Tarichatoxin
Taicatoxin (TCX) is a snake toxin that blocks voltage-dependent L-type calcium channels and small conductance Ca -activated K channels. The name taicatoxin (TAIpan + CAlcium + TOXIN) is derived from its natural source, the taipan snake, the site of its action, calcium channels, and from its function as a … See more Through SDS-PAGE analysis, TCX (112154-17-3 ) was determined to be a complex held together by non-covalent forces of the following three polypeptides in a stoichiometry of 1:1:4 respectively: • a … See more A dose of 1 to 2 μg of taicatoxin can kill a mouse of 20 g in 2 hours.

WebBatrachotoxin (BTX) is an extremely potent cardio-and neurotoxic steroidal alkaloid found in certain species of beetles, birds, and frogs. The name is from the Greek word βάτραχος, bátrachos, 'frog'. Structurally-related chemical compounds are often referred to collectively as batrachotoxins. In certain frogs, this alkaloid is present mostly on the skin.
WebThese newts mostly have Tarichatoxin and Tetrodotoxin (TTX). This type of toxin is the same as found in puffer fish and the notorious blue ring octopus. TTX is the most poisonous non-protein substance known to man. When ingested into the body, this toxin directly attacks the nervous system and causes muscle paralysis, which can cause cardiac ...
