Myrotoxin B is a macrocyclic trichothecene first isolated in 1985.[1] It was tested on Swiss mice and found to be very toxic, though not the most toxic of the three toxins that were tested at that time.[2] It has also been isolated from Myrothecium roridum, a pathogen leaf spot that affects mulberry, though it is unknown if it is used as a pathotoxin.[3]
