Bruceine A alleviates alcoholic liver disease by inhibiting AIM2 inflammasome activation via activating FXR

BackgroundAlcoholic liver disease (ALD), a public health challenge worldwide caused by long-term persistent drinking, is life-threatening with minimal approved therapies. Hepatic steatosis accompanied by inflammation is an initial and inevitable stage in the complex progression of simple alcoholic liver injury to more severe liver diseases such as hepatitis, liver fibrosis, cirrhosis and liver cancer. PurposeWe aimed to identify the therapeutic role of Bruceine A (BA) in ALD whilst attempting to explore whether its protective effects depend specifically on the farnesoid X receptor (FXR). MethodsAutodock was applied to detect the affinity between BA and FXR. Lieber-DeCarli liquid diet with 5 % ethanol (v/v) was adopted to establish the mouse ALD model. The lentivirus mediating FXR (LV-FXR) was injected into mice via the tail vein to establish FXR-overexpressed mice. FXR silencing or overexpression plasmids were transfected into AML-12 cells prior to ethanol stimulation. Quantitative real-time PCR, Western blotting and immunofluorescence assays were employed to determine the expression of related genes. We subjected liver sections to H&E and Oil Red O staining to evaluate the liver histological injury and the deposition of lipid droplets. ResultsBA significantly reduced body weight and liver-to-body weight ratios as well as biochemical indexes in mice. Ethanol-induced liver damage and lipid accumulation could be alleviated by BA treatment. BA bound to FXR by two hydrogen bonds. There was a positive correlation between BA administration and FXR expression. BA inhibited the expression of lipid synthesis genes and enhanced the expression of lipid metabolism genes by activating FXR, thus alleviating steatosis in ALD. Moreover, BA exerted an ameliorative effect against inflammation by inhibiting the activation of absent in melanoma 2 (AIM2) inflammasome by activating FXR. FXR overexpression possessed the ability to counter the accumulation of lipid and the activation of AIM2 inflammasome caused by ethanol. FXR deficiency exacerbated ethanol-induced liver steatosis and inflammation. The hepatoprotective effect of BA could be disrupted by FXR antagonist guggulsterone (GS) in vivo and FXR siRNA in vitro. ConclusionBA alleviated alcoholic liver disease by inhibiting AIM2 inflammasome activation through an FXR-dependent mechanism. This study may potentially represent a new therapeutic approach for ALD.

Guggulsterone Selectively Modulates STAT-3, mTOR, and PPAR-Gamma Signaling in a Methylmercury-Exposed Experimental Neurotoxicity: Evidence from CSF, Blood Plasma, and Brain Samples.

Amyotrophic lateral sclerosis (ALS) is a paralytic disease that damages the brain and spinal cord motor neurons. Several clinical and preclinical studies have found that methylmercury (MeHg+) causes ALS. In ALS, MeHg+-induced neurotoxicity manifests as oligodendrocyte destruction; myelin basic protein (MBP) deficiency leads to axonal death. ALS development has been connected to an increase in signal transducer and activator of transcription-3 (STAT-3), a mammalian target of rapamycin (mTOR), and a decrease in peroxisome proliferator-activated receptor (PPAR)-gamma. Guggulsterone (GST), a plant-derived chemical produced from Commiphorawhighitii resin, has been found to protect against ALS by modulating these signaling pathways. Vitamin D3 (VitD3) deficiency has been related to oligodendrocyte precursor cells (OPC) damage, demyelination, and white matter deterioration, which results in motor neuron death. As a result, the primary goal of this work was to investigate the therapeutic potential of GST by altering STAT-3, mTOR, and PPAR-gamma levels in a MeHg+-exposed experimental model of ALS in adult rats. The GST30 and 60mg/kg oral treatments significantly improved the behavioral, motor, and cognitive dysfunctions and increased remyelination, as proven by the Luxol Fast Blue stain (LFB), and reduced neuroinflammation as measured by histological examinations. Furthermore, the co-administration of VitD3 exhibits moderate efficacy when administered in combination with GST60. Our results show that GST protects neurons by decreasing STAT-3 and mTOR levels while increasing PPAR-gamma protein levels in ALS rats.

