Name Mode of Action References
Colchicine Antimitotic agent that disrupts microtubules by binding to tubulin and preventing its polymerization; induces apoptosis in several normal and tumor cell lines. [113]
Dolastatin 15 Reported to interact with tubulin and induce apoptosis [114]
Nocodazole Antimitotic agent that binds to β tubulin and disrupts mitotic spindle function; Induces apoptosis in several normal and tumor cell lines. [115]
Paclitaxel Binds to β tubulin and promotes the formation of highly stable microtubules that resist depolymerization, preventing cell division. [116]
Podophyllotoxin Inhibits microtubule assembly. [117]
Rhizoxin Binds to β tubulin in most eucaryotic cells including animals, plants and fungi. It completely prevents formation of an intrachain crosslink in β tubulin by N,N'ethylenebis(iodoacetamide). [118]
Vinblastine Antimitotic agent. Inhibits microtubule assembly by binding tubulin and inducing self association; depolymerizes preexisting microtubules. Induces apoptosis in several tumor cell lines. [119]
Vinorelbine (Navelbine) Potent antimitotic, antitumor agent. Low neurotoxicity is related to its higher affinity for mitotic microtubules than for axonal microtubules. [119]
