Biological Activity of GW2580

DescriptionPotent and selective cFMS kinase inhibitor (IC50 = 0.06 μM). Exhibits selectivity for cFMS kinase over 186 other kinases. Inhibits CSF-1-induced growth of rat monocytes in vitro. Also inhibits bone resorption in osteoclast cultures, as well as connective tissue and bone destruction in a rat adjuvant arthritis model. Suppresses M-NFS-60 tumor cell growth in mice. Orally bioavailable.

Protocol

Kinase Assay [1]
The enzyme is activated by autophosphorylation by incubating 10 μM enzyme, 100 μM ATP, and 5 mM MgCl2 in 50 mM Tris HCL for 90 min at room temperature. Enzyme reactions are performed in a volume of 45 μL, by using round-bottom polystyrene 96-well plates on a Biomek 2000. Compound in 1 μL DMSO or DMSO alone are added to each well containing 30 μL of a 1.5× substrate reaction mix containing 50 mM Mops (3-[N-Morpholino]propanesulfonic acid), pH 7.5, 15 mM MgCl2, 6 μM peptide substrate, biotin-EAIYAPFAKKK-NH2 7.5 mM DTT, 75 mM NaCl, 10 μM ATP, and 0.5 μCi (1 Ci=37 GBq) [33P-γ] ATP per assay. The reaction is initiated by the addition of 15 μL of diluted enzyme solution, resulting in a final enzyme concentration 20 nM. EDTA is added to control wells for determination of background. The reaction is allowed to proceed for 40 min and stopped by the addition of an equal volume of 0.5% phosphoric acid, and 75 μL is transferred to a 96-well phosphocellulose filter plate that has been prewet with 100 μL of 0.5% phosphoric acid. The plate is filtered on a Millipore filter-plate vacuum manifold and washed three times with the phosphoric acid solution, followed by the addition of 40 μL of scintillation solution. The plates are sealed and counted in a Packard Topcount NXT scintillation counter.

Cell Assay [1]
One day before the start of the cell growth assay the cells are spun down and placed in a depleted media at 2×106cells per mL for 24 h. Depleted medium for M-NSF60 cells lacks MCSF. The next day, GW2580 at 10 mM in DMSO is diluted to 20 μM and 0.2% DMSO in medium containing 10% serum and serially diluted to yield a 10-point concentration curve. The M-NFS-60 cells are resuspended in medium at 0.5×106 cells/mL with 10% serum and 20 ng/mL mouse MCSF. Cells (50 μL) are added to each well containing inhibitor (50 μL), and, 3 days later, 10 μL of WST-1 reagent is added to each well. After a 4-h incubation, the absorbance is measured at 440 nm and growth calculated as the difference between wells with full medium and wells with depleted medium.

Animal Administration [1]
C57BL6 male mice (4-8 weeks old) are used for the study. 3LL cells (2×105 cells) and B16F1 cells (105 cells) are implanted subcutaneously above the right shoulder. Tumor size is measured by digital calipers as previously described. Mice are killed and tissues are analyzed at the ethical tumor size limit of 1 cm in diameter. For orthotopic implants, RM-1 cells (5×103 cells in 50% Matrigel) are surgically implanted in the dorsolateral prostate of C57BL/6 male mice as previously described. Mice are treated with control diluent (0.5% hydroxypropyl methylcellulose, 0.1% Tween20 in distilled H2O) or GW2580 by oral gavage beginning 1 day after tumor implantation. For clodronate liposome (Clodrolip) studies, mice are treated with PBS or Clodrolip at 0.2 mL per 25 g total body weight every third day beginning 2 days after tumor implantation. For DC101 studies, mice are treated with PBS control or 800 μg DC101 every other day (intraperitoneally). For combination studies, mice are treated with 160 mg/kg GW2580 daily and DC101 every other day beginning 1 day after tumor implantation.

Background on GW2580

GW2580 is a selective and orally bioavailable inhibitor of Colony-stimulating-factor-1 receptor (CSF-1R) with IC50 value of 30nM [1]

GW2580 has been demonstrated to be an extremely selective inhibitor for CSF-1R and has been hypothesized to bind to the DFG-out mode of CSF-1R, which might lock it into an inactive conformation [2] GW2580 has shown to inhibit epithelial cell-associated CSF-1 signaling, reduce Gr-1+ CD11b+ myeloid-derived suppressor cells (MDSCs) expansion, and alleviate the immune-suppressive microenvironment [3]. In addition, GW2580 suppressed IL-10 secretion in human glioblastoma cell line T98G [4].

