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.

Features

A potent, selective, and neutral cathepsin K inhibitor.

Targets

Cathepsin K (human) ^[1]	Cathepsin K (rabbit) ^[1]
0.2 nM	1 nM

In vitro
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 vivo	In preclinical rats, Odanacatib (10 mg/kg) exhibits excellent pharmacokinetics with clearance (Cl: 2 mL kg^-1 min^-1), low volume of distribution (V_dss: 1.1 L kg^-1), half-life (T_1/2: 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. ^[4]
