Simotaxel is a microtubule-stabilizing agent that acts as an orally active derivative of the taxane class. It binds to β-tubulin, promoting tubulin polymerization with an EC₅₀ of 0.9 μM, while inhibiting tubulin depolymerization and causing cell cycle arrest in the G₂-M phase. Additionally, Simotaxel disrupts mitotic spindle formation and activates the caspase-dependent apoptotic pathway. This compound is particularly relevant for research into Paclitaxel- and Docetaxel-resistant solid tumors, demonstrating inhibitory effects on cell lines sensitive to these treatments.
