GW2580 is a small-molecule inhibitor of cFMS kinase; at 60nM it inhibited human cFMS kinase completely in vitro and was inactive against 26 other kinases. GW2580 inhibited lipopolysaccharide (LPS)-induced TNF production in mice, but not LPS-induced TNF production in freshly isolated human monocytes and mouse macrophages in vitro. Also, GW2580 at 1uM totally inhibited CSF-1-induced growth of mouse M-NFS-60 myeloid cells and human monocytes, and prevented bone degradation in cultures of rat calvaria and rat fetal long bone in vitro.
Solubility:Soluble in DMSO at 40mg/ml; very poorly soluble in ethanol; very poorly soluble in water; maximum solubility in plain water is estimated to be about 20-100uM; buffers, serum, or other additives may increase or decrease the aqueous solubility.
Storage and Stability:Long-term storage is recommended at -20°C. For maximum recovery of product, centrifuge the original vial prior to removing the cap.
