Ferula latisecta gels for synthesis of zinc/silver binary nanoparticles: antibacterial effects against gram-negative and gram-positive bacteria and physicochemical characteristics.

This study explores the potential antibacterial applications of zinc oxide nanoparticles (ZnO NPs) enhanced with silver (Ag) using plant gel (ZnO-AgO NPs). The problem addressed is the increasing prevalence of pathogenic bacteria and the need for new, effective antimicrobial agents. ZnO NPs possess distinctive physicochemical properties that enable them to selectively target bacterial cells. Their small size and high surface area-to-volume ratio allow efficient cellular uptake and interaction with bacterial cells. In this study, the average size of the synthesized ZnO-Ag nanoparticles was 77.1 nm, with a significant standard deviation of 33.7 nm, indicating a wide size distribution. The nanoparticles demonstrated remarkable antibacterial efficacy against gram-negative and gram-positive bacteria, with inhibition zones of 14.33 mm for E. coli and 15.66 mm for B. subtilis at a concentration of 300 µg/ml. Minimum inhibitory concentrations (MIC) were determined to be 100 µg/ml for E. coli and 75 µg/ml for S. saprophyticus. Additionally, ZnO-Ag NPs exhibited excellent biocompatibility, making them appropriate for various pharmacological uses. This study utilizes Ferula latisecta gels, offering a sustainable and eco-friendly approach to nanoparticle synthesis. Incorporating of Ag into ZnO NPs significantly enhances their antimicrobial properties, with the combined results showing great inhibition effects on pathogenic microbes. The findings suggest that ZnO-Ag NPs could be a promising candidate for addressing the challenges posed by drug-resistant bacterial infections and enhancing antimicrobial treatments.

A Comprehensive Review of the Pharmacological Effects of Genus Ferula on Central Nervous System Disorders.

BACKGROUND: Plants of the genus Ferula have long been used to treat neurological diseases such as Alzheimer's disease (AD), pain, depression, and seizures. The main compounds include coumarins, monoterpenes, sulfide compounds, and polyphenol compounds, which can improve the functioning of the nervous system. OBJECTIVE: This article has been compiled with the aim of collecting evidence and articles related to the Ferula effects on central nervous system disease. METHODS: This review article was prepared by searching the terms Ferula and analgesic, anticonvulsant, antidepressant, anti-multiple sclerosis, anti-dementia, and neuroprotective effects.The relevant information was collected through searching electronic databases such as ISI Web of Knowledge, PubMed, and Google Scholar. RESULTS: Genus Ferula has a protective effect on nerve cells by reducing cytokines such as IL-6, IL- 1b, and TNF-α. Therefore, the effects of Ferula plants and their effective ingredients can be used to prevent or improve diseases that destroy the nervous system. The members of this genus play a role in strengthening and improving the antioxidant system, reducing the level of oxidative stress, and inhibiting or reducing inflammatory factors in the nervous system. CONCLUSION: Although the effects of several species of Ferula on the nervous system have been investigated, most studies have not clearly identified the molecular mechanisms as well as the specific functional regions of the brain. The present study was compiled in order to investigate different aspects of the effects of Ferula plants on the central nervous system.

Structure-guided isolation of anti-neuroinflammatory sesquiterpene coumarins from Ferula sinkiangensis.

The resin of Ferula sinkiangensis has been traditionally utilized for treating gastrointestinal disorders, inflammation, tumors, various cancers, and alopecia areata. The primary bioactive constituents, sesquiterpene coumarins, have demonstrated notable therapeutic potential against neuroinflammation. In this study, a structure-guided fractionation method was used to isolate nine novel sesquiterpene coumarins from the resin of F. sinkiangensis. These compounds were characterized and structurally elucidated using comprehensive physicochemical and spectroscopic techniques, including calculated electronic circular dichroism (ECD). Anti-neuroinflammatory assays revealed that compounds 2, 3, and 6 significantly inhibited nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated BV2 microglial cells, with IC50 values ranging from 1.63 to 12.25 µmol·L-1.

