Herein, the discovery of small mol. EGFR degraders based on the proteolysis targeting chimera (PROTAC) strategy was reported. In the present study, 13 EGFR degraders containing pyrido[3,4-d]pyrimidine moiety I [X = CH2C(O)NHCH2CH2C(O), CH2CH2CH2CH2C(O), CH2CH2CH2CH2CH2C(O), etc.], II [C = CH2C(O)NHCH2CH2C(O), CH2CH2CH2CH2CH2CH2CH2C(O)] and III [X = CH2CH2CH2CH2C(O), CH2CH2OCH2CH2OCH2CH2, CH2CH2CH2CH2CH2CH2C(O), etc.] were designed and synthesized. Promising PROTACs I [X = CH2CH2CH2CH2CH2CH2CH2C(O)] and III [X = CH2CH2CH2CH2CH2CH2C(O)] induced degradation of EGFR in HCC827 cells with the DC50 values of 45.2 and 34.8 nM, resp. Cellular protein-controlling machinery ubiquitin proteasome system (UPS) was involved in the degradation process. Furthermore, the degraders I [X = CH2CH2CH2CH2CH2CH2CH2C(O)] and III [X = CH2CH2CH2CH2CH2CH2C(O)] could significantly induce the apoptosis of HCC827 cells and arrest the cells in G1 phase. These findings demonstrated that compounds I [X = CH2CH2CH2CH2CH2CH2CH2C(O)] and III [X = CH2CH2CH2CH2CH2CH2C(O)] could serve as effective EGFRdel19-targeting degraders in HCC827 cells. v. In the part of experimental materials, we found many familiar compounds, such as Ethyl 5-bromovalerate(cas: 14660-52-7Reference of Ethyl 5-bromovalerate)
Ethyl 5-bromovalerate(cas: 14660-52-7) belongs to bromides. One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.Reference of Ethyl 5-bromovalerate