Current stage of preclinical and clinical development of guggulsterone in cancers: Challenges and promises.

Throughout human history, the utilization of medicinal herbs has been recognized as a crucial defense against various ailments, including cancer. Natural products with potential anticancer properties, capable of inducing apoptosis in cancer cells, have garnered substantial attention. One such agent under investigation is guggulsterone (GS), a phytosterol derived from the gum resin of the Commiphora mukul tree. This review aims to provide a comprehensive summary of recent studies elucidating the anticancer molecular mechanisms and molecular targets of GS, guiding future research and potential applications as an adjuvant drug in cancer therapy. Recent in vivo and in vitro studies have explored the biological activities of the active ingredients in Commiphora mukul. Specifically, GS emerges as a potential cancer chemopreventive and therapeutic agent. The investigations delve into the impact of GS on constitutively activated survival pathways, including Janus kinase/signal transducer and activator of transcription (JAK/STAT), nuclear factor-kappa B (NF-kB), and PI3-kinase/AKT signaling pathways. These pathways regulate antiapoptotic and proinflammatory genes, exerting control over growth and inflammatory responses. The findings highlight the potential of GS in disrupting survival pathways crucial for cancer cell viability. The inhibition of JAK/STAT, NF-kB, and PI3-kinase/AKT signaling pathways positions GS as a promising candidate for cancer therapy. The review synthesizes evidence from diverse studies, underscoring the multifaceted biological activities of GS in cancer prevention and treatment. To advance our understanding, future clinical and translational studies are imperative to determine effective doses in humans. Additionally, there is a need for the development of new pharmaceutical forms of GS to optimize therapeutic effects. This comprehensive review provides a foundation for ongoing research, offering insights into the potential of GS as a valuable addition to the armamentarium against cancer.

Guggulsterone Promotes Nasopharyngeal Carcinoma Cells Exosomal Circfip1L1 to Mediate miR-125a-5p/VEGFA Affecting Tumor Angiogenesis.

Nasopharyngeal carcinoma (NPC) is a usual head and neck malignancy. Guggulsterone (GS) has potential in cancer chemoprophylaxis and treatment, but its therapeutic effect on NPC is unknown. We aimed to explore whether GS could promote the secretion of exosomal circFIP1L1 from NPC cells and its regulatory mechanism. NPC tissues and adjacent tissues were collected from NPC patients. Human nasopharyngeal epithelial cell lines (NP69) and NPC lines (5-8F, CNE1, and HNE1) were used for in vitro experiments. HNE1 cells were treated with GS (20, 40, 60 μmol/L). The expressions of miR-125a-5p and circFIP1L1 were evaluated by qRT-PCR. Cell proliferation and apoptosis abilities were measured by CCK-8 and flow cytometry. HNE1 cell exosomes were extracted and identified, and the levels of VEGFA and VEGFR2 were detected by ELISA. Then miR-125a-5p was knocked down and overexpressed. HUVECs angiogenesis was determined by the tube formation assay. qRT-PCR and Western blot were utilized to evaluate the expressions of VEGFA, MMP-2, MMP-9, and ICAM-1 in HUVECs. miR-125a-5p was highly expressed in NPC tissues and cells. GS promoted the secretion of exosomal circFIP1L1 from HNE1 cells to affect HUVECs proliferation and angiogenesis. Overexpression of miR-125a-5p accelerated HUVECs proliferation and angiogenesis. Knocking down miR-125a- 5p inhibited VEGFA expression. In addition, exosomal circFIP1L1 sponged miR-125a-5p, inhibiting the VEGFA pathway to repress HUVECs angiogenesis. GS promoted exosomal circFIP1L1 in NPC cells to mediate miR-125a-5p/VEGFA axis affecting tumor angiogenesis.

