR PROTACs。PROTACs 在细胞抑制、效力、毒性特征和抗耐药性方面优于 EGFR TKI。本文全面概述了针对癌症治疗的 EGFR PROTACs 的开发情况,同时强调了该领域相关的挑战和机遇。
