Application

XAV939 has been used in the inhibition
  • of tankyrase in neuroblastoma cell lines
  • of diphtheria toxin-like ADP-ribosyltransferases (ARTD) in medulloblastoma cells
  • of wnt signalling in human induced pluripotent stem cells (hiPSCs)

Biochem/physiol Actions

XAV939 is a cell-permeable dihydrothiopyranopyrimidinol, which elicits anti-tumor functionality against colon, lung, breast and liver cancer. It binds to catalytic poly-ADP-ribose polymerase (PARP) domain of the tankyrase enzyme resulting in β-catenin destruction. It also inhibits tankyrase in neuroblastoma promoting apoptosis in tumor cells.
XAV939 is a Tankyrase inhibitor (thereby inhibiting Wnt / β-catenin signaling)
