Abstract
Helicteres angustifolia L. (Helicteres angustifolia) has been commonly used in folk medicine to treat cancer; however, its mechanisms of action remain obscure. In our earlier work, we reported that aqueous extract of H. angustifolia root (AQHAR) possesses attractive anticancer properties. In the present study, we isolated five ethanol fractions from AQHAR and investigated their therapeutic efficacy in human non-small cell lung cancer (NSCLC) cells. The results showed that among the five fractions, the 40% ethanol fraction (EF40) containing multiple bioactive compounds exhibited the best selective killing effect on NSCLC cells with no obvious toxicity to normal human fibroblasts. Mechanistically, EF40 reduced the expression of nuclear factor-E2-related factor 2 (Nrf2), which is constitutively expressed at high levels in many types of cancers. As a result, Nrf2-dependent cellular defense responses are suppressed, leading to the intracellular accumulation of reactive oxygen species (ROS). Extensive biochemical analyses revealed that EF40 caused cell cycle arrest and apoptosis through activation of the ROS-mediated DNA damage response. Furthermore, treatment with EF40 compromised NSCLC cell migration, as evidenced by the downregulation of matrix metalloproteinases (MMPs) and heterogeneous nuclear ribonucleoprotein K (hnRNP-K). In vivo studies using A549 xenografts in nude mice also revealed significant suppression of tumor growth and lung metastasis in the treated group. We propose that EF40 may serve as a potential natural anti-NSCLC drug that warrants further mechanistic and clinical attention.

Abstract
This study aimed to investigate the effect and underlying mechanism of Methyl helicterilate from Helicteres angustifolia (MHHA) on alcohol-induced hepatic fibrosis. The results showed that MHHA treatment markedly alleviated alcohol-induced liver injury and notably reduced collagen deposition in liver tissue. It significantly enhanced the activity of alcohol dehydrogenase and aldehyde dehydrogenase. Moreover, MHHA treatment markedly decreased the content of inflammatory cytokines, alleviated collagen accumulation, and inhibited the expression of TGF-β1 and Smad2/3 in liver tissue. The experiments in cells showed that MHHA significantly inhibited HSC activation by blocking TGF-β1/Smads signaling pathway. Additionally, it notably induced HSC apoptosis by modulating the mitochondria-dependent pathway. The present study demonstrates that MHHA treatment significantly ameliorates alcoholic hepatic fibrosis and the underlying mechanism may be ascribed to the inhibition of the TGF-β1/Smads pathway and regulation of the mitochondria-mediated apoptotic pathway.

Int Immunopharmacol 2018; 66:41-51.

Abstract
Methyl helicterate (MH) has been reported to have protective effects against CCl4-induced hepatic injury and fibrosis in rats, but its protective mechanism, especially on hepatic stallete cells (HSCs), remains unclear. Recently, our pilot experiment showed that MH could inhibit miR-21 expression in HSC-T6 cells, suggesting that miR-21 may be one of the targets of MH to intervene liver fibrosis. To verify the hypothesis, the present study would focus on the regulatory effect of MH on the miR-21-mediated ERK and TGF-β1/Smads pathways. Briefly, rats were intraperitoneally injected with 0.5 ml porcine serum (PS) twice a week for 24 weeks to induce liver fibrosis, and meanwhile, the rats were treated with MH from weeks 16 to 24. In vitro experiment, miR-21 expression in HSC-T6 cells was up- or down-regulated using lentiviral transfection assay. Collagen accumulation, inflammatory cytokines, cell apoptosis, miR-21 expression, and activation of the ERK and TGF-β1/smad2/3 pathways were then assessed. The results showed that MH treatment markedly alleviated PS-induced liver injury, as evidenced by the attenuation of histopathological changes and the decrease in serum alanine and aspartate aminotransferases activity. MH significantly decreased the content of inflammatory cytokines and recruited the anti-oxidative defense system. Moreover, MH treatment significantly decreased miR-21 expression and inhibited the activation of the ERK and TGF-β1/smad2/3 pathways in liver tissues. In vitro experiments showed that MH strongly inhibited HSC-T6 cell activation and reduced collagen accumulation. Interestingly, miR-21 overexpression significantly promoted HSC-T6 cell proliferation, reduced HSC apoptosis, and increased collagenation, while these abnormal changes induced by miR-21overexpression were significantly reversed by MH treatment. Furthermore, miR-21 overexpression notably activated the ERK and TGF-β1/Smads pathways via repressing SPRY2 and Smad7 expression respectively, however, these effects were largely abolished by MH treatment. In conclusion, our study demonstrates that MH significantly alleviates PS-induced liver injury and fibrosis by inhibiting miR-21-mediated ERK and TGF-β1/Smads pathways.

