NCIt definition : An orally active diketopiperazine derivative with potential antineoplastic activity.
Plinabulin selectively targets and binds to the colchicine-binding site of tubulin,
thereby interrupting equilibrium of microtubule dynamics. This disrupts mitotic spindle
assembly leading to cell cycle arrest at M phase and blockage of cell division. In
addition, plinabulin may also inhibit growth of proliferating vascular endothelial
cells, thereby disrupting the function of tumor vasculature that further contributes
to a decrease in tumor cell proliferation.;
