生物活性

LC-MB12 is an orally active PROTAC compound targets FGFR2 degradation with a DC50 of 11.8 nM. LC-MB12 contains BGJ398 (a FGFR2 inhibitor), PROTAC linker and CRBN.LC-MB12 inhibits FGFR2 signaling in gastric cancer cells and has anti-tumor activity[1].

IC50 & Target

FGFR2

11.8 nM (DC50)

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.