Abstract
Liver diseases are one of the leading causes of death in the world. In spite of tremendous advances in modern drug research, effective and safe hepatoprotective agents are still in urgent demand. Natural products are undoubtedly valuable sources for drug leads. A number of natural triterpenoids were reported to possess pronounced hepatoprotective effects, and triterpenoids have become one of the most important classes of natural products for hepatoprotective agents. However, the significance of natural triterpenoids has been underestimated in the hepatoprotective drug discovery, with only very limited triterpenoids being covered in the reviews of hepatoprotective natural products. In this paper, ca 350 natural triterpenoids with reported hepatoprotective effects in ca 120 references between 1975 and 2016 will be reviewed, and the structure-activity relationships of certain types of natural triterpenoids, if available, will be discussed. Patents are not included.

Abstract
The present study aimed to explore the treatment effects of Taohongsiwu decoction on the liver fibrosis in a rat model, as few prior studies have investigated the anti-fibrotic effects of Taohongsiwu decoction. High-performance liquid chromatography was used to measure the concentration of ferulic acid and hydrosafflower flavin A in the decoction. Male Sprague-Dawley rats were randomly divided into control, model, colchicine (positive group), Taohongsiwu-high, Taohongsiwu-moderate and Taohongsiwu-low groups; 50% carbon tetrachloride (CCl4) of peanut oil solution was subcutaneously injected to the rats except for the control group, and the drugs were intragastrically administered (10 ml/kg) starting at week 7 for 6 continuous weeks. The rats were deprived of food but not water for 12 h following the final administration, then blood was collected from the abdominal aorta. The liver tissues were obtained, fixed with 10% neutral formaldehyde, and embedded with paraffin. The concentrations of ferulic acid and hydroxysafflor flavin A in Taohongsiwu decoction were 0.12 and 0.57 mg/ml, respectively. The three groups treated with Taohongsiwu decoction were found with significantly lower serum levels of aspartate aminotransferase, alanine amino transferase, collagen IV and hyaluronic acid, as well as higher level of albumin (ALB); in addition, the expression levels of α-smooth muscle actin (α-SMA) and transforming growth factor-β1 (TGF-β1) mRNA and collagen I were significantly downregulated. Taohongsiwu decoction improved the liver function, reduced the collagen deposition in the serum and liver tissues, and inhibited the expression of α-SMA and TGF-β1.

Abstract
Hepatic fibrosis is a reversible pathological process, in which fibrotic tissue is excessively deposited in the liver during the repair process that follows hepatic injury. Early prevention or treatment of hepatic fibrosis has great significance on the treatment of chronic hepatic diseases. Hydroxysafflor yellow A (HSYA) is a water-soluble monomer extracted from safflower, which serves numerous pharmacological roles. However, it remains to be elucidated how HSYA regulates hepatic fibrogenesis. The aim of the present study was to reveal the possible mechanisms underlying the effects of HSYA on the prevention and treatment of hepatic fibrosis. A rat model of hepatic fibrosis was established in the present study, and the rats were administered various doses of HSYA. The effects of HSYA on pathological alterations of the liver tissue in rats with hepatic fibrosis were observed using hematoxylin-eosin staining and Masson staining. In order to explore the anti-hepatic fibrosis effects and underlying mechanisms of HSYA, serum levels, and hepatic function and hepatic fibrosis indices were evaluated. The results demonstrated that HSYA can improve the general condition of rats with hepatic fibrosis and relieve cellular swelling of the liver, fatty degeneration, necrosis, inflammatory cell infiltration and fibroplastic proliferation. Subsequent to administration of HSYA, globulin was increased during hepatic fibrosis caused by tetrachloromethane. However, total cholesterol, triglyceride, alanine aminotransferase, aspartate aminotransferase and levels of hyaluronic acid, laminin, procollagen III N-terminal peptide, collagen type IV and hydroxyproline were significantly reduced. The results additionally demonstrated that HSYA could enhance superoxide dismutase activity and reduce malondialdehyde levels, inhibiting lipid peroxidation caused by free radicals.

