  • Lu1205 were treated with protein kinase inhibitors. Cell cycle protein expression was analyzed by western blot.

    Med Oncol, 2017, 35(1):7. CHIR-99021 (CT99021) purchased from Selleck.

    For MTT assays, cells (2,000 ~ 5,000 cells/well) were subcultured into 96-well plates according to their growth properties. Cell proliferation was assayed at 72 hr after treatment of CHIR-99021 by adding 20 μl of 5 mg/ml 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) solution per 100 μl of growth medium. After incubating for 3-4 h at 37°C, the media were removed and 150 µl/well of MTT solvent (either absolute DMSO or isopropanol containing 4 mM HCl and 0.1% Nonidet-40) was added to dissolve the formazan. The absorbance of each well was measured by ELx808 (BioTek, Winooski, VT) or Wallac Victor2 (Perkin-Elmer Life Sciences, Boston, MA) Microplate Reader. Viable cells are presented as percent of control, vehicle-treated cells.

Biological Activity

Description CHIR-99021 (CT99021) is a GSK-3α and GSK-3β inhibitor with IC50 of 10 nM and 6.7 nM, respectively. CHIR99201 does not exhibit cross-reactivity against cyclin-dependent kinases (CDKs) and shows a 350-fold selectivity toward GSK-3β compared to CDKs.
Targets
GSK-3β [1]
(Cell-free assay)
GSK-3α [1]
(Cell-free assay)
6.7 nM 10 nM
In vitro

CHIR-99021 shows greater than 500-fold selectivity for GSK-3 versus its closest homologs CDC2 and ERK2, as well as other protein kinases. Furthermore, CHIR-99021 shows only weak binding to a panel of 22 pharmacologically relevant receptors and little inhibitory activity against a panel of 23 nonkinase enzymes. CHIR-99021 induces the activation of glycogen synthase (GS) in insulin receptor-expressing CHO-IR cells with EC50 of 0.763 μM[1].

In vivo Oral administration of CHIR-99021 at 30 mg/kg enhances glucose metabolism in a rodent model of type 2 diabetes, with a maximal plasma glucose reduction of nearly 150 mg/dl 3-4 hours after administration, while plasma insulin remains at or below control levels. Oral administration of CHIR-99021 at 16 or 48 mg/kg 1 hour before oral glucose challenges in ZDF rats significantly improves glucose tolerance with 14% and 33% reduction in plasma glucose at 16 mg/kg and 48 mg/kg, respectively, and the higher dose of CHIR-99021 also reduces hyperglycemia before the oral glucose challenge[1].

Protocol

Cell Research:

[1]

+ Expand
  • Cell lines: Insulin receptor–expressing CHO-IR cells; Primary rat hepatocytes
  • Concentrations: 0.01-10 μM
  • Incubation Time: 30 min
  • Method:

    CHO-IR cells expressing human insulin receptor are grown to 80% confluence in Hamm’s F12 medium with 10% fetal bovine serum and without hypoxanthine. Trypsinized cells are seeded in 6-well plates at 1 × 106 cells/well in 2 ml of medium without fetal bovine serum. After 24 h, medium is replaced with 1 ml of serum-free medium containing GSK-3 inhibitor or control (final DMSO concentration <0.1%) for 30 min at 37°C. Cells are lysed and centrifuged 15 min at 4°C/14000g. The activity ratio of GS is calculated as the GS activity in the absence of glucose-6-phosphate divided by the activity in the presence of 5 mmol/l glucose-6-phosphate, using the filter paper assay of Thomas et al.
