Microtubule

ELR510444 has potent microtubule-disrupting activity, causing a loss of cellular microtubules and the formation of aberrant mitotic spindles and leading to mitotic arrest and apoptosis of cancer cells. ELR510444 potently inhibits cell proliferation with an IC(50) value of 30.9 nM in MDA-MB-231 cells, inhibits the rate and extent of purified tubulin assembly, and displaces colchicine from tubulin, indicating that the drug directly interacts with tubulin at the colchicine-binding site. ELR510444 is not a substrate for the P-glycoprotein drug transporter and retains activity in βIII-tubulin-overexpressing cell lines, suggesting that it circumvents both clinically relevant mechanisms of drug resistance to this class of agents.

ELR510444 shows potent antitumor activity in the MDA-MB-231 xenograft model. A low concentration of ELR510444 (30 nM) rapidly alters endothelial cell shape.
