Imperatorin attenuates CCl 4-induced cirrhosis and portal hypertension by improving vascular remodeling and profibrogenic pathways. Eur J Pharmacol 2024; 980:176833. [PMID: 39089464 DOI: 10.1016/j.ejphar.2024.176833] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2024] [Revised: 06/28/2024] [Accepted: 07/18/2024] [Indexed: 08/04/2024]
Abstract
BACKGROUND Cirrhosis leads to portal hypertension (PHT), affecting survival with limited treatment options. This study investigated Imperatorin (IMP), a furanocoumarin with anti-inflammatory and hypotensive properties, for its therapeutic role and mechanisms in cirrhotic PHT. METHODS Hepatic stellate cells (HSCs) inhibition by IMP was evaluated using LX-2 cell line. Rat cirrhosis was induced via CCl4 for 16 weeks. Experimental group were orally administered IMP (15/25 mg/kg/day) for 4 weeks. We subsequently examined portal pressure (PP), cirrhosis, inflammation, angiogenesis, and vascular remodeling. Network pharmacology was employed for mechanistic insights. RESULTS IMP significantly inhibited the fibrogenesis in HSCs and suppressed cell viability. CCl4 exposure induced cirrhosis, inflammation, angiogenesis, vascular remodeling and PHT. IMP significantly reduced PP from 22.85 ± 3.88 mmHg to 6.67 ± 0.6 mmHg, diminished collagen deposition and pro-fibrotic factor expression, alleviated inflammation, and improved liver function. Vessel wall thickness in superior mesenteric arteries was restored, and intra-/extrahepatic angiogenesis was inhibited via VEGF and vWF. Furthermore, IMP induced sinusoidal vasodilation by upregulating eNOS and GCH1. Enrichment analysis indicated that IMP was involved in various biological processes associated with cirrhosis, such as the regulation of blood pressure, tissue remodeling, response to inflammation, and regulation of angiogenesis, etc. Additionally, IMP suppressed hepatic expression of TGF-β both in vitro and in vivo, which was further supported by KEGG analysis. CONCLUSION Our research demonstrated that IMP significantly mitigated cirrhosis PHT by reducing hepatic fibrosis and inflammation, curbing angiogenesis and vascular remodeling, and promoting vasodilation. This protective mechanism appears to be facilitated through the downregulation of TGF-β.

Pharmaceuticals (Basel) 2023; 16:1595. [PMID: 38004460 PMCID: PMC10674403 DOI: 10.3390/ph16111595] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Revised: 11/03/2023] [Accepted: 11/10/2023] [Indexed: 11/26/2023] Open
Abstract
The high expression of the ATP-binding cassette (ABC) drug transporter ABCG2 in cancer cells contributes to the emergence of multidrug resistance (MDR) in individuals afflicted with either solid tumors or blood cancers. MDR poses a major impediment in the realm of clinical cancer chemotherapy. Recently, substantial endeavors have been dedicated to identifying bioactive compounds isolated from nature capable of counteracting ABCG2-mediated MDR in cancer cells. Imperatorin, a natural coumarin derivative renowned for its diverse pharmacological properties, has not previously been explored for its impact on cancer drug resistance. This study investigates the chemosensitizing potential of imperatorin in ABCG2-overexpressing cancer cells. Experimental results reveal that at sub-toxic concentrations, imperatorin significantly antagonizes the activity of ABCG2 and reverses ABCG2-mediated MDR in a concentration-dependent manner. Furthermore, biochemical data and in silico analysis of imperatorin docking to the inward-open conformation of human ABCG2 indicate that imperatorin directly interacts with multiple residues situated within the transmembrane substrate-binding pocket of ABCG2. Taken together, these results furnish substantiation that imperatorin holds promise for further evaluation as a potent inhibitor of ABCG2, warranting exploration in combination drug therapy to enhance the effectiveness of therapeutic agents for patients afflicted with tumors that exhibit high levels of ABCG2.

