Vincristine (leurocristine, Oncovin), sometimes abbreviated "VCR", is a kind of microtubule function inhibitor. Vincristine sulfate is the salt of an alkaloid from the flowering periwinkle plant (also known as Vinca rosea Linn). Vincristine sulfate induces apoptosis in human lymphoma cells. Vincristine binds to tubulin dimers, inhibiting assembly of microtubule structures. The IC50 and IC90 of vincristine for the 4 vaccine-associated feline sarcoma (VAFS) cell lines were between 0.005 to 0.039 µg/ml and 0.045 to 1.027 µg/ml, respectively.

| ABT-751
ABT-751 is an orally bioavailable tubulin inhibitor with IC50 of about 1.5 and 3.4 µM in neuroblastoma and non-neuroblastoma cell lines, respectively. |
| Docetaxel
Docetaxel (Taxotere), a semi-synthetic analog of paclitaxel (Taxol), is a promoter of microtubule polymerization leading to cell cycle arrest at G2/M, apoptosis and cytotoxicity. |
| Paclitaxel
Paclitaxel is a diterpenoid derived from the bark of the plant Picea abies, and is also a microtubule polymer stabilizer, which promotes polymerization of microtubule proteins to inhibit depolymerization, maintains the stability of microtubule proteins, and inhibits cellular mitosis, and acts on human endothelial cells with an IC50 of 0.1 pM. |