Guggulsterone protects against lipopolysaccharide-induced inflammation and lethal endotoxemia via heme oxygenase-1

Guggulsterone (GS) is a phytosterol used to treat inflammatory diseases. Although many studies have examined the anti-inflammatory activities of GS, the detailed mechanisms of GS in lipopolysaccharide (LPS)-induced inflammation and endotoxemia have not yet been examined. Therefore, we investigated the anti-inflammatory effects of GS on LPS-induced inflammation. In murine peritoneal macrophages, the anti-inflammatory activity of GS was primarily mediated by heme oxygenase-1 (HO-1) induction. HO-1 induction by GS was mediated by GSH depletion and reactive oxygen species (ROS) production. The ROS generated by GS caused the phosphorylation of GSK3β (ser9/21) and p38, leading to the translocation of nuclear factor erythroid-related factor 2 (Nrf2), which ultimately induced HO-1. In addition, GS pretreatment significantly inhibited inducible nitric oxide synthase (iNOS), iNOS-derived NO, and COX-2 protein and mRNA expression, and production of COX-derived prostaglandin PGE2, interleukin (IL)-1β, IL-6, and tumor necrosis factor-α (TNF-α). In a mouse model of endotoxemia, GS treatment prolonged survival and inhibited the expression of inflammatory mediators, including IL-1β, IL-6, and TNF-α. GS treatment also inhibited LPS-induced liver injury. These results suggest that GS-induced HO-1 could exert anti-inflammatory effects via ROS-dependent GSK (ser21/9)-p38 phosphorylation and nuclear translocation of Nrf2.

Farnesoid X receptor activation is required for the anti-inflammatory and anti-oxidative stress effects of Alisol B 23-acetate in carbon tetrachloride-induced liver fibrosis in mice

Previous studies have shown that Alisol B 23-acetate (23ABA) had potent liver-protection effects, however, its roles and potential mechanisms in carbon tetrachloride (CCl4)-induced liver fibrosis remain to be determined. The present study aimed to investigate the effects of 23ABA on CCl4-induced liver fibrosis and tried to elucidate the underlying mechanisms by focusing on regulating of farnesoid X receptor (FXR). In vivo study found that 23ABA alleviated the CCl4-induced liver injury, and showed no obvious systemic toxicity on mice. 23ABA inhibited the collagen production, decreased sera levels of hyaluronic acid (HA) and procollagen type III (PC-III), lowered mRNA expression of α-smooth muscle actin (α-SMA), fibronectin, collagen I and collagen III in livers of mice. 23ABA inhibited the mRNA expressions and the sera levels of interleukin-6 (IL-6), IL-1β, and tumor necrosis factor-α (TNF-α), as well as decreased the expression of cyclooxygenase 2 (COX-2) in fibrotic livers of mice. Besides, 23ABA decreased levels of reactive oxygen species (ROS) and malondialdehyde (MDA), increased glutathione (GSH) level, enhanced activities of superoxide dismutase (SOD) and glutathione reductase (GR) as well as increased mRNA expression of nuclear factor-E2-related factor 2 (Nrf2), glutamate-cysteine ligase, catalytic subunit (GCLC) and glutamate-cysteine ligase, modifier subunit (GCLM). Further study showed that the anti-liver injury and anti-fibrotic effects of 23ABA were abrogated by FXR antagonist guggulsterone (GS) in vivo. In addition, the inhibition effects of 23ABA on liver inflammation and oxidative stress were also weakened by treatment with GS in CCl4-induced fibrotic mice livers. In conclusion, the protective effects of 23ABA against CCl4-induced liver injury and fibrosis, due to FXR-mediated regulation of liver inflammation and oxidative stress.

Guggulsterone inhibits migration and invasion through proteasomal and lysosomal degradation in human glioblastoma cells

Glioblastoma multiforme (GBM) is a deadly brain malignancy, and current therapies offer limited survival benefit. The phytosterol guggulsterone (GS) has been shown to exhibit antitumor efficacy. This study aimed to investigate the effects of GS on migration and invasion and its underlying mechanisms in human GBM cell lines. After GS treatment, the survival rate of GBM cells was reduced, and the migration and invasion abilities of GBM cells were significantly decreased. There was also concomitant decreased expression of focal adhesion complex, matrix metalloproteinase-2 (MMP2), MMP9 and cathepsin B. Furthermore, GS induced ERK phosphorylation and autophagy, with increased p62 and LC3B-II expression. Notably, treatment of in GBM cells with the proteasome inhibitor MG132 or the lysosome inhibitor NH4Cl reversed the GS-mediated inhibition of migration and invasion. In an orthotopic xenograft mouse model, immunohistochemical staining of brain tumor tissues demonstrated that MMP2 and cathepsin B expression was reduced in GS-treated mice. GS treatment inhibited GBM cell migration and invasion via proteasomal and lysosomal degradation, suggesting its therapeutic potential in clinical use in the future.

