IC50 & Target


1.8 nM (IC50)


1900 nM (IC50)

In Vitro

CP21R7 (Compound 9) is a selective inhibitor of GSK-3β, with an IC50 of 1.8 nM; the IC50 of CP21R7 against PKCα is 1900 nM[1]. CP21R7 (CP21, 3 μM) potently activates canonical Wnt signaling with highest activity. CP21 significantly increases total levels of intracellular β-catenin. CP21 combined with BMP4 induces commitment of hPSCs towards mesoderm[2].

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.
