Bioactivity

• In Vitro:
  SKL2001 upregulated β-catenin responsive transcription by increasing the intracellular β-catenin protein level and inhibited the phosphorylation of β-catenin at residues Ser33/37/Thr41 and Ser45, which would mark it for proteasomal degradation, without affecting CK1 and GSK-3β enzyme activities. SKL2001 disrupted the Axin/β-catenin interaction, which is a critical step for CK1- and GSK-3β-mediated phosphorylation of β-catenin at Ser33/37/Thr41 and Ser45. The treatment of mesenchymal stem cells with SKL2001 promoted osteoblastogenesis and suppressed adipocyte differentiation, both of which were accompanied by the activation of Wnt/β-catenin pathway. SKL2001 did not affect either NF-κB or p53 reporter activity and inhibits β-catenin phosphorylation without affecting GSK-3β activity.
• Cell Research:
  The HEK293 reporter and control cell lines were established. The HEK293 reporter cells were inoculated into 384-well plates at 10 000 cells per well and grown for 24 h. Next, each compound in the chemical library (～270 000) was added to at a final concentration of 20 μM. After 15 h, the plates were assayed for firefly luciferase activity.(Only for Reference)
