Cabazitaxel is an antineoplastic agent used in combination with corticosteroids to treat metastatic castration-resistant prostate cancer in patients previously treated with a docetaxel-containing treatment regimen.
Microtubules are cytoskeletal polymers that regulate cell shape, vesicle transport, cell signalling, and cell division. They are made up of alpha-tubulin and beta-tubulin heterodimers. Microtubules extend toward the mitotic spindle during mitosis to allow the separation and distribution of chromosomes during cell division. Cabazitaxel binds to the N-terminal amino acids of the beta-tubulin subunit and promotes microtubule polymerization while simultaneously inhibiting disassembly: this results in the stabilization of microtubules, preventing microtubule cell division. Cabazitaxel ultimately blocks mitotic and interphase cellular functions and tumour proliferation.
