  • Potent inhibitor of DYRKs (DYRK1A (IC50=40nM); DYRK2 (IC50=35nM)) and CLKs (CLK1, CLK3). Interacts also with GSK-3α/β, CK2 and PIM1.
  • Interacts with the complex PIKfyve/Vac14/Fig4.
  • Modulates alternative splicing of pre-mRNA in various cellular systems.
  • Neuroprotective against APP-induced cell death.
  • Tools to study and modulate pre-RNA splicing. Potential compound for Alzheimer's disease and diseases involving abnormal pre-mRNA splicing.
  • Potential compound to study Down syndrome (inhibition of DYRK1A).
  • Neuroprotective against glutamate-induced cell death.
  • Autophagy activator.
