Ziconotide Acetate (107452-89-1 free base) (Prialt) is an analgesic agent and has been used to treat neuropathic and non-neuropathic pain. Ziconotide Acetate (107452-89-1 free base) acts by binding to N-type calcium channels situated on the terminal part of primary afferent neurons of the nociceptive pathway therefore reducing synaptic transmission with potent antinociceptive effects.

ω-Conotoxin MVIIC TFA is a peptide and neurotoxin with 26 residues that preferentially blocks P-type and Q-type Ca ++ currents by binding with high affinity to voltage-sensitive neuronal Ca ++ channels (VGCCs) and can be radiolabeled and used in immunoprecipitation assays.

Scyllatoxin (Leiurotoxin I), a peptide toxin derived from the venom of the scorpion (Leiurus quinquestriatus hebraeus), acts as a blocker of small-conductance K Ca (SK) channels. It notably enhances the release of norepinephrine (NE) and epinephrine (Epi) in vivo [1].

Tamapin, a venom peptide isolated from the Indian red scorpion (Mesobuthus tamulus) [1], selectively targets and blocks small-conductance Ca(2+)-activated K(+) (SK) channels, particularily SK2 (Potassium Channel). It inhibits SK channel-mediated currents in the pyramidal neurons of the hippocampus.

Tamapin TFA, a venom peptide isolated from the Indian red scorpion (Mesobuthus tamulus) [1], selectively targets and blocks small conductance Ca(2+)-activated K(+) (SK) channels, particularly the SK2 subtype (Potassium Channel). It is known to inhibit SK channel-mediated currents in the hippocampal pyramidal neurons.

ω-Conotoxin FVIA is an inhibitor of N-type Ca²⁺ channels (Caᵥ2.2), shown to alleviate mechanical and thermal pain abnormalities in a rat model of caudal nerve injury. This compound has potential utility in the research of potent analgesics with minimal side effects [1].

ω-Conotoxin CVIF is a selective inhibitor of Ca v 2.2 channels, with an IC50 value of 34.3 nM in isolated rat DRG neurons, and exhibits weakly reversible blockade of Cav2.2 channels [1].

ω-Conotoxin CVIE selectively inhibits voltage-gated Ca^2+ channels (Ca_v 2.2) [1].

Myomodulin is a neuropeptide present in molluscs, insects, and gastropods. Within these organisms, myomodulin A specifically occurs in two identified Aplysia neurons: the ARC motor neuron [B16] and the abdominal neuron [L10].