Isolation and Characterization of Phenylalanine Ammonia Lyase (PAL) Genes in Ferula pseudalliacea: Insights into the Phenylpropanoid Pathway.

Phenylalanine ammonia lyase (PAL) is a key enzyme regulating the biosynthesis of the compounds of the phenylpropanoid pathway. This study aimed to isolate and characterize PAL genes from Ferula pseudalliacea Rech.f. (Apiales: Apiaceae) to better understand the regulation of metabolite production. Three PAL gene isoforms (FpPAL1-3) were identified and cloned using the 3'-RACE technique and confirmed by sequencing. Bioinformatics analysis revealed important structural features, such as phosphorylation sites, physicochemical properties, and evolutionary relationships. Expression analysis by qPCR demonstrated the differential transcription profiles of each FpPAL isoform across roots, stems, leaves, flowers, and seeds. FpPAL1 showed the highest expression in stems, FpPAL2 in roots and flowers, and FpPAL3 in flowers. The presence of three isoforms of PAL in F. pseudalliacea, along with the diversity of PAL genes and their tissue-specific expression profiles, suggests that complex modes of regulation exist for phenylpropanoid biosynthesis in this important medicinal plant. The predicted interaction network revealed associations with key metabolic pathways, emphasizing the multifaceted roles of these PAL genes. In silico biochemical analyses revealed the hydrophilicity of the FpPAL isozyme; however, further analysis of substrate specificity and enzyme kinetics can clarify the specific role of each FpPAL isozyme. These comprehensive results increase the understanding of PAL genes in F. pseudalliacea, helping to characterize their contributions to secondary metabolite biosynthesis.

Effect of Eucalyptus globulus and Ferula assafoetida essential oils and their nanoformulations on the life table parameters of Tetranychus urticae (Acari: Tetranychidae).

One of the most damaging pests of agricultural crops across the globe is the two-spotted spider mite, Tetranychus urticae Koch. A wide variety of arthropods and plant pathogens can be controlled by essential oils, which are secondary metabolites produced by plants. It is possible to enhance the stability as well as the anti-pest efficiency of plant essential oils by encapsulation. Water distillation was used to extract the essential oils from Eucalyptus globulus and Ferula assafoetida. The chitosan nanoparticles were used to load both essential oils into nanoformulations. Studies were conducted on T. urticae life table characteristics under experimental circumstances to determine the sublethal impacts of essential oils and their nanoformulations. Intrinsic growth rate (r) for population exposed to E. globulus, F. assafoetida essential oils, their nanoformulations and the control were 0.1, 0.069, 0.051, 0.018 and 0.21 per day, respectively. F. assafoetida and E. globulus nanoformulations resulted the lowest fecundity compared to the other treatments. According the result of the lethal and sublethal effects of purified essential oils and nanoformulations of F. assafoetida and E. globulus, they would be recommended for controlling the two-spotted spider mites, T. urticae.

Characteristic terpenylated coumarins from Ferula ferulaeoides as potential inhibitors on overactivation of microglia.

A total of 37 characteristic terpenylated coumarins (1-25), including 17 undescribed compounds (1-5, 6a/6b, 7-10, 11a/11b-13a/13b), have been isolated from the root of Ferula ferulaeoides. Meanwhile, twelve pairs of enantiomers (6a/6b, 11a/11b-15a/15b, 17a/17b, 18a/18b, 20a/20b-22a/22b, and 25a/25b) were chirally purified. The structures of these new compounds were elucidated using HRESIMS, UV, NMR, and calculated 13C NMR with a custom DP4 + analysis. The absolute configurations of all the compounds were determined for the first time using electronic circular dichroism (ECD). Then, their inhibitory effects on nitric oxide (NO) production were evaluated with LPS-induced BV-2 microglia. Compared with the positive control minocycline (IC50 = 59.3 µM), ferulaferone B (2) exhibited stronger inhibitory potency with an IC50 value of 12.4 µM. The immunofluorescence investigation indicated that ferulaferone B (2) could inhibit Iba-1 expression in LPS-stimulated BV-2 microglia.

