    Product Description

    PHPS1 is a cell-permeable, phosphotyrosine mimetic that inhibits the Src homology region 2 domain-containing phosphatase (SHP)-2 (IC50 = 2.1 µM; Ki = 0.73 µM).1 It is selective for SHP-2, inhibiting ECPTP, PTP1B, SHP-1, and mycobacterium MptpA at relatively higher concentrations (IC50s = 5.4, 19, 30, and 39 µM, respectively).1 PHPS1 has been shown to inhibit SHP-2-dependent cellular signaling and tumor cell colony formation.1
