PHPS1 sodium 

PHPS1 sodium is a potent and selective Shp2 inhibitor with K_is of 0.73, 5.8, 10.7, 5.8, and 0.47 μM for Shp2, Shp2-R362K, Shp1, PTP1B, and PTP1B-Q, respectively^[1].

Ki: 0.73 μM (Shp2), 5.8 μM (Shp2-R362K), 10.7 μM (Shp1), 5.8 μM (PTP1B), 0.47 μM (PTP1B-Q)^[1]

PHPS1 (30 μM; 6 days) inhibits proliferation of human tumor cells^[1].
PHPS1 (5-20 μM; 5-360 minutes) inhibits Erk1/2 but not Akt and Stat3 phosphorylation in a dose-dependent manner^[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

PHPS1 (3 mg/kg; i.p. injection; every day during the last week on the high-fat diet) renders Ldlr^-/- mice less susceptible to atherosclerosis development^[2].
