Epidermal growth factor receptor (EGFR), a member of the HER family, is closely related to the development of multiple cancers. Herein, we report the discovery of small molecule EGFR degraders based on the proteolysis targeting chimera (PROTAC) strategy. In the present study, 13 EGFR degraders containing pyrido[3,4-d] pyrimidine moiety were designed and synthesized. Promising PROTACs 2 and 10 induced
表皮生长因子受体(EGFR)是HER家族的成员,与多种癌症的发生密切相关。在此,我们报告了基于蛋白水解靶向嵌合体(PROTAC)策略的小分子EGFR降解剂的发现。在本研究中,设计并合成了13个含有吡啶并[3,4-d]嘧啶部分的EGFR降解物。有前景的PROTAC 2和10在HCC827细胞中诱导EGFR降解,DC50值分别为45.2和34.8 nM。细胞蛋白控制机制泛素蛋白酶体系统(UPS)参与了降解过程。此外,降解物2和10可以显着诱导HCC827细胞凋亡,并将其停滞在G1期。这些发现表明,化合物2和10可以作为HCC827细胞中靶向EGFRdel19的有效降解剂。
