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. -

Flavonoid Application in Treatment of Oral Cancer-A Review
European Journal of Molecular & Clinical Medicine ISSN 2515-8260 Volume 07, Issue 01, 2020 FLAVONOID APPLICATION IN TREATMENT OF ORAL CANCER-A REVIEW Sudarsan R1, Lakshmi T2, Anjaneyulu K3 1Undergraduate student, Saveetha Dental College and Hospitals, Saveetha Institute of Medical and Technical Sciences, Saveetha University, Chennai - 77 2Associate Professor, Department of Pharmacology, Saveetha Dental College and Hospitals, Saveetha Institute of Medical and Technical Sciences, Saveetha University, Chennai - 77 3 Reader, Department of Conservative Dentistry and Endodontics, Saveetha Dental College and Hospitals, Saveetha Institute of Medical and Technical Sciences, Saveetha University, Chennai - 77 ABSTRACT A wide range of organic compounds that are naturally occurring called flavonoids are primarily found in a large variety of plants. Some of the sources include tea, wine, fruits, grains, nuts and vegetables. There are a number of studies that have proven that a strong association exists between intake of dietary flavonoid and its effects on mortality in the long run. Flavonoids at non-toxic concentrations are known to demonstrate a wide range of therapeutic biological activities in organisms. The contribution of flavonoids in prevention of cancer is an area of great interest in current research. A variety of studies, including in vitro experiments and human trials and even epidemiological investigations, provide compelling evidence which imply that flavonoids’ effects on cancer in terms of chemoprevention and chemotherapy is significant. As the current treatment methods possess a number of drawbacks, the anticancer potential demonstrated by flavonoids makes them a reliable alternative. Various studies have focussed on flavonoids’ anti-cancer potential and its possible application in the treatment of cancer as a chemopreventive agent. -

ABSTRACT Title of Document: BIOLOGICAL
ABSTRACT Title of Document: BIOLOGICAL EFFICACY, MECHANISMS OF ACTIONS OF SOY-DERIVED PHYTOALEXIN GLYCEOLLINS IN PREVENTION OF CHRONIC DISEASES Haiqiu Huang, Doctor of Philosophy, 2014 Directed By: Professor Liangli (Lucy) Yu Department of Nutrition and Food Science Cardiovascular disease (CVD) is the leading cause of deaths worldwide. Prostate cancer is the most prevalent cancer in U.S. male population. Diet-induced hypercholesterolemia and chronic inflammation promote the development of both CVD and prostate cancer. Glyceollins are a group of soy phytoalexins possessing a variety of biological activities. This research project focused on characterizing glyceollins’ bioactivities in alleviating cholesterol dysregulation, prevention of prostate cancer, and regulating gut microbiome. The first part of the project aimed to evaluate glyceollins’ cholesterol- lowering effect in-vivo. Male golden Syrian hamsters were fed high-fat diet with or without glyceollins supplementation for 28 days. Glyceollins supplementation led to a significant reduction of plasma VLDL, hepatic cholesterol esters and total lipid content. Consistent with changes in circulating cholesterol, glyceollins supplementation also altered expression of the genes related to cholesterol metabolism in the liver. The second part of the study aimed to evaluate glyceollins’ effect in reducing prostate cancer tumor growth in a xenograft model. An initial delayed appearance of tumor was observed in a PC-3 xenograft model. However, no difference in tumor sizes was observed in a LNCaP xenograft model. Extrapolation analysis of tumor measurements indicated that no difference in sizes was expected for both PC-3 and LNCaP tumors. Glyceollins had no effect on the androgen responsive pathway, its proliferation, cell cycle, or on angiogenesis genes in tumor and xenobiotic metabolism, cholesterol transport, and inflammatory cytokine genes in liver. -

Year: 2014 Number of pages: 257 Flavonoid glycosides are natural plant secondary metabolites exhibiting many physicochemical and biological properties. Glycosylation usually improves flavonoid solubility but access to flavonoid glycosides is limited by their low production levels in plants. In this thesis work, the focus was placed on the development of new glucodiversification routes of natural flavonoids by taking advantage of protein engineering. Two biochemically and structurally characterized recombinant transglucosylases, the amylosucrase from Neisseria polysaccharea and the α-(1→2) branching sucrase, a truncated form of the dextransucrase from L. Mesenteroides NRRL B-1299, were selected to attempt glucosylation of different flavonoids, synthesize new α-glucoside derivatives with original patterns of glucosylation and hopefully improved their water-solubility. -
Identification of Apigenin and Luteolin in Artemisia Annua L. for the Quality
Phadungrakwittaya et al. Identification of Apigenin and Luteolin inArtemisia annua L. for the Quality Control Rattana Phadungrakwittaya*, Sirikul Chotewuttakorn*, Manoon Piwtong**, Onusa Thamsermsang**, Tawee Laohapand**, Pravit Akarasereenont*,** *Department of Pharmacology, **Center of Applied Thai Traditional Medicine, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok 10700, Thailand. ABSTRACT Objective: To identify active compounds and establish the chemical fingerprint ofArtemisia annua L. for the quality control. Methods: Thin-layer chromatography (TLC) conditions were developed to screen for 2 common flavonoids (apigenin and luteolin). Three mobile phases were used to isolate these flavonoids in 80% ethanolic extract of A. annua. Hexane : ethyl acetate : acetic acid (31:14:5, v/v) and toluene : 1,4-dioxane : acetic acid (90:25:4, v/v) were used in normal phase TLC (NP-TLC), and 5.5% formic acid in water : methanol (50:50, v/v) were used in reverse phase TLC (RP-TLC). Chromatograms were visualized under visible light after spraying with Fast Blue B Salt. Apigenin and luteolin bands were checked by comparing their Rf values and UV-Vis absorption spectra with reference markers. Results: Apigenin and luteolin were simultaneously detected with good specificity in RP-TLC condition, while only apigenin was detected in NP-TLC condition. Apigenin band intensity was higher than luteolin band intensity in both conditions. Conclusion: This knowledge can be applied to the development of quality control assessments to ensure product efficacy and consistency.
