Allopumiliotoxin 267A

Allopumiliotoxin 267A is a toxin found in the skin of several poison frogs of the family Dendrobates.[1] It is a member of the class of compounds known as allopumiliotoxins. The frogs produce the toxin by modifying the original version, pumiliotoxin 251D.[2] It has been tested on mice and found to be five times more potent than the former version. It has been produced synthetically through a variety of different routes.[3][4][5][6]
