  醇结构对钨酸二氧化锆醚化和脱水动力学的影响

  摘要：

  线性和支链醚分子作为可从生物质衍生的醇生产的柴油添加剂和润滑剂，最近引起了人们的兴趣。在这项研究中，钨酸锆被鉴定为是一种选择性的绿色固体酸催化剂，用于液相中伯醇的直接醚化，在393 K下对C 6 -C 12线性醇偶联的醚选择性达到> 94％。线性伯醇（C 6 –C 12）对醚化和脱水的表观活化能的影响可忽略不计，证明了同时生产对称和不对称线性醚的可能性。在一系列C 6上的反应甲基支链位置变化的醇表明，取代的醇（2°，3°）和在β-碳上具有支链的醇容易脱水，但是在支链上离OH基团至少三个碳的醇对醚具有高度选择性。合成并测试了一种新型的模型化合物4-己基-1-十二烷醇，以进一步证明这种结构-活性关系。醇结构对选择性的影响趋势与先前提出的醚化和脱水机理相一致，并有助于定义可能的途径，以从生物质衍生的醇中选择性地形成醚。

  Conjugates derived from non-steroidal anti-inflammatory drugs (NSAIDs) and methods of use thereof are disclosed, useful for, inter alia, identifying and localizing the site of pathology and/or inflammation responsible for the sensation of pain in a patient; for identifying the sites of primary, secondary, benign, or malignant tumors; and for diagnosing infection or confirming or ruling out suspected infection. The NSAID-based conjugates contain an imaging moiety. The conjugates concentrate at sites of increased cyclooxygenase expression, thus revealing the sites of increased prostaglandin production, which is correlated with pain and inflammation, and correlated with tumor presence and/or location. Identifying areas of increased COX expressing can also aid in screening for infections.

  披露了来自非甾体抗炎药（NSAIDs）的衍生物及其使用方法，这对于识别和定位患者疼痛感觉的病理和/或炎症部位；识别原发、继发、良性或恶性肿瘤的部位；以及诊断感染或确认或排除疑似感染非常有用。基于NSAID的偶联物含有成像基团。这些偶联物在环氧化酶表达增加的部位富集，从而揭示了前列腺素产生增加的部位，这与疼痛和炎症有关，并与肿瘤存在和/或位置有关。识别COX表达增加的区域也有助于筛查感染。
