Description: Cevipabulin (free base), also known as TTI-237, an antimicrotubule agent, is a small synthetic molecule of triazolopyrimidine derivative with potential antitumor activity. With a novel mechanism of action distinct from the action of other vinca alkaloid compounds, TTI-237 specifically binds to tubulin at the vinca site, and promotes the polymerization of tubulin into microtubules. TTI-237 stabilizes tubulin and inhibits microtubule disassembly. This results in cell cycle arrest at the G2/M phase, and leading to cell death.
