Suspect and Target Screening of Natural Toxins in the Ter River Catchment Area in NE Spain and Prioritisation by Their Toxicity

The method is based on a generic solid-phase extraction procedure, using three sorbent phases in two cartridges that are connected in series, hence covering a wide range of polarities, followed by liquid chromatography coupled to high-resolution mass spectrometry. The acquisition was performed in the full-scan and data-dependent modes while working under positive and negative ionisation conditions. This method was applied in order to assess the natural toxins in the Ter River water reservoirs, which are used to produce drinking water for Barcelona city (Spain). The study was carried out during a period of seven months, covering the expected prior, during, and post-peak blooming periods of the natural toxins. Fifty-three (53) compounds were tentatively identified, and nine of these were confirmed and quantified. Phytotoxins were identified as the most frequent group of natural toxins in the water, particularly the alkaloids group. -

The Limitations of DNA Interstrand Cross-link Repair in Escherichia coli by Jessica Michelle Cole A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Biology Thesis Committee: Justin Courcelle, Chair Jeffrey Singer Rahul Raghavan Portland State University 2018 i Abstract DNA interstrand cross-links are a form of genomic damage that cause a block to replication and transcription of DNA in cells and cause lethality if unrepaired. Chemical agents that induce cross-links are particularly effective at inactivating rapidly dividing cells and, because of this, have been used to treat hyperproliferative skin disorders such as psoriasis as well as a variety of cancers. However, evidence for the removal of cross- links from DNA as well as resistance to cross-link-based chemotherapy suggests the existence of a cellular repair mechanism. -

The aim of this study was to investigate the analgesic/antinociceptive and anti-inflammatory activities of the ethanol extracts of C. anisata root (CRE), A. polycarpa stem (ASE) and root barks (AR) in order to provide scientific justification for their use as anti-inflammatory and analgesic agents. Analgesic activity was evaluated using the hot plate and the acetic acid induced writhing assays. The mechanism of antinociception was evaluated by employing pharmacological antagonism assays at the opioid and cholinergic receptors in the hot plate and the writhing assays. -

The Health Benefits of Grapefruit Furanocoumarins1 Yu Wang and Laura Reuss2
FSHN18-8 The Health Benefits of Grapefruit Furanocoumarins1 Yu Wang and Laura Reuss2 Although not recommended for use with certain medica- tions, grapefruits are known for their numerous health benefits. Both these effects come from, in part, natural chemicals called furanocoumarins. Although these biologically active plant compounds, or phytochemicals, are beneficial to overall health, some compounds have been shown to interact with numerous medications, causing adverse effects known as the “grapefruit juice effect.” Furanocoumarins and flavanones are the major compounds responsible in these drug interactions. Several studies have reported that furanocoumarins present in grapefruit affect absorption of some medications by interfering with a cer- tain liver and intestinal enzyme (Guo et al. 2000). However, numerous studies have shown that compounds in citrus fruits, including furanocoumarins, reduce inflammation and stop cancer cells from multiplying. Furthermore, they Figure 1.

Osbeck Bergamot Group (synonym Citrus × bergamia Risso & Poit.), resulting in the bursting of the oil cavities embedded in the flavedo and the release of their contents. It is chemically dominated by monoterpene hydrocarbons (i.e., limonene), but with significant percentages of oxygenated monoterpenes (i.e., linalyl acetate) and of non-volatile oxygen heterocyclic compounds (i.e., bergapten). Keywords: bergamot; citrus; essential oil; production; review 1. Introduction The taxonomy, and consequently the nomenclature, of the genus Citrus, is particularly complicated and has been rapidly changing in recent years (see Table1).

Naturforsch. 59c, 523Ð527 (2004); received December 21, 2003/February 9, 2004 The aim of this work was to study the antiproliferative effect of a tincture from fruits of Angelica archangelica and the active components using the human pancreas cancer cell line PANC-1 as a model. Significant dose-dependent antiproliferative activity was observed in µ the tincture with an EC50 value of 28.6 g/ml. Strong antiproliferative activity resulted from the two most abundant furanocoumarins in the tincture, imperatorin and xanthotoxin. The contribution of terpenes to this activity was insignificant. Imperatorin and xanthotoxin µ µ proved to be highly antiproliferative, with EC50 values of 2.7 g/ml and 3.7 g/ml, respec- tively, equivalent to 10 and 17 µm.

And Citrus Fruits
Journal of the Science of Food and Agriculture J Sci Food Agric 87:2152–2163 (2007) Analysis of furanocoumarins in vegetables (Apiaceae) and citrus fruits (Rutaceae) Radek Peroutka, Veraˇ Schulzova,´ ∗ Petr Botek and Jana Hajslovˇ a´ Institute of Chemical Technology, Department of Food Chemistry and Analysis, Technicka´ 3, 166 28 Prague 6, Czech Republic Abstract: Several alternative approaches applicable for the analysis of furanocoumarins, toxic components occurring in some fruits and vegetables representing both Apiaceae and Rutaceae families, were tested in our study. Limits of detection (LODs) for angelicin, psoralen, bergapten, xanthotoxin, trioxsalen, isopimpinellin, sphondin, pimpinellin and isobergapten obtained by GC/MS (SIM) were in the range 0.01–0.08 µgg−1.Slightly higher LODs (0.02–0.20 µgg−1) were achieved by LC/MS–MS. The latter is the only alternative for analysis of bergamottin (LOD = 0.01 µgg−1) in citrus fruits because this furanocoumarin is unstable under GC conditions. Regardless of the determination step used, the repeatability of the measurements (expressed as RSD) did not exceed 10%. As shown in our study the levels of furanocoumarins in celery, celeriac, parsnip, carrot, lemon and other foods obtained at a retail market varied over a wide range; the highest contents were determined in parsnip, while the levels of these toxins in carrots and citrus pulps were relatively low. 2007 Society of Chemical Industry Keywords: furanocoumarins; GC/MS; LC/MS–MS; fruits; vegetables INTRODUCTION and fruit of some of these, e.g. figs, representing the Furanocoumarins are toxic secondary metabolites that last family, is also used for human consumption.
