PHPS1 sodium 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.
体外研究
PHPS1 (30 μM; 6 days) inhibits proliferation of human tumor cells.
PHPS1 (5-20 μM; 5-360 minutes) inhibits Erk1/2 but not Akt and Stat3 phosphorylation in a dose-dependent manner.
Cell Viability Assay
Cell Line:
Human cancer cell lines MDA-MB-435, HCT-116 (colon carcinoma), HCT-15 (colon carcinoma), PC-3 (prostate carcinoma), HT-29 (colon carcinoma), NCI-H661 (lung carcinoma), and Caki-1 (kidney carcinoma)
Concentration:
30 μM
Incubation Time:
6 days
Result:
Resulted in a reduction in cell number of between 0% (Caki-1) to 74% (HT-29).
Western Blot Analysis
Cell Line:
Madin-Darby canine kidney (MDCK) cells
Concentration:
5, 10, 20 μM
Incubation Time:
5, 15, 60, 120, 360 minutes
Result:
Inhibited HGF/SF (1 unit/mL)-induced phosphorylation and thus activation of Erk1/2 over a time period of 15 min to 6 h. In contrast, transient phosphorylation of Erk1/2 after 5 min was not affected.
Exhibited no effect on HGF/SF-induced activation of PI3K/Akt or Stat3.
体内研究
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.
Animal Model:
Ldlr (005061) mice
Dosage:
3 mg/kg
Administration:
Intraperitoneal (i.p.) injection; every day during the last week on the high-fat diet.
Result:
Revealed a significant decrease in atherosclerotic plaque size in the aorta compared with the other two groups.
