生物活性 | Eribulin (E7389) is amicrotubuletargeting agent that is used for the research of metastatic breastcancer. Eribulin inhibits the proliferation ofcancercells by binding microtubule proteins and microtubules. |
体外研究 (In Vitro) | Eribulin (1-100 nM; 72 h) inhibits cells proliferation, with IC50s of 22.8 and 21.5 nM for LM8 and Dunn cells, respectively[1]. Eribulin (10-50 nM; 12-72 h) increases early apoptosis significantly after 24 h treatment at the dose of 50 nM in LM8 cells[1]. Eribulin (10-50 nM; 12-72 h) induces G2/M arrest by 12 h treatment with at the dose of 50 nM, but not by long-term treatment (72 h) with 10 nM in LM8 cells[1]. Eribulin (1-50 nM; 12 h) does not induce senescence in LM8 cells[1]. Eribulin (1-10 nM; 16 h) induces morphological change and suppresses cell migration in a low concentration in LM8 cells[1].
Cell Proliferation Assay[1] Cell Line: | LM8 cells and Dunn cells | Concentration: | 0, 1, 10, 100 nM | Incubation Time: | 72 hours | Result: | Inhibited cells proliferation in a dose-dependent manner. |
Apoptosis Analysis[1] Cell Line: | LM8 cells | Concentration: | 0, 10, 50 nM | Incubation Time: | 12, 24, 48, 72 hours | Result: | Induced early apoptosis after 12 h at the concentration of 50 nM. Not detected apoptosis at the concentration of 10 nM. |
Cell Cycle Analysis[1] Cell Line: | LM8 cells | Concentration: | 0, 10, 50 nM | Incubation Time: | 12, 24, 48, 72 hours | Result: | Induced G2/M arrest by 12 h treatment with 50 nM. No G2/M arrest was induced by10 nM treatment. |

体内研究 (In Vivo) | Eribulin (1 mg/kg; i.v. once a week for 2 weeks) reduces primary tumor growth and lung metastasis of osteosarcoma in mice[1]. Eribulin (1 mg/kg; once i.v.) suppresses circulating tumor cells (CTC) appearance in the low-concentration phase[1].
Animal Model: | C3H/HeN mice (4-week-old) are injected LM8 cells[1] | Dosage: | 1 mg/kg | Administration: | I.v. once a week for 2 weeks | Result: | Suppressed primary tumor growth and induced apoptosis in tumor cells.
Reduced lung metastasis. Decreased the body weights. |
