α-Conotoxin PnIA is a peptide originally isolated from the venom of the marine mollusk C. pennaceus and an antagonist of α3β2 subunit-containing nicotinic acetylcholine receptors (nAChRs) and α7 nAChRs (IC50s = 7.9 and 62.7 nM, respectively).1,2 α-Conotoxin PnIA (0.1 nmol/kg) in combination with baicalein inhibits tumor growth and increases survival in an Ehrlich murine spontaneous adenocarcinoma model.3