Guggulsterone Induces Apoptosis in Multiple Myeloma Cells by Targeting High Mobility Group Box 1 via Janus Activated Kinase/Signal Transducer and Activator of Transcription Pathway.

Multiple myeloma (MM) is a hematological disorder characterized by the abnormal expansion of plasma cells in the bone marrow. Despite great advances over the past three decades in discovering the efficacious therapies for MM, the disease remains incurable for most patients owing to emergence of drug-resistant cancerous cells. Guggulsterone (GS), a phytosteroid, extracted from the gum resin of guggul plant, has displayed various anticancer activities in vitro and in vivo; however, the molecular mechanisms of its anticancer activity have not been evaluated in MM cells. Therefore, in this study, we investigated the anticancer activity of GS in various MM cell lines (U266, MM.1S, and RPMI 8226) and the mechanisms involved. GS treatment of MM cells caused inhibition of cell proliferation and induction of apoptotic cell death as indicated by increased Bax protein expression, activation of caspases, and cleavage of poly (ADP-ribose) polymerase. This was associated with the downregulation of various proliferative and antiapoptotic gene products, including cyclin D, Bcl-2, Bcl-xL, and X-linked inhibitor of apoptosis protein. GS also suppressed the constitutive and interleukin 6-induced activation of STAT3. Interestingly, the inhibition of Janus activated kinase or STAT3 activity by the specific inhibitors or by siRNA knockdown of STAT3 resulted in the downregulation of HMGB1, suggesting an association between GS, STAT3, and HMGB1. Finally, GS potentiated the anticancer effects of bortezomib (BTZ) in MM cells. Herein, we demonstrated that GS could be a potential therapeutic agent for the treatment of MM, possibly alone or in combination with BTZ.

Farnesoid X receptor regulates PI3K/AKT/mTOR signaling pathway, lipid metabolism, and immune response in hybrid grouper.

Some diseases related to lipid metabolism increase yearly in cultured fish, and the farnesoid X receptor (FXR) is a nuclear protein that plays a key role in inflammatory responses and lipid metabolism. However, the roles of FXR in hybrid grouper (Epinephelus fuscoguttatus♀ × E. lanceolatus♂) remain poorly understood. The main objective of this study was to explore the roles of hepatic FXR in triggering the immune response and the potential functions of FXR in regulating the lipid metabolism. In the present study, the full-length sequence of fxr from hybrid grouper was cloned and characterized for the first time. Upon the Vibrio parahaemolyticus stimulation, the transcriptional level of fxr was rapidly elevated in the head kidney tissue in the early stage of infection. In vivo and vitro, activation of FXR by obeticholic acid (OA) significantly increased the concentrations and mRNA levels of hepatic inflammatory cytokines. These effects were inversed when FXR was inhibited by guggulsterone (GU). Moreover, the activation of FXR to suppress the PI3K/AKT/mTOR signaling pathway improves hepatic lipid metabolism and reduces hepatic lipid accumulation in vivo and vitro. In addition, the inhibition of FXR activated the PI3K/AKT/mTOR pathway, decreased the lipolysis and increased the lipogenesis, and subsequently increased the lipid accumulation in fish. These results revealed the positive roles of FXR in triggering immune responses and improving lipid metabolism and accumulation in hybrid grouper.

