In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
0.8mg/ml Taking the 1 mL working solution as an example, add 50 μL of 16 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. 
Clear solution
4%DMSO Corn oil
5.0mg/ml Taking the 1 mL working solution as an example, add 40 μL of 125 mg/ml clear DMSO stock solution to 960 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
Clear solution
5% DMSO 95% Corn oil
1.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 20 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. 
* <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 Odanacatib is a potent, selective, and neutral inhibitor of cathepsin K (human/rabbit) with IC50 of 0.2 nM/1 nM, and demonstrated high selectivity versus off-target cathepsin B, L, S. Phase 3.
Targets
Cathepsin K (human) [1] Cathepsin K (rabbit) [1]
0.2 nM 1 nM
In vitro In vitro, Odanacatib shows the high inhibitory activity and selectivity on cathepsin K with IC50 values of 0.2 nM and 1 nM for human cathepsin K and rabbit cathepsin K, respectively. Furthermore, Odanacatib also shows similar potencies in whole human cell enzyme occupancy assays with corrected IC50 of 5 nM. [1] A recent study shows that Odanacatib results in reduction of Osteoclast (OC) resorption activity by interrupting intracellular vesicular trafficking. [2]
In vivo In preclinical rats, Odanacatib (10 mg/kg) exhibits excellent pharmacokinetics with clearance (Cl: 2 mL kg-1 min-1), low volume of distribution (Vdss: 1.1 L kg-1), half-life (T1/2: 6 hours) and oral bioavailability (F: 8%), respectively. Besides, Odanacatib also exhibits excellent metabolic stability in rat hepatocytes with a 96% recovery of the parent identity. [1] Odanacatib (ODN) administrated by p.o. prevents bone loss in ovariectomized (OVX) rabbits in a dose-related manner. Moreover, Odanacatib (9 µM/day) leads to a significant increase in proximal femur bone mineral density (BMD) (7.8%), femoral neck BMD (10.8%) and the greater trochanter BMD (6.5%). [3] In the estrogen-deficient, skeletally mature rhesus monkeys, long-term treatment with Odanacatib effectively inhibits bone turnover without reducing osteoclast number and maintains normal biomechanical properties of the spine of OVX nonhuman primates.

Features A potent, selective, and neutral cathepsin K inhibitor.
