Abstract
Shell ginger (Alpinia zerumbet) is a perennial ornamental plant of ginger native to East Asia, which can be used as a flavoring agent in food or beverage, as well as a traditional Chinese medicine. In this study, a total of 37 terpenoids, including 7 new compounds, zerumin D1 to zerumin D7 (2, 3, 28-30, 36, and 37), and 5 new naturally occurring compounds, zerumin D10 to zerumin D14 (9, 12, 15, 20, and 24), were isolated and identified from the rhizomes of shell ginger. Compound 3 was an unprecedented variant labdane diterpenoid featuring a unique 6/7/6/3 tetracyclic cyclic ether system in its side chain. The anti-inflammatory activities of the isolated terpenoids were assessed in RAW 264.7 macrophages stimulated by lipopolysaccharide (LPS). Compound 4 significantly inhibited the production of nitric oxide with an IC50 value of 5.4 μM. Further investigation revealed that compounds 2 and 3 may inhibit the nuclear translocation of NF-κB, thus suppressing the expression of IL-6, IL-1β, iNOS, and COX-2 to exert the anti-inflammatory effects.

Protective effects of Rubus tereticaulis leaves ethanol extract on rats with ulcerative colitis and bio-guided isolation of its active compounds: A combined in silico, in vitro and in vivo study. Chem Biol Interact 2023; 369:110263. [PMID: 36375516 DOI: 10.1016/j.cbi.2022.110263] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2022] [Revised: 11/01/2022] [Accepted: 11/11/2022] [Indexed: 11/13/2022]
Abstract
The aim of this study was to evaluate the therapeutic effect of active ethanol extract obtained from the leaves of Rubus tereticaulis (RTME) against colitis, and to purify major compounds from this extract by bioassay-directed isolation. Rats with colitis induced via intra-rectal acetic acid administration (5%, v/v) received RTME or sulfasalazine for three consecutive days. On day four, all rats were decapitated, and the colonic tissue samples were collected for macroscopic score, colon weight, reduced glutathione (GSH), myeloperoxidase (MPO), and malondialdehyde (MDA) analyses. The active compounds and chemical composition of RTME were determined by bio-guided isolation and LC-MS/MS, respectively. Compared to the colitis group, the rats treated with RTME displayed significantly lowered macroscopic scores and colon wet weights (p < 0.001). These effects were confirmed biochemically by a decrease in colonic MPO activity (p < 0.001), MDA levels (p < 0.001), and an increase in GSH levels (p < 0.001). Kaempferol-3-O-β-d-glucuronide (RT1) and quercetin-3-O-β-d-glucuronide (RT2) were found to be the major compounds of RTME, as evidenced by in vitro anti-inflammatory and antioxidant activity-guided isolation. Their anti-inflammatory/antioxidant activities were also predicted by docking simulations. Additionally, quinic acid, 5-caffeoylquinic acid, quercetin pentoside, quercetin glucoside, quercetin-3-O-β-d-glucuronide, kaempferol-3-O-β-d-glucuronide, and kaempferol rutinoside were identified in RTME via using LC-MS/MS. RT2, along with other compounds, may be responsible for the observed protective action of RTME against colitis. This study represents the first report on the beneficial effects of RTME in an experimental model of colitis and highlights the potential future use of RTME as a natural alternative to alleviate colitis.

