Galantide, a non-specific galanin receptor antagonist, is a peptide consisting of fragments of galanin and substance P. Galantide recognizes two classes of galanin binding sites (KD<0.1 nM and ~6 nM) in the rat hypothalamus. Galantide dose dependently (IC50=1.0 nM) antagonizes the galanin-mediated inhibition of the glucose-induced insulin secretion from mouse pancreatic islets. Galantide appears to bind to a single population of SP receptors (KD~40 nM).

Defensin HNP-3 human is a cytotoxic antibiotic peptide known as "defensin". Defensin HNP-3 human has inhibitory activity against Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli. Defensin HNP-3 human is initially synthesized as the 94 amino acids preproHNP(1-94), which is hydrolyzed to proHNP(20-94) and converted to mature HNP(65-94) after the removal of anion precursors.
