pTH (1-34) amide (human) 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.

Nortrachelogenin ((-)-Wikstromol), which can be extracted from Partrinia scabiosaefolia, has antifungal activity and induces membrane disruption and cysteinyl asparagin-dependent apoptosis.
