Phenylpyruvic acid is a substrate for phenylpyruvate decarboxylase and phenylpyruvate tautomerase.

Galanin (1-13)-spantide I is a chimeric peptide composed of the N-terminal fragment of galanin (amino acids 1-13) and spantide, a known substance P receptor antagonist. Galanin (1-13)-spantide I has a high affinity for spinal galanin receptor (Kd=1.16 nM). Galanin (1-13)-spantide I can be used to study the effects of galanin on feeding behavior.
