Chemical Taxonomy
Description belongs to the class of organic compounds known as gelsemium alkaloids. These are alkaloids with a structure that is based on the tetracyclic gelsemium skeleton. These alkaloids contain an oxindole function and a cage-like, hydroaromatic residue which is believed to arise from an intermediate related to anhydrovobasinediol by formation of a 6,20 bond and rearrangement to an oxindole. The major alkaloids in this group are related to Gelsemine; however, a smaller group, characterized by Gelsedine, lack the 6,20 bond, and have also lost C-21.

Toxicity Profile
Route of ExposureNot Available
Mechanism of ToxicityGelsemine has convulsant effects with a similar mechanism of action to strychnine. Strychnine is a neurotoxin which acts as an antagonist of glycine and acetylcholine receptors. It primarily affects the motor nerves in the spinal cord which control muscle contraction. An impulse is triggered at one end of a nerve by the binding of neurotransmitters to the receptors. In the presence of a neuroinhibitor, such as glycine, a greater quantity of excitatory neurotransmitters must bind to receptors before there will be an action potential generated. Glycine acts primarily as an agonist of the glycine receptor, which is a ligand-gated chloride channel in neurons located in the spinal cord and in the brain. This chloride channel will allow the negatively charged chloride ions into the neuron, causing a hyperpolarization which pushes the membrane potential further from threshold. Strychnine is an antagonist of glycine, which means it binds to the same receptor, preventing the inhibitory effects of glycine on the postsynaptic neuron. Therefore, action potentials are triggered with lower levels of excitatory neurotransmitters. When the inhibitory signals are prevented, the motor neurons do will be more easliy activated and the victim will have spastic muscle contractions. Structure of strychnine in complex with ACh binding protein (AChBP). Strychnine is also an antagonist for acetylcholine receptors, which is known to be homologous to the glycine receptor. (Wikipedia)
