生物活性

Eribulin mesylate (E7389 mesylate) is a microtubule targeting agent that is used for the research of metastatic breast cancer. Eribulin mesylate inhibits the proliferation of cancer cells by binding microtubule proteins and microtubules.

体外研究

Eribulin (1-100 nM; 72 h) inhibits cells proliferation, with IC50s of 22.8 and 21.5 nM for LM8 and Dunn cells, respectively.
Eribulin (10-50 nM; 12-72 h) increases early apoptosis significantly after 24 h treatment at the dose of 50 nM in LM8 cells.
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.
Eribulin (1-50 nM; 12 h) does not induce senescence in LM8 cells.
Eribulin (1-10 nM; 16 h) induces morphological change and suppresses cell migration in a low concentration in LM8 cells.

Cell Proliferation Assay

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

Cell Line: LM8 cells
Concentration: 0, 10, 50 nM
Incubation Time: 12, 24, 48, 72 hour
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

Cell Line: LM8 cells
Concentration: 0, 10, 50 nM
Incubation Time: 12, 24, 48, 72 hour
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
