dbpr112

DBPR112 是一种口服有效的基于氟嘧啶的 EGFR 抑制剂，对 EGFRWT 和 EGFRL858R T790M 的 IC50 分别为 15 nM 和 48 nM。DBPR112 可以占据 ATP 结合位点。DBPR112 具有显着的抗肿瘤功效。

DBPR112 is a potent EGFR inhibitor (IC50=487 nM) as a Clinical Candidate for the Treatment of Non-Small Cell Lung Cancer. DBPR112), DBPR112 not only displayed a potent inhibitory activity against EGFRL858R T790M double mutations but also exhibited tenfold potency better than the third-generation inhibitor, osimertinib,against EGFR and HER2 exon 20 insertion mutations. Overall, pharmacokinetic improvement through lead-to-candidate optimization yielded fourfold oral AUC better that afatinib along with F = 41.5%, an encouraging safety profile, and significant antitumor efficacy in in vivo xenograft models.
