Hi1a
Hi1a molecule is a peptide from the venom of Australian spider Hadronyche infensa which researchers have found, in studies done on mice, to be an acid-sensing [ion channel] 1a inhibitor. It has cardioprotective properties - preventing heart tissue from degradation during a heart attack and also has a highly neuroprotective effect in case of stroke. It has the potential to become the first drug for acute ischemic events that act by preventing cell death.