(17'E) - 9'α, 12'ß - isomarcandin exhibited strong cytotoxicity against HT-29 cell line with IC50 values of 8.94 ± 0.47 µM, and (17'E) - isomarcandin demonstrated strong cytotoxicity against Hela, A549 and HT-29 cell lines with IC50 values of 5.29 ± 0.25, 4.01 ± 0.20, and 4.16 ± 0.21 µM, respectively. This study concluded that, isolated compounds from F. kuhistanica demonstrated strong bioactivity towards anti-vitiligo and cytotoxicity and active compounds are suggested as anti-vitiligo and cytotoxicity agent for future drug development.

A comprehensive review of the molecular and genetic mechanisms underlying gum and resin synthesis in Ferula species.

Ferula spp. are plants that produce oleo-gum-resins (OGRs), which are plant exudates with various colors. These OGRs have various industrial applications in pharmacology, perfumery, and food. The main constituents of these OGRs are terpenoids, a diverse group of organic compounds with different structures and functions. The biosynthesis of OGRs in Ferula spp., particularly galbanum, holds considerable economic and ecological importance. However, the molecular and genetic underpinnings of this biosynthetic pathway remain largely enigmatic. This review provides an overview of the current state of knowledge on the biosynthesis of OGRs in Ferula spp., highlighting the major enzymes, genes, and pathways involved in the synthesis of different terpenoid classes, such as monoterpenes, sesquiterpenes, and triterpenes. It also examines the potential of using omics techniques, such as transcriptomics and metabolomics, and genome editing tools, such as CRISPR/Cas, to increase the yield and quality of Ferula OGRs, as well as to create novel bioactive compounds with enhanced properties. Moreover, this review addresses the current challenges and opportunities of applying gene editing in Ferula spp., and suggests some directions for future research and development.

Cytotoxic and apoptotic effects of Ferula gummosa Boiss: extract on human breast adenocarcinoma cell line.

PURPOSE: Ferula gummosa Boiss. is a well-known and valuable medicinal plant in Iran. Research has shown that this plant has several pharmacological properties, including anti-bacterial, anti-cancer and etc. In the present study, we investigated the cytotoxic properties of F. gummosa Boiss. extract in MCF-7 breast adenocarcinoma cells. METHODS: The cytotoxicity and pro-apoptotic properties of the extract were assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) test and propidium iodide (PI) stained cells, respectively. Apoptosis and necrosis were evaluated by annexin V-PI staining. The levels of reactive oxygen species (ROS),malondialdehyde (MDA), glutathione (GSH), and superoxide dismutase (SOD) was determined to evaluate oxidative stress. The cell migration and the gene expression were assessed by scratch assay and quantitative real-time polymerase chain reaction (q-RT-PCR), respectively. RESULTS: The extract of F. gummosa decreased the viability and cell cycle progression of MCF-7 cells by inducing apoptosis and necrosis, increasing ROS and MDA levels, and decreasing GSH levels and SOD activity. It also lowered the cells' migration capability by enhancing p53 mRNA levels and reducing MMP-9 mRNA expression. CONCLUSION: F. gummosa exhibited pro-apoptotic, anti-proliferative, and anti-metastatic effects on MCF-7 cells. It is therefore recommended that detailed future research be done on different parts of the plant or its secondary metabolites to find anti-cancer lead compounds.

Proteomic and metabolomic insights into seed germination of Ferula assa-foetida.

