CSF1R c.1085A>G genetic variant confers the sensitivity of macrophage survival to CSF-1R inhibitors. Macrophages differentiated from peripheral blood mononuclear cells were incubated with various concentrations of the CSF-1R inhibitor, BLZ945 (B) for 8 days Percentage of cell survival was determined by CellTiter-Glo® Luminescent Cell Viability Assay.

C, we evaluated the effects of CSF-1R inhibitor BLZ945 (500 nmol/L) or GW2580 (1 μmol/L) on the phenotypic changes of tumor-educated monocytes. D, the direct effects of BLZ945 on phenotypes of human primary monocytes were demonstrated. *, P < 0.05; **, P < 0.01; nonparametric Mann–Whitney U test.

|Description||BLZ945 is an orally active, potent and selective CSF-1R inhibitor with IC50 of 1 nM, >1000-fold selective against its closest receptor tyrosine kinase homologs.|
In bone marrow-derived macrophages (BMDMs), BLZ945 specifically inhibits CSF-1-dependent proliferation with EC50 of 67nM, and decreases CSF-1R phosphorylation. BLZ945 blocks the reciprocal effects between macrophages and glioma cells on the survival, proliferation and/ or polarization of each other to promote tumorigenesis. 
|In vivo||In glioma-bearing mice, BLZ945 blocks tumor progression and significantly improves survival via CSF-1R inhibition. BLZ945 also inhibits orthotopic tumor growth of patient-derived proneural tumor spheres and cell lines in vivo.  BLZ945 (200 mg/kg, p.o.) decreases the growth of malignant cells in both mouse mammary tumor virus-driven polyomavirus middle T antigen (MMTV-PyMT) model of mammary carcinogenesis and keratin 14-expressing human papillomavirus type 16 (K14-HPV-16) transgenic model of cervical carcinogenesis. |

For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.

Frequently Asked Questions
Does this molecule bind to any neurogenesis inhibiting enzymes? Which of the csf1r inhibitors is the most specific?
The IC50 of this compound to CSF1R is about 0.001uM, C-Kit 3.2uM and PDGFR-β 4.8uM. So it is relative specific to CSF1R.
We want to deliver the drug by oral gavage to mice, can you provide some advice about formulation?
S7725 BLZ945 can be dissolved in 0.5% CMC Na+1% Tween 80 at 20 mg/ml as a suspension.
