Bioactivity

GW2580 is an orally bioavailable and selective inhibitor of c-Fms kinase which completely inhibits human cFMS kinase in vitro at 0.06 μM. GW2580 acts as a competitive inhibitor of ATP binding to the cFMS kinase and inhibits colony-stimulating-factor-1 signaling[1].

Target

IC50: 60 nM (c-FMS)

Invitro

GW2580 completely inhibits the growth of CSF-1-dependent mouse myeloid M-NFS-60 cells at 0.7 μM. GW2580 at 0.8-1 μM completely blocks the ability of CSF-1 to induce the growth of mouse M-NFS60 myeloid cells and human monocytes[1]. GW2580 causes a 30-40% inhibition of PTH-induced calcium release at 0.1-0.3 μM, with higher concentrations of 1, 3, and 10 μM completely inhibiting the PTH response[1]. GW2580 inhibits CSF1R phosphorylation in RAW264.7 murine macrophages stimulated with 10 ng/mL with IC50 of approximately 10 nM[2]. GW2580 also inhibits TRKA activity with IC50 of 0.88 μM[3].

In Vivo

GW2580 (Oral administration; 20 and 80 mg/kg) produces a dose-related decrease in the number of tumor cells, with the 80 mg/kg dose completely blocking tumor growth[1]. GW2580 (Oral administration; 20 and 80 mg/kg) has gave maximal plasma concentrations of 1.4 and 5.6 μM, respectively[1]. GW2580 (50 mg/kg; twice a day from days 0 to 21, 7 to 21, or 14 to 21) inhibits joint connective tissue and bone destruction in a 21-day adjuvant arthritis model[3]. Animal Model:
