Effects of synthetic compounds similar to the structure of a spider toxin were studied on the glutamate receptors in crustacean neuromuscular synapses. Two kinds of analogues, 2,4-dihydroxyphenylacetyl-asparaginyl cadaverine (C-1) and 2,4-dihydroxyphenylacetyl-asparaginyl spermine (C-2), suppressed the excitatory postsynaptic potentials in a manner similar to natural spider toxin (JSTX). The dose-response relationship showed that the relative potency of the compounds is C-1 less than C-2 less than JSTX. While the effect of JSTX was irreversible, those of C-1 and C-2 were reversible. These synthetic compounds may serve as important tools in studying the structure and function of glutamate receptors.

D005071 Evoked Potentials Electrical responses recorded from nerve, muscle, SENSORY RECEPTOR, or area of the CENTRAL NERVOUS SYSTEM following stimulation. They range from less than a microvolt to several microvolts. The evoked potential can be auditory (EVOKED POTENTIALS, AUDITORY), somatosensory (EVOKED POTENTIALS, SOMATOSENSORY), visual (EVOKED POTENTIALS, VISUAL), or motor (EVOKED POTENTIALS, MOTOR), or other modalities that have been reported.

D001216 Asparagine A non-essential amino acid that is involved in the metabolic control of cell functions in nerve and brain tissue. It is biosynthesized from ASPARTIC ACID and AMMONIA by asparagine synthetase. (From Concise Encyclopedia Biochemistry and Molecular Biology, 3rd ed) L-Asparagine
D013096 Spermine A biogenic polyamine formed from spermidine. It is found in a wide variety of organisms and tissues and is an essential growth factor in some bacteria. It is found as a polycation at all pH values. Spermine is associated with nucleic acids, particularly in viruses, and is thought to stabilize the helical structure.
