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.

Flavonoid compounds potentially inhibit the oxidation of low-density lipoprotein (Ox-LDL) that triggers the generation of a series of oxidation byproducts playing important roles in atherosclerosis development. The diverse inhibitory effects of different flavonoid phytochemicals on Ox-LDL might be closely associated with their intrinsic structures. In current work, we investigated the effects of eight flavonoid phytochemicals in high purity (>95%) with similar core structure on the susceptibility of LDL to Cu 2+ -induced oxidative modification. The results indicated that quercetin, rutin, isoquercitrin, hesperetin, naringenin, hesperidin, naringin and icariin could reduce the Cu 2+ -induced-LDL oxidation by 59.56 ±±±7.03, 46.53 ±±±2.09, 40.52 ±±±4.65, 22.67 ±±±1.68, 20.87 ±±±2.43, 12.34 ±±±2.09, 10.87 ±±±1.68 and 3.53 ±±±3.20%, respectively.

  • FDA Proposes Sunscreen Regulation Changes February 2019
    FDA Proposes Sunscreen Regulation Changes February 2019 The U.S. Food and Drug Administration (FDA) regulates sunscreens to ensure they meet safety and eectiveness standards. To improve the quality, safety, and eectiveness of sunscreens, FDA issued a proposed rule that describes updated proposed requirements for sunscreens. Given the recognized public health benets of sunscreen use, Americans should continue to use broad spectrum sunscreen with SPF 15 or higher with other sun protective measures as this important rulemaking eort moves forward. Highlights of FDA’s Proposals Sunscreen active ingredient safety and eectiveness Two ingredients (zinc oxide and titanium dioxide) are proposed to be safe and eective for sunscreen use and two (aminobenzoic acid (PABA) and trolamine salicylate) are 1 proposed as not safe and eective for sunscreen use. FDA proposes that it needs more safety information for the remaining 12 sunscreen ingredients (cinoxate, dioxybenzone, ensulizole, homosalate, meradimate, octinoxate, octisalate, octocrylene, padimate O, sulisobenzone, oxybenzone, avobenzone). New proposed sun protection factor Sunscreen dosage forms (SPF) and broad spectrum Sunscreen sprays, oils, lotions, creams, gels, butters, pastes, ointments, and sticks are requirements 2 proposed as safe and eective. FDA 3 • Raise the maximum proposed labeled SPF proposes that it needs more data for from SPF 50+ to SPF 60+ sunscreen powders. • Require any sunscreen SPF 15 or higher to be broad spectrum • Require for all broad spectrum products SPF 15 and above, as SPF increases, broad spectrum protection increases New proposed label requirements • Include alphabetical listing of active ingredients on the front panel • Require sunscreens with SPF below 15 to include “See Skin Cancer/Skin Aging alert” on the front panel 4 • Require font and placement changes to ensure SPF, broad spectrum, and water resistance statements stand out Sunscreen-insect repellent combination 5 products proposed not safe and eective www.fda.gov.

The methanolic extract of leaves of different mulberry varieties namely S-13, S-54, BR-2, S-36 and S-1 which belongs to Morus alba and Morus indica were subjected for the phytochemical screening. The results obtained from the HPLC analysis, revealed that the methanolic extracts of mulberry leaves samples of S-36 and S-1 varieties contain more amount of phenolics and flavonoids. The in vitro FRAP assay clearly indicate that S-1 mulberry leaf extract have maximum significant FRAP concentration at 800 µL/mL and 1000 µL/mL (0.408 ± 0.001 mmol FeSO4/100 g dried sample and 0.410 ± 0.001 mmol FeSO4/100 g dried sample, respectively) a significant source of natural anti-oxidant, which might be helpful in preventing the progress of various oxidative stresses.

    THESIS COMPARISON OF DOSE-DEPENDENT OUTCOMES IN INDUCTION OF CYTOGENOTOXIC RESPONSES BY NOVEL GLUCOSYL FLAVONOIDS Submitted by Anya Engen Department of Environmental and Radiological Health Sciences In partial fulfillment of the requirements For the degree of Master of Science Colorado State University Fort Collins, Colorado Spring 2014 Master’s Committee: Advisor: Takamitsu Kato Co-advisor: William Hanneman Marie Legare Gerrit Bouma Copyright by Anya Engen 2014 All Rights Reserved ABSTRACT COMPARISON OF DOSE-DEPENDENT OUTCOMES IN INDUCTION OF CYTOGENOTOXIC RESPONSES BY NOVEL GLUCOSYL FLAVONOIDS The flavonoids quercetin, and its glucosides isoquercetin and rutin, are phytochemicals commonly consumed in plant-derived foods. They are associated with potential health- promoting effects such as anti-inflammation, anti-viral, anti-carcinogenesis, neuro- and cardio- protection, etc. Semi-synthetic water soluble quercetin glucosides, maltooligosyl isoquercetin (MI), monoglucosyl rutin (MO) and maltooligosyl rutin (MA) were developed to overcome solubility challenges for improved incorporation in food and medicinal applications. Quercetin and its glucosides are known to induce genetic instability and decrease cell proliferation, which are possible mechanisms of anti-carcinogenesis in in vitro and animal studies. Using an in vitro system of Chinese hamster ovary (CHO) cells, this thesis project examined the differences in cytogenotoxic responses induced by natural and novel flavonoids. Treatments with flavonoids at a concentration range of 0.1 and 1,000 ppm induced sister chromatid exchanges (SCE) and micronuclei (MN) in CHO cells. Compared to spontaneous occurrences, significant increases in SCE and MN were observed in both natural and synthetic flavonoid-treated cells in a dose- dependent manner. The natural flavonoids exhibited greater potency than the synthetic compounds, where quercetin was most potent.
