Product ID L8401-50UG 
Molecular formula C29H52O6N10

It is an antagonist of glutamate receptors by blocking glutamate-activated postsynaptic ion channels.

Polyamine , from Argiope lobata spider venom
Biological activity

It has a reversible postsynaptic blocking effect: 50% decrease of excitatory postsynaptic current (EPSC) amplitude, at 4.4 x 10-7 M concentration in insect neuro-muscular preparations and 1.6 x 10-5 M in frog preparations.
In isolated frog spinal cord preparations, it inhibits glutamate-induced depolarizations of motoneurons, while having no effect on aspartate-induced responses.
Argiotoxin 636 reduces excitatory potentials at insect synapses that are thought to be mediated by non-NMDA receptors.
Argiotoxin 636 appears to act as an open-channel blocker of the NMDA-activated ion channel in mammalian neurons.
