Tyroserleutide TFA, isolated from the degradation products of porcine spleen, is a small molecular tripeptide which inhibits tumor growth both in vitro and in vivo.

Dynorphin A (1-8) is the predominant opioid peptide identified in placental tissue extracts. Dynorphin A (1-8) is the most likely natural ligand of the kappa receptor. The binding of 3H-Bremazocine to the purified kappa receptor is inhibited by Dynorphin A (1-8) (IC50=303 nM).

ABMDMA (9,10-Anthracenediyl-bis(methylene)dimalonic acid) is a chemical probe and indicator with photobleaching properties that can be photobleached by mono-linear oxygen to the corresponding peroxylactone, and can be used to determine photo-induced mono-linear oxygen generation (SOG).
