Description

MK-0822 is a novel bone-targeting dual action pro-drug specifically designed for the treatment of osteoporosis and bone metastasis. It functions as an inhibitor of cathepsin K, a crucial enzyme that plays a significant role in bone resorption. By targeting and inhibiting this enzyme, MK-0822 helps to slow down the bone loss associated with osteoporosis and the progression of bone metastasis in cancer patients.

Uses

Used in Pharmaceutical Industry:
MK-0822 is used as a therapeutic agent for the treatment of osteoporosis. It helps to reduce bone loss and increase bone density, thereby improving the overall bone health and reducing the risk of fractures in patients suffering from osteoporosis.
MK-0822 is also used as an anticancer agent for the treatment of bone metastasis. It inhibits the activity of cathepsin K, which is often overexpressed in cancer cells that have metastasized to the bones. By inhibiting this enzyme, MK-0822 can slow down the progression of bone metastasis and alleviate the associated pain and complications.
In addition to its direct therapeutic applications, MK-0822 may also be used as a research tool in the study of bone metabolism and the role of cathepsin K in bone resorption. This can contribute to the development of new therapeutic strategies for bone-related disorders and the understanding of the underlying molecular mechanisms involved in these conditions.

Bioactivity

Odanacatib (MK-0822) is an effective and selective neutral inhibitor for cathepsin K(human /rabbit) and IC50 is 0.2 nM/1 nM.? It has high selectivity for off-target cathepsin B, L, S. Phase 3。

In vitro

In vitro, Odanacatib acts on cathepsin K with high inhibitory activity and selectivity with IC50 of 0.2 nM and 1 nM when it acts on cathepsin K of human and rabbits. Odanacatib is also effective in all human enzyme experiments with IC50 of 5 nM.

In vivo

With a dosage of 10 mg/kg acting on preclinical rats, Odanacatib has good pharmacokinetic characteristics such as scavenging activity(Cl: 2 mL kg-1 min-1), low distribution (Vdss: 1.1 L kg-1), half-life(T1/2: 6 h) and Orally bioavailable (F: 8%).In addition, Odanacatib has a good metabolic stability if it acts on the Parental rats with 96% recovery of live. With the dosage of 9?μM, Odanacatib can significantly Increase the Proximal femur bone mineral density (BMD) (7.8%), femoral neck BMD (10.8%) and thighs greater trochanter BMD (6.5%). Long-term treatment with Odanacatib on skeletal matured macaque which is lack of estrogen can efficiently inhibit the bone metabolism, and will not reduce the number of osteoclast. It can also maintain the biomechanics properties of nonhuman primates with Ovary resection (OVX).

Features

Odanacatibis an effective and selective neutral inhibitor for cathepsin K

Biological Activity

odanacatib (mk-0822) is a potent, orally active and selective inhibitor of cathepsin k with ic50 value of 0.20 nm [1],cathepsin k is expressed predominantly in osteoclasts and degrades the collagen matrix componentsofbone. it plays a central role in mediating bone resorption. and the inhibitor of cathepsin k, odanacatib, is in development for the treatment of osteoporosis. based on preclinical evidence and available clinical data from dose-ranging phase iib trials, odanacatib appears to reduce bone resorptionwhile somewhat preserving bone formation in postmenopausalwomen. currently, odanacatib is undergoing evaluation for fracture risk reduction in a phase iii trial with >16000 patients with postmenopausal osteoporosis [2].chantal mahon, anish mehta, kate mostoller, stefan zajic, denise morris, jessie lee, and s. aubrey stoch. odanacatib, a selective cathepsin k inhibitor, demonstrates comparable pharmacodynamics and pharmacokinetics in older men and postmenopausal women. endocrine research. 2014, 99(2):552–560.

Enzyme inhibitor

This investigational osteoporosis/bone-metastasis drug (FW = 525.56 g/mol; CAS 603139-19-1), also known by the code name MK-0822 and its systematic name N-(1-cyanocyclopropyl)-4-fluoro-N2-{(1S)-2,2,2-trifluoro- 1-[4'-(methylsulfonyl)biphenyl-4-yl]ethyl}-L-leucinamide, targets the cathepsin K, a unique collagenolytic lysosomal cysteine protease that is secreted, thereby facilitating bone resorption by cleaving type-1 collagen under acidic pH. Cathepsin K exhibits a unique cleavage pattern of type I collagen molecules that is fundamentally different from that of other endogenous collagenases. Women receiving ODN (10-50 mg) for 5 years had gains in spine and hip bone mineral density (BMD), showing larger reductions in bone resorption than bone formation markers. Significantly, discontinuation of ODN resulted in reversal of treatment effects. An odanacatib synthesis, which describes a novel stereospecific SN2 triflate displacement of a chiral a-trifluoromethylbenzyl triflate with (S)-g-fluoroleucine ethyl ester, achieves a 61% overall yield in 6 steps.

Check Digit Verification of cas no

The CAS Registry Mumber 603139-19-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,0,3,1,3 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 603139-19:
(8*6)+(7*0)+(6*3)+(5*1)+(4*3)+(3*9)+(2*1)+(1*9)=121
121 % 10 = 1
So 603139-19-1 is a valid CAS Registry Number.
