  • Biologically Active Molecules from Soybeans
    10 Biologically Active Molecules from Soybeans Michio Kurosu Department of Pharmaceutical Sciences, University of Tennessee Health Science Center USA 1. Introduction Soybeans (Glycine max [L.] Merr.) contain an impressive array of biologically active components. People have been eating soybeans for almost 5,000 years. Unlike most plant foods, soybeans are high in protein. Researchers are interested in both the nutritional value and the potential health benefits of soybeans. Research of the health effects of soyfoods and soybean constituents has been received significant attention to support the health improvements or health risks observed clinically or in vitro experiments. This research includes a wide range of areas, such as cancer, coronary heart disease (cardiovascular disease), osteoporosis, cognitive function (memory related), menopausal symptoms, renal function, and many others. This chapter provides up-to-date coverage on biologically active and related organic molecules isolated from soy and soy products. Their biological activities are briefly summarized. Molecules discussed in this chapter are as follows: isoflavones, phytic acid, soy lipids, soy phytoalexins, soyasaponins, lectins, hemagglutinin, soy toxins, and vitamins. 2. Health benefit of soy or soy products Soy products have been considered as great source of protein for many decades. Japanese, in particular, eat a soy-based diet. Japanese monks eat soy products as their main protein source. They are known to live longer and have lower rates of chronic diseases. Because soybeans contain practically no starch, soybeans are an important part of a diabetic diet. Soybeans are 1) rich in protein (vide supra), calcium, and vitamins, and 2) high in mono- saturated fatty acids. In addition, soybeans contain several biologically interesting phytochemicals as minor components, which scientists are interested in understanding their biological functions.

Received: 19 October 2010; in revised form: 3 November 2010 / Accepted: 4 November 2010 / Published: 8 November 2010 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. Keywords: polyphenols; phenolic acids; hydroxybenzoic acids; natural occurrence; bioactivities 1. Introduction Phenolic compounds exist in most plant tissues as secondary metabolites, i.e. they are not essential for growth, development or reproduction but may play roles as antioxidants and in interactions between the plant and its biological environment. Phenolics are also important components of the human diet due to their potential antioxidant activity [1], their capacity to diminish oxidative stress- induced tissue damage resulted from chronic diseases [2], and their potentially important properties such as anticancer activities [3-5].

  • Method Development and Validation of Vitamin D2 and Vitamin D3 Using Mass Spectrometry
    Method Development and Validation of Vitamin D2 and Vitamin D3 Using Mass Spectrometry Devon Victoria Riley A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science University of Washington 2016 Committee: Andrew Hoofnagle Geoffrey Baird Dina Greene Program Authorized to Offer Degree: Laboratory Medicine ©Copyright 2016 Devon V. Riley ii University of Washington Abstract Method Development and Validation of Vitamin D2 and Vitamin D3 Using Mass Spectrometry Devon V. Riley Chair of the Supervisory Committee: Associate Professor Andrew Hoofnagle, MD, PhD Vitamin D has long been known to maintain bone health by regulating calcium and phosphorous homeostasis. In recent years, scientists have discovered additional physiological roles for vitamin D. The complex interaction between the active vitamin D hormone and its metabolic precursors continues to be a rich area of research. Fundamental to this research is the availability of accurate and precise assays. Few published assays for vitamins D2 and D3 have contained sufficient details on method validation or performance characteristics. The liquid chromatography-tandem mass spectrometry (LC-MS/MS) assay developed for this thesis has undergone a rigorous validation and proven to yield a sensitive and specific method that exceeds the capabilities of all previously published methods. Developing and validating a novel assay is often complicated by the lack of established acceptability standards. This thesis explores this challenge, specifically for establishing meaningful interpretations and qualification standards of the lower limit of the measuring interval. Altogether, future research focused on vitamins D2, D3 and the Vitamin D pathway can benefit from this robust LC-MS/MS assay and the associated quality parameters outlined in this thesis.

  • Anti-Carcinogenic Glucosinolates in Cruciferous Vegetables and Their Antagonistic Effects on Prevention of Cancers
    molecules Review Anti-Carcinogenic Glucosinolates in Cruciferous Vegetables and Their Antagonistic Effects on Prevention of Cancers Prabhakaran Soundararajan and Jung Sun Kim * Genomics Division, Department of Agricultural Bio-Resources, National Institute of Agricultural Sciences, Rural Development Administration, Wansan-gu, Jeonju 54874, Korea; [email protected] * Correspondence: [email protected] Academic Editor: Gautam Sethi Received: 15 October 2018; Accepted: 13 November 2018; Published: 15 November 2018 Abstract: Glucosinolates (GSL) are naturally occurring β-D-thioglucosides found across the cruciferous vegetables. Core structure formation and side-chain modifications lead to the synthesis of more than 200 types of GSLs in Brassicaceae. Isothiocyanates (ITCs) are chemoprotectives produced as the hydrolyzed product of GSLs by enzyme myrosinase. Benzyl isothiocyanate (BITC), phenethyl isothiocyanate (PEITC) and sulforaphane ([1-isothioyanato-4-(methyl-sulfinyl) butane], SFN) are potential ITCs with efficient therapeutic properties. Beneficial role of BITC, PEITC and SFN was widely studied against various cancers such as breast, brain, blood, bone, colon, gastric, liver, lung, oral, pancreatic, prostate and so forth. Nuclear factor-erythroid 2-related factor-2 (Nrf2) is a key transcription factor limits the tumor progression. Induction of ARE (antioxidant responsive element) and ROS (reactive oxygen species) mediated pathway by Nrf2 controls the activity of nuclear factor-kappaB (NF-κB). NF-κB has a double edged role in the immune system. NF-κB induced during inflammatory is essential for an acute immune process. Meanwhile, hyper activation of NF-κB transcription factors was witnessed in the tumor cells. Antagonistic activity of BITC, PEITC and SFN against cancer was related with the direct/indirect interaction with Nrf2 and NF-κB protein.

Synthesis was performed in a “one-pot”, two-step procedure, in the presence of organic base (Et3N, DBU or NMM), and carbon disulfide via dithiocarbamates, with 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4- methylmorpholinium toluene-4-sulfonate (DMT/NMM/TsO−) as a desulfurization reagent. For the synthesis of aliphatic and aromatic isothiocyanates, reactions were carried out in a microwave reactor, and selected alkyl isothiocyanates were also synthesized in aqueous medium with high yields (72–96%). Isothiocyanate derivatives of L- and D-amino acid methyl esters were synthesized, under conditions without microwave radiation assistance, with low racemization (er 99 > 1), and their absolute configuration was confirmed by circular dichroism. Isothiocyanate derivatives of natural and unnatural amino acids were evaluated for antibacterial activity on E. coli and S. aureus bacterial strains, where the Citation: Janczewski, Ł.; Kr˛egiel,D.; most active was ITC 9e.
