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.

Ethylmalonic acid can be found in blood cerebrospinal fluid (CSF) and urine as well as in human fibroblasts prostate and skeletal muscle tissues. Moreover ethylmalonic acid is found to be associated with anorexia nervosa and malonyl-CoA decarboxylase deficiency. Ethylmalonic acid is a non-carcinogenic potentially toxic compound.

2-Propen-1-one, 1-(2,6-dimethoxyphenyl)-3-(4-hydroxyphenyl)- can be used in studies about the inhibition against L-phenylalanine ammonia-lyase.