Abstract
Context The root of Helicteres angustifolia L. (Sterculiaceae) has been used as folk herbal drug to treat cancer, bacterial infections, inflammatory, and flu in China. However, there is no report on its antidiabetic activity. Objective This study evaluates the antidiabetic activity of ethanol extract from H. angustifolia root. Materials and methods The promoting effect of H. angustifolia root ethanol extract (25, 50, and 100 μg/mL) on glucose uptake was evaluated using HepG2 cell, differentiated C2C12 myotubes, and differentiated 3T3-L1 adipocytes. The antidiabetic activity of the extract was assessed in vivo using STZ-induced diabetic rats by orally administration of the extract (200 and 400 mg/kg b.w.) once per day for 28 d. Blood glucose, TG, TC, TP, HDL-C, UA, BUN, AST, ALT, insulin, and HOMA-IR were analyzed. Results The results showed that the extract increased glucose uptake in C2C12 myotubes and 3T3-L1 adipocytes with an IC50 value of 79.95 and 135.96 μg/mL, respectively. And about 12%, 19%, and 10% (p < 0.05) in HepG2 cells when compared with the control at the concentration of 25, 50, and 100 μg/mL, respectively. After 28 days' treatment with the extract, significant reduction was observed in blood glucose, HOMA-IR, TC, TG, UA, BUN, AST, and ALT levels, while the levels of TP and HDL cholesterol increased. Discussion and conclusion These results suggest that H. angustifolia root ethanol extract possess potent antidiabetic activity, which is the first report on antidiabetic activity of this plant.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Helicteres sacarolha A. St.- Hil. et al. popularly known in Brazil as 'semente-de-macaco', is widely employed in the popular medicine in many of parts of Brazil in the alleviation of symptoms of ailments such as peptic ulcer and inflammation. Up to the present, there is no study addressing the gastroprotective activity of the hydroethanolic extract of H. sacarolha and its possible mechanism of actions. MATERIALS AND METHODS The hydroethanolic (70%) extract of H. sacarolha (HEHs) was obtained by maceration. The gastroprotective activity was assessed using gastric ulcer models induced by acidified ethanol, piroxicam, and water restraint stress in mice and rats at doses of 20, 50 and 250mg/kg p.o. Mechanistic studies involved the antisecretory assay evaluated with pylorus ligation in rats and pre-treatments with appropriate antagonists/inhibitors such as yohimbine, glibenclamide, indomethacin and l-NAME, effect on catalase and myeloperoxidase activities and gastric mucus determination using acidified ethanol- induced ulcer in mice. RESULTS HEHs at all doses tested demonstrated potent gastroprotective activities in the acute ulcer models. The gastroprotective activity of HEHs was attenuated by pre-treatments with yohimbine, glibenclamide, indomethacin and l-NAME. HEHs effectively reduced basal gastric juice production without any effect on the free and total acidity. The gastroprotective action of HEHs involved increasing the antioxidant enzyme catalase and mucus secretion and inhibition of neutrophyl infiltration as reflected by the reduction in the myeloperoxidase activity. CONCLUSION The results of this study gave a scientific support for the popular use of the leaves of H. sacarolha in the treatment of gastric ulcers and that it has a multi-targeted action.

Protective effects of hydroxysafflor yellow A (HSYA) on alcohol-induced liver injury in rats. J Physiol Biochem 2015; 71:69-78. [PMID: 25626885 DOI: 10.1007/s13105-015-0382-3] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2014] [Accepted: 01/14/2015] [Indexed: 12/24/2022]
Abstract
Hydroxysafflor yellow A (HSYA), the main active natural constituent extracted from Carthamus tinctorius L., has been widely used for the treatment of cerebrovascular and cardiovascular diseases. The aim of this study is to explore the effect of HSYA on alcohol-induced liver injury and the underlying mechanism. Male Sprague-Dawley rats were used to establish the liver injury model induced by alcohol. HSYA treatment ameliorated serum biochemical indicators by reducing the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), hyaluronan (HA), laminin (LN), and type III precollagen (III-C) in rats. HSYA efficiently increased the activity and messenger RNA (mRNA) of superoxide dismutase (SOD) and glutathione peroxidase (GPx) in rat liver tissue compared with those of model group, which was obviously reduced by alcohol. HSYA also apparently decreased the levels of reactive oxygen species (ROS) and malondialdehyde (MDA) in rat liver tissue compared with those of model group, which was obviously enhanced by alcohol. Histological studies demonstrated that HSYA substantially reduced the number of macro- and micro-vesicular steatosis, suppressed hepatic fibrogenesis and shrunk ballooning degeneration areas, ameliorated the severity of liver damage induced by long-term drinking, and finally improved the liver architecture. In addition, immunohistochemistry study indicated that the activation of transforming growth factor β1 (TGF-β1) stimulated by alcohol in rat liver tissue was significantly blocked by HSYA. Collectively, these data demonstrated that HSYA can effectively protect the liver of rats from long-term alcohol injury, which relates with the enhanced antioxidant capacity of liver tissues and inhibition of TGF-β1 expression.

Antiviral activity of methyl helicterate isolated from Helicteres angustifolia (Sterculiaceae) against hepatitis B virus. Antiviral Res 2013; 100:373-81. [PMID: 24055834 DOI: 10.1016/j.antiviral.2013.09.007] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2013] [Revised: 08/16/2013] [Accepted: 09/10/2013] [Indexed: 12/17/2022]
Abstract
The anti-HBV effect of methyl helicterate (MH), a triterpenoid isolated from the Chinese herb Helicteres angustifolia, was explored both in vitro and in vivo. In the HBV-transfected cell line HepG2.2.15, the secretion of HBsAg/HBeAg, the levels of HBV DNA and cccDNA, and the amount of viral RNA were significantly decreased after treatment with MH for 144h. In addition, MH had no inhibitory effect on the mitochondrial DNA content. In DHBV-infected ducklings, MH significantly reduced the serum DHBV DNA, liver total viral DNA, and cccDNA levels. Furthermore, analysis of the liver pathological changes confirmed the hepatoprotective effect of MH. These results indicate that MH efficiently inhibits HBV replication both in vitro and in vivo and that MH may be a major bioactive ingredient in H. angustifolia.