Cold stratification is known to affect the speed of seed germination; however, its regulation at the molecular level in Ferula assa-foetida remains ambiguous. Here, we used cold stratification (4 °C in the dark) to induce germination in F. assa-foetida and adopted a proteomic and metabolomic approach to understand the molecular mechanism of germination. Compared to the control, we identified 209 non-redundant proteins and 96 metabolites in germinated F. assa-foetida seed. Results highlight the common and unique regulatory mechanisms like signaling cascade, reactivation of energy metabolism, activation of ROS scavenging system, DNA repair, gene expression cascade, cytoskeleton, and cell wall modulation in F. assa-foetida germination. A protein-protein interaction network identifies 18 hub protein species central to the interactome and could be a key player in F. assa-foetida germination. Further, the predominant metabolic pathways like glucosinolate biosynthesis, arginine and proline metabolism, cysteine and methionine metabolism, aminoacyl-tRNA biosynthesis, and carotenoid biosynthesis in germinating seed may indicate the regulation of carbon and nitrogen metabolism is prime essential to maintain the physiology of germinating seedlings. The findings of this study provide a better understanding of cold stratification-induced seed germination, which might be utilized for genetic modification and traditional breeding of Ferula assa-foetida. SIGNIFICANCE: Seed germination is the fundamental checkpoint for plant growth and development, which has ecological significance. Ferula assa-foetida L., commonly known as "asafoetida," is a medicinal and food crop with huge therapeutic potential. To date, our understanding of F. assa-foetida seed germination is rudimentary. Therefore, studying the molecular mechanism that governs dormancy decay and the onset of germination in F. assa-foetida is essential for understanding the basic principle of seed germination, which could offer to improve genetic modification and traditional breeding.

Biological activity of essential oils from Ferulago angulata and Ferula assa-foetida against food-related microorganisms (antimicrobial) and Ephestia kuehniella as a storage pest (insecticidal); an in vitro and in silico study.

Misuse of synthetic pesticides and antimicrobials in agriculture and the food industry has resulted in food contamination, promoting resistant pests and pathogen strains and hazards for humanity and the environment. Therefore, ever-increasing concern about synthetic chemicals has stimulated interest in eco-friendly compounds. Ferulago angulata (Schltdl.) Boiss. and Ferula assa-foetida L., as medicinal species with restricted natural distribution and unknown biological potential, aimed at investigation of their essential oil (EO) biological properties, were subjected. Z-ß-Ocimene and Z-1-Propenyl-sec-butyl disulfide molecules were identified as the major composition of the essential oil of the fruits of F. angulata and F. assa-foetida, respectively. In vitro antimicrobial activity and membrane destruction investigation by scanning electron microscopy imaging illustrated that F. angulata EO had potent antibacterial activity. Besides, the EOs of both plants exhibited significant anti-yeast activity against Candida albicans. In relation to insecticidal activity, both EOs indicated appropriate potential against Ephestia kuehniella; however, the F. assa-foetida EO had more toxicity on the studied pest. Among several insecticidal-related targets, acetylcholinesterase was identified as the main target of EO based on the molecular docking approach. Hence, in line with in vitro results, in silico evaluation determined that F. assa-foetida has a higher potential for inhibiting acetylcholinesterase and, consequently, better insecticide properties. Overall, in addition to the antioxidant properties of both EO, F. angulata EO could serve as an effective prevention against microbial spoilage and foodborne pathogens, and F. assa-foetida EO holds promise as a multi-purpose and natural biocide for yeast contamination and pest management particularly against E. kuehniella.

Comprehensive analysis of different solvent extracts of Ferula communis L. fruit reveals phenolic compounds and their biological properties via in vitro and in silico assays.

