University of California Riverside UNIVERSITY OF CALIFORNIA RIVERSIDE Metabolic Profiling of Primary and Secondary Biosynthetic Pathways in Angiosperms: Comparative Metabonomics and Applications of Hyphenated LC-NMR and LC-MS A Dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Chemistry by Kayla Anne Kaiser March 2012 Dissertation Committee: Dr. Cynthia K. Larive, Chairperson Dr. Dallas Rabenstein Dr. Julia Bailey-Serres Copyright by Kayla Anne Kaiser 2012 The Dissertation of Kayla Anne Kaiser is approved: ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ Committee Chairperson University of California, Riverside Acknowledgements I have not walked this road alone, many people supported me along the way, both in person and in memory. My time here at UCR has been absolutely magical. Thanks to the National Science Foundation, I was able to participate in an interdisciplinary graduate training experience (IGERT) which shaped the course of my graduate education from the day I arrived in Riverside. Receiving financial, professional, and moral support from two esteemed principal investigators, Cynthia Larive and Julia Bailey-Serres, is most certainly a once-in-a-lifetime experience and I feel immensely grateful for their effort. I was lucky enough to have mentors that remained actively engaged in my development as a researcher and as a person, who ultimately sent me across the country and around the world to participate in great science, enhancing my graduate training exponentially. Participating IGERT faculty in other departments including Natasha Raikhel, Kathy Borkovich, Linda Walling, Thomas Girke, Thomas Eulgem, Xumei Chen, Shou-wei Ding, Larry Li, Karine Le Roch, Stefano Lonardi, Dimitrios Morikis, Anandasankar Ray, Harley Smith, Patty Springer, Jason Stajich, Zhenbiao Yang, and Hailing Jin have been of more influence than they are aware. Young faculty such as Wenwan Zhong, Ryan Julian, Katherine Larsen, Greg Beran, Angelina Chang, and Richard Hooley have been encouraging and willing to share their expertise and experience with myself and other students in our department. They have shown me a path to joining them as tenure-track faculty, and I am humbled by their belief that I am capable of rising to such a rank. Chris Bardeen, Jason Cheng, Yinsheng iv Wang, Leonard Mueller, Pingyun Feng, Michael Pirrung, Chris Switzer, and Sean Cutler have each influenced my approach to doing science and living life. The balance and tone of our department is set by these dedicated faculty members, who do an excellent job of providing a workplace that is engaging and dynamic as well as world-class. Francisco Zaera, David Bocian, Robert Haddon, Chris Reed, Eric Chronister, and Tom Morton have played a role in my current success and have influenced my current idea of what it means to be a research professor. I would like to especially thank Mike Rettig and Dallas Rabenstein. Teaching for Mike brought me back to the enjoyment of university life and showed me that true commitment to excellence in teaching can appear effortless after many years of practice. Dallas has always offered me perspective beyond what my mind can even comprehend and I consider his contributions to my understanding of NMR and university education to be invaluable. My fellow IGERT trainees Colleen Knoth, Eddie Cao, Michelle Brown, Charles Jang, James Kim, Christiana Merrywell, Jolene Diedrich, Theresa Dinh, Augusta Jamin, Sean Boyle, Anna Charisi, Andrew Defries, Mindy (Rodriguez) Salus, Missy (Smith) Scranton, Ayesha Baig, Patrick Schacht, Moses Tataw, Shang Wu, Rae Yumul, Aaron Devries, Jessica Diaz, Robert Koble, and Yifan Lii have been an important component of the support web that caught me any time I started flying out of control. These people helped me survive the difficulty of forging complementation at the interface of chemistry, engineering, computational sciences and cell biology and have been the wind in my sails without even knowing it. IGERT support staff Carolina Stickley, Ronly Schlenk, and v Matt Collin helped me balance the additional workload with grace. Glenn Hicks has been a quiet yet steadfast mentor throughout my biological/professional development. My chemistry classmates Kim Worsley, Tony Ly, Bryce Davis, Matt Linman, James Wright, Robert Dillon, Julia Zhu, Kelly Theel, Sebastian Jezowski, Shinji Kaneko, Jessy Lemieux, Yingdi Liu, Christen Strollo, Olivia Alley, Candace Guerrero, Derek Chen, Ying Liu, Bruce Ford, Mark Hamza, Emily Spencer, Ben Moore, Ni Li, Samantha Schachermeyer, Jingjing Yao, Ana Gamboa, Angie Garcia, Aaron Moehlig, Sepideh Yaghmaei, Robert Carp, Aholibama Escobar, Thomas Owen, Tiffany Satoorian, have been immensely