Abstract
Humans are unique indiscriminate carotenoid accumulators, so the human body accumulates a wide range of dietary carotenoids of different types and to varying concentrations. Carotenoids were once recognized as physiological antioxidants because of their ability to quench singlet molecular oxygen (1O2). In the 1990s, large-scale intervention studies failed to demonstrate that supplementary β-carotene intake reduces the incidence of lung cancer, although its antioxidant activity was supposed to contribute to the prevention of oxidative stress-induced carcinogenesis. Nevertheless, the antioxidant activity of carotenoids has attracted renewed attention as the pathophysiological role of 1O2 has emerged, and as the ability of dietary carotenoids to induce antioxidant enzymes has been revealed. This review focuses on six major carotenoids from fruit and vegetables and revisits their physiological functions as biological antioxidants from the standpoint of health promotion and disease prevention. β-Carotene 9',10'-oxygenase-derived oxidative metabolites trigger increases in the activities of antioxidant enzymes. Lutein and zeaxanthin selectively accumulate in human macular cells to protect against light-induced macular impairment by acting as antioxidants. Lycopene accumulates exclusively and to high concentrations in the testis, where its antioxidant activity may help to eliminate oxidative damage. Dietary carotenoids appear to exert their antioxidant activity in photo-irradiated skin after their persistent deposition in the skin. An acceptable level of dietary carotenoids for disease prevention should be established because they can have deleterious effects as prooxidants if they accumulate to excess levels. Finally, it is expected that the reason why humans are indiscriminate carotenoid accumulators will be understood soon.

Abstract
Two recent trends that have developed simultaneously are a mistrust of health products by some of the population and the growing popularity of essential oils. The objective of this study was to analyze recipes with essential oils found on the internet and to assess their level of photoprotective efficacy. Therefore, we conducted a study of 140 recipes for personal care and hygiene products that incorporate one or more essential oils. This analysis revealed that numerous essential oils are called for in these recipes, derived from plants belonging to a wide diversity of botanical families. There was a significant difference (p=0.0026) in the number of essential oils listed in the recipes for facial care and body care recipes. There was also a statistically significant difference (p=2.54E-5) in the amount of essential oil to be added, expressed in drops, according to the type of product being made. A common characteristic of most of the recipes was the absence of any antimicrobial agents or antioxidants, which poses serious issues of preservation for the finished products. Recipes with essential oils pose many issues. The first issue lies in the quantities of the different raw materials to be incorporated; it influences the final essential oil concentration. The second issue concerns the adverse effects (photosensitization, for example) and contraindications (pregnant women, nursing women) of certain essential oils. Finally, it is not possible to carry out physicochemical testing raw materials and finish preparation.

Abstract
Microbial resistance is an important problem in modern healthcare systems. In addition to drug resistance, the side effects of current antibiotic applications are also known issues. In this present study, binary combinations of amoxicillin with European Pharmacopoeia quality lavender (Lavandula angustifolia) and fennel (Foeniculum vulgare) essential oils were evaluated against human pathogenic microbial strains. The checkerboard method was used to quantify the efficacy of the essential oils in combination with amoxicillin. As an initial result, remarkable in vitro antimicrobial activity was observed at relatively low amoxicillin concentrations using different oil combinations against Staphylococcus aureus ATCC 6538, Enterococcus faecalis ATCC 29212, Bacillus cereus ATCC 14579, Escherichia coli NRRL B-3008, Salmonella typhi (clinical isolate), respectively. Fractional inhibitory concentrations were calculated and interpreted in terms of addition, synergy, antagonism, or indifferent. A synergistic interaction with the combination F. vulgare essential oil and amoxicillin (fractional inhibitory concentration index = 8.05 × 10-4) was observed against the pathogens E. faecalis and Escherichia coli. Both essential oils together and in combination with amoxicillin showed a synergistic effect with possible future applications.

Abstract
Background: Polycystic ovary syndrome (PCOS) is a complex endocrine disorder associated with irregular menstrual cycles, hyperandrogenism, obesity, and reduced fertility. Objectives: The present study aimed to formulate herbal syrup based on Iranian traditional medicine (ITM) and evaluate its effect on the letrozole-induced PCOS model in female rats. Methods: The herbal syrup contains anise, fennel, and celery seed extracts. Five different formulations were made with different percentages of additive components. Quality control and stability tests were performed on the selected formulation. During the in vivo step, 6 groups of rats were evaluated: The control group (received carboxymethyl cellulose 1% as a vehicle) and the other 5 groups (received letrozole 1 mg/kg orally for 21 days). During 21 days, daily vaginal smears were examined to detect irregularities of the estrous cycle. After induction of PCOS, rats were orally administered with herbal syrup (1, 2, 4 mL/kg) or metformin (200 mg/kg) for 28 days. Moreover, body and ovarian weights, serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, progesterone, and testosterone were measured. Finally, ovarian tissues were isolated for histological examination. Results: The best formulation of the syrup contained the plant extract (totally 10%), sugar (50%), sodium benzoate (0.1%), and potassium sorbate (0.1%). Body weight was significantly increased in all groups compared to the control group, and after treatment, a significant weight reduction was seen in the metformin and 1-mL/kg dose group. Following PCOS induction, ovary weight was significantly increased, while after treatment, it showed a significant decrease. After 21 days of letrozole administration, induction of PCOS was confirmed by the irregularities in estrous cycles and an increase in testosterone and LH levels. After treatments with the syrup, LH levels significantly decreased in all groups (P < 0.05), and serum testosterone and FSH levels significantly decreased in the 2-mL/kg dose group compared to the PCOS group (P < 0.05). Estradiol and progesterone levels significantly increased in the treatment groups in a dose-dependent manner. Histological studies of metformin and herbal syrup groups exhibited normal follicular development with fewer and smaller cystic follicles compared to the PCOS group. Conclusions: The herbal syrup made from anise, fennel, and celery seed extracts improved serum levels of sex hormones, recovered the ovarian morphology in PCOS-induced rats, and can be a good candidate for further clinical trials.

