    A Practical Synthesis of L-FMAU from L-Arabinose
    摘要:
    A practical synthesis of 2'-deoxy-2'-fluoro-5-methyl-beta-L-arabinofuranosyl uracil (14, L-FMAU) was developed from L-arabinose. L-Arabinose was converted to L-ribose 5, which was used for the synthesis of bromosugar 12 via 2,3,5-O-tribenzoyl-1-O-acetyl-beta-L-ribofuranose 8, which was subjected to condensation with silylated thymine and the resulting protected L-FMAU 13 was deprotected to afford L-FMAU in 14 steps in 8 % overall yield.

    Based on the structural scaffolds of natural products, two series of flavonoid derivatives, for a total of twelve compounds, were designed and synthesized as potential human telomerase inhibitors. Using a modified TRAP-PCR assay, compound 5c exhibited the most potent inhibitory activity against human telomerase with an IC50 value of less than 50 μM. In vitro, the results demonstrated that compound

    The X-ray diffraction analysis, (13)C CP MAS NMR spectra and powder X-ray diffraction patterns were obtained for selected methyl glycosides: alpha- and beta-d-lyxopyranosides (1, 2), alpha- and beta-l-arabinopyranosides (3, 4), alpha- and beta-d-xylopyranosides (5, 6) and beta-d-ribopyranoside (7) and the results were confirmed by GIAO DFT calculations of shielding constants. In X-ray diffraction analysis
    对于选定的甲基糖苷,获得了X射线衍射分析,(13)CP CP MAS NMR光谱和粉末X射线衍射图:α-和β-d-lyxopyranosides(1、2),α-和β-1-阿拉伯喃糖苷(3、4),α-和β-d-喃糖苷(5、6)和β-d-核喃糖苷(7),其结果通过GIAO DFT计算屏蔽常数得到了证实。在1和2的X射线衍射分析中,由于异头效应,在1的分子中观察到所选键的特征缩短和延长,并且在1和2的晶格中观察到不同图案的氢键。另外,在1中观察到了另外一个具有环氧原子参与的分子内氢键。固态和溶液之间观察到的化学位移差异来自构象效应和各种分子间氢键的形成。源于分子间氢键的化学位移变化的幅度小于构象效应。此外,对4、5和7进行的粉末X射线衍射(PXRD)显示,7以两种多晶型物的混合物形式存在,其中之一可能由两个非等价分子组成。

    In the present study, a new oleanane-type triterpenoid saponin, pulsatilloside F (1), along with 21 known compounds (2–22), were isolated from the root of Pulsatilla koreana. Their chemical structures were elucidated by mass, 1H-, 13C-NMR, correlation spectroscopy (COSY), heteronuclear multiple quantum coherence (HMQC) and heteronuclear multiple bond connectivity (HMBC) spectroscopy. Anti-inflammatory effects of the compounds were evaluated in terms of inhibitory of tumor necrosis factor α (TNF-α) secretion in the lipopolysaccharide (LPS)-stimulated murine RAW264.7 macrophage cell line. Compounds 19 and 20 exhibited particularly inhibitory effects with respective IC50 values of 0.32 and 0.65 µm. Compounds 1–4, 7 and 10–13 exhibited inhibitory effects with inhibition rates up to 41.55–73.76% at a concentration of 5 µm, respectively.

    This paper describes a method for the preparation of purine analogs using the solid-phase approach. Nucleoside bases were constructed on Merrifield resin by sequential displacement of purine dichloride with amines, and after detachment, the purine analogs were condensed with d,l-ribofuranoside compounds by the Vorbruggen method. Thereof, l-ribofuranoside was prepared from l-arabinose via the selective
