ES-072 是一种口服有效的选择性 EGFR 突变体 (EGFR-T790M) 抑制剂。ES-072 通过抑制 EGFR-T790M 活性来激活 GSK3α,从而促进 PD-L1 在 Ser279 和 Ser283 位点的磷酸化。磷酸化的 PD-L1 促使 E3 泛素连接酶 ARIH1 的招募,进一步标记 PD-L1 进行泛素化和蛋白酶体介导的降解。这一机制不仅减少了癌症细胞的生长,还通过降低 PD-L1 的水平,增强了抗肿瘤免疫反应。ES-072 可用于抑制非小细胞肺癌细胞 (NSCLC) 增殖。

生物活性

ES-072 is an orally effective selective EGFR mutant (EGFR-T790M) inhibitor. ES-072 activates GSK3α by inhibiting EGFR-T790M activity, which promotes phosphorylation of PD-L1 at Ser279 and Ser283. The phosphorylated PD-L1 recruits the E3 ubiquitin ligase ARIH1, leading to ubiquitination and proteasomal degradation of PD-L1. This mechanism not only reduces cancer cell growth but also enhances anti-tumor immune response by lowering PD-L1 levels. ES-072 can be used to inhibit proliferation in non-small cell lung cancer (NSCLC) cells[1][2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
