Diphenylterazine is a bioluminescence compound.Diphenylterazine alone yields very little background with excellent signal-to-background ratios. Furthermore, Diphenylterazine elicits minimal cell toxicity at millimolar concentrations. Diphenylterazine injections into untransfected BALB/c mice do not yield any background emission.

Feralolide is a dihydroisocoumarin isolated from the methanolic extract of aloe vera resin. Feralolide is also a dual inhibitor of AChE and BuChE, with IC50s of 55 μg/mL and 52 μg/mL respectively. Feralolide has antioxidant activity and inhibits 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2, 2′-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS). Feralolide could be used in research into cognitive disorders such as Alzheimer's disease, potentially restoring and enhancing memory.