helpful. Together we weathered the storms and reaped the abundant harvest. My labmates in the Larive research group Bridget Becker and Albert Korir first introduced me to the beauty of NMR and efficient workflows. Kasie Fang and Christiana Merrywell laid the groundwork for my LC-MS and NMR metabolomic experiments, respectively. Stacie Eldridge was a role model and mentor such as I have never had, nor will ever have again. Jennifer Cruz opened my heart, body and mind, as well as my spirit, to new levels of enlightenment. John Limtiaco was my fellow soldier, marching through the Ph.D. process in step with me, making me feel as an equal and sharing the experience with him has been a great treasure. Chris Jones and Daryl Bulloch pushed me to go farther than I thought I was capable of going. In the words of the late John F. Kennedy, “a rising tide lifts all boats.” Without such dedicated and talented labmmates, I would not have achieved as much. Greg Barding is someone who I respect and admire greatly, it has been a real pleasure working with him. Derek Langslay might be an angel, vi not only did I enjoy his temperament and scientific contributions, but also he makes a strong pot of coffee almost every day. Consuelo Beecher is our current protégé and I predict she will have an abundant career. Our undergraduate researchers Thao Nguyen, Fernando Campos, Sarah Gutierrez, Layne Higgins, Archie Taylor, Arpana Vaniya, Nelly Membreno, Bailey Dickey, Erik Velez, John Nguyen, Patrick Salvenson, Amy Morris, Avi Ramkishun, Matt Manighalam, and last but not least, Vishwa Shah breathed life into our days and shared with us the experience of training and mentoring. I am so grateful to have worked with all of you. Visiting professor Szabolcs Béni and his wife Orsyla Molnár contributed their energy and expertise to our lab generously, and I am immensely grateful for their support. A few more words about Cindy: she has the biggest heart of anyone I know. She is absolutely unmatched in her dedication. Working with her has been like climbing Mt. Everest. Just as a mountain never leaves you feeling unsupported, she is rock-solid. By providing formidable challenges, she exhausted and humbled me. She showed me that by refusing to give up on the ascent, breathtaking heights can be reached. That’s how Cindy is. She can do the work of 10 grown men. No tall tales, she is actually that amazing. I also must acknowledge my stunning collaborators in the Center for Plant Cell Biology: Cristina Branco-Price, Angelika Mustroph, Julian M. Peña-Castro, Piyada Juntawong, Takeshi Fukao, Matthew Collin, Erin Brinton, Seung Cho Lee, Reed Sorenson, Rejbana Alam, Maureen Hummel, and Elaine Yeung. They showed me how to cultivate Arabidopsis and maintained good humor while I persistently presented data vii of a physicochemical rather than biological nature. Their suggestions and feedback throughout my time at UCR have been instrumental in developing my understanding of plant physiology, molecular biology, and genetics. The attention and encouragement provided by Julia Bailey-Serres was nourishment for my soul, allowing me to take greater risks in my learning process, knowing that she believed in my potential for success. Finally, a linchpin in my graduate education was my internship experience at the Max Planck Institute for Chemical Ecology in Jena, Thuringia (Germany). NMR and MS group leaders Bernd Schneider and Ales Svatos, respectively, were beyond hospitable and generous in the exchange of ideas and energy. Fellow NMR group members Christian Paetz, Kamel Shaker, Dirk Holscher, Jingjing Fang, Evalgelos Tatsis, Katia Gruner, and Claudia Cervellati must be acknowledged for their contribution to my grasp of natural product studies beyond model and crop systems (Arabidopsis, rice, corn). Phila Raharivelomanana, a visiting professor, freely shared her personal and professional experiences. My friends at the Institute, who welcomed me and integrated me into their program with open arms: Vojta Klusak, Daniel Giddings Vasso, Holger Danner, Andrea Liliana Clavio McCormick, Alexandra Schmidt, Filippo Scialo, Abu Farhan, Guanjun (Cookie) Li, Marko Petek, Filipe Yon, Variluska Fragoso, Hendrik Wunsche, Maja Miloradovic and Arjen van Doorn. Exchanges with these young researchers will undoubtedly form the basis of future collaborations, and I will never forget my 30 th birthday. A few influential artists and musicians who provided me with inspiration and momentum which helped me finish the experiments and writing summarized in this viii dissertation. I hereby acknowledge Beyoncé, Lady Gaga, Rhianna and Shakira for bringing girl power to my ears and helping me keep tempo while pipetting.

