The study evaluated the potential of Tacle extracts in inhibiting key enzyme involved in cholesterol biosynthesis, suggesting that the aglycones naringenin and hesperetin may interact with the enzyme catalytic site. Molecular docking simulations indicated similar binding modes and affinities of these compounds to statins, highlighting the nutraceutical potential of Tacle as a dietary supplement for treating moderate hypercholesterolemia.
Tacle(R) is a citrus fruit obtained from the crossbreeding of Clementine and Tarocco cultivars. This fruit retains a promising nutraceutical potential most likely due to a high content in polyphenols, among which the main constituents are the two glycosides naringin and hesperidin. Herein, we evaluated, through an in vitro assay, the capability of Tacle extracts to inhibit the hydroxymethylglutaryl-CoA reductase enzyme, which plays a key role in cholesterol biosynthesis. The results obtained spurred us to investigate whether the anti-enzymatic activity observed may be due to a direct interaction of aglycones naringenin and hesperetin with the enzyme catalytic site. Molecular docking simulations indicated that these two compounds are able to anchor to the protein with binding modes and affinities similar to those found for statins, which represent mainstream medications against hypercholesterolemia. The overall results showed an interesting nutraceutical potential of Tacle, suggesting that its extract could be used for dietary supplementation in the treatment of moderate hypercholesterolemia.
