What is Plinabulin?

Plinabulin is an orally active diketopiperazine derivative that binds to the colchicine-binding site of tubulin, disrupting microtubule dynamics and mitotic spindle assembly. This leads to cell cycle arrest and blocks tumor cell division. It may also inhibit vascular endothelial cell growth, disrupting tumor vasculature. It is studied in non-small cell lung cancer.
