Batrachotoxin is an alkaloidal steroid toxin found in the exudate from the skin of dart-poison frogs that are indigenous to Central and South America, and in feathers and skin of birds of the genus Pitohui living in New Guinea.

It is an extremely poisonous alkaloid. The batrachotoxin increases the permeability of the outer membrane of nerve and muscle cells to sodium ions. (−)-Batrachotoxin is a highly toxic alkaloid first found on poison-dart frogs in South America. 0000019936 00000 n

Batrachotoxin has no current clinical uses for two primary reasons. [10] The work presented here is a reflection of our strategy towards the synthesis of steroidal skeleton of batrachotoxin 1 by the application of radical mediated cascade cyclization.

Batrachotoxin is an important research tool in pharmacology because of its action of holding voltage-gated sodium channels open as well as its specific effects at other ligand-binding sites. Finally, a desire to synthesize aconitine, with its heavily oxygenated frame, has compelled us to seek selective methods for C–H hydroxylation in addition to new, convergent means for poly-carbocyclic ring construction. 0000012682 00000 n
