Acid-sensing ion channels (ASICs) are proton-gated cationic channels involved in pain and other processes, underscoring the potential therapeutic value of specific inhibitors such as the three-finger toxin mambalgin-1 (Mamb-1) from snake venom. A low-resolution structure of the human-ASIC1a/Mamb-1 complex obtained by cryo-electron microscopy...

Huwentoxin-IV (HwTx-IV), a peptide discovered in the venom of the Chinese bird spider Cyriopagopus schmidti, has been reported to be a potent antinociceptive compound due to its action on the genetically validated NaV1.7 pain target. Using this peptide for antinociceptive applications in vivo suffers from one major drawback, namely its negative...

Mambalgins are 57-amino acid peptides isolated from mamba venom. They produce potent analgesic effects in mice against inflammatory pain upon central intrathecal (i.t.), and peripheral local (i.pl.) injections, through inhibition of different ASICs subtypes and involvement of opioid-independent pathways. They produce fewer side effects than...
