Biological Activity
Description: Niga-ichigoside F1(NI) has anti-inflammatory, gastroprotective ,antinociceptive, and cytotoxic effects. NI showed an inhibition zone on β-glucosidase and anti-acetylcholinesterase assays. The dietary NI could prevent HFD-induced hepatic steatosis, possibly via interacting with HFD to activate Nrf2 nuclear translocation to maintain a redox status, thus regulating lipid metabolism genes expressions.
Targets: Nrf2 | NO | SOD | GPx | CAT

Biological activities of triterpenoids from Poraqueiba sericea stems.[Pubmed: 27736194 ]
Eleven compounds were isolated from Poraqueiba sericea stems and identified as Niga-ichigoside F1 (1), trachelosperoside B1 (2), 4-epi-niga-ichigoside (7), 19α-hydroxyasiatic acid (3), myrianthic acid (4), hyptatic acid (5), trachelosperogenin B (6), arjunolic acid (8), and trachelosperogenin E (9), secologanoside (10) and secoxyloganin (11).
METHODS AND RESULTS:
Compounds 1-11 were tested for their antileishmanial activities against Leishmania infantum promastigotes, 1-6 and 8-11 were tested for their cytotoxic activities on fibroblasts, 1-3, 5-6, 8-11 were evaluated for their anti-elastase and anti-acetylcholinesterase assays activities by a spectrophotometric method and 1-2, 5 and 7-10 were tested using bioautography for their β-glucosidase.
CONCLUSIONS:
No antileishmanial activity was detected; compounds 1, 2 and 11 showed a moderate cytotoxic activity with IC50 17.7, 20.5 and 10.9 μg/mL, respectively; compounds 2, 8, 9 and 10 gave a percentage of inhibition ranging from 13 to 16% (at 50 μg/mL) and compounds 1 and 2 showed an inhibition zone on β-glucosidase and anti-acetylcholinesterase assays.

Rubus imperialis (Rosaceae) extract and pure compound niga-ichigoside F1: wound healing and anti-inflammatory effects.[Pubmed: 27527496 ]
Here, we evaluate the anti-inflammatory and wound-healing effects of methanolic crude extract obtained from aerial parts (leaves and branches) of Rubus imperialis Chum. Schl. (Rosaceae) and the pure compound Niga-ichigoside F1.
METHODS AND RESULTS:
Anti-inflammatory activity was determined in vivo and in vitro, and the healing effect was evaluated in surgical lesions in mice skin. The 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) assay and H2O2-induced oxidative stress were used to determine antioxidant activity. The efferocytosis activity was also determined. The data obtained show that the extract of R. imperialis promote reduction in the inflammatory process induced by lipopolysaccharide (LPS) or carrageenan in the air pouch model; the effects could be reinforced by nitric oxide reduction in LPS-stimulated neutrophils, and an increase in the efferocytosis. The extract showed wound healing property in vitro and in vivo, scavenging activity for DPPH, and cytoprotection in the H2O2-induced oxidative stress in L929 cells. In addition, the compound Niga-ichigoside F1 was able to reduce the NO secretion; however, it did not present wound-healing activity in vitro.
CONCLUSIONS:
Together, the data obtained point out the modulatory actions of R. imperialis extract on leukocyte migration to the inflamed tissue, the antioxidant, and the pro-resolutive activity. However, the R. imperialis anti-inflammatory activity may be mediated in parts by Niga-ichigoside F1, and on wound healing do not correlated with Niga-ichigoside F1.

Evaluation of the gastroprotective activity of the extracts, fractions, and pure compounds obtained from aerial parts of Rubus imperialis in different experimental models.[Pubmed: 24402081 ]
Previous phytochemical studies carried out with Rubus imperialis Chum. Schl. (Rosaceae) have demonstrated the presence of triterpenes (Niga-ichigoside F1 and 2β,3β,19α-trihydroxyursolic acid) in this species. The literature indicates that triterpenes are closely related to some pharmacological activities, including antiulcer activity. Therefore, in view of the previous promising results with this species, this work extends the phytochemical studies, as well as investigates its gastroprotective action in different models using rodents.
METHODS AND RESULTS:
The hydroalcoholic extract was tested using the following protocols in mice: ethanol/HCl and nonsteroidal anti-inflammatory drug (NSAID)-induced ulcer, acetic acid-induced chronic ulcer, ligature pylorus model, and free mucus quantification in mucosa. Isolated triterpenes were investigated in the ethanol/HCl-induced ulcer model. The results of this study show that R. imperialis extract (100, 250, or 500 mg) displays gastroprotective activity in the ethanol-induced ulcer model with a percentage of inhibition of gastric lesions of 70, 71, and 86 %, respectively. The extract also significantly reduced the ulcerative lesions in the indomethacin-induced ulcer. In this model, the percentage of inhibition of ulcer was 41, 44, and 70 %, respectively. Regarding the model of gastric secretion, a reduction of gastric juice volume and total acidity was observed, as well as an increase in gastric pH; however, gastric mucus production was not altered by treatment with the extract. It was also observed that the ethyl acetate fraction presented higher activity, leading to the isolation of Niga-ichigoside F1 and 2β,3β-19-α-trihydroxyursolic acid, which presented antiulcer activity comparable to that of omeprazole, with an inhibition percentage of 98 and 99 %, respectively.
CONCLUSIONS:
These results demonstrate that R. imperialis extract and isolated compounds (Niga-ichigoside F1 and 2β,3β-19-α-trihydroxyursolic acid) produce gastroprotective effects, and this activity seems, at least in part, to be related to antisecretory effects.

