| Bioactivity | SB 216763 is potent, selective and ATP-competitive GSK-3 inhibitor with IC50s of 34.3 nM for both GSK-3α and GSK-3β. | ||||||||||||
| Invitro | SB-216763 (10-20 µM) induces β-catenin mediated-transcription in a dose-dependent manner in HEK293 cells. SB-216763 (10, 15 and 20 µM) can maintain mESCs with a pluripotent-like morphology in long-term culture. SB-216763 (10 µM) can maintain J1 mESCs in a pluripotent state for more than a month[2]. SB-216763 inhibits GSK-3 with IC50 of 34 nM[3]. SB-216763 is equally effective at inhibiting human GSK-3α and GSK-3β[5]. | ||||||||||||
| In Vivo | SB216763 (20 mg/kg, i.v.) significantly improves the survival of BLM-treated mice. Mice randomized to receive BLM plus SB216763 shows a noteworthy reduction, compared with BLM-treated mice. SB216763 (20 mg/kg, i.v.) reduces the magnitude of BLM-induced alveolitis[1]. SB 216763 (0.2 mg/kg, i.v.) with either 17β-E100 or Geni100 reverses the ceiling effect because these agents significantly reduce infarct size when the rabbits' hearts are submitted to 30-min CAO[4]. | ||||||||||||
