产品描述
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.
体外活性
DBPR112 (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].
体内活性
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/minokg, and a Vss of 8.6 L/kg for rats[1].
