Sulfur-containing compounds from the roots of Ferula latisecta and their cytotoxic activities

Chemistry, Bioactivity, and Prediction of the Quality Marker (Q-Marker) of Ferula Plants in China: A Review

The genus of Ferula belongs to the family Apiaceae, and many Ferula plants are used as traditional Chinese medicines. Ferula plants were initially identified as early as the "Newly Revised Materia Medica" written in the Tang Dynasty (AD 659), and several of them are also recognized as the traditional medicines of the Uygur, Kazakh, and Mongolian. Ferula plants are distributed in China, Russia, India, Africa, Central Asia, and other places. Currently, the chemical components derived from Ferula plants are mainly coumarins, sesquiterpenes, and volatile oils. Ferula plants can exhibit diverse pharmacological activities such as anti-allergy, analgesia, relieving cough, anticoagulation, and anti-tumor. Therefore, this article summarized the domestic research conducted on the genus Ferula, appropriately combines the research status of the foreign genus Ferula, and describes the chemical composition, biological activity, toxicity issues, and Q-marker prediction. In addition, all the related studies about the genus Ferula are summarized by analyzing the various databases such as CNKI, Wanfang data, PubChem and SciFinder.

Acetylcholinesterase inhibitory activity of Ferula plants and their potential for treatment of Alzheimer's disease

One of the current strategies in the treatment of Alzheimer's disease is using drugs with acetylcholinesterase (AChE) inhibitory property. The existence of various compounds in plants as a potential source for finding new compounds to treat Alzheimer's disease is a scientific fact. Many secondary metabolites and plant extracts have been reported with the ability to inhibit the AChE activity and improve memory and learning. These compounds can increase the concentration of acetylcholine in the brain and improve cholinergic function in individuals with Alzheimer's disease and reduce the symptoms of this neurological disorder. Plants of Ferula genus are a good source of biologically active compounds such as sesquiterpene derivatives, coumarin derivatives and sulfur-containing compounds. Numerous studies on various extracts or purified compounds of Ferula genus have shown that members of this genus have the inhibitory properties on acetylcholinesterase and can also be effective in improving Alzheimer's and amnesia. This review article summarizes studies on plants of Ferula extracts and their derived compounds to find AChE inhibitors.

Ferula communis L. (Apiaceae) Root Acetone-Water Extract: Phytochemical Analysis, Cytotoxicity and In Vitro Evaluation of Estrogenic Properties

Ferula communis L. (F. communis) belongs to the Apiaceae family and is a herbaceous plant with various pharmaceutical properties, due to the different contents of bioactive compounds extracted mainly from its roots, as well as its leaves and rhizome. To date, this plant extract has demonstrated estrogenic, anti-inflammatory, antiproliferative, cytotoxic, antimicrobial and anti-neoplastic properties. Its estrogenic activity is justified by the presence of ferutinin, an ester of a sesquiterpenic alcohol that acts as an agonist for estrogen receptors, with a chemical formula equal to C22H3O4. The component present in F. communis responsible for the toxicity of the plant is ferulenol, a prenylated coumarin with the chemical formula C24H30O3. This compound is capable of inducing mortality via its strong anti-coagulant properties, leading to a lethal hemorrhagic syndrome, ferulosis, in animals that feed on a chemotype of F. communis containing a high amount of ferulenol. The removal of the component ferulenol makes extracts of Ferula non-toxic. In fact, the remaining prenylated coumarins are not present in concentrations sufficient to induce toxicity. The intake of high concentrations of the extract of this plant leads a double dose-dependent effect that is typical of sesquiterpenes such as ferutinin. Here, we assessed the cytotoxicity and the estrogenic properties of the F. communis phytocomplex obtained through extraction using a mixture of acetone and water. Among the active constituents of F. communis, the identification of ferutinin and ferulenol was performed using HPLC. The effects of the extract were evaluated, following the removal of ferulenol, on three cell lines: human breast cancer MCF-7, human cervical cancer HeLa and human osteoblastic sarcoma Saos-2. The choice of these cell lines was justified by the need to mimic certain processes which may occur in vivo and which are estrogen-dependent. The obtained results demonstrated that F. communis extract, in addition to possessing an estrogenic-like property, showed a dose-dependent effect. Low concentrations (0.1–0.8 μM) demonstrated a hyperproliferative effect, whereas higher concentrations (1.6–50 μM) were toxic. Therefore, this extract could be an excellent candidate to make up for a reduction or lack of estrogen.

