  • 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.

Biological Activity

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.
Targets
CSF-1R [1]
(Cell-free assay)
1 nM
In vitro

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. [1]

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. [1] 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.

Protocol

Cell Research:[1]
+ Expand
  • Cell lines: Glioma cell lines, BMDM, CRL-2467, HUVEC and HBMEC cell lines
  • Concentrations: ~6700 nM
  • Incubation Time: 96 hours
  • Method: Cell growth rate is determined using the MTT cell proliferation kit. Briefly, cells are plated in triplicate in 96-well plates: 1,000 cells per well for glioma cell lines, 5 x 1,000 cells per well for BMDM and CRL-2467, and 2.5 x 1,000 cells per well for HUVEC and HBMEC cell lines. For all experiments, media is changed every 48 h. Cells are grown in the presence or absence of 6.7–6,700 nM of BLZ945, or 8 μg/mL of CSF-1R neutralizing antibody. BMDM and CRL-2467 cells were supplemented with 10 ng/mL and 30 ng/ mL recombinant mouse CSF-1, respectively. Reduction of the MTT substrate is detected by colorimetric analysis using a plate reader as per the manufacturer’s protocol, and measured at 595 nm and 750 nm on a spectraMax 340pc plate reader.

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

  • Question 1:

    Does this molecule bind to any neurogenesis inhibiting enzymes? Which of the csf1r inhibitors is the most specific?

  • Answer:

    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.

  • Question 2:

    We want to deliver the drug by oral gavage to mice, can you provide some advice about formulation?

  • Answer:

    S7725 BLZ945 can be dissolved in 0.5% CMC Na+1% Tween 80 at 20 mg/ml as a suspension.