E-mail: [email protected] ABSTRACT. Glycoalkaloids are important secondary metabolites accumulated by plants as protection against pathogens. One of them, α-tomatine, is found in high concentrations in green tomato fruits, while in the ripe fruits, its aglycone form, tomatidine, does not present a protective effect, and it is usual to find parasites of tomatoes like Phytomonas serpens in these ripe fruits. To investigate the sensitivity of trypanosomatids to the action of α-tomatine, we used logarithmic growth phase culture of 20 trypanosomatids from insects and plants and Trypanosoma cruzi. The lethal dose 50% (LD50) was determined by mixing 107 cells of the different isolates with α-tomatine at concentrations ranging from 10-3 to 10-8 M for 30 min at room temperature. The same tests performed with the tomatidine as a control showed no detectable toxicity against the same trypanosomatid cultures. The tests involved determination of the percentage (%) survival of the protozoan cultures in a Neubauer chamber using optical microscopy.

  • Chloroform 18.08.2020.Pdf
    Chloroform Chloroform, or trichloromethane, is an organic compound with formula CHCl3. It is a colorless, sweet-smelling, dense liquid that is produced on a large scale as a precursor to PTFE. It is also a precursor to various refrigerants. It is one of the four chloromethanes and a trihalomethane. It is a powerful anesthetic, euphoriant, anxiolytic and sedative when inhaled or ingested. Formula: CHCl₃ IUPAC ID: Trichloromethane Molar mass: 119.38 g/mol Boiling point: 61.2 °C Density: 1.49 g/cm³ Melting point: -63.5 °C The molecule adopts a tetrahedral molecular geometry with C3v symmetry. Chloroform volatilizes readily from soil and surface water and undergoes degradation in air to produce phosgene, dichloromethane, formyl chloride, carbon monoxide, carbon dioxide, and hydrogen chloride. Its half-life in air ranges from 55 to 620 days. Biodegradation in water and soil is slow. Chloroform does not significantly bioaccumulate in aquatic organisms. Production:- In industry production, chloroform is produced by heating a mixture of chlorine and either chloromethane (CH3Cl) or methane (CH4). At 400–500 °C, a free radical halogenation occurs, converting these precursors to progressively more chlorinated compounds: CH4 + Cl2 → CH3Cl + HCl CH3Cl + Cl2 → CH2Cl2 + HCl CH2Cl2 + Cl2 → CHCl3 + HCl Chloroform undergoes further chlorination to yield carbon tetrachloride (CCl4): CHCl3 + Cl2 → CCl4 + HCl The output of this process is a mixture of the four chloromethanes (chloromethane, dichloromethane, chloroform, and carbon tetrachloride), which can then be separated by distillation. Chloroform may also be produced on a small scale via the haloform reaction between acetone and sodium hypochlorite: 3 NaClO + (CH3)2CO → CHCl3 + 2 NaOH + CH3COONa Deuterochloroform[ Deuterated chloroform is an isotopologue of chloroform with a single deuterium atom.

