Bradykinin potentiator C is a potent angiotensin-converting enzyme (ACE) inhibitor with an IC50 of 7.1 μM for rabbit lung ACE. Bradykinin potentiator C is a postulated prototype of functional peptide.

Pogostone possesses potent anti-bacterial and anti-fungal activities, such as gram negative bacteria , gram positive bacteria, Escherichia coli.

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.