Niga-ichigoside F1 ameliorates high-fat diet-induced hepatic steatosis in male mice by Nrf2 activation.[Pubmed: 29309075 ]
Hepatic lipid accumulation and oxidative stress (OS) lead to non-alcoholic fatty liver disease (NAFLD). Thus, we hypothesized that antihyperlipidemic and antioxidant activities of Niga-ichigoside F1 (NI) would ameliorate events leading to NAFLD. Lanbuzheng (Geum japonicum Thunb. var. chinense), a type of wild vegetable found in Southwest China, was used to extract NI.
METHODS AND RESULTS:
Male C57BL/6J mice were fed a standard diet (Con) or a high-fat diet (HFD) (denoted as diet) with or without 40 mg kg-1 NI (defined as treatment) for 12 weeks. Diet-treatment interactions were observed in the final body weight, fat pad mass, respiratory exchange ratio (RER) in the daytime, and energy expenditure during the whole day. Moreover, NI alleviated hepatic steatosis, possibly by significantly interacting with HFD to regulate lipid metabolism genes (including Srebp1c, Acc1, Fasn, Scd1, Cpt1a and Fabp5). We also found significant diet-treatment interactions on superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) activities, and thiobarbituric acid reactive substance (TBARS) levels, as well as the nuclear and cellular Nrf2 protein levels. Significant free fatty acid (FFA)-treatment interactions on Nrf2 nuclear translocation, antioxidant enzymes activities, genes in lipogenesis (Srebp1c, Acc1, Fasn, and Scd1), and fatty acid oxidation (Pparα) and transport (Fabp5 and Cd36) were also detected in 1 mM FFA-treated HepG2 cells with or without 20 μM NI. These beneficial effects of NI on oxidative stress and lipid accumulation were abolished by Nrf2 siRNA.
CONCLUSIONS:
Our data revealed that dietary NI could prevent HFD-induced hepatic steatosis, possibly via interacting with HFD to activate Nrf2 nuclear translocation to maintain a redox status, thus regulating lipid metabolism genes expressions.

Analysis of the mechanism of antinociceptive action of niga-ichigoside F1 obtained from Rubus imperialis (Rosaceae).[Pubmed: 17331332 ]
We have previously verified that Niga-ichigoside F1 (NI), a triterpene isolated from Rubus imperialis, exhibits significant and potent antinociceptive action when evaluated in some pharmacological models of pain in mice. This effect was confirmed in other experimental models and also the mechanism of action has been evaluated.
METHODS AND RESULTS:
The antinociception caused by NI (60 mg kg(-1)) in both phases of the formalin test was significantly attenuated by intraperitoneal injection of mice with haloperidol (a dopaminergic antagonist, 0.20 mg kg(-1)) and L-arginine (precursor of nitric oxide, 600 mg kg(-1)). Regarding the cholinergic system, atropine (a cholinergic antagonist 60 mg kg(-1)) reverted only the second phase. The effect of NI was not affected by treatment of mice with yohimbine (an alpha2-adrenoceptor antagonist, 0.15 mg kg(-1)). The same pharmacological profile was observed for the administration of naloxone (an opioid receptor antagonist, 1 mg kg(-1)). On the other hand, intraperitoneal injection caused dose-related and significant effects against glutamate- and capsaicin-induced pain, respectively.
CONCLUSIONS:
In conclusion, the marked antinociception of NI appears to be related to the dopaminergic, cholinergic, glutamatergic, tachykininergic and oxinitrergic systems, supporting the ethnomedical use of Rubus imperialis (Rosaceae).