Abstract
Sosnovsky's hogweed, Heracleum sosnowskyi has a high photosensitizing ability. Although Sosnovsky's hogweed is known as a poisonous plant, its chemical composition and phototoxicity are poorly studied. We analyzed the chemical composition of the Sosnovsky's hogweed juice that grew in natural conditions. It was found that the content of 8-methoxypsoralen in the juice is 1332.7 mg/L, and that of 5-methoxypsoralen is 34.2 mg/L. We have developed and analyzed liposomes containing furanocoumarins of Sosnovsky's hogweed juice and studied their photocytotoxicity in L929 mouse fibroblast cell culture. It was found that liposomes containing furanocoumarins of Sosnovsky's hogweed juice are more toxic for L929 cells in comparison with liposomal forms of pure substances 8-methoxypsoralen and 5-methoxypsoralen. It was found that when exposed to UV radiation at 365 nm at a dose of 22.2 J/cm2, the liposomal form of furanocoumarins Sosnovsky's hogweed is 3 times more toxic to L929 cells than in the dark. It was found that the photocytotoxic effect of liposomal furanocoumarins Sosnovsky's hogweed is a strongly stimulation of apoptosis.The data obtained suggest that the raw material of Sosnovsky's hogweed claims to be a source of furanocoumarins, and the liposomal form, given the hydrophobic properties of furanocoumarins, is very suitable for creating a phototherapeutic drug.

Abstract
The factors behind the pathogenesis of lung cancer are not clear, and treatment failure is generally caused by drug resistance, recurrence, and metastasis. Development of new therapeutic agents to overcome drug-resistance remains a challenge clinically. Various extracts of Foeniculum vulgare have shown promising anticancer activity; however, effects on lung cancer and the underlying molecular mechanisms of action are not clear. In the present study, we found that the ethanol extract of Foeniculum vulgare seeds (EEFS) significantly reduced lung cancer cell growth in vitro and in vivo. EEFS decreased the viability of and triggered apoptosis in the lung cancer cell lines NCI-H446 and NCI-H661. EEFS induced apoptosis mainly through inhibition of Bcl-2 protein expression, reduction of mitochondrial membrane potential, and release of Cytochrome C. Moreover, EEFS significantly inhibited colony formation and cell migration in lung cancer cells. EEFS also effectively inhibited the growth of xenograft tumors derived from NCI-446 cells by reducing Bcl-2 protein expression and inducing apoptosis. Taken together, these findings suggest that EEFS exerts anti-lung cancer activity by targeting the Bcl-2 protein and may have potential as a therapeutic drug for lung cancer.

Abstract
As a naturally occurring furanocoumarin, the medicinal value of imperatorin has been studied more and more. We hope to provide useful information for the further development of imperatorin by analyzing the literature of imperatorin in recent years. By collating the literature on the pharmacology of imperatorin, we found that the pharmacological activity of imperatorin is wide and imperatorin can be used for anti-cancer, neuroprotection, anti-inflammatory, anti-hypertension and antibacterial. In addition, we found that some researchers confirmed the toxicity of imperatorin. Pharmacokinetic studies demonstrated that oxidation metabolism is the main metabolic pathways of imperatorin. At present, the shortcomings of research on imperatorin mainly include: most pharmacological studies are concentrated in vitro, lacking enough in vivo experimental data; more and more studies showed that imperatorin has synergistic effect with other drugs in anticancer and other aspects, but lacking the detailed explanation of the mechanism of the synergistic effect; imperatorin has side effect, but it lacks enough experimental conclusions. Based on the above defects, we believe that more in vivo experiments of imperatorin should be carried out in the future; future research need to explore synergistic mechanisms of imperatorin with other drugs, especially in anticancer; the dose affects both the pharmacological activity and the side effect of imperatorin. The relationship between the dose and the two aspects need to be further studied in order to reduce the side effect. In addition, through structural modification of imperatorin, it is possible to improve the treatment effect and reduce side effect.