Effects of the cFMS kinase inhibitor 5-(3-methoxy-4-((4-methoxybenzyl)oxy)benzyl)pyrimidine-2,4-diamine (GW2580) in normal and arthritic rats.[Pubmed:18434589]

J Pharmacol Exp Ther. 2008 Jul;326(1):41-50.

The cFMS (cellular homolog of the V-FMS oncogene product of the Susan McDonough strain of feline sarcoma virus) (Proc Natl Acad Sci U S A 83:3331-3335, 1986) kinase inhibitor 5-(3-methoxy-4-((4-methoxybenzyl)oxy)benzyl)pyrimidine-2,4-diamine (GW2580) inhibits colony-stimulating factor (CSF)-1-induced monocyte growth and bone degradation in vitro and inhibits CSF-1 signaling through cFMS kinase in 4-day models in mice (Proc Natl Acad Sci U S A 102:16078, 2005). In the present study, the kinase selectivity of GW2580 was further characterized, and the effects of chronic treatment were evaluated in normal and arthritic rats. GW2580 selectively inhibited cFMS kinase compared with 186 other kinases in vitro and completely inhibited CSF-1-induced growth of rat monocytes, with an IC(50) value of 0.2 microM. GW2580 dosed orally at 25 and 75 mg/kg 1 and 5 h before the injection of lipopolysaccharide inhibited tumor necrosis factor-alpha production by 60 to 85%, indicating a duration of action of at least 5 h. In a 21-day adjuvant arthritis model, GW2580 dosed twice a day (b.i.d.) from days 0 to 21, 7 to 21, or 14 to 21 inhibited joint connective tissue and bone destruction as assessed by radiology, histology and bone mineral content measurements. In contrast, GW2580 did not affect ankle swelling in the adjuvant model nor did it affect ankle swelling in a model where local arthritis is reactivated by peptidoglycan polysaccharide polymers. GW2580 administered to normal rats for 21 days showed no effects on tissue histology and only modest changes in serum clinical chemistry and blood hematology. In conclusion, GW2580 was effective in preserving joint integrity in the adjuvant arthritis model while showing minimal effects in normal rats.

Inhibition of colony-stimulating-factor-1 signaling in vivo with the orally bioavailable cFMS kinase inhibitor GW2580.[Pubmed:16249345]

Proc Natl Acad Sci U S A. 2005 Nov 1;102(44):16078-83.

Colony-stimulating-factor-1 (CSF-1) signaling through cFMS receptor kinase is increased in several diseases. To help investigate the role of cFMS kinase in disease, we identified GW2580, an orally bioavailable inhibitor of cFMS kinase. GW2580 completely inhibited human cFMS kinase in vitro at 0.06 microM and was inactive against 26 other kinases. GW2580 at 1 microM completely inhibited CSF-1-induced growth of mouse M-NFS-60 myeloid cells and human monocytes and completely inhibited bone degradation in cultures of human osteoclasts, rat calvaria, and rat fetal long bone. In contrast, GW2580 did not affect the growth of mouse NS0 lymphoblastoid cells, human endothelial cells, human fibroblasts, or five human tumor cell lines. GW2580 also did not affect lipopolysaccharide (LPS)-induced TNF, IL-6, and prostaglandin E2 production in freshly isolated human monocytes and mouse macrophages. After oral administration, GW2580 blocked the ability of exogenous CSF-1 to increase LPS-induced IL-6 production in mice, inhibited the growth of CSF-1-dependent M-NFS-60 tumor cells in the peritoneal cavity, and diminished the accumulation of macrophages in the peritoneal cavity after thioglycolate injection. Unexpectedly, GW2580 inhibited LPS-induced TNF production in mice, in contrast to effects on monocytes and macrophages in vitro. In conclusion, GW2580's selective inhibition of monocyte growth and bone degradation is consistent with cFMS kinase inhibition. The ability of GW2580 to chronically inhibit CSF-1 signaling through cFMS kinase in normal and tumor cells in vivo makes GW2580 a useful tool in assessing the role of cFMS kinase in normal and disease processes.

Description

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.
