  一种通过 1H NMR 光谱测定含有芳基甘油片段的化合物的相对和绝对构型的巧妙方法

  摘要：

  建立了一种简明的方法来确定芳基甘油的相对和绝对构型，该构型取决于非对映亚甲基质子（H-3）的化学位移差异（ Δδ ），通过1 H NMR 光谱。当使用 DMSO- d 6作为首选溶剂时，苏型构型对应于较大的 Δ δ H3a–H3b值 (>0.15 ppm)，而赤型构型 (<0.07 ppm) 对应于较小的值。此外，借助莰酰氯的简单酰化反应确定了绝对构型。在苏式对映体中， 1R , 2R构型的Δδ值为<0.15ppm， 1S , 2S构型的Δδ值为>0.20ppm。赤型对映体中，1 R ,2 S的Δδ值为>0.09 ppm，1 S ,2 R的Δδ值为<0.05 ppm。值得注意的是，这个经验规则在CDCl 3中是无效的。此外，该方法还通过量子1 H NMR计算得到验证。

  New inhibitors of colony spreading in Bacillus subtilis and Bacillus anthracis

  摘要：

  We have recently characterized sliding motility in Bacillus subtilis strains that lack functional flagella, and here describe the discovery of inhibitors of colony spreading in these strains as well as the aflagellate pathogen, Bacillus anthracis. Aflagellate B. subtilis strains were used to screen for new types of antibacterials that might inhibit colony spreading on semi-solid media. From a diverse set of organic structures, p-nitrophenylglycerol (NPG), an agent used primarily in clinical laboratories to control Proteus swarming, was found to inhibit colony spreading. The four stereoisomers of NPG were synthesized and tested, and only the 1R,2S-(1R-anti) and 1R,2R-(1R-syn) NPG isomers had significant activity in a quantitative colony spreading assay. Twenty-six NPG analogs and related structures were synthesized and tested to identify more active inhibitors. p-Methylsulfonylphenylglycerol (p-SPG), but not its ortho or meta analogs, was found to be the most effective of these compounds, and synthesis and testing of all four p-SPG stereoisomers showed that the 1R-anti-isomer was the most active with an average IC50 of 16 mu M (3-5 mu g mL (1)). For B. anthracis, the colony-spreading IC50 values for 1R-anti-SPG and 1R-anti-NPG are 12 mu M (2-4 mu g mL (1)) and >150 mu M, respectively. For both Bacillus species tested, 1R-anti-SPG inhibits colony spreading of surface cultures on agar plates, but is not bacteriostatic or bacteriocidal in liquid cultures. Work is in progress to find the cellular target(s) of the NPG/SPG class of compounds, since this could lead to an understanding of the mechanism(s) of colony spreading as well as design and development of more potent inhibitors for the control of B. anthracis surface cultures.

  established to determine the relative and absolute configurations of aryl-glycerols that depend on the chemical shift differences (Δδ) of the diastereotopic methylene protons (H-3) by 1H NMR spectroscopy. When using DMSO-d6 as the preferred solvent, the threo configuration corresponded to a larger ΔδH3a–H3b value (>0.15 ppm), whereas the erythro configuration (<0.07 ppm) corresponded to a smaller value
