Territrem B is an α-pyrone tremorgenic mycotoxin first identified from an Aspergillus terreus strain by Ling and colleagues at Taiwan National University in 1979. Territrem B is a potent insecticide acting via irreversible inhibition of acetylcholinesterase (AChE). The binding mechanism is very different from typical irreversible AChE inhibitors like neostigmine and the organophospates.