  • Alpha-Tomatine Content in Tomato and Tomato Products Determined By
    J. Agric. Food Chem. 1995, 43, 1507-151 1 1507 a-Tomatine Content in Tomato and Tomato Products Determined by HPLC with Pulsed Amperometric Detection Mendel Friedman* and Carol E. Levin Food Safety and Health Research Unit, Western Regional Research Center, Agricultural Research Service, U.S. Department of Agriculture, 800 Buchanan Street, Albany, California 94710 Tomato plants (Lycopersicon esculentum) synthesize the glycoalkaloid a-tomatine, possibly as a defense against insects and other pests. As part of an effort to improve the safety of plant foods, the usefulness of a new HPLC pulsed amperometric detection (PAD) method for the direct analysis of a-tomatine in different parts of the tomato plant; in store-bought and field-grown, including transgenic, tomatoes; in a variety of commercial and home-processed tomato products; and in eggplant and tomatillos was evaluated. The method was found to be useful for analysis of a variety of products including high-tomatine calyxes, flowers, leaves, roots, and stems of the tomato plant (14-130 mg/100 g of fresh weight), low-tomatine red tomatoes (0.03-0.08 mg/100 g), intermediate- tomatine tomatoes (0.1-0.8 mg/100 g), and high-tomatine fresh and processed green, including pickled and fried, tomatoes (0.9-55 mg/100 g). No experimental difficulties were encountered with extraction and analysis of tomatine in complex foods such as tomato juice, ketchup, salsa, sauce, and sun-dried tomatoes. Microwaving and frying did not significantly affect tomatine levels of tomato foods. The tomatine content of fresh market and transgenic delayed-ripening varieties was not different from the range ordinarily seen in tomato.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. The glycoalkaloid tomatine, derived from the wild tomato, can act as a powerful adjuvant to elicit an antigen-specific cell-mediated immune response to the circumsporozoite (CS) protein, a major pre-erythrocytic stage malaria vaccine candidate antigen. Using a defined MHC-class-I-restricted CS epitope in a Plasmodium berghei rodent model, antigen-specific cytotoxic T lymphocyte activity and IFN-γ secretion ex vivo were both significantly enhanced compared to responses detected from similarly stimulated splenocytes from naive and tomatine-saline-immunized mice. Further, through lymphocyte depletion it is demonstrated that antigen-specific IFN-γ is produced exclusively by the CD8+ T cell subset.

  • Figure 1. Metabolism of Glucoraphanin and Glucobrassicin to Biologically Active Metabolites
    Legend to Figures: Figure 1. Metabolism of glucoraphanin and glucobrassicin to biologically active metabolites. (A) Sulforaphane is released from glucoraphanin by the plant enzyme myrosinase. Red dashed arrow marks the reactive carbon atom subject to glutathione conjugation. (B) Sulforaphane is metabolized via the mercapturic acid pathway into active metabolites. Glutathione-S-transferase (GST) first conjugates a GSH molecule (Glu-Cys-Gly) to the reactive carbon on sulforaphane. Glutamate is then removed by γ- glutamyltranspeptidase (GTP), followed by removal of the glycine residue by cysteinylglycinase (CGase). Cysteine is then acetylated by an acetyltransferase (AT) to sulforaphane-N-acetylcysteine, which is excreted in the urine. (C) Indole-3-carbinol is released from the glucosinolate glucobrassicin by myrosinase and undergoes spontaneous condensation in the acidic environment of the gut. Diindolylmethane (DIM) is the most abundant post-absorption acid condensation product. Acid condensation products can be modified further post-absorption. LTr1: Linear trimer 1.

Sulforaphane (SFN) and I3C/DIM inhibit the Akt signaling axis, a signaling pathway often hyperactive in prostate cancer. Inhibition of this pathway decreases pro-survival signaling by mTOR, Akt, and NFkB. Sulforaphane and I3C/DIM treatment also lead to changes in gene expression (blue arrow) that trigger growth arrest and apoptosis. The expression of proteins controlling the cell cycle (e.g. p21, p27, CDK6) are altered to effect growth arrest, and apoptosis is finally induced through the mitochondrial pathway.

They contain glucosinolates, which are hydrolysed into isothiocyanates that have shown anticarcinogenic properties in animal experiments. To study the bioavailability, kinetics and effects of isothiocyanates from cruciferous vegetables, biomarkers of exposure and for selected beneficial effects were developed and validated. As a biomarker for intake and bioavailability, isothiocyanate mercapturic acids were chemically synthesised as reference compounds and a method for their quantification in urine was developed.

Current study involves the screening and identification of potent inhibitors of the pneumococcal virulence factor pneumolysin. About 100 flavonoids were chosen from scientific literature and docked with pnuemolysin (PDB Id.: 4QQA) using Patch Dockprogram for molecular docking. The results obtained were analysed and the docked structures visualized using LigPlus software.
