Secretin (5-27, porcine) (SQ 19301) 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.

Dihydroevocarpine shows potent anti-Helicobacter pylori activity with the minimum inhibitory concentration (MIC) value of 10-20 microg/ml. Dihydroevocarpine is a moderate modulator of p-glycoprotein (p-gp) activity; it shows more potent inhibitory effects against MAO-B compared to MAO-A.

AVE 0991, a nonpeptide analog of angiotensin-(1-7) [Ang-(1-7)], is an orally active Mas agonist with inhibitory effects on [125I]-Ang-(1-7) binding to bovine aortic endothelial cell membranes, and inhibits astrocyte-mediated neuroinflammation in Alzheimer's disease by enhancing autophagy.
