| | territrem B Usage And Synthesis |
| Description | Territrem B (TRB) is a fungal metabolite isolated from Aspergillus terreus shown previously to be a potent and irreversible inhibitor of acetylcholinesterase (AChE). | | Description | Territrem B is a mycotoxin originally isolated from A. terreus that irreversibly inhibits acetylcholinesterase (AChE; IC50 = 19 nM for the electric eel enzyme). It is toxic to mice, inducing tremors with a median tremulous dose of 0.21 mg/kg, and has an LD50 value of 9.06 mg/kg. | | Uses | 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. | | Uses | Territrem B is a potent and irreversible inhibitor of acetylcholinesterase. | | Biological Activity | Territrem B is a mycotoxin originally isolated from A. terreus that irreversibly inhibits acetylcholinesterase (AChE; IC50 = 19 nM for the electric eel enzyme).
