Research Overview
Conantokin-G
Research has shown conantokin-G can suppress NMDA-mediated responses in a sequence- and modification-dependent manner. It remains a classic marine peptide tool for probing glutamatergic signaling and analgesia-related pathways.
Huwentoxin-IV
Studies show huwentoxin-IV can inhibit sodium-channel currents with notable selectivity, making it useful for dissecting pain-sensing neuron excitability. It is one of the better known spider-venom templates for Nav1.7-targeted drug discovery.
