| In Vitro | Monastrol is a small, cell-permeable molecule that arrests cells in mitosis by specifically inhibiting Eg5, a member of the Kinesin-5 family. Monastrol treatment of dividing cells results in spindle collapse and cell cycle arrest with a monoastral spindle, which is similar to the phenotype observed when Eg5 is inhibited by anti-Eg5 antibodies[1]. Monastrol is an allosteric inhibitor of the mitotic kinesin Eg5 that exhibits an antiproliferative effect against several cell lines. Monastrol treatment can decrease cell viability in MCF-7 tumor cells. Real-time cell growth kinetic analysis showed a decrease in the proliferation of MCF-7 cells exposed to monastrol[2]. |
| Cell Assay | The cytotoxicity assay is performed with MTT. Cells are seeded in 96-well culture plates (5000 cells/well) and incubated for 24 h for stabilization. After this period, the following treatments are administered for 24 and 48 h: vehicle control (0.5 % DMSO); 1 μM doxorubicin and monastrol at 5, 25, 50, 75, and 100 μM. After each time of treatment, the medium is withdrawn, serum-free media containing 0.5 mg/mL MTT salt is added and incubated for 4 h, and formazan crystal products are diluted[2]. |
