DBPR112 is an orally active furanopyrimidine-based EGFR inhibitor with IC50s of 15 nM and 48 nM for EGFRWT and EGFRL858R/T790M, respectively. DBPR112 can occupy the ATP-binding site. DBPR112 has significant antitumor efficacy[1].
DBPR112 (compound 78; 0.32-1000 nM; 16 hours) induces reduction of phosphorylated EGFR in a dose-dependent manner[1]. DBPR112 shows the inhibitory activity against HCC827 (CC50=25 nM), H1975 (CC50=620 nM) and A431 Cell (CC50=1.02 μM) cell lines[1]. DBPR112 occupies the ATP-binding site and interacts with surrounding residues by covalent bonding, hydrogen bonds, and hydrophobic interactions, which give it a potent inhibitory activity against WT EGFR[1].
DBPR112 (orally; 20-50 mg/kg; 5 days/week for 2 consecutive weeks) significantly reduces tumor growth in HCC827 tumor model. DBPR112 (orally; 50 mg/kg; once a day for 15 days) has a significant antitumor effect (mean tumor growth inhibition of 34%) in H1975 tumor model[1]. DBPR112 (IV; 5 mg/kg) has a T1/2 of 2.3 hours, a CL of 55.6 mL/min•kg, and a Vss of 8.6 L/kg for rats[1].

Discovery of a Furanopyrimidine-Based Epidermal Growth Factor Receptor Inhibitor (DBPR112) as a Clinical Candidate for the Treatment of Non-Small Cell Lung Cancer
J Med Chem 2019 Nov 27;62(22):10108-10123.PMID:31560541DOI:10.1021/acs.jmedchem.9b00722
Epidermal growth factor receptor (EGFR)-targeted therapy in non-small cell lung cancer represents a breakthrough in the field of precision medicine. Previously, we have identified a lead compound, furanopyrimidine 2, which contains a (S)-2-phenylglycinol structure as a key fragment to inhibit EGFR. However, compound 2 showed high clearance and poor oral bioavailability in its pharmacokinetics studies. In this work, we optimized compound 2 by scaffold hopping and exploiting the potent inhibitory activity of various warhead groups to obtain a clinical candidate, 78 (DBPR112), which 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. DBPR112 is currently undergoing phase 1 clinical trial in Taiwan.
