Biological Activity:
WAY-316606 is a novel potent and selective inhibitor of secreted frizzled-related protein-1 (sFRP-1) with an IC50~ 0.65 μM. It prevents sFRP-1 from interacting with Wnt and thus increases Wnt signaling. WAY-316606 can increase total bone area in a murine calvarial organ culture assay.
How to Use:
- In vitro: WAY-316606 was used at 1-10 µM final concentration in various in vitro assays.
- In vivo:n/a
