體外研究
(In Vitro)

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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

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.
