Abstract
As part of our research group’s continuous efforts to find alternative treatments for cancer, the aqueous ethanol extract of Sesbania sesban L. Merr. (SS, Egyptian riverhemp) demonstrated an antileukemic activity against K562 cell line. Bioguided fractionation of SS leaves hydroethanolic extract resulted in the isolation of one new compound (33) named as hederatriol 3-O-β-D-glucuronic acid methyl ester as well as 34 known compounds. Seven compounds ((34), (22), (20), (24), (21), (19), and (35)) showed high antiproliferative effects (IC50 = 22.3, 30.8, 31.3, 33.7, 36.6, 37.5, and 41.5 μM, respectively), while four compounds ((32), (5), (29), and (1)) showed milder activities (IC50 = 56.4, 67.6, 83.3, and 112.3 μM, respectively). A mechanistic study was further carried out on a molecular genetics level against several transcription factors signaling pathways that are incorporated in the incidence of cancer. The results showed that compounds (22) and (21) demonstrated a specific inhibition of Wnt pathway (IC50 = 3.8 and 4.6 μM, respectively), while compound (22) showed a specific inhibition of Smad pathway (IC50 = 3.8 μM). Compound (34) strongly altered the signaling of Smad and E2F pathways (IC50 = 5 μM). The bioactive metabolites were further investigated in silico by docking against several targets related to K562 cell line. The results showed that compounds (22) and (34) exhibited a strong binding affinity towards topoisomerase (docking score = −7.81 and −9.30 Kcal/Mole, respectively). Compounds (22) and (34) demonstrated a strong binding affinity towards EGFR-tyrosine kinase (docking score = −7.12 and −7.35 Kcal/Mole, respectively). Moreover, compound (34) showed a strong binding affinity towards Abl kinase (docking score = −7.05 Kcal/Mole).

Abstract
Tormentic acid ester glucosides derivatives (1, 2 and 4), 3-oxoursane ester glycoside (3) and 11-methoxy-ursane ester glycosides (5, 6) as six new triterpenoids, along with catechin were isolated from the ethyl acetate fraction of Potentilla reptans root (Et) methanolic extract. The structures of the compounds were elucidated by 1D, 2D NMR, IR and MS spectroscopy. Additionally, isolated triterpenoid compounds (1-6) and catechin were evaluated for their cardioprotective effects via glycogen synthase kinase 3β (GSK-3β) and glucocorticoid regulated kinase-1 (SGK1) protein kinase inhibition by Molecular Docking. Compound 1 and catechin (compound 7) exhibited significant inhibitory effects against GSK-3β and SGK1 protein kinases with a binding energy value -9.1 and -8.8 kcal/mol, respectively. Hence, Et can be a suitable natural candidate to protect cardiomyocytes injury.

Abstract
Chromatographic separation of the extracts of the Australian rainforest plant Ternstroemia cherryi led to the isolation of five undescribed barrigenol-like triterpenoids, ternstroenols A - E, from the fruits and three known ones from the leaves. Ternstroenols A - E represent a new form of structural diversity, being the first in its kind to incorporate a trans- 2, 4, 6- decatrienoyl moiety at C-22. The structures of the ternstroenols were assigned by detailed spectroscopic analysis, degradation and chemical derivatization. All compounds exhibited potent anti-inflammatory activity in LPS and IFN- γ activated RAW 264.7 macrophages, with IC50 values as low as 0.7 μM. Despite the remarkable potency, high levels of unwanted cell growth inhibition was also observed, which prompted their cytotoxic evaluation in U87/U251 human glioblastoma cell lines.

