Carotane sesquiterpenes from : analysis as SARS-CoV-2 binding inhibitors.

Two sesquiterpenes, 8α-anisate-dauc-4-ene-3,9-dione (webiol anisate) (1) and 10α-acetoxy-6α-benzoate-jaeschkeanadiol (2) as well as, ten known analogues (3-10), and two sesquiterpene coumarins (11-12) were isolated from an organic root extract of (Fam. Apiaceae). Chemical structures were elucidated based on IR, 1D- and 2D-NMR and HRMS, spectroscopic analyses.

Coss and Durieu: Phytochemical Composition and Biological Activities.

is an Algerian-Tunisian endemic species, which has not been studied yet. Ethyl acetate (EA) and -butanol (Bu) fractions obtained from were investigated for their health benefit properties, in particular with respect to in vivo/in vitro anti-inflammatory and antioxidant activities, as well as their potential to inhibit key enzymes with impact in diabetes (α-glucosidase and α-amylase). The fractions had a distinct phytochemical composition, of which EA was richer in total phenolic compounds (225 mg GAE/g) and mostly composed of the phenylethanoid acetyl martynoside.

Ferulenol, a Sesquiterpene Coumarin, Induce Apoptosis via Mitochondrial Dysregulation in Lung Cancer Induced by Benzo[a]pyrene: Involvement of Bcl2 Protein.

Background: Ferulenol, a sesquiterpene coumarin, was extracted from "Ferula vesceritensis" and possesses pro-oxidative and anticancer effects in different types of cancer.

Objective: The objective of this study is to determine whether ferulenol has an anticancer effect by regulation the Bcl2 protein expression in lung cancer induced by benzo[a]pyrene in Wistar rats.

Methods: Rats in group 1 have received, intraperitoneally, olive oil and considered as controls, animals of group 2 were treated with 100 mg/kg of benzo[a]pyrene intraperitoneally in order to induce lung cancer for 24 weeks, the 3rd groups of rats received the ferulenol 50 mg/kg intraperitoneally after 24 weeks of administration of benzo[a]pyrene and the last group, the rats were treated with ferulenol alone 50 mg/kg.

Ferulenol specifically inhibits succinate ubiquinone reductase at the level of the ubiquinone cycle.

The natural compound ferulenol, a sesquiterpene prenylated coumarin derivative, was purified from Ferula vesceritensis and its mitochondrial effects were studied. Ferulenol caused inhibition of oxidative phoshorylation. At low concentrations, ferulenol inhibited ATP synthesis by inhibition of the adenine nucleotide translocase without limitation of mitochondrial respiration.