Although giant fennel is recognized as a "superfood" rich in phytochemicals with antioxidant activity, research into the antibacterial properties of its fruits has been relatively limited, compared to studies involving the root and aerial parts of the plant. In this study, seven solvents-acetone, methanol, ethanol, ethyl acetate, chloroform, water, and hexane-were used to extract the chemical constituents of the fruit of giant fennel (Ferula communis), a species of flowering plant in the carrot family Apiaceae. Specific attributes of these extracts were investigated using in silico simulations and in vitro bioassays. High-performance liquid chromatography equipped with a diode-array detector (HPLC-DAD) identified 15 compounds in giant fennel extract, with p-coumaric acid, 3-hydroxybenzoic acid, sinapic acid, and syringic acid being dominant. Among the solvents tested, ethanol demonstrated superior antioxidant activity and phenolic and flavonoid contents. F. communis extracts showed advanced inhibition of gram-negative pathogens (Escherichia coli and Proteus mirabilis) and variable antifungal activity against tested strains. Molecular docking simulations assessed the antioxidative, antibacterial, and antifungal properties of F. communis, facilitating innovative therapeutic development through predicted compound-protein interactions. In conclusion, the results validate the ethnomedicinal use and potential of F. communis. This highlights its significance in natural product research and ethnopharmacology.

A histological examination of the effects of Ferula elaeochytris extract on kidney and liver tissues in myoglobinuric acute renal failure.

Myoglobinuric acute renal failure (MARF) is a structural and functional disorder that occurs in the kidney following the release of muscle cell contents into the circulation. In this present study, possible protective and curative effects of Ferula elaeochytris extract against kidney and liver damage in experimentally induced MARF in a rat model were investigated. 3-4 Month-old, 200-250 g Sprague Dawley rats were divided into 8 equal groups with 7 rats per group. Group I was a no-intervention Control group. All groups except for the Group I were dehydrated for 16 hours. Following this dehydration, 50% v/v aqueous glycerol solution was injected into both hind leg muscles of the animals, at a dose of 8 ml/kg. The rats were given physiological saline (SF) once orally before the model was administered (Group II) and after the model was administered (Group V). Similarly, two different doses of Ferula elaeochytris root extract (40 mg/kg and 80 mg/kg) were dissolved in 2 ml of SF and administered orally before (Groups III and IV) and after (Group VI, VII) the model was created. Following the experimental period, kidney and liver tissues were removed from all groups, and fixed in 10% neutral formaldehyde solution for light microscopic examinations. Intracellular vacuolization, enlargement in the Bowman's space, widespread atrophy in the tubular structures, luminal enlargement, and desquamation were detected in the kidney tissue sections of all the experimental model groups. In the liver tissue sections, was detected hepatocyte degeneration, intracellular vacuolization, irregularity in cell membrane borders, and apoptotic bodies. These histopathological consequences of MARF were evaluated for all groups, and whereas a curative effect of Ferula elaeochytris could be seen, its protective effect was higher than its curative effect.

Investigation of physio-mechanical, antioxidant and antimicrobial properties of starch-zinc oxide nanoparticles active films reinforced with Ferula gummosa Boiss essential oil.

The production of surface compounds coated with active substances has gained significant attention in recent years. This study investigated the physical, mechanical, antioxidant, and antimicrobial properties of a composite made of starch and zinc oxide nanoparticles (ZnO NPs) containing various concentrations of Ferula gummosa essential oil (0.5%, 1%, and 1.5%). The addition of ZnO NPs improved the thickness, mechanical and microbial properties, and reduced the water vapor permeability of the starch active film. The addition of F. gummosa essential oil to the starch nanocomposite decreased the water vapor permeability from 6.25 to 5.63 g mm-2 d-1 kPa-1, but this decrease was significant only at the concentration of 1.5% of essential oils (p < 0.05). Adding 1.5% of F. gummosa essential oil to starch nanocomposite led to a decrease in Tensile Strength value, while an increase in Elongation at Break values was observed. The results of the antimicrobial activity of the nanocomposite revealed that the pure starch film did not show any lack of growth zone. The addition of ZnO NPs to the starch matrix resulted in antimicrobial activity on both studied bacteria (Staphylococcus aureus and Escherichia coli). The highest antimicrobial activity was observed in the starch/ZnO NPs film containing 1.5% essential oil with an inhibition zone of 340 mm2 on S. aureus. Antioxidant activity increased significantly with increasing concentration of F. gummosa essential oil (P < 0.05). The film containing 1.5% essential oil had the highest (50.5%) antioxidant activity. Coating also improved the chemical characteristics of fish fillet. In conclusion, the starch nanocomposite containing ZnO NPs and F. gummosa essential oil has the potential to be used in the aquatic packaging industry.

