Infobox references

Plinabulin (NPI-2358) is an experimental cancer drug. It is a synthetic analog of the natural compound phenylahistin.^[1] Plinabulin interrupts tumor blood flow via disruption of the tumor's vascular endothelial cells resulting in tumor necrosis.^[2]^[3] It also has a tubulin-depolymerizing activity.^[4]

It has undergone Phase I and Phase II clinical trials for non-small cell lung cancer.^[5]^[6]