Kaempferol 3-O-(2 G-glucosylrutinoside)-7-O-glucoside isolated from the flowers of Hosta plantaginea exerts anti-inflammatory activity via suppression of NF-κB, MAPKs and Akt pathways in RAW 264.7 cells. Biomed Pharmacother 2022; 153:113295. [PMID: 35724507 DOI: 10.1016/j.biopha.2022.113295] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Revised: 05/25/2022] [Accepted: 06/10/2022] [Indexed: 11/23/2022] Open
Abstract
Kaempferol 3-O-(2G-glucosylrutinoside)-7-O-glucoside (KGG) has isolated from Hosta plantaginea flowers and possessed an inhibitory effect on cyclooxygenase 2 (COX-2), could be effective in inhibiting inflammation. However, the anti-inflammatory activity and mechanism of KGG remain unknown. In this study, for the first time, the anti-inflammatory effect of KGG and its potential molecular mechanisms were explored in cells. KGG had no cytotoxicity at concentrations of 1.25, 2.5, 5, 10, 20, and 40 μM by Cell Counting kit-8 assay in RAW 264.7 cells. Besides, KGG concentration-dependently (1.25, 2.5, and 5 μM) inhibited secretions of nitric oxide (NO), prostaglandin E2 (PGE2), tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β), and IL-6 in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. Western blot showed that the phosphorylation of nuclear factor kappa-B (NF-κB) p65, inhibitor of NF-κB (IκB), p38 MAPK, c-Jun N-terminal kinases (JNK), extracellular signal-regulated kinase (Erk), and protein kinase B (Akt), together with inducible nitric oxide synthase (iNOS) and COX-2 were significantly attenuated by KGG (1.25, 2.5, and 5 μM) in a concentration-dependent relationship. Meanwhile, KGG remarkably enhanced the protein expression of IκB. Taken together, KGG may be one of bioactive phytochemicals from H. plantaginea flowers, and be an anti-inflammatory agent via inhibiting NF-κB, mitogen-activated protein kinases (MAPKs), and Akt signaling pathways.

Abstract
The dried leaves and rhizomes of Alpinia zerumbet have been traditionally used as food and medicine. Anti-inflammatory activity-guided phytochemical investigation into the rhizomes of A. zerumbet led to the isolation of 17 compounds including 10 neolignans (1-10, 1a, 1b, 2a, 2b, 3a, 3b, 4, and 5 are new compounds) and seven diarylheptanoids (11-17) in which 1-3 were three pairs of enantiomers. 4 was only one enantiomer and 5 was a racemic mixture. Compounds 1a, 1b, 2a, and 2b incorporated an 8',9'-dinorneolignan skeleton, which was rare in the lignan family. The planar structures of these compounds were elucidated by extensive analyses of spectroscopic data. The relative and absolute configurations were determined by the time-dependent density functional theory (TDDFT)-based electronic circular dichroism (ECD) calculation method. The 95% ethanol extract and ethyl acetate extract of A. zerumbet were found to show anti-inflammatory activity against croton oil-induced ear edema in mice with inhibition rates of 20.0 and 47.6% at a dose of 80 mg/kg, respectively. Bioassays showed that compounds 1a, 1b, 2a, 2b, and 12 moderately inhibited nitric oxide (NO) production in lipopolysaccharide (LPS)-induced RAW264.7 cells with IC50 values of 3.62, 7.63, 6.51, 5.60, and 8.33 μM, respectively.

Abstract
Medicinal plants belonging to the genus Ardisia are traditionally used to cure various human diseases including inflammation and cancer. This study aimed to purify and characterize cytotoxic and anti-inflammatory compounds from Ardisia sieboldii leaves. Bioassay-guided chromatographic analyses yielded three compounds, 2-methyl-5-(8Z-heptadecenyl) resorcinol (1), 5-(8Z-heptadecenyl) resorcinol (2), and ardisiaquinone A (3), whereas liquid chromatography-electrospray ionisation-mass spectrometry chemical profiling revealed the presence of diverse resorcinol and alkylbenzoquinone derivatives in cytotoxic 70% methanol extracts. Chemical structures of 1-3 were confirmed by spectroscopic methods including 1H NMR (nuclear magnetic resonance), 13C NMR, and electrospray ionisation-mass spectrometry. Compounds 1 and 2 were purified from A. sieboldii for the first time, and all three compounds showed cytotoxicity against a panel of cancer cell lines and brine shrimps in a dose-response manner. Among them, compound 2 exhibited the highest cytotoxicity on cancer cells (IC50 values of 8.8-25.7 μM) as well as on brine shrimps (IC50 value of 5.1 μM). Compounds 1-3 exhibited anti-inflammatory effects through inhibiting protein denaturation (IC50 values of 5.8-9.6 μM), cyclooxygenase-2 activity (IC50 values of 34.5-60.1 μM), and nitrite formation in RAW 264.7 cells. Cytotoxic and anti-inflammatory activities of 1-3 demonstrated in this study deserve further investigation for considering their suitability as candidates or leads to develop anticancer and anti-inflammatory drugs.
