|Description||Odanacatib (MK 0822) 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.|
|Features||A potent, selective, and neutral cathepsin K inhibitor.|
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.  A recent study shows that Odanacatib results in reduction of Osteoclast (OC) resorption activity by interrupting intracellular vesicular trafficking. 
|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.  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%).  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. |
|In vitro||DMSO||100 mg/mL (190.27 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
4% DMSO+corn oil
For best results, use promptly after mixing.
* 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.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
