Juglandaceae

beta-Amyrone (β-Amyron) has antifungal activity against Chikungunya virus replication with an EC50 of 86 uM. beta-Amyrone has anti-inflammatory activity through inhibiting the expression of COX-2. beta-Amyrone exhibits anti-α-glucosidase inhibitory activity and moderate AChE activity. β-Amyrone can be used in the research of disease like inflammation, infection, and obesity.

1. Engeletin (Dihydrokaempferol 3-rhamnoside) may serve as a potential anti-inflammatory agent. 2. Engeletin possesses potent inhibition of PGE2 release with IC5 values of 19.6 μg/ml. 3. Engeletin inhibits a recombinant human aldose reductase (IC5 value=1.16 microM).

Juglone (Regianin) is a natural naphthoquinone found in the black walnut (J. nigra) and other plants in the Juglandaceae family. Juglone also irreversibly inhibits peptidyl-prolyl cis/trans isomerases of the parvulin family, including human Pin1, yeast Ess1/Ptf1, and E. coli parvulin (Ki = 55.9 nM). Juglone also blocks transcription by RNA polymerases I, II, and III (IC50s = 2-7 μM) and attenuates kidney fibrosis in rats treated with unilateral ureteral obstruction, both through Pin1-independent mechanisms.

Regiolone is a naphthoquinone natural product with phytotoxic properties. In in vitro studies, Regiolone exhibits antiproliferative activity in tumor cells and can induce apoptosis in MCF-7 breast cancer cells.

28-Demethyl-beta-amyrone is a natural product
