Antho-RFamide is a neuropeptide isolated from the sea anemone (Anthopleura elegantissima). Antho-RFamide contains a specific carboxyl-terminal sequence, Arg-Phe-NH2, that plays an important role in neural signaling. Antho-RFamide can be used to study the function of neuropeptides in the nervous system of the simplest animals.

Sarafotoxin S6b is a vasoconstrictor peptide, and a non-selective endothelin receptor agonist. Sarafotoxin S6b can induce contraction in isolated human coronary arteries , the Ki values of Coronary artery, Saphenous vein and Coronary artery are 0.27, 0.55 and 19.5 nM, respectively.

[Lys3]-Bombesin is a biological active peptide. (PET (Positron Emission Tomography) imaging of [Lys3]-bombesin is able to detect gastrin-releasing peptide receptor (GRPR) positive prostate cancer. An immunoconjugate of [Lys3]-bombesin and corresponding monoclonal antibody can specifically induce (CD64)-dependent monocyte and neutrophil-mediated lysis of small cell carcinoma.)
