It:Histrionicotoxin

2006-12-11T16:58:53Z

Ghb05:

Histrionicotoxin is a poison. In 1823 Captain Charles Stuart Cochrane discovered tribes of Indians native to Colombia using it for hunting. They used the poison for the tips of their arrows and blowguns. He discovered that the poison was extracted from small yellow brightly coloured frogs called Dendrobates histrionicus.

==Uses==

They have been found to be potent inhibitors of the acetyl choline receptor channel and as such constitute important synthetic targets.
