Chiauranib (CS2164) 是一种针对肿瘤血管生成的具有口服活性的多靶点抑制剂。Chiauranib 有效抑制血管生成相关激酶 (VEGFR1,VEGFR2,VEGFR3,PDGFRα和c-Kit),有丝分裂相关激酶Aurora B和慢性炎症相关激酶CSF-1R,IC50值为 1-9 nM。Chiauranib 具有很强的抗癌作用。
生物活性 | Chiauranib (CS2164) is an orally active multi-target inhibitor against tumor angiogenesis. Chiauranib potently inhibits the angiogenesis-related kinases (VEGFR1,VEGFR2,VEGFR3,PDGFRαandc-Kit), mitosis-related kinaseAurora B, and chronic inflammation-related kinaseCSF-1R, withIC50values ranging from 1-9 nM. Chiauranib has strongly anticancer effects[1]. |
IC50& Target[1] | Flt-1 8 nM (IC50) | KDR 7 nM (IC50) | Flt-4 9 nM (IC50) | PDGFRα 1 nM (IC50) | Aurora B 9 nM (IC50) | PDGFRβ 93 nM (IC50) | c-Kit 4 nM (IC50) | CSF-1R 7 nM (IC50) |

体外研究 (In Vitro) | Chiauranib (CS2164; 3 μM; 24 hours) shows induction of G2/M cell cycle arrest and suppression of cell proliferation in tumor tissues through the inhibition of Aurora B-mediated H3 phosphorylation[1]. In HUVEC and PDGFRβ phosphorylation in PDGFRβ overexpressed NIH3T3 cells, Chiauranib (CS2164; 0.03-3 μM) displays anti-angiogenic activities through suppression of VEGFR/PDGFR phosphorylation, inhibition of ligand-dependent cell proliferation and capillary tube formation, and prevention of vasculature formation in tumor tissues[1]. .
Chiauranib (CS2164) inhibits CSF-1R phosphorylation that leads to the suppression of ligand-stimulated monocyte-to-macrophage differentiation and reduces CSF-1R+cells in tumor tissues[1].
Cell Cycle Analysis[1] Cell Line: | Molt-4 cells | Concentration: | 3 μM | Incubation Time: | 24 hours | Result: | Induced the pronounced cell cycle arrest in the G2/M phase at 3 μM. |
Western Blot Analysis[1] Cell Line: | Molt-4 cells | Concentration: | 1.5 μM, 3 μM, 6 μM | Incubation Time: | 24 hours | Result: | Yielded a substantial reduction in the level of p-H3 in Molt‐4 cells in a concentration-dependent fashion. |

体内研究 (In Vivo) | Chiauranib (CS2164; 0.5-40 mg/kg; oral administration; once daily; for 33 days or 43 days) treatment induces remarkable regression or complete inhibition of tumor growth at well-tolerated oral doses in several human tumor xenograft models. Chiauranib exhibits broad and potent in vivo anti-tumor activities[1].
Animal Model: | Female BALB/c athymic (nu+/nu+) mice (6-week old) bearing HCT-8, SMMC-7721, MGC‐803 or A549 cells[1] | Dosage: | 2.5 mg/kg, 5 mg/kg, 10 mg/kg, 20 mg/kg, 40 mg/kg | Administration: | Oral administration; once daily; for 33 days or 43 days | Result: | Induced remarkable regression or complete inhibition of tumor growth in several human tumor xenograft models. |
