生物活性

ISM7594 is an orally active FGFR2/3 inhibitor. ISM7594 shows broad-spectrum antiproliferative potency in FGFR2- or FGFR3-altered cancer cell panels, including FGFR2/3 amplification, fusion, and mutation (BaF3-TEL-FGFR2-V564F (IC50 = 0.067 nM), BaF3-TEL-FGFR2-V564I (IC50 = 2 nM)) types. ISM7594 inhibits tumor growth in a dose-dependent manner. ISM7594 can be used for the study of advanced solid tumors with FGFR2/3 aberrations[1].

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.
