  戊二酸衍生物的合成及辐射防护性能

  摘要：

  高通量筛选方法突显了某些pulvinic酸衍生物（PAD）在γ和UV辐射以及类Fenton条件下对胸腺嘧啶核苷氧化的显着抗氧化活性。在这里，我们报告了一系列新的亲水性PADs的合成及其在细胞培养中的辐射防护功效的评估。使用基于细胞的荧光测定法，我们表明其中一些化合物具有明显的防止辐射引起的细胞死亡并随后恢复增殖的能力。因此，PAD可被认为是一类新型的辐射防护剂。

  A new series of Cs+, K+ and Na+ chelators: Synthesis, kinetics, thermodynamics and modeling

  摘要：

  The synthesis of two molecules, B1 and B2, based on elements of norbadione A, the natural Cs+ chelator in mushrooms, associated, in the case of B2, with an 18-crown-6 ether is reported. Thermodynamic and kinetic analyses performed in water, ethanol and ethanol/water 9/1 v/v (M1) show in M1 and ethanol that B1 and B2 form stable complexes with Na+, K+ and Cs+. Affinity constants, measured spectrophotometrically in ethanol and M1, by the use of the SPECFIT program, are in the 10(5) and 10(6) range for B1 and B2, respectively. The second-order rate constants are in the 10(6)-10(7) M-1 s(-1) range and the first-order rate constants about unity. The ratios of the second-order/first-order rate constants confirm the thermodynamic results in EtOH. The kinetic processes become much too fast to allow runs in M1. Molecular simulations in EtOH imply the existence of two isomers for each of the Cs+/B1 and Cs+/B2 complexes. With B1, the more stable one is that in which the two enolates are parallel and mimic the alkali-metal inclusion cavity already envisaged for norbadione A. With B2, two similar structures are extracted, in both of which Cs+ is included in the crown ether and capped by the enolate. The affinity of B1 for Cs+ is comparable to that of norbadione A, whereas that of B2 is higher. These results are encouraging as they introduce a new series of alkali chelators which can lead to molecules capable of complexing Cs-137(+) for radioactive decontamination. (C) 2012 Elsevier B. V.

  natural mushroom pigment Norbadione A and three other pulvinic acids were shown by our group to display very efficient antioxidant properties by comparison with a collection of potent molecules including catechols, flavonoids, stilbenes, or coumarins. Despite numerous publications on robust and straightforward synthetic access to pulvinic acids by us and others, no report has been made to unravel the

• Synthesis of Pulvinic Derivatives via TBAF-Mediated Regioselective Opening of an Unsymmetrical Monoaromatic Pulvinic Dilactone

  The synthesis of the monoaromatic pulvinic dilactone I from a tetronic acid derivative is reported. The reaction of 1 with various amines was found to provide the two pulvinamides regioisomers 2a and 2b. Using tetrabutylammonium fluoride (TBAF) as an activator, pulvinamides 2a could be obtained with excellent regioselectivities and good yields. Additions of alcohols to I are also studied, leading to similar observations.
