Phenylahistin is a metabolite produced by the fungus Aspergillus ustus[1] that belongs to a class of naturally occurring 2,5-diketopiperazines featuring a dehydrohistidine residue that exhibit important biological activities, such as anti-cancer or neurotoxic effects.[2]

Phenylahistin is a microtubule binding agent that exhibits cytotoxic activities against a wide variety of tumor cell lines.[3] A series of synthetic analogs were prepared to remove the chirality and optimize biological activity. These studies led to the potent anti-tumor agent plinabulin, which is active in multidrug-resistant (MDR) tumor cell lines.[4]
