Dynorphin A (1-13) amide is an endogenous opioid peptide that antagonizes morphine-induced analgesia.

This is amino acids 86 to 100 fragment of class II-associated invariant chain peptide called CLIP. The major histocompatibility complex class II molecule displays peptide fragments of foreign proteins to trigger a defensive reaction from the immune system. Before insertion of the foreign peptides into the binding groove, a place-holding peptide CLIP is removed. This is accomplished by the molecule DM, which is shown to increase the dissociation rate of a CLIP peptide from class II.

β-Aminoarteether (SM934 free base), an orally active derivative of Artemisinin, serves a pivotal role in the research of inflammation and autoimmune disorders, including those related to lupus diseases.
