Abstract:
Abstract The caffeoyl derivatives of Stachys leaves (Labiateae) were identified as chlorogenic acid, verbascoside and stachyoside. The latter compound, reported here for the fist time, was shown to be a verbascoside derivative containing an extra glucose residue attached to C-2, C-3 or C-4 of rhamnose. Cotyledonary leaves of Stachys accumulate high levels (8 -16 μmol/g dry tissue) of the three caffeoyl derivatives; all of which decrease significantly in amount during plant growth. Intact organs of the seedling were shown to efficiently incorporate the label from different precursors into caffe

Abstract The first total synthesis of plantamajoside (1), 2-(3′,4′-dihydroxylphenyl)ethyl-4-O-caffeoyl-3-O-(β-D-glucopyranosyl)-β-D-glucopyranoside, which is one of the dihydroxyphenylethyl glycosides (caffeic acid sugar esters), is described. Key intermediate 2, 2-[3′,4′-bis(O-benzyl)phenyl]ethyl 2,6-di-O-acetyl-4-O-[3′,4′-bis(O-benzyl)caffeoyl]-β-D-glucopyranoside was glycosylated with trichloroacetoimidoyl 2,3,4,6-tetra-O-acetyl-α-D-glycopyranoside (3) to afford plantamajoside derivative 4a, 2-[3′,4′-bis(O-benzyl)phenyl]ethyl 2,6-di-O-acetyl-4-O-[3′,4′-bis(O-benzyl)caffeoyl]-3-O-(2,3,4,6-te

Abstract:
Bioassay-directed fractionation of an antioxidant methanol extract of the leaves of Chrozophora senegalensis using DPPH assay led to the isolation of three new flavonoid glycosides, quercetin 3-O-(6″-caffeoyl)-β-D-glucopyranoside-3′-O-β-D-glucopyranoside (1), quercetin 3-methyl ether-7-O-α-L-rhamnopyranosyl-(1→6)-(2″-p-coumaroyl)-β-D-glucopyranoside (2), acacetin 7-O-(6″-p-coumaroyl)-β-D-glucopyranoside (3), along with five known flavonoids, one phenolic derivative, and three megastigmane glycosides. Their structures were established on the basis of detailed spectral analysis. All isolated com

Abstract:
One new monoterpene glycoside (1), one new phenyl glycoside (2), one new caffeoyl derivative (3), were isolated from Scindapsus officinalis (Roxb.) Schott., along with four known compounds (4–7). Structures of the isolated compounds were elucidated by extensive analysis of spectroscopic data, especially 2D NMR data and comparison with literatures. All isolates were evaluated for anti-inflammatory activity against nitric oxide (NO) production in vitro. Compounds 3 and 7 exhibited moderate inhibitory effects on NO production with IC50 values of 12.2 ± 0.8 and 18.9 ± 0.3 μM, respectively.

Abstract:
Kaempferol is a well-known antioxidant found in many plants and plant-based foods. In plants, kaempferol is present mainly in the form of glycoside derivatives. In this work, we focused on determining the effect of kaempferol and its glycoside derivatives on the expression level of genes related to the reduction of oxidative stress—NFE2L2, NQO1, SOD1, SOD2, and HO-1; the enzymatic activity of superoxide dismutases; and the level of glutathione. We used HL-60 acute promyelocytic leukemia cells, which were incubated with the anticancer drug etoposide and kaempferol or one of its three glycoside

Abstract:
The outer layer of purple sweet potato is removed during processing; however, this layer serves as a potential source of phenolics, especially anthocyanins. Herein, the phenolic composition and antioxidant activity were determined for the inner and outer layers of five purple sweet potato cultivars (‘Sinjami’, ‘Jami’, ‘Danjami’, ‘Yeonjami’, and ‘Borami’) harvested in Korea. Anthocyanins were identified using ultra-high-performance liquid chromatography coupled with electrospray ionization quadrupole time-of-flight mass spectrometer (UHPLC-(ESI)-qTOF-MS) and ultra-high-performance liquid chroma

Abstract:
Le syndrome métabolique (SMet) se caractérise par une obésité abdominale qui induit un cercle pernicieux auto-entretenu, dans lequel un état inflammatoire de bas grade et un stress oxydatif vont favoriser l'insulino-résistance pour conduire à terme au diabète de type II. Pour tenter d’empêcher ces troubles physiologiques, un régime alimentaire et une activité physique régulière sont proposés aux personnes à risque. Souvent, le traitement médicamenteux s’avère indispensable et expose le patient à une poly médication prolongée et a ces effets préjudiciables à long terme. Ce travail de thèse cons

Le syndrome métabolique comme le diabète de type 2 sont des pathologies chroniques souvent étroitement liées. Le syndrome métabolique via des dysfonctionnements physiologiques qui s'auto-entretiennent et s'amplifient conduira au diabète de type 2. Les dysfonctionnement majeurs sont l'obésité abdominale, l'inflammation et le stress oxydant tissulaire et enfin l'insulino-résistance des tissus sensibles à l'insuline. Il convient donc de lutter efficacement contre ces dysfonctionnements afin de lutter contre ces pathologies chroniques. Les travaux de l'équipe dans laquelle j'ai effectué ma thèse o
