Mechanism of action

Vincristine works by binding to tubulin and preventing the formation of microtubules, which are essential for cell division. This leads to cell cycle arrest and apoptosis in rapidly dividing cancer cells. Topotecan, on the other hand, inhibits topoisomerase I, an enzyme that unwinds DNA during replication. By inhibiting this enzyme, Topotecan prevents DNA replication and induces apoptosis in cancer cells.