Metabolomic profiling of Commiphora wightii (Arn.) Bhandari bark, oleogum-resin, and stem collected from different geographical regions of India

Commiphora wightii (Arn.) Bhandari (Burseraceae) produces a medicinally important oleogum-resin, extensively used by Ayurvedic physicians to treat various ailments. However, most of the studies on C. wightii have been limited to its gum resin, stem, fruit, and leaves. For the first time, comprehensive metabolomic profiling of bark was done with respect to stem and oleogum-resin, for which samples of C. wightii were collected from different geographical regions of India (Jaipur, Jodhpur, Morena, and Kutch). The samples extracted in acetonitrile showed a high concentration range of guggulsterone (GS)-E and Z in the bark (0.54 mg/g to 1.74 mg/g) as compared to the stem (0.09 mg/g to 0.39 mg/g) of C. wightii. A precise and accurate high performance liquid chromatography (HPLC) method was developed in the linear working concentration range of 7.59-30.61 µg/mL, 20.32-73.66 µg/mL with good correlations r2 0.9996 and 0.9999 for GS-E and Z in bark, respectively. Also, the hydro-alcoholic extract prepared from bark sample of each region showed a good percentage of GS-E and Z (1.66 mg/g to 3.93 mg/g). The LC-MS metabolic profiling of bark, revealed 44 common compounds with respect to oleogum-resin of C. wightii including steroids, sterols, sugars, terpenoids, flavonoids, and lignans. The present findings provide insight into important metabolites present in the bark of C. wightii such as guggulsterone-M, 6,7-dehydro-20-hydroxygugglsterone, guggulsterol-I, guggulsterol-III, guggulsterol-IV, dehydroguggulsterone-M, GS-E and Z, and these can be explored further for the development of phytopharmaceuticals, and also therapeutic utilization of bark can be done similar to oleogum-resin of C. wightii in Ayurvedic medicine.

Inonotus obliquus and its bioactive compounds alleviate non-alcoholic fatty liver disease via regulating FXR/SHP/SREBP-1c axis

Non-alcoholic fatty liver disease (NAFLD) is currently the most common chronic liver disease worldwide. However, there is still lack of specific drugs for treating NAFLD in clinic. Inonotus obliquus (IO), a folk medicinal fungus, has long been used to prevent against metabolic syndrome related diseases, such as hypertension and diabetes, etc. However, the study of IO anti-NAFLD effect has been reported rarely. This study aimed to investigate whether IO has an inhibitory effect on NAFLD, identify the active compounds in IO and clarify the underlying mechanisms of its anti-NAFLD effects. The results of Oil Red O(ORO) and Hematoxylin-Eosin (HE) staining, lipid extraction and determination showed that IO and its extracts, including inotodiol (Ino), lanosterol (Lan) and trametenolic acid (TA), could remarkably ameliorate lipid accumulation in MCD diet-induced mouse livers or OA-induced LO2 hepatocytes. Moreover, qPCR analysis revealed that IO and its compounds significantly downregulated the mRNA levels of lipogenic genes, such as SREBP-1c, ACC1 and FASN, and upregulated the mRNA levels of FXR and SHP. We found that the administration of guggulsterone (GS), a FXR inhibitor, abolished the inhibitory effect of Ino on lipid deposition in OA-induced LO2 cells. In conclusion, IO and its compounds attenuate hepatic lipid accumulation in NAFLD by inhibiting liver lipogenesis. The anti-NAFLD effects of Ino, a bioactive compound in IO, are through regulating FXR/SHP/SREBP-1c pathway. Our results suggested that IO and its bioactive compound Ino may become promising drugs to treat NAFLD.

Guggulsterone Mediated JAK/STAT and PPAR-Gamma Modulation Prevents Neurobehavioral and Neurochemical Abnormalities in Propionic Acid-Induced Experimental Model of Autism.