Abstract
CONTEXT Ternstroemia gymnanthera Sprague (Theaceae) possesses various known pharmacological properties. However, its anti-inflammatory activity has not been reported. OBJECTIVE The anti-inflammatory activity of Ternstroemia gymnanthera stem bark aqueous extract (TGSBE) was evaluated using LPS-stimulated RAW264.7 macrophages. MATERIALS AND METHODS Cytotoxicity was assessed by MTT assay after 24 h with TGSBE (25-200 μg/mL). Further testing used TGSBE at 100 and 200 μg/mL. Griess and ELISA methods after 24 h with TGSBE determined NO and cytokine levels, respectively; then, mRNA levels (iNOS & cytokines) were analyzed by Quantitative-PCR after 12 h. NF-κB and MAPK were assessed by immunoblotting after TGSBE treatment for 12 h, followed by LPS for 30 min. Immunofluorescence assay was also performed for NF-κB. ROS and MMP, after 12 h with TGSBE, were determined by flow cytometry. The antioxidant potential of TGSBE was analyzed by ABTS assay. The Folin-Ciocalteu method determined the total phenolic content of TGSBE. LPS concentration was 0.5 μg/mL. RESULTS TGSBE at 200 μg/mL showed about 96.2% viability while suppressing the production of NO (88.99%), TNFα (24.38%), IL-6 (61.70%) and IL-1β (55.12%) and gene expression by 67.88, 45.24, 65.84, and 70.48%, respectively. TGSBE decreased ROS (79.26%) and improved MMP (48.01%); it inhibited translocation of NF-κB and MAPK activation. Radical scavenging activity was 50% at 402.17 μg/mL (ascorbic acid standard: 88.8 μg/mL). Total phenolic content was 240.9 mg GAE/g. DISCUSSION AND CONCLUSION TGSBE suppresses the inflammatory response by inhibiting the NF-κB and MAPK cascades exhibiting therapeutic potential to treat inflammatory diseases associated with increased activation of macrophages.

Abstract
A new triterpenoid, 3-oxo-12β-hydroxy-oleanan-28,13β-olide (1), and six known triterpenoids 2–7 were isolated from the root bark of Ekebergia capensis, an African medicinal plant. A limonoid 8 and two glycoflavonoids 9–10 were found in its leaves. The metabolites were identified by NMR and MS analyses, and their cytotoxicity was evaluated against the mammalian African monkey kidney (vero), mouse breast cancer (4T1), human larynx carcinoma (HEp2) and human breast cancer (MDA-MB-231) cell lines. Out of the isolates, oleanonic acid (2) showed the highest cytotoxicity, i.e., IC50’s of 1.4 and 13.3 µM against the HEp2 and 4T1 cells, respectively. Motivated by the higher cytotoxicity of the crude bark extract as compared to the isolates, the interactions of oleanonic acid (2) with five triterpenoids 3–7 were evaluated on vero cells. In an antiplasmodial assay, seven of the metabolites were observed to possess moderate activity against the D6 and W2 strains of P. falciparum (IC50 27.1–97.1 µM), however with a low selectivity index (IC50(vero)/IC50(P. falciparum-D6) < 10). The observed moderate antiplasmodial activity may be due to general cytotoxicity of the isolated triterpenoids.

Abstract
Three new ursane- and four new oleanane- type triterpenoids 1-7 were isolated, along with six known compounds 8-13, from the methanolic extract of Microtropis fokienensis. All structures were elucidated by mass and NMR spectroscopic methods. The isolates 4-10 and known compounds 14-17 that were previously isolated from this material were evaluated for anti-inflammatory activity based on effects against superoxide anion generation and elastase release by neutrophils in response to fMLP/CB. 11α,30-Dihydroxy-2,3-seco-olean-12-en-2,3-dioic anhydride (7) was the first triterpene anhydride from the genus of Microtropis to have the ring A expanded to a seven-membered ring; it showed significant anti-inflammatory activity against superoxide anion generation and elastase release. Unexpectedly, 30-hydroxy-2,3-seco-lup-20(29)-ene-2,3-dioic acid (17) showed the best effect against superoxide anion generation and elastase release with IC50 values of 0.06±0.01 and 1.03±0.35 µg/mL, respectively. Compound 17 had a dioic acid function, and compound 7 had an anhydride function modification in ring A; both showed promising activity in the target assays.

