Combretastatin A-1 phosphate (OXi-4503) tetrasodium, a prodrug of Combretastatin A-1, is a tubulin-binding microtubule polymerization inhibitor that targets the colchicine-binding site. By inducing tubulin depolymerization, Combretastatin A-1 phosphate tetrasodium inhibits the Wnt β-catenin pathway and leads to the deactivation of AKT. It possesses both anti-tumor and anti-vascular properties.

Epothilone B (EPO 906) 是微管稳定剂，Ki 为0.71 μM。 它与αβ-微管蛋白异二聚体亚基结合，使αβ-微管蛋白解离减少。

Epofolate is folate receptor-targeting antimitotic agent with potential antineoplastic activity. Folate receptor-targeted epothilone BMS753493 contains an epothilone moiety linked to a single folate molecule. Mediated through the folate moiety, this agent delivers the antimitotic epothilone component into cells expressing folic acid receptors, frequently upregulated in many types of tumor cells. After ligand-receptor internalization, the epothilone moiety induces microtubule polymerization and stabilizes microtubules against depolymerization, resulting in the inhibition of mitosis and cellular proliferation. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus).

Iso-Fludelone is the third-generation epothilone B analogue with potential anti-mitotic and antineoplastic activites. Iso-fludelone binds to tubulin and induces microtubule polymerization and stabilizes microtubules against depolymerization, which may result in the inhibition of cell division, the induction of G2 M arrest, and apoptosis. Compared to other generations of epothilones, iso-fludelone exhibits increased stability, water solubility, potency, duration of action, tumor penetration as well as reduced toxicity. In addition, this agent is a not a substrate of the P-glycoprotein (P-gp), a multidrug resistance pump often overexpressed in cancer cells. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus).

E7974 is an analog of the sponge-derived anti-microtubule tripeptide hemiasterlin with antimitotic and potential antineoplastic activities. Hemiasterlin analog E7974 binds to the Vinca domain on tubulin, resulting in inhibition of tubulin polymerization and microtubule assembly; depolymerization of exsiting microtubules; inhibition of mitosis; and inhibition of cellular proliferation. This agent may have more affinity for the beta-3 tubulin isotype. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus).

Sagopilone is a fully synthetic low-molecular-weight epothilone with potential antineoplastic activity. Sagopilone binds to tubulin and induces microtubule polymerization while stabilizing microtubules against depolymerization, which may result in the inhibition of cell division, the induction of G2 M arrest, and apoptosis. The agent is not a substrate for the P-glycoprotein (P-gp) efflux pump and so may exhibit activity in multidrug-resistant (MDR) tumors. The epothilone class of metabolites was originally isolated from the myxobacterium Solangium cellulosum.

Cemadotin hydrochloride is the salt from of Cemadotin (free base), also known as, LU103793, a mitosis inhibitor potentially for the treatment of solid tumours. Cemadotin is also a synthetic derivative of Dolastatin 15, an antiproliferative compound which was isolated from the mollusk Dolabella auricularia. Like Dolastatin 15, LU103793 is highly cytotoxic in vitro (IC50 = 0.1 nM). LU103793 inhibits microtubule polymerization in a concentration-dependent manner (IC50 = 7 microM). Treatment with this compound also induced depolymerization of preassembled microtubules. Cell cycle analysis of tumor cell lines treated with LU103793 indicated a block in the G2-M phase.

Cabazitaxel-d6 is a deuterium labeled cabazitaxel. Cabazitaxel is a semi-synthetic derivative of the natural taxoid 10-deacetylbaccatin III with potential antineoplastic activity. Cabazitaxel binds to and stabilizes tubulin, resulting in the inhibition of microtubule depolymerization and cell division, cell cycle arrest in the G2 M phase, and the inhibition of tumor cell proliferation. Unlike other taxane compounds, this agent is a poor substrate for the membrane-associated, multidrug resistance (MDR), P-glycoprotein (P-gp) efflux pump and may be useful for treating multidrug-resistant tumors. In addition, cabazitaxel penetrates the blood-brain barrier (BBB).

KOS-1584 is a second-generation epothilone with potential antineoplastic activity. Epothilone KOS-1584 binds to tubulin and induces microtubule polymerization and stabilizes microtubules against depolymerization, which may result in the inhibition of cell division, the induction of G2 M arrest, and apoptosis. Compared to first-generation epothilones, this agent exhibits greater safety and efficacy with an enhanced pharmaceutical profile, including enhanced water solubility and tumor penetration, and reduced CNS exposure. In addition, epothilone KOS-1584 is a poor substrate for the P-glycoprotein (P-gp) drug efflux pump.
