    1H NMR光谱显示1,2,3-三醇的立体化学:原理与应用
    摘要:
    介绍了1,2,3- prim,sec,sec- triols的三(α-甲氧基-α-苯基乙酸)酯衍生物的构象组成。这些构象已由理论和实验数据确定(例如,能量和化学位移计算,圆二色性(CD)实验,耦合常数分析,对映选择性氘化实验和低温NMR光谱研究)。由于在最显著构象异构体的各向异性的影响的详细分析1 1 H NMR谱所支持的之间的相关性1 1 H NMR谱(Δ δ RS的H(3')和值|Δ(Δ δ RS)| 参数)和基板的绝对配置。该研究还允许根据邻偶合常数和相对化学位移来鉴定Pro - R和Pro-S亚甲基质子。

    comparison of the 1H NMR spectra of the tris-(R)- and the tris-(S)-MPA ester derivatives. An experimental demonstration of this correlation with 24 triols of known absolute configuration and a protocol using two parameters-Deltadelta(RS)(H3) and the difference between Deltadelta RS (H2) and Deltadelta RS (H3) = absolute value (Delta(Deltadelta RS))-for its application to the determination of the absolute

    The autoxidation reaction of l-ascorbic acid (ASA) in methanol without metal ion catalysis was studied. Besides l-threonolactone (THL) and oxalic acid (OXA), methyl l-threonate, and threonic acid were identified as initial autoxidation products of ASA, which were the C(2)-C(3) fission product via the C(2) oxygen adduct of ASA. This pathway is different from the one via dehydro-l-ASA (DASA), which has

  • Substrate-like water soluble lipase inhibitors from Filipendula kamtschatica
    作者:Eisuke Kato、Michitsugu Yama、Ryo Nakagomi、Toshiro Shibata、Keizo Hosokawa、Jun Kawabata

    Filipendula kamtschatica is a plant utilized as a traditional medicine by Ainu people in Japan, but its chemical constituents are not much studied. Pancreatic lipase inhibitors are a promising tool for the treatment of obesity. We searched for natural lipase inhibitors from F. kamtschatica and two new compounds were isolated along with the known flavonoid glycoside. The structure elucidation of new compounds revealed these two to be 2-O-caffeoyl-4-O-galloyl-L-threonic acid and 3-O-caffeoyl-4-O-galloyl-L-threonic acid, which can be recognized as a pancreatic lipase's substrate-like structure. The isolated compounds all showed an inhibitory activity against porcine pancreatic lipase and one of the isomer, 3-O-caffeoyl-4-O-galloyl-L-threonic acid, possessed the most potent activity with IC50 value showing an order lower value compared to others. The substrate-like structure of the new compounds seemed to be important for their activity. (c) 2012 Elsevier Ltd. All rights reserved.