New Sulfoxide-Containing Derivatives from the Resin of Ferula sinkiangensis

Four undescribed sulfoxide-containing derivatives, sinkiangenoxides A and B, (2Z, 4E)-sinkiangenoxide C, and (2E, 4E)-sinkiangenoxide C (1:  - 4: ), and one known compound, 1-(methylthio)propyl (E)-1-propenyl disulfide (5: ), were isolated from the resin of Ferula sinkiangensis. Their structures were determined based on spectroscopic methods, including IR, UV, HRESIMS, NMR, and CD analysis. Compounds 2:  - 4: showed moderate cytotoxic activities against four human cancer cell lines with IC₅₀ values ranging from 15.0 to 40.3 µM. Sinkiangenoxide B (2: ) was shown to induce apoptosis in HepG2 cells. In addition, compound 5: effectively attenuated lipopolysaccharide-induced nitric oxide release and TNF-α, IL-1β, IL-6, and IL-10 expression.

Water extract of Ferula lehmanni Boiss. prevents high-fat diet-induced overweight and liver injury by modulating the intestinal microbiota in mice

Obesity, often accompanied by hepatic steatosis, has been associated with an increased risk of health complications such as fatty liver disease and certain cancers. Ferula lehmannii Boiss., a food and medicine homologue, has been used for centuries as a seasoning showing anti-bacterial and anti-oxidant effects on digestive discomfort. In the present study, we sought to investigate whether a short-term oral administration of water extract of Ferula lehmanni Boiss. (WEFL) could prevent high-fat diet (HFD)-induced abnormal weight gain and hepatic steatosis in mice and its underlying mechanisms. WEFL reduced HFD-increased body weight, liver injury markers and inflammatory cytokines (i.e. IL-6 and IL-1β), and inhibited the elevation of AMPKα, SREBP-1c and FAS in HFD. Moreover, WEFL reconstructed the gut microbiota composition by increasing the relative abundances of beneficial bacteria, e.g. Akkermansia spp., while decreasing Desulfovibrio spp. and so on, thereby reversing the detrimental effects of HFD in mice. Removal of the gut microbiota with antibiotics partially eliminated the hepatoprotective effects of WEFL. Notably, WEFL substantially promoted the levels of short-chain fatty acids, especially butyric acid. To clarify the functional components at play in WEFL, we used UPLC-MS/MS to comprehensively detect its substance composition and found it to be a collection of polyphenol-rich compounds. Together, our findings demonstrate that WEFL prevented HFD-induced obesity and liver injury through the hepatic-microbiota axis, and such health-promoting value might be explained by the enriched abundant polyphenols.

Pharmacological and Therapeutic Aspects of Plants from the Genus Ferula: A Comprehensive Review

Inspired by nature, humankind has been able to attain significant achievements in the drug and food industries. Particularly, medicinal plants are a rich source of medicinal, cosmetic, sanitary, and aromatic substances. Genus Ferula from the Apiaceae family is a plant genus that possesses over 170 species, which have been carefully documented with regard to their medicinal properties. Ferula spp. affects many body organs, and their respective functions, in humans, such as the immune system, gastrointestinal tract, genitourinary, endocrine, respiratory, cardiovascular, nervous system, bone (skeleton), and teeth. In spite of the benefits, ferulosis (Ferula toxicity) is an important aspect of Ferula consumption in humans and animals. Hemorrhagic problems and infertility are important signs of ferulosis. In this review, we have described all of the effects of the active ingredients of Ferula spp. and their mechanisms of actions, when known, based on an extensive literature review. Thus, our review opens a window of the benefits of Ferula as a phyto-pharmaceutical and its therapeutic applications in pharmacy, dentistry, and medicine.

The volatile oils from the oleo-gum-resins of Ferula assa-foetida and Ferula gummosa: A comprehensive investigation of their insecticidal activity and eco-toxicological effects

Since time immemorial, the oleo-gum-resins of Ferula assa-foetida and F. gummosa are used in the traditional medical systems as well as in foodstuffs, perfumery and cosmetics. In the present study, we explored the insecticidal efficacy of the essential oils obtained from these oleo-gum-resins to widen their fields of industrial applications. The two essential oils were mainly composed of sulfides [sec-butyl (Z)-propenyl disulfide, sec-butyl (E)-propenyl disulfide, sec-butyl (Z)-propenyl trisulfide and sec-butyl (E)-propenyl trisulfide)] and monoterpenes (α-pinene, β-pinene and β-phellandrene), respectively, as determined by GC-MS analysis. The two essential oils were assayed for toxicity on a panel of insects, represented by species of public health relevance (Culex quinquefasciatus and Musca domestica), agricultural (Spodoptera littoralis) and stored-product pests (Prostephanus truncatus and Trogoderma granarium). The ecotoxicological effects of the essential oils were assessed on the aquatic microcrustacean Daphnia magna and the earthworm Eisenia fetida, as well as on human cells. Overall, the two essential oils were effective against important insect pests and vectors. On the other hand, they resulted cytotoxic to fibroblasts and non-target aquatic microcrustaceans. Thus, further insights are needed to determine the full spectrum of their eco-toxicological effects.