Autism spectrum disorder is a neurodevelopmental disorder marked by repetitive behaviour, challenges in verbal and non-verbal communication, poor socio-emotional health, and cognitive impairment. An increased level of signal transducer and activator of transcription 3 (STAT3) and a decreased level of peroxisome proliferator-activated receptor (PPAR) gamma have been linked to autism pathogenesis. Guggulsterone (GST) has a neuroprotective effect on autistic conditions by modulating these signalling pathways. Consequently, the primary objective of this study was to examine potential neuroprotective properties of GST by modulating JAK/STAT and PPAR-gamma levels in intracerebroventricular propionic acid (ICV PPA) induced experimental model of autism in adult rats. In this study, the first 11 days of ICV-PPA injections in rats resulted in autism-like behavioural, neurochemical, morphological, and histopathological changes. The above modifications were also observed in various biological samples, including brain homogenate, CSF, and blood plasma. GST was also observed to improve autism-like behavioural impairments in autistic rats treated with PPA, including locomotion, neuromuscular coordination, depression-like behaviour, spatial memory, cognition, and body weight. Prolonged GST treatment also restored neurochemical deficits in a dose-dependent manner. Chronic PPA administration increased STAT3 and decreased PPAR gamma in autistic rat brain, CSF, and blood plasma samples, which were reversed by GST. GST also restored the gross and histopathological alterations in PPA-treated rat brains. Our results indicate the neuroprotective effects of GST in preventing autism-related behavioural and neurochemical alterations.

Study The Anti-Asthmatic Activity of Guggulsterone In Ovalbumin-Induced Asthma In Rat

Asthma is a chronic in?ammatory respiratory disease associated with the changes of asthmatic airway structural that result from interact remodeling and in?ammatory processes lead to obstruction of airway. Guggulsterone (GS) is a bioactive compound and plant steroid present in guggul gum of Commiphora wightii, which has anti-inflammatory and antioxidant activities. This study designed to investigate of anti-inflammatory activity of gugglsterone in improvement of asthma. Forty eight healthy albino male rats divided to six groups, Group I: Control group (distal water), Group II: Positive control group (distal water) with sensitization, Group III: Guggulsterone (25 mg/kg/day) with sensitization, Group IV: Guggulsterone (50 mg/kg/day) with sensitization, Group V: Prednisolone (4.12 mg/kg/day) with sensitization, Group VI: Guggulsterone (50mg/kg/day) without sensitization. Rats were sacrificed and blood samples were collected to prepare of serum samples that used in ELISA kits for measuring of IL-4, IL-5, IL-33, TNF 
 IgE. In addition, WBC counts in Bronchoalveolar lavage fluid. ALL parameters (IL-4, IL-5, IL-33, TNF, & IgE) levels for rats of treated groups with gugglsterone were significant (P<0.05) reduced in compared to sensitized group. Similarly, WBC count for rats treated groups with guggulsterone was significantly (P<0.05) fewer than sensitized group. In conclusion, our results provide a clue that guggulsterone has a potent anti-inflammatory activity that improved OVA-induced asthma and is useful for the preventive of allergic airway disease in rodents.

Synthetic E-guggulsterone derivative GSD-1 inhibits NF-κB signaling and suppresses the metastatic potential of breast cancer cells

Guggulsterone (GS) [4,17(20)-pregnadiene-3,16-dione], is the main active phytosterol constituent in guggul, the gum resin of Commiphora wightii (Arnott.) Bhand./Commiphora mukul Engl. tree, and is known for its medicinal effects. In this study, we report that GSD-1, a structurally-related synthetic GS derivative, strongly inhibits NF-κB activation induced by TNF-α. GSD-1 prevented the nuclear translocation of p65 through the blockade of IκBα degradation and p65 phosphorylation, and further inhibited the activation of upstream kinases, including transforming growth factor-β activated kinase 1 (TAK1), IκB kinase (IKK) α, and IKKβ. Furthermore, GSD-1 inhibited the cell-intrinsic activation of NF-κB, and exerted its direct anti-cancer and anti-metastatic effects in both murine and human breast cancer cell lines. This study demonstrated GSD-1 to be an attractive compound to target NF-κB activation that has potential for treating breast cancer growth and metastasis.

