PubMed Abstract: Isoflavones possess many biological activities, including anti-inflammatory and anticancer effects. Microtubules (composed of αβ-tubulin heterodimers) are described as one possible cellular target of some of these isoflavones. However, the binding of tubulin to isoflavones has not been extensively studied, and until now, no crystal structure of the tubulin-isoflavone complex has been solved, and details of the isoflavone-tubulin interaction remain elusive.
