Bufotoxin20

Bufotoxin20 is a potent neurotoxin produced by the venomous marine snail, Conus textile. It is one of the most toxic substances known to science, with an LD50 (lethal dose for 50% of subjects) of approximately 1 nanogram per kilogram of body weight in mice. This makes it roughly 100 times more toxic than cyanide. Bufotoxin20 acts by binding to voltage-gated sodium channels in nerve cells, leading to a prolonged depolarization and subsequent cell death. Its structure is characterized by a unique guanidine group and a complex ring system, which contribute to its high affinity for sodium channels.

The discovery of bufotoxin20 has significantly advanced our understanding of ion channel function and toxicity. It has been used as a research tool to study the molecular mechanisms of sodium channel blockade and to develop new therapeutic agents. However, due to its extreme toxicity, bufotoxin20 is not used in clinical practice and is primarily of interest to researchers in the fields of pharmacology and neurotoxicology.

Bufotoxin20 is also a subject of interest in the study of marine toxins and their potential as templates for the development of new pharmaceuticals. Its unique structure and mechanism of action make it a valuable tool for drug discovery. However, its extreme toxicity necessitates careful handling and storage, and its use is strictly regulated in many countries.
