Ethyl 1-O-tert-butyldimethylsilyl-2,3-O-isopropylidene-5-[(2′S)-tetrahydropyran-2-yloxy]-d-glycero-α-d-manno-heptofuronate
The title compound {systematic name: (2S,3R)-ethyl 3-[(3aS,4R,6S,6aS)-6-tert-butyl-dimethyl-silyl-oxy-2,2-dimethyl-per-hydro-furo[3,4-d][1,3]dioxol-4-yl]-2-nitro-3-[(S)-tetra-hydro-2H-pyran-2-yl-oxy]propanoate}, C(23)H(41)NO(10)Si, is the product of the Henry reaction of 1-O-tert-butyl-dimethyl-silyl-2,3-O-isopropyl-idene-α-d-lyxo-penta-dialdo-1,4-furan-ose with ethyl nitro-acetate and the subs...
متن کاملPotential Antitumor Activity of 2-O-α-d-Glucopyranosyl-6-O-(2-Pentylheptanoyl)-l-Ascorbic Acid
Intravenous administration of high-dose ascorbic acid (AA) has been reported as a treatment for cancer patients. However, cancer patients with renal failure cannot receive this therapy because high-dose AA infusion can have side effects. To solve this problem, we evaluated the antitumor activity of a lipophilic stable AA derivative, 2-O-α-d-glucopyranosyl-6-O-(2-pentylheptanoyl)-l-ascorbic acid...
متن کاملSynthesis of 3-O- and 4-O-(2-aminoethylphosphono) derivatives of methyl l-glycero-α-d-manno-heptopyranoside
ABSTRACT Phosphoethanolamine derivatives of the bacterial saccharide l-glycero-d-manno-heptose have been prepared using a phosphoramidite-based coupling reaction at position 4 of a side-chain-protected 2,3-O-orthoester methyl heptoside and at position 3 of a 3,4-diol heptoside, respectively. Global deprotection afforded the corresponding 2-aminoethylphosphodiester derivatives as substrates for ...
متن کامل7-Azido-N,N-diethyl-4,5-O-isopropylidene-4-C-methyl-3,6-anhydro-7-deoxy-d-glycero-d-manno-heptonamide
The reaction of 5-azido-5-de-oxy-2,3-O-isopropyl-idene-2-C-methyl-d-ribose with N,N-diethyl-2-(dimethyl-sulfuranyl-idene)acetamide gave the title compound, C(15)H(26)N(4)O(5), as the major product arising from initial formation of an epoxide which was subsequently opened by intra-molecular attack of the free 4-hydroxyl group. X-ray crystallography confirmed the relative stereochemistry of the t...
متن کاملThe cardioprotective effects of 4-O-(2″-O-acetyl-6″-O- p-coumaroyl-β-D-glucopyranosyl)-p-coumaric acid (4-ACGC) on chronic heart failure
The 4-ACGC isolated from BP was prepared to investigate the cardioprotective effects on attenuating chronic heart failure in vivo and in vitro. A chronic heart failure (CHF) rat model was established to investigate the cardioprotective effects of 4-ACGC. From this, several cardiac function indexes were recorded. The inflammatory markers including tumor necrosis factor-α (TNF-α), Interleukin-6 (...
