Description

Cathepsin K inhibitor 3 (compound 23) is a highly selective cathepsin K inhibitor with an IC50 value of 0.5 nM. Cathepsin K inhibitor 3 has a favorable pharmacokinetic profile and may be used in osteoarthritis (OA) disease studies[1].

IC50 & Target[1]

cathepsin K

0.5 nM (IC50)

In Vivo

Cathepsin K inhibitor 3 (compound 23) (p.o., 0.03-15 mg/kg, daily, 4 days) results in a significant and dose-dependent reduction in uCTX-I, with an 81% reduction in uCTX-1 levels at 0.3 mg/kg and a slightly more complete reduction at 15 mg/kg in dog[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
