Bisabolene is a sesquiterpene extracted from oregano and other aromatic plants. It is a potential anticancer agent and studies have shown that it can induce apoptosis in the A549 cancer cell line.

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.
