dbpr 112

DBPR112 is an orally active furanopyrimidine-based EGFR inhibitor with IC50s of 15 nM for EGFRWT and 48 nM for EGFRL858R/T790M, capable of occupying the ATP-binding site and demonstrating significant antitumor efficacy.

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.
