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