Clear solution	5% DMSO 1 95% Corn oil	0.32mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 6.4 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O	3.25mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 65 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description

WAY-262611 (BML-WN110, Compound 5) is a beta-catenin (β-Catenin) agonist that increases bone formation rate with EC50 of 0.63 μM in TCF-Luciferase assay. WAY-262611 is also an inhibitor of dickkopf 1 (DKK1).

Targets

DKK1 ^[2]	β-Catenin ^[1] (TCF-Luciferase assay)
	0.63 μM(EC50)

In vitro

WAY-262611, the DKK1 inhibitor, blocks DKK1 and restores the GDF5 reduced MMP13 gene expression.^[2]

In vivo

WAY-262611 has excellent pharmacokinetic properties and shows a dose dependent increase in the trabecular bone formation rate in ovariectomized rats following oral administration.^[1]

Protocol (from reference)

Cell Assay:^{^[2]}	Cell lines Surplus human chondrocytes Concentrations 0.01 μM, 0.1 μM, 1 μM Incubation Time 21 days Method The cell suspension is divided into aliquots of 200 μl to each well of an uncoated flat bottom 96-well plate. The plate is centrifuged at 1,500 rpm for 5 min and incubated for 48 h at 37°C in 5% CO₂ and 90% relative humidity to allow for pellet formation. After 48 h the culture medium is changed to BDM supplemented with appropriate growth factors (GFs); 2, 10, 100 or 200 ng/ml recombinant GDF5, 50 ng/ml recombinant Wnt3a, 0.5 μM GSK3b inhibitor CHIR-99021, 0.01, 0.1 or 1 μM DKK1 inhibitor WAY-262611. Medium is changed three times per week for 21 days, whereafter the pellets are snap-frozen in liquid nitrogen and stored at -80°C.
