  4. MS9427

MS9427 is a potent PROTAC EGFR degrader with Kds of 7.1 nM and 4.3 nM for EGFR WT and EGFR L858R, respectively. MS9427 selectively degrades the mutant but not the WT EGFR through both the ubiquitin/proteasome system (UPS) and autophagy/lysosome pathways. MS9427 potently inhibits the proliferation of NSCLC cells. MS9427 can be used for researching anticancer.

In Vitro

MS9427 has antiproliferative activity against HCC-827 cells, with a GI50 of 0.87 ± 0.27 μM[1].
MS9427 (0-10 μM, 16 h) potently induces EGFRDel19 degradation (DC50=82 ± 73 nM) and inhibits EGFR phosphorylation (p-EGFR) in a concentration-dependent manner in HCC-827 cells[1].

MedChemExpress (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.
