• Biologische Aktivität

  huwentoxin xvi(hwtx-xvi ) is composed of 39 amino acid residues including six cysteines. hwtx-xvi is a novel neurotoxin from the venom of chinese tarantula o. huwena. and specificially block n-type calcium channels. [1]n-type calcium channels are often highly expressed both in dorsal root ganglia cell bodies and in the synaptic terminals projecting to dorsal horn of the spinal cord n-type calcium channels play important roles in the control of neurotransmission release and transmission of pain signals to the central nervous system.[2]electrophysiological assay indicated that hwtx-xvi specifically inhibited n-type calcium channels in rat dorsal root ganglion cells. hwtx-xvi specifically inhibits gvia sensitive, n-type calcium channels in rat drg cells.[1]hwtx-xvi could almost completely block the twitch response of rat vas deferens to low-frequency electrical stimulation. hwtx-xvi ‘s analgesic effects, non-toxic and complete reversibility make it an interesting tool for developing novel drugs for the treatment of n-type calcium channel-related diseases.[1,2]
