PP2

    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 401706

CAS#: 172889-27-9

Description: PP2, also known as AG 1879, is a substance that has frequently been used in cancer research as a "selective" inhibitor for Src-family kinases. It strongly inhibits the kinases Lck (IC50=4 nM), Fyn (5 nM) and Hck (5 nM), shows weaker inhibition of EGFR (480 nM) and practically no inhibition of ZAP-70 (100 µM) and JAK2 (50 µM). Despite its extensive use as a Src-selective inhibitor, recent research has shown that PP2 is non-selective and inhibits many other kinases with similar affinities.