Guggulsterone induces apoptosis and inhibits lysosomal-dependent migration in human bladder cancer cells

BackgroundThe survival rate and therapeutic options for patients with bladder cancer have improved little in recent decades. Guggulsterone (GS), a phytoestrogen, has been investigated as an anticancer drug in various malignancies. PurposeThe present study aimed to evaluate the anticancer effects of E-isomer and Z-isomer GS in the human bladder cancer cell lines TSGH8301 (low-grade) and T24 (high-grade) and their underlying mechanisms. MethodsThe cell survival effect of GS was investigated by the MTT and colony formation assays in bladder cancer cell lines. Flow cytometry was used to analyze the cell cycle and cell death. Migration ability was measured by wound healing and transwell assays. Protein expression was determined by Western blot after GS treatment. The potency of GS on subcutaneous TSGH8301 bladder tumors was evaluated using an in vivo imaging system. ResultsE-isomer GS reduced the survival rate of both low- and high-grade human bladder cancer cells. GS caused cell cycle arrest, accompanied by the decrease and increase in cyclin A and p21 levels, respectively. Additionally, caspase-dependent apoptosis was observed following GS treatment. Furthermore, GS treatment downregulated mTOR-Akt signaling and induced autophagy with p62 and LC3β-II expression. Moreover, the farnesoid X receptor was involved in GS-inhibited cell growth. In addition, GS reduced the migration ability with a decrease in integrin-focal adhesion kinase and myosin light chain. Interestingly, the suppression of GS-mediated migration was prevented by the lysosomal inhibitor ammonium chloride (NH4Cl). GS also reduced TSGH8301 bladder cancer cell progression by increasing the level of p21, cleaved caspase 3, cleaved poly (ADP-ribose) polymerase (PARP), and LC3β-II in vivo. ConclusionsThe current findings suggest that GS treatment may serve as a potential anticancer therapy for different grades of urothelial carcinoma.

Therapeutic use of Guggulsterone in COVID-19 induced obesity (COVIBESITY) and significant role in immunomodulatory effect.

COVID-19 has emerged as a major cause of health crisis around the world. Psychosocial, Behavioral and metabolic changes especially weight gain, among variety of population was produced in this pandemic, through variety of mechanisms. Hyperlipidemia is one of the major issues that result in serious cardiovascular complications. Governmental strategies to minimize the spread of COVID-19 through closures, lockdowns, and alterations in social interaction have complicated weight management efforts. And immunity being the need of the hour has to be improved to prevent the infection. Guggulsterone (GS) isomers are major bioactive compounds present in Commiphora mukul and Commiphora wighti. Guggulsterone shows anti-hyperlipidemic, anti-oxidant, anti-inflammatory, immunomodulatory and appetite regulating activity due to its peculiar characteristics. On the basis of clinical evidence, Guggulsterone seems to possess good cholesterol lowering, appetite regulating as well as immunomodulatory activity which can be beneficial during the pandemic of COVID-19.

Guggulsterone ameliorates ethidium bromide-induced experimental model of multiple sclerosis via restoration of behavioral, molecular, neurochemical and morphological alterations in rat brain.

Multiple Sclerosis (MS) is a progressive neurodegenerative disease with clinical signs of neuroinflammation and the central nervous system's demyelination. Numerous studies have identified the role of the Janus kinase (JAK)/signal transducer and activator of transcription (STAT) overexpression and the low level of peroxisome proliferator-activated receptor-gamma (PPAR-γ) in MS pathogenesis. Guggulsterone (GST), an active component derived from 'Commiphora Mukul,' has been used to treat various diseases. Traditional uses indicate that GST is a suitable agent for anti-inflammatory action. Therefore, we assessed the therapeutic potential of GST (30 and 60mg/kg) in ethidium bromide (EB) induced demyelination in experimental rats and investigated the molecular mechanism by modulating the JAK/STAT and PPAR-γ receptor signaling. Wistar rats were randomly divided into six groups (n = 6). EB (0.1%/10μl) was injected selectively in the intracerebropeduncle (ICP) region for seven days to cause MS-like manifestations. The present study reveals that long-term administration of GST for 28days has a neuroprotective effect by improving behavioral deficits (spatial cognition memory, grip, and motor coordination) associated with lower STAT-3 levels. While elevating PPAR-γ and myelin basic protein levels in rat brains are consistent with the functioning of both signaling pathways. Also, GST modulates the neurotransmitter level by increasing Ach, dopamine, serotonin and by reducing glutamate. Moreover, GST ameliorates inflammatory cytokines (TNF, IL-1β), and oxidative stress markers (AchE, SOD, catalase, MDA, GSH, nitrite). In addition, GST prevented apoptosis, as demonstrated by the reduction of caspase-3 and Bax. Simultaneously, Bcl-2 elevation and the restoration of gross morphology alterations are also recovered by long-term GST treatment. Therefore, it can be concluded that GST may be a potential alternative drug candidate for MS-related motor neuron dysfunctions.