Characterization and investigation of cytotoxicity and antimicrobial properties of coencapsulated limonene and thymol into the Ferula assafoetida gum microparticles.

Thymol (Th) and d-limonene (L) exhibit low stability and are prone to oxidation when exposed to air, light, humidity, and high temperatures. This study examined the coencapsulation of Th and L into Ferula assafoetida gum (AFG) microparticles. Scanning electron microscope (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analyzer (TGA) were done to characterize the obtained complexes. Furthermore, the encapsulation efficiency, antibacterial properties, cytotoxicity, and anticancer properties of both the free and encapsulated forms of L and Th were measured. For all samples, by increasing the percentage of bioactive compound (L, Th, and L-Th) from 2.5 to 5 % w/w, the EE was increased. FTIR and XRD analysis results demonstrated that Th and L were successfully incorporated into the AFG. Additionally, thermogravimetric analysis showed that in the thermal graphs of all samples, the first weight loss occurred between 30 °C and 160 °C, which was due to the evaporation of water. In the free L and Th graph, a sharp reduction peak was observed in which 80 % of compounds were lost. These reduction peaks disappeared in the thermal graphs of L: AFG and Th: AFG revealing that the thermal stability of Th and L was significantly increased upon their incorporation into the AFG. The inclusion of Th into the AFG also led to an increase in its antibacterial activity, while L exhibited acceptable antibacterial activity, albeit not as high as Th. Additionally, according to the MIC results, Th: AFG had the best antibacterial activity among all compounds, especially on gram-positive bacteria. According to the result of the MTT assay, there was a significant difference between the IC50 of free Th (123.4 µg/ml) and Th: AFG (2312 µg/ml), and free L (1762 µg/ml) and L: AFG (2480 µg/ml) showing that encapsulated Th and L into the AFG has decreased the cytotoxicity of free compounds against L929 cell line. Also, Th: AFG had the best anticancer activity against Hella and CT26 cell lines among all compounds. Finally, the flow cytometry analysis demonstrated that the encapsulated particles effectively eliminated cancer cells. The outcomes imply that AFG can be employed as a suitable delivery system to enhance the use of Th and L into the food and pharmaceutical industries.

Dauferulins A-L, daucane-type sesquiterpenes from the roots of Ferula communis: Their structures and biological activities.

Phytochemical study on the roots of a medicinal plant Ferula communis L. (Apiaceae) resulted in the isolation of 20 sesquiterpenes including 12 previously undescribed compounds, dauferulins A-L (1-12). The detailed spectroscopic analysis revealed 1-12 to be daucane-type sesquiterpenes with a p-methoxybenzoyloxy group at C-6. The absolute configurations of 1-12 were deduced by analysis of the ECD spectra. Dauferulins A-L (1-12), known sesquiterpenes (13-20), and analogues (14a-14l) derived from 6-O-p-methoxybenzoyl-10α-angeloyloxy-jeaschkeanadiol (14) were evaluated for their effects on AMPK phosphorylation in human hepatoma HepG2 cells as well as inhibitory activities against erastin-induced ferroptosis on human hepatoma Hep3B cells and IL-1ß production from LPS-treated murine microglial cells.

Efficient extraction of oleoresin from Ferula gummosa roots by natural deep eutectic solvent and its structure and chemical characterizations.

