  • Isoquercitrin Esters with Mono- or Dicarboxylic Acids: Enzymatic Preparation and Properties

    monocarboxylic acid derivatives, measured as log P, increased with the chain length. Esters with glutaric and adipic acids exhibited hydrophilicity, and the dodecanedioic acid hemiester was more lipophilic. All derivatives were less able to reduce Folin-Ciocalteau reagent (FCR) and scavenge DPPH (1,1-diphenyl-2-picrylhydrazyl) than isoquercitrin; ABTS (2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid)) radical-scavenging
    设计了一系列与一元或二元羧酸的异槲皮苷(槲皮素-3-O-β-d-吡喃葡萄糖苷)酯,以调节亲水性和亲脂性以及生物学特性。异槲皮苷的酯化反应是通过使用Novozym 435(来自南极假丝酵母的脂肪酶)进行直接化学酶反应完成的,该酶接受C 6-至C 12-二羧酸。草酸(C 2),丙二酸(C 4),琥珀酸(C 4)和马来酸(C 4)等较短的不是脂肪酶的底物。单羧酸衍生物的亲脂性,以log P表示,随链长的增加而增加。带有戊二酸和己二酸的酯表现出亲水性,而十二烷二酸半酯则更具亲脂性。与异槲皮苷相比,所有衍生物均无法还原Folin-Ciocalteau试剂(FCR)和清除DPPH(1,1-二苯基-2-吡啶并肼基)。ABTS(2,2'-叠氮基双((3-乙基苯并噻唑啉-6-磺酸))自由基清除活性是可比的。十二烷酸酯和棕榈酸酯在FCR和ABTS清除中活性最低。十二酸和半戊二酸是最强的DPPH清除剂。相反,大

    Aspergillus niger rutinosidase (AnRut) efficiently cleaved a library of rutin glycomimetics - isoquercitrin acylated at C-6′ of its glucosyl moiety. The substrates tested included isoquercitrin substituted at glucosyl C-6′ with acetyl, benzoyl, phenylacetyl, phenylpropanoyl, cinnamyl, vanillyl, galloyl, 4-hydroxybenzoyl, and 3-(4-hydroxy-3-O-methylphenyl)propanoyl. AnRut showed the ability to transglycosylate

  • Enzymatic Acylation of Flavonoids: Effect of the Nature of the Substrate, Origin of Lipase, and Operating Conditions on Conversion Yield and Regioselectivity
    作者:Latifa Chebil、Julie Anthoni、Catherine Humeau、Christine Gerardin、Jean-Marc Engasser、Mohamed Ghoul
    DOI:10.1021/jf071943j
    日期:2007.11.1
    The conversion yield at equilibrium, the initial rate, and the regioselectivity of the enzymatic acetylation of aglycone flavonoids (quercetin, naringenin, hesperetin, and chrysin) were investigated and compared to those obtained with a glycosylated one (isoquercitrin). The effects of a wide range of operating conditions were quantified. Fourier transform infrared spectrometry (FT-IR), NMR, and high performance liquid chromatography electrospray ionization mass spectrometry (HPLC-ESI-MS) analyses showed that for glycosylated flavonoids, in the presence of Candida antarctica (CAL-B), the acetylation occurred on the 2 ''-OH, 3 ''-OH, and 6 ''-OH of the glucose part, while with Pseudomonas cepacea lipase (PSL-C) acetylation takes place on 6 ''-OH of the sugar and 4 '-OH of the B-ring. For aglycone flavonoids, the acetyiation occurred only with IPSL-C on 4 '-OH, 3 '-OH, and 7-OH-1 hydroxyls. The conversion yield and the number and the relative proportions of the synthesized products were found dependent on the nature of the enzyme, the molar ratio, and the flavonoid structure. The initial rate was affected only by the origin of the enzyme.

    Three quercetin glucosides were isolated from flower buds of Japanese butterbur (Petasites japonicus subsp. gigantea Kitam.) together with caffeic acid as the ingredients that had DPPH radical scavenging activity, using the DPPH-HPLC method for measuring the radical scavenging activity. These quercetin glucosides were identified as quercetin 3-O-beta-D-glucoside, quercetin 3-O-beta-D-6''-O-acetylglucoside
