Tubulin-IN-53

Tubulin-IN-53 is a potent inhibitor of microtubulin (Tubulin) with an IC50 of 6.06 μM. By targeting the colchicine binding site on tubulin, Tubulin-IN-53 hinders tubulin polymerization, disrupting the microtubule network. It induces cell cycle arrest at the G2/M phase and apoptosis (apoptosis) in MCF-7 cells, while inhibiting cell migration. This compound also leads to a reduction in mitochondrial membrane potential and an increase in reactive oxygen species (ROS) accumulation. Additionally, Tubulin-IN-53 disrupts angiogenesis in human umbilical vein endothelial cells and is applicable in research on cancers such as breast and lung cancer.
