AS057278 is an D-amino acid oxidase (DAAO) inhibitor.

Ranatensin is a undecapeptide and a Bombesin Receptor angonist, can be isolated from amphibian skin, such as the frog, Rana pipiens. Ranatensin could maintain the dynamic balance of animal blood pressure, without cross-tachyphylaxis with Angiotensin amide, Bradykinin , or Norepinephrine .

Neuromedin U-8 (porcine) is a polypeptide that can be found by peptide screening. Peptide screening is a research tool that pools active peptides primarily by immunoassay. Peptide screening can be used for protein interaction, functional analysis, epitope screening, especially in the field of agent research and development.
