Mechanism of action

Paclitaxel is a microtubule-stabilizing agent that binds to the β-tubulin subunit of microtubules and prevents their disassembly. This stabilization disrupts the dynamic reorganization of the microtubule cytoskeleton required for cell division, trapping cells in mitosis and triggering apoptosis. It is one of the most widely used chemotherapy agents across multiple solid tumor types.
