6、s through binding to the soluble tubulin heterodimer, the major component of the microtubule.The Colchicine binding abilities of tubulins from a variety of sources are summarized, and the mechanism ofColchicine binding to brain tubulin is explored in depth. The relationship between colchicinoid stru
