    ω-Hexatoxin-Hv1a

    ω-ACTX-Hv1; ω-Atracotoxin-HV1

    		 Insecticide Calcium Channel Apoptosis Necroptosis Cardiovascular Disease Neurological Disease Inflammation/Immunology
    ω-Hexatoxin-Hv1a (ω-ACTX-Hv1; ω-Atracotoxin-HV1) is an orally active insecticidal neurotoxin containing an inhibitor cystine knot motif and a selective calcium channel inhibitor. ω-Hexatoxin-Hv1a blocks L-type voltage-dependent Ca 2+ channels and reduces intracellular calcium ion concentration, thereby decreasing apoptosis, necroptosis and oxidative stress, and promoting cell recovery and energy level elevation. ω-Hexatoxin-Hv1a causes larval paralysis and death by impairing neurotransmission in the central nervous system of insects. It shows high injectable toxicity against insects of multiple orders, but exhibits weak oral toxicity. ω-Hexatoxin-Hv1a is widely applicable to studies related to ischemia-reperfusion injury, atopic dermatitis, and ischemic injury of cardiomyocytes and neurons .

    Hm1a

    		Sodium Channel Neurological Disease
    Hm1a is a venom peptide and a selective hNaV1.1 activator with an EC50 of 7.5 nM. Hm1a enhances hNaV1.1 and hNaV1.3 channel currents via delayed inactivation. Hm1a restores action potential firing in Dravet syndrome GABAergic inhibitory interneurons, reduces interictal epileptiform discharges and whole-brain hyperexcitability, lowers seizure frequency, and rescues premature death in Dravet syndrome mice. Hm1a can be used for the research of neurological disease, such as Dravet syndrome .

    Hainantoxin-IV

    HNTX-IV

    		 Sodium Channel Neurological Disease
    Hainantoxin-IV is a specific antagonist of Sodium Channel, targeting to tetrodotoxin-sensitive (TTX-S) voltage-gated sodium channels. His28 and Lys32 are the key resiudes of Hainantoxin-IV for binding with target, while Hainantoxin-IV adopts an inhibitor cystine knot motif .

    ProTx-III

    μ-TRTX-Tp1a

    		 Sodium Channel Neurological Disease
    ProTx-III is a selective and potent inhibitor of voltage-gated sodium channel Nav1.7, with an IC50 of 2.1 nM. ProTx-III is a spider venom peptide isolated from the venom of the Peruvian green velvet tarantella. ProTx-III has a typical inhibitor cystine knot motif (ICK). ProTx-III is able to reverse the pain response. ProTx-III can be used to study diseases such as chronic pain, epilepsy, and arrhythmia .

    ω-Hexatoxin-Hv1a TFA

    ω-ACTX-Hv1 TFA; ω-Atracotoxin-HV1 TFA

    		 Insecticide Apoptosis Calcium Channel Necroptosis Cardiovascular Disease Neurological Disease Inflammation/Immunology
    ω-Hexatoxin-Hv1a (ω-ACTX-Hv1; ω-Atracotoxin-HV1) TFA is an orally active insecticidal neurotoxin containing an inhibitor cystine knot motif and a selective calcium channel inhibitor. ω-Hexatoxin-Hv1a TFA blocks L-type voltage-dependent Ca 2+ channels and reduces intracellular calcium ion concentration, thereby decreasing apoptosis, necroptosis and oxidative stress, and promoting cell recovery and energy level elevation. ω-Hexatoxin-Hv1a TFA causes larval paralysis and death by impairing neurotransmission in the central nervous system of insects. It shows high injectable toxicity against insects of multiple orders, but exhibits weak oral toxicity. ω-Hexatoxin-Hv1a TFA is widely applicable to studies related to ischemia-reperfusion injury, atopic dermatitis, and ischemic injury of cardiomyocytes and neurons .