Abstract
CONTEXT Fruits of Ternstroemia sylvatica Schltdl. and Cham. (Theaceae) are used in Mexican traditional medicine to alleviate anxiety, sleep disorders and seizures; however, the active principles have not been identified. OBJECTIVE To identify the neuroactive principles of T. sylvatica fruits using neuropharmacological tests on mice. MATERIALS AND METHODS The methanol and aqueous extracts of pericarp or seeds of T. sylvatica fruits were intraperitoneally administered (1-562 mg/kg, single doses) to mice. The exploratory cylinder, hole board, open field, Rota-rod and sodium pentobarbital-induced hypnosis tests were used to evaluate the CNS depressant effect after 30 min single administration of extracts. From aqueous seeds extract, triterpene glycoside 28-O-[β-l-6-rhamnopyranosyl]-R1-barrigenol was isolated an active compound. RESULTS Crude extracts of T. sylvatica fruits, separated from seed and pericarp, showed sedative effect in mice. The aqueous (ED50 = 4.9 ± 0.8 mg/kg) seed extracts is the most active among them. This extract also decrease locomotor activity and disrupt motor coordination of mice. This extract was also the most toxic extract (LD50 = 5.0 ± 1.4 mg/kg; i.p.). The triterpene glycoside 28-O-[β-l-6-rhamnopyranosyl]-R1-barrigenol was identified in this extract as one of the active sedative compounds (ED50 = 0.12 ± 0.01 mg/kg) also with toxic effect (LD50 = 1.11 ± 0.23 mg/kg). CONCLUSION The results suggest that T. sylvatica fruits has toxic activity rather than CNS depressant activity in mice and that this effect might be related to the presence of 28-O-[β-l-6-rhamnopyranosyl]-R1-barrigenol, one of the active principles of T. sylvatica fruits with sedative and toxic effect.

Abstract
The fruit of Chaenomeles speciosa is a traditional Chinese medicine used for the treatment of dyspepsia and various inflammatory diseases. In the present study, we evaluated the potential radical scavenging capacity, and activity against nitrous oxide, inflammatory cytokines production and neuramindase (NA) of its isolates. The results showed that 3,4-dihydroxybenzoic acid (1) displayed higher inhibitory activities on DPPH and NA with IC50 values of 1.02 μg/mL and 1.27 μg/mL respectively, and quercetin (2) also showed significant inhibitory action on DPPH and NA, with IC50 values of 3.82 μg/mL and 1.90 μg/mL. Compounds 1, 2 and methyl 3-hydroxybutanedioic ester (3) could inhibit the production of TNF-α by 22.73%, 33.14% and 37.19% at 5 μg/mL (P < 0.05) compared with the control. In addition, compound 2 was found to be active on the release of IL-6 in RAW264.7 macrophage cells, with an inhibitory rate of 39.79% (P < 0.05). The anti-inflammatory effect of compound 3 is disclosed for the first time in this study. Avian influenza is usually accompanied by virus invasion followed by the occurrence of oxidative stress and serious inflammation, so the multiple effects of the isolates may play a cocktail-like role in the treatment of avian influenza, and C. speciosa components, especially quercetin, might be a potent source for anti-viral and anti-inflammatory agents.

Balderas JL, Reza V, Ugalde M, Guzmán L, Serrano MI, Aguilar A, Navarrete A. Pharmacodynamic interaction of the sedative effects of Ternstroemia pringlei (Rose) Standl. with six central nervous system depressant drugs in mice. JOURNAL OF ETHNOPHARMACOLOGY 2008; 119:47-52. [PMID: 18582555 DOI: 10.1016/j.jep.2008.05.035] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/03/2008] [Revised: 05/27/2008] [Accepted: 05/28/2008] [Indexed: 05/26/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The decoction of dried fruits of Ternstroemia pringlei (Rose) Standl. (Theaceae), commonly known as "Flor de Tila", is used in the Mexican traditional medicine to diminish insomnia and fear. AIM OF THE STUDY To examine the sedative effects of the dried fruits of Ternstroemia pringlei and investigate a possible synergistic pharmacodynamic interaction between the sedative effect of aqueous extract of this plant and six central nervous system (CNS) depressant drugs. MATERIALS AND METHODS The sedative effect was performed using the exploratory cylinder test in ICR mice. The extracts and drugs were intraperitoneally administered 30 min before testing in different doses, with exception of ethanol and buspirone which were administered 5 and 20 min before testing, respectively. An isobolographic analysis was used to characterize the interaction between Ternstroemia pringlei extract and six CNS depressant drugs. RESULTS The intraperitoneal administration of the hexane, dichloromethane, methanol and aqueous extracts of Ternstroemia pringlei showed a dose-dependent sedative effect. Ternstroemia pringlei aqueous extract combined with buspirone, diazepam, diphenhydramine, haloperidol or pentobarbital exerted a super-additive (synergistic) sedative interaction. Whereas the combination Ternstroemia pringlei extract plus ethanol resulted in a sub-additive (attenuate) sedative interaction. CONCLUSIONS These findings are in agreement with the traditional use of Ternstroemia pringlei in the treatment of insomnia, however it is a plant that interacts in a complex form with CNS depressant drugs. It may represent an advertence on the use of this plant concomitantly with other neuroactive drugs.

Abstract
Investigation on the EtOH extract of the fruits of Chaenomeles speciosa led to the isolation of a new triterpene acid bearing an unusual hydroperoxyl substitute group at C-11, speciosaperoxide (1), along with six known triterpenoids, 3beta-acetoxyurs-11-en-13beta,28-olide (2), 3-O-acetyl ursolic acid (3), oleanolic acid (4), ursolic acid (5), masilinic acid (6), and tormentic acid (7), and three known norsesquiterpenoids, roseoside (8), vomifoliol (9) and (6S,7E,9R)-6,9-dihydroxy-4,7-megastigmadien-3-one 9-O-[beta-d-xylopyranosyl (1 --> 6)-glucopyranoside] (10). Their structures were elucidated on the basis of spectroscopic data and comparison with reference data. Besides compound 1, compounds 2, 8-10 were obtained from this genus for the first time. None of these compounds exhibited inhibitory activity against T-and B-lymphocyte proliferation.

Abstract
Five new triterpenoids, microfokienoxanes A-D (1-4) and 3beta,28-dihydroxy-11alpha-methoxyurs-12-ene (5), were isolated and identified from the leaves of Microtropis fokienensis, along with nine known compounds. The structures of the new compounds were elucidated by spectroscopic methods. The compounds obtained in this investigation were evaluated against a small panel of human cancer cell lines for cytotoxicity. Only compounds 3 and 5 exhibited cytotoxicity (IC50 < or = 5 microg/mL) for one or more cell lines.

Abstract
Three clerodane diterpenoids, premnones A-C (1-3), were isolated from a chloroform-soluble fraction of Premna tomentosa along with four known flavonoids and three known triterpenoids. Among these isolates, premnones A-C exhibited cytotoxic activity when evaluated against a small panel of tumor cell lines. However, premnone A was found to be inactive when evaluated in a follow-up in vivo hollow fiber assay at the highest dose tested (50mg/kg), using LNCaP, Lu1, and MCF-7 cells.

Abstract
The metabolic profile of secondary products in calli and cell suspension cultures of Camptotheca acuminata Decaisne was investigated and compared to that of the leaves and roots taken from the plant. Neither in vitro system produced the anticancer quinoline alkaloid camptothecin (CPT); they accumulated discrete quantities of polyhydroxylated triterpenoids, different from those found in the plant organs, and ellagic acid derivatives. Nine ellagic acid derivatives (1a-1d and 2a-2e) and eight triterpenoid acids (3a-3e and 4a-4c) were isolated and characterised. All the identified triterpenes were related to ursane- or oleanane-type skeletons and their concentrations rose to 4.5% in suspended cells.
