Background

Cevipabulin (TTI-237) is a new anti-microtubule agent [1][2][3][4].

Microtubules are a component of the cytoskeleton that participate in many crucial cellular functions, include maintaining the structure of the cell, forming the cytoskeleton and chromosome separation.

Cevipabulin (TTI-237) is a new anti-microtubule agent with antitumor activity. In COLO 205 cells, TTI-237 inhibited cell proliferation with IC50 value of 31 nM [1]. At low ratios of TTI-237: tubulin heterodimer (about 1:30), TTI-237 increased depolymerization kinetics in response to low temperature, but stabilized the aggregates at high ratios (about 1:4). TTI-237 inhibited the exchange of [3H]GTP at the exchangeable nucleotide site of the tubulin heterodimer [2]. Cevipabulin (TTI-237) increased tubulin polymerization. Cevipabulin was stable and water-soluble, and could be administered i.v. or p.o. in saline [3]. TTI-237 inhibited the binding of [3H]vinblastine to tubulin, but significantly increased turbidity development that more closely resembled the effect of docetaxel. In Hela cells, TTI-237 (34 nmol/L) induced multiple spindle poles and multi-nuclear cells. At 20-40 nmol/L, TTI-237 produced sub-G1 nuclei, while at > 50 nmol/L, TTI-237 induced G2-M block.

In athymic mice bearing LoVo human colon adenocarcinoma, TTI-237 exhibited good antitumor activity in a dose-dependent way. In mice bearing U87-MG human glioblastoma, TTI-237 (25 mg/kg) given both i.v. and p.o. were equally effective [4].
