  Synthesis and the effect of alkyl chain length on optoelectronic properties of diarylethene derivatives

  摘要：

  Photochromic symmetrical diarylethene derivatives 1a-6a bearing different long alkyl chains at 2-position of thiophene rings have been synthesized and their structures have been determined by single-crystal X-ray diffraction analysis. The effect of alkyl chain length on their optoelectronic properties, such as photochromism in solution as well as in the crystalline phase and electrochemical performance was investigated in detail. These diarylethenes have showed good photochromic behavior both in solution and in the single crystalline phase. Introduction of the long alkyl chains at 2-position of bis(5-formyl-3-thienyl) perfluorocyclopentene increased the absorption coefficients of both open- and closed-ring isomers and induced bathochromic shifts of the maximal wavelength absorption of the closed-ring isomers. The long alkyl chains can also decrease the cyclization/cycloreversion quantum yields and the oxidation potentials. The cyclic voltammetry indicated that the band gap of these diarylethene derivatives was significantly affected by the alkyl chain length. (c) 2007 Elsevier Ltd. All rights reserved.

  pantothenamides show potent antiplasmodial activity, hydrolysis by pantetheinases/vanins present in blood rapidly inactivates them. We herein report the facile synthesis and biological activity of a small library of pantothenamide analogues in which the labile amide group is replaced with a heteroaromatic ring. Several of these analogues display nanomolar antiplasmodial activity against Plasmodium falciparum and/or

  引起疟疾的疟原虫寄生虫正在发展对抗疟药的抗药性，从而为新型抗疟原虫药物提供了动力。尽管泛酰胺显示出有效的抗疟原虫活性，但是血液中存在的泛肽酶/ vanins的水解作用很快使它们失活。我们在本文中报道了泛酰胺类似物小文库的合成和生物活性，该文库中的不稳定酰胺基被杂芳环取代。这些类似物中的几种显示出针对恶性疟原虫和/或诺氏疟原虫的纳摩尔抗疟原虫活性。，并且在泛酸酶存在下稳定。已知的三唑和新型异恶唑衍生物均被进一步表征，并发现它们在体外具有高选择性指数，中等或较高的Caco-2渗透性以及中等或较低的微粒体清除率。尽管它们不能抑制体内伯氏疟原虫的增殖，但所提供的药代动力学和接触时间数据为可能在小鼠中实现抗血浆活性的化合物谱提供了基准，并且应该有助于铅的优化。
