Physical and Chemical Properties | Bioactive BLZ945 is an orally active, potent selective CSF-1R inhibitor with an IC50 of 1 nM, which is more than 1000 times more selective than its nearest receptor tyrosine kinase homolog. |
In vitro study | In bone marrow-derived macrophages (BMDMs), BLZ945 specific indications CSF-1-dependent propagation with EC50 of 67nM, and causes CSF-1R propagation. BLZ945 blocks. in bone marrow-derived macrophages (BMDMs), BLZ945 specifically inhibited CSF-1-dependent proliferation with an EC50 of 67nm and reduced phosphorylation by CSF-1R. BLZ945 blocks the interaction of macrophages and glioma cells in survival, proliferation and/or polarization, thereby inhibiting their pro-tumorigenesis. |
In vivo study | 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 carcinoma and kernel 14-expressing human papillomavirus type 16 (K14-HPV-16) transgenic model of cerical carcinoma. in glioma-bearing mice, BLZ945 blocked tumor progression and significantly improved survival by CSF-1R inhibition. BLZ945 also inhibits orthotopic tumor growth in vivo from patient-derived primitive neurospheres and cell lines. Virus intermediate T antigen (Virus) model of mammary tumor MMTV-PyMT-driven oncogenic breast cancer in mice, and keratin 14 expression in oncogenic human papillomavirus type 16 Virus (K14-HPV-16) in transgenic models, BLZ945 (200 mg/kg, p.o.) reduces the growth of malignant cells. |

in vitro studies
In bone marrow-derived macrophages (BMDMs), BLZ945 specifically inhibits CSF-1-dependent proliferation, EC50 is 67nM, and reduces CSF-1R phosphorylation. BLZ945 blocks the interaction of macrophages and glioma cells in survival, proliferation, and/or polarization, thereby inhibiting their pro-tumorigenesis.
In vivo studies
in glioma-loaded mice, BLZ945 blocked tumor development and significantly improved survival rate through CSF-1R inhibition. BLZ945 can also inhibit the growth of ortho-tumor cells and cell lines derived from patients. BLZ945 (200 mg/kg, p.o.) reduced the growth of malignant cells in mouse mammary tumor virus-driven polyomavirus intermediate T antigen (MMTV-PyMT) model and keratin -14-expressed human papillomavirus type 16 (K14-HPV-16) transgenic model.