Effect of aging and geographical variations in the content of guggulsterones and metabolomic profiling of oleogum resins of commiphora wightii: The Indian bdellium

Background: The oleo-gum resin of Commiphora wightii has been utilized for centuries in Ayurvedic medicine for the treatment of various diseases. Ruthless exploitation of this species with negligible conservation efforts has led to its inclusion in the International Union for Conservation of Nature assemblage of endangered plant species. Objectives: In this paper, the impact of plant aging and geographical variations of guggulsterone (GS) content in oleo-gum resin collected from different geographical regions of India has been examined. Materials and Methods: The oleo-gum resin samples of different age groups and geographical regions of India (Kutch, Morena, Jodhpur, Jaipur, and Pakistan border of Kutch) were collected directly from the site and examined to check the concentration of GS-E and Z by high-performance liquid chromatography. Comprehensive metabolomic profiling of samples was done through liquid chromatography–mass spectrometry. Results: The data showed that there is no significant variation was found in the concentration of GS-E and Z with the change in the age of C. wightti plant. The oleo-gum resin samples of Morena showed a high percentage range of GSs (0.88%–2.17% w/w), whereas Jaipur samples showed a lower percentage of GSs (0.56%–0.89% w/w). From metabolomics profiling, 11 high-intensity metabolites were identified in samples of all major regions of India. Conclusion: This study indicates that there is no impact of plant aging on the GS contents. The Indian regions such as Morena, Kutch, and Pakistan border near Kutch regions can be used as a potential source for mass multiplication of guggul plants to get the good quality of the oleo-gum resin.

Therapeutic Effect of Guggulsterone in Primary Cultured Orbital Fibroblasts Obtained From Patients with Graves' Orbitopathy.

PurposeInflammation, hyaluronan production, and adipogenesis are the main pathological events leading to Graves’ orbitopathy (GO). Guggulsterone (GS), a phytosterol found in the resin of the guggul plant, is a well-known treatment for several inflammatory disorders, such as arthritis, obesity, and hyperlipidemia. Here we investigated the effects of GS treatment on GO pathology.MethodsUsing primary cultures of orbital fibroblasts from GO patients and non-GO controls, we examined the effects of GS on hyaluronan production and the production of proinflammatory cytokines induced by interleukin (IL)-1β, using real-time reverse transcription-polymerase chain reaction analysis, western blots, and enzyme-linked immunosorbent assays. Further, adipogenic differentiation was evaluated by quantification of Oil Red O staining and assessment of protein levels of peroxisome proliferator activator gamma (PPARγ), CCAAT-enhancer-binding proteins (C/EBP) α and β, and sterol regulatory element-binding protein-1 (SREBP-1).ResultsTreatment with noncytotoxic concentrations of GS resulted in the dose-dependent inhibition of IL-1β-induced inflammatory cytokines, including IL-6, IL-8, MCP-1, and COX-2, at both mRNA and protein levels. The hyaluronan level was also significantly suppressed by GS. Moreover, GS significantly decreased the formation of lipid droplets and expression of PPARγ, C/EBP α/β, and SREBP-1 in a dose-dependent manner. GS pretreatment attenuated the phosphorylation of nuclear factor-kappa B induced by IL-1β.ConclusionsOur data show significant inhibitory effects of GS on inflammation, production of hyaluronan, and adipogenesis in orbital fibroblasts. To our knowledge, this is the first in vitro preclinical evidence of the therapeutic effect of GS in GO.