Deep eutectic solvents in the extraction of plant metabolites have found many advantages, such as low toxicity, biodegradability, low cost and ease of preparation over the conventional methods. This work aims to compare natural deep eutectic solvents in extraction and optimization of oleoresin from Ferula gummosa and determining its chemical and structure properties. Box-Behnken design was applied to optimize the extraction of oleoresin from Ferula gummosa using eutectic solvents. The variables of extraction were extraction time, temperature, and ratio of eutectic solvents. Six mixtures of eutectic solvents including choline chloride/urea, acetic acid, lactic acid, formic acid, formamide and glycerol at ratios of 2:1 and 3:1 were evaluated. The highest yields were obtained for choline chloride/formic acid, choline chloride/formamide. The quadratic regression equation was set up as a predictive model with an R2 value of 0.85. The optimum condition was 6 h, 40 °C, and ratio 12.5% (w/v). No significant difference was found between the predicted and experimental yield. The main components of the oleoresin were ß-pinene (40.27%), cylcofenchen (11.93%) and α-pinene (7.53%) as characterized by gas chromatography-mass spectrometry. The chemical structure study by spectroscopy showed that no solvents remained in the oleoresin. Therefore, F. gummosa oleoresin can be explored as a novel promising natural pharmaceutical ingredient extracted with eutectic solvents.

Exploring the anticancer properties of the gum of Ferula gummosa: impact on cytotoxicity, caspase 3/7 activity and apoptosis, and gene expression in SW-480 cells.

Ferula gummosa Boiss. is a well-known Iranian endemic plant that grows in the north and northeast regions of Iran. In Iranian traditional medicine, its gum is utilized to treat inflammation, pain, and infections of the gastrointestinal system. However, no studies have been conducted to investigate the anticancer potential of its gum against colorectal cancer cells. This study aimed to identify the chemical components of the gum of F. gummosa and investigate its effects on SW-480 cells. The experiments included MTT, clonogenic, micronucleus formation, acridine orange/ethidium bromide stain, DNA degradation, caspase 3/7 activity assay, and in vitro wound-healing experiment and investigating the expression of BAX, BCL2, MTOR, and PTEN genes. Chemical analysis using GC/MS identified 102 compounds. The gum had a significant cytotoxic effect on SW-480 cells, with an IC50 value of 1.8 µg/ml for 48 hours. The gum induced apoptosis. Microscopic observations revealed a decrease in cell proliferation, as evidenced by nuclear condensation, increased micronucleus formation, and inhibition of colony formation. Additionally, the gum suppressed cell migration, induced the expression of PTEN and BAX, and down-regulated MTOR and BCL2 genes. These findings suggest that Ferula gummosa has strong cytotoxic properties and warrants further investigation.

Antitumor and Phytochemical Properties of Ferula assa-foetida L. Oleo-Gum-Resin against HT-29 Colorectal Cancer Cells In Vitro and in a Xenograft Mouse Model.

Colorectal cancer (CRC) is one of the most frequently occurring tumors. Ferula assa-foetida oleo-gum-resin (OGR) extract is a traditional cooking spice known for its broad spectrum of biological activities such as antifungal, antiparasitic, and anti-inflammatory activities. This study evaluated the antitumor effect of OGR extract against HT-29 colorectal cancer cells. The OGR chemical composition was analyzed using LC-ESI-MS/MS; MTT, clonogenic assays, and a xenograft model were used to measure cytotoxicity, while apoptotic proteins were detected using Western blotting. Phytochemical analysis revealed that the extract was a rich source of isoflavones, xanthones, and other derivatives. In a dose-dependent manner, the OGR extract significantly inhibited colony formation ability and HT-29 cell growth (IC50 was 3.60 ± 0.02 and 10.5 ± 0.1 mg/mL, respectively). On the other hand, the OGR extract significantly induced apoptosis and increased the expression of some pro-death proteins involved in cellular apoptosis including PUMA, BIM, BIK, and BAK. Moreover, in a subcutaneous HT-29 xenograft model, the tumor volume and burden decreased after treatment with the OGR extract (550 ± 32 mm3 and 16.3 ± 3.6, respectively) This study demonstrated that Ferula assa-foetida OGR ethanolic extract has potential antitumor effects against HT-29 CRC cell lines by reducing cell viability and the function of apoptosis. More studies are needed to reveal the underlying mechanisms related to cytotoxicity and apoptosis induction.
