It was found that chlorotoxin peptides in scorpion Leiurus quinquestriatus venom could delay the activity of human glioma cells in vitro. The venom of Venezuelan scorpion Tityus dispans, which has antibacterial and antiparasitic activity, can inhibit the growth of Leishmania in vitro. The toxin protein Bengalin of Indian scorpion can induce apoptosis of human leukemia cells in vitro and improve the biochemical indexes of osteoporosis in female rats. The \u03b1-neurotoxin found in scorpion venom can delay the inactivation of sodium channel at the neuromuscular junction, and the inactivation of the sodium channel may enhance neuromuscular reflex and airway contraction, which can treat sleep apnea theoretically.<\/p>\n

• Sea anemone toxin peptide drug<\/strong><\/li>\n<\/ul>\n

  Sea anemone is one of the oldest poisonous animals in existence. Like other members of the phylum, sea anemones have many special thorn cells and are widely distributed throughout the body. ShK toxin isolated from anemone is an effective Kv1.3 channel blocker. Kv1.3 channel plays an important role in the activation (proliferation and cytokine production) of human effector memory T cells. ShK can treat T-cell-mediated autoimmune diseases. Such as multiple sclerosis and rheumatoid arthritis. Kv1.3 receptor blockers are also considered to be targets for the treatment of obesity. ShK toxin also has potential applications in the treatment of obesity and insulin resistance. ShK-186, an analog of ShK toxin, now known as Dalazatide, has successfully completed clinical trials and entered the drug market for the treatment of autoimmune diseases.<\/p>\n

  • Leech toxin peptide drug<\/strong><\/li>\n<\/ul>\n

    Leech is an important traditional medicine, which has many functions in the treatment of cerebral hemorrhage and other thrombus-related diseases. Hirudin is an effective anticoagulant in the salivary gland of leeches. Hirudin can inhibit the formation of thrombus and prevent the clotting of host blood. Pharmacological studies have shown that hirudin has the functions of anticoagulation, antithrombus, anti-atherosclerosis, anti-platelet aggregation, anti-tumor, and anti-inflammation, improving hemorheology and protecting the cerebral ischemia-reperfusion injury.<\/p>\n

    Conclusion<\/strong><\/p>\n

    Although a large number of animal toxins have not yet been developed, animal toxin peptide drugs have made great achievements in clinical application, which makes more people realize the great potential and prospect of animal toxin polypeptide drug research and development. However, the effectiveness and safety of many animal toxins in clinical treatment need to be further verified, so the research and development of drugs based on animal toxins is also a great challenge.<\/p>\n
