Abstract
Anthemis tricolor is an endemic species of Cyprus, and there is very limited information on its chemistry and pharmacological activities. The study aims to identify the in-vitro cytotoxic and acetylcholinesterase activities of Anthemis tricolor. The compounds responsible for the activities were also identified. Potent extracts of A. tricolor were subjected to preparative isolation and spectral structure determination studies. The chloroform extract contained many components, and due to the small quantity of extract available, enough pure compound(s) cannot be obtained for structure determination studies, though the n-hexane extract afforded two known compounds, totarol (1) and taraxasterol (2). The structures of the compounds (1 and 2) were determined by 1 H and 13 C NMR experiments. The pure compounds were also tested for their acetylcholinesterase inhibitory properties. For compound 1, the IC50 value was found to be 87.88 μg/mL. However, no inhibition was seen for 2. Anthemis tricolor was established to be a valuable source of pharmacologically active compounds and requires further studies.

Abstract
Tatridin A (TatA) is a germacrane sesquiterpenoid containing one E-double bond and one Z-double bond in its 10-membered ring, which is fused to a 3-methylene-dihydrofuran-2-one moiety. Tatridin A bioactivity has been poorly investigated despite its interesting chemical structure. Here, a functional proteomic platform was adapted to disclose its most reliable targets in leukemia monocytic cells, and phosphoglycerate kinases were recognized as the most affine enzymes. Through a combination of limited proteolysis and molecular docking, it has been discovered that tatridin A interacts with the active domains of phosphoglycerate kinase 1, altering its hinge region, and it can be accountable for tatridin A inhibition potency on enzyme activity. A more detailed tatridin A biological profile showed that it is also fully active against gastric cancer cells, downregulating the mRNA levels of chemokine receptor 4 and β-catenin and inhibiting the invasiveness of living KATO III cells as a direct consequence of phosphoglycerate kinase 1 antagonism.

Abstract
Narjatamolide (1), an unusual homoguaiane sesquiterpene lactone, was isolated from the roots and rhizomes of Nardostachys jatamansi DC. It represents the new carbon skeleton of a homoguaiane sesquiterpenoid possessing an additional acetate unit spiro-fused with C-4 and C-15 to form a cyclopropane ring. The structure of 1 was elucidated by extensive spectroscopic analyses, and the absolute configuration was confirmed by the electronic circular dichroism (ECD) calculations and X-ray single-crystal diffraction analysis. Compound 1 showed antiproliferative effects against BEL-7402 cell lines with an IC50 value of 5.67 ± 1.43 μM, and the mechanism study showed that 1 induces cell cycle of BEL-7402 cell lines arrest at G2/M phase.

Abstract
A selected series of racemic α-methylene-γ-butyrolactones (AMGBL) synthesized via allylboration or allylindation reactions were screened against methicillin-resistant Staphylococcus aureus (MRSA) USA300. Unlike natural AMGBLs, such as parthenolide, synthetic analogs bearing aryl moieties at the β- and γ-positions are potent against MRSA. The most potent molecules were comparable to vancomycin and linezolid, the drugs of the last resort for MRSA infections, in their effectiveness with minimum inhibitory concentrations (MICs) ranging from 3.0 to 5.2 μM. These lactones also exhibited potent antibacterial activity against other clinically important multidrug-resistant Gram-positive bacteria (except enterococci), while also showing high tolerability to mammalian cells. Several of these molecules surpassed vancomycin in their rapid killing of the high MRSA inoculum (2 h vs 12 h) in a standard time-kill kinetics assay, with compounds 1l and 1m significantly reducing the intracellular burden of MRSA by about 98-99%, at low concentrations. Additionally, the compounds surpassed vancomycin in inhibiting staphylococcal protease production, indicating that synthetic methylene lactones warrant further investigations as promising anti-MRSA candidates.

Abstract
Anthemis austriaca Jacq. flowers are traditionally used to alleviate abdominal pain, hemorrhoids, ovary diseases and pneumonia. This study aimed to investigate the effects of A. austriaca flowers, which are frequently used in gynecological disorders, on the rat endometriosis model. The rat endometriosis model was used to evaluate the potential activity of the plant in endometriosis. The dried plant material was extracted with n-hexane, ethyl acetate (EtOAc), and methanol (MeOH), successively. The obtained extracts from A. austriaca flowers were applied to the rats. The adhesion scores, endometrial foci areas, and cytokine levels of the peritoneal fluids were measured on surgical induction of endometriosis in rats. The adhesion scores, endometriotic volume, and cytokine levels of the peritoneal fluids were reduced in the EtOAc, MeOH, and buserelin acetate-treated (reference) groups. The MeOH extract reduced the adhesion scores and endometrial foci areas from 3.1 to 1.1 (p < 0.01) and from 86.4 to 40.5 (p < 0.01), respectively and also the MeOH extract reduced tumor necrosis factor (TNF)-α, vascular endothelial growth factor (VEGF), and interleukin (IL)-6 levels of the peritoneal fluids from 13.7 to 3.8 (p < 0.01), from 28.4 to 16.3 (p < 0.05) and from 50.2 to 24.3 (p < 0.01), respectively. Therefore, isolation studies were conducted on the EtOAc and MeOH extracts. After the MeOH extract was fractionated using RP-18 column, the obtained subfractions were evaluated again on the endometriosis rat model. Subfractions A and C of the MeOH extract displayed statistically significant activity on the endometriosis rat model. Phytochemical investigation resulted in the isolation of 4-β-D-glucopyranosyloxy-6-methyl-2H-pyran-2-one (1) from Fr. A and quercetin (2), apigenin-7-O-(3″-O-acetyl)-β-D-glucopyranoside (3), apigenin-7-O-(6″-O-acetyl)-β-D-glucopyranoside (4), apigenin-7-O-β-D-glucopyranoside (5), quercetin-7-O-β-D-glucopyranoside (6) from Fr. C. Moreover, β-sitosterol-3-O-β-D-glucopyranoside (7) was isolated from the EtOAc extract. As a conclusion, the MeOH extract obtained from A. austriaca flowers contributed to the regression of endometriosis. In addition, flavonoids and sterols of the plant were detected as the possible compounds responsible for the activity.

Abstract
Context The genus Anthemis L. (Asteraceae) comprises about 195 species which are widely used in the pharmaceutical, cosmetic and food industries. Objective Anthemis mirheydari Iranshar, an endemic plant from Iran, was investigated for its cytotoxic properties and chemical constituents. Materials and methods The whole parts of the plant (320 g) were extracted by dichloromethane and methanol for four days, successively. The cytotoxic activity of both dichloromethane and methanol extracts were assayed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide colorimetric methods against three human cancer cell lines including LS180, MCF-7 and MOLT-4. Different concentrations (10-100 μg/mL) of the plant extracts were tested to obtain IC50 values. The dichloromethane extract of A. mirheydari was subjected to silica gel-column and thin layer chromatography for purification of its chemical constituents and the isolated compounds were further tested against MOLT-4 cells. The structures of the pure compounds were elucidated using different spectral data including nuclear magnetic resonance and electron impact mass spectra. Results The IC50 values of the dichloromethane extract were 30.8 ± 6.7, 25.2 ± 6.5 and 8.6 ± 1.1 μg/mL (means ± standard error) for the above-mentioned cell lines, respectively. Two triterpenoids, taraxasterol (1) and pseudotaraxasterol (2), one sterol, β-sitosterol (3) and one coumarin, 7-methoxycoumarin (4) were isolated from the extract. The IC50 of the mixture of compounds 1 and 2 as well as compounds 3 and 4 were higher (>100 μM) than that reported for the dichloromethane extract against MOLT-4 cells. Conclusion The dichloromethane extract was the most active one among the tested material.

Abstract
The chemical composition of the essential oils and aromatic waters isolated from six Italian Anthemis maritima populations was determined by GC-FID and GC/MS analyses. In total, 122 and 100 chemical compounds were identified in the essential oils and the aromatic waters, respectively. The main compound classes represented in the oils were monoterpene hydrocarbons, oxygenated monoterpenes, sesquiterpene hydrocarbons, oxygenated sesquiterpenes, and terpene esters. Multivariate chemometric techniques such as cluster analysis (CA) and principal coordinate analysis (PCO) were used to classify the samples according to the geographical origin. Statistical analysis allowed the attribution of the analyzed populations to different chemotype groups.

Abstract
Sesquiterpene lactones (STLs) present a wide range of biological activities, mostly based on their alkylating capabilities, which underlie their therapeutic potential. These compounds are the active constituents of a variety of plants, frequently used as herbal remedies. STLs such as artemisinin and its derivatives are in use as first-line antimalarials while others, such as parthenolide, have recently reached cancer clinical trials. However, the toxicological profile of these compounds must be thoroughly characterized, since the same properties that make STL useful medicines can also cause severe toxicity. STL-containing plants have long been known to induce a contact dermatitis in exposed farm workers, and also to cause several toxic syndromes in farm animals. More recently, concerns are been raised regarding the genotoxic potential of these compounds and the embryotoxicity of artemisinins. A growing number of STLs are being reported to be mutagenic in different in vitro and in vivo assays. As yet no systematic studies have been published, but the genotoxicity of STLs seems to depend not so much on direct DNA alkylation as on oxidative DNA damage and other partially elucidated mechanisms. As the medicinal use of these compounds increases, further studies of their toxic potential are needed, especially those focusing on the structural determinants of genotoxicity and embryotoxicity.

Abstract
BACKGROUND Anthemis species have been used for the treatment of gastrointestinal disorders, hemorrhoid, stomachache and inflammatory diseases in Turkish folk medicine. Anthemis wiedemanniana Fisch. And Mey. is an endemic plant used as painkiller, antispasmodic, sedative and for the treatment of urinary inflammations. OBJECTIVE The objective of the present study is to evaluate the anti-inflamatory activity of the extracts of A. wiedemanniana by using in vivo methods. MATERIALS AND METHODS Carrageenan-, PGE2- and serotonin-induced hind paw edema, 12-O-tetradecanoyl-13-acetate (TPA)-induced mouse ear edema and acetic acid-induced increase in capillary permeability models were used for the anti-inflammatory activity assessment. Moreover, the fatty acid composition of A. wiedemanniana was investigated by gas chromatography (GC). RESULTS n-Hexane, diethyl ether and total sesquiterpene lactone extracts exhibited significant inhibition in carrageenan-induced hind paw edema and acetic acid-induced increase in capillary permeability model. n-Hexane and total sesquiterperne lactone extracts showed anti-inflammatory activity in PGE2- and serotonin-induced hind paw edema model. However none of the extracts displayed significant activity in TPA-induced ear edema model in mice. C4:0 (Buthyric acid), C20:0 (Arachidic acid) and C16:1 (Palmitoleik acid) were found to be the major fatty acids in these species. Saturated fatty acids (SFA) were found in higher amounts than monounsaturated fatty acids and polyunsaturated fatty acids. SFAs were determined as 63.17%, UFAs as 20.89% and PuFAs as 15.95%. CONCLUSION This study confirms the traditional usage of A. wiedemanniana for inflammatory diseases.

Two sabina δ-lactones (3 and 4) were obtained in a two-step synthesis from (+)-sabinene (1). The oxidation of (+)-sabinene (1) with potassium permanganate and sodium periodate to (–)-sabina ketone (2) was the first step. In the second step, the ketone obtained was subjected to chemical and microbial Baeyer–Villiger oxidation. Chemical Baeyer–Villiger oxidation of this ketone afforded two δ-lactones 3 and 4 whereas microbial Baeyer–Villiger oxidation afforded only ‘abnormal’ δ-lactone 4. (–)-Sabina ketone was also the starting material for the synthesis of new δ-lactams (7 and 8). They were obtained by Beckmann rearrangement of sabina ketone oximes 5a and 5b. An attempt to separate (–)-sabina ketone oximes 5a and 5b is also presented.

Abstract
Along with compounds from terrestrial microorganisms, the constituents of higher plants have provided a substantial number of the natural product-derived drugs used currently in Western medicine. Interest in the elucidation of new structures of the secondary metabolite constituents of plants has remained high among the natural products community over the first decade of the 21st century, particularly of species that are used in systems of traditional medicine or are utilized as botanical dietary supplements. In this review, progress made in the senior author's laboratory in research work on naturally occurring sweeteners and other taste-modifying substances and on potential anticancer agents from tropical plants will be described.

[PMID: 21060304 PMCID: PMC6259451 DOI: 10.3390/molecules15117985] [Citation(s) in RCA: 226] [Impact Index Per Article: 16.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2010] [Revised: 11/03/2010] [Accepted: 11/04/2010] [Indexed: 12/26/2022] Open
Abstract
Among the wide diversity of naturally occurring phenolic acids, at least 30 hydroxy- and polyhydroxybenzoic acids have been reported in the last 10 years to have biological activities. The chemical structures, natural occurrence throughout the plant, algal, bacterial, fungal and animal kingdoms, and recently described bioactivities of these phenolic and polyphenolic acids are reviewed to illustrate their wide distribution, biological and ecological importance, and potential as new leads for the development of pharmaceutical and agricultural products to improve human health and nutrition.
