      Dimethylenastron is an Eg5 inhibitor, which arrests cells with monopolar spindles to which all chromosomes attach in a syntelic manner.;Target: Eg5;In vitro: Growth of HUVECs and LECs is inhibited by dimethylenastron (DMN) in a dose- and time-dependent manner. [2] MedChem Express HY-19944
      Enzymes Tocris Bioscience 5261
      Inhibitor of mitotic motor kinesin Eg5 Tocris Bioscience 5261
      Inhibitor of mitotic motor kinesin Eg5 (IC50 = 200 nM). Arrests mitosis, triggers apoptosis and up-regulates Hsp-70 expression in multiple human myeloma cell lines. Also inhibits the growth of several types of cancer cell lines (EC50 values are 330, 603, 743 and 881 nM in HCT116, Htert-HME1, BxPC3, K562 and NCI-H1299 cancer cells, respectively). Suppresses the migration and invasion of PANC1 cells in vitro. Cytoprotective. Tocris Bioscience 5261
