Head activator neuropeptide is a mitogen for mammalian cell lines of neuronal or neuroendocrine origin. Head activator neuropeptide signals by binding GPR37 and stimulates cells to enter mitosis.

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.

N-Acetyldopamine dimer-1 is a 2-(3',4'-dihydroxyphenyl)-1,4-benzodioxane derivative. N-Acetyldopamine dimer-1 is optically active, can be isolated from crude agent "Zentai," a cast-off shell of the cicada of Cryptotympana sp. (Cicadidae).
