  配体设计的简单变化即可控制金属-有机骨架的互穿和吸气特性

  摘要：

  在金属-有机骨架（MOF）化学中，互穿作用极大地影响了气体的吸附性能。但是，关于如何控制互穿以及互穿是否能提高气体吸收能力，尚缺乏系统的研究。本文中，我们报告了一个互穿的示例，该示例仅通过在相同的有机结构单元中存在碳-碳双键或单键来简单地控制互穿，并提供了对这些相似构架的气体吸收性质的比较，这些构架的不同之处仅在于它们的程度不同互穿。通过[Zn（NO 3）2 ] ⋅6 H的溶剂热反应制备了非互穿（SNU‐70）和双互穿（SNU‐71）立方网。2 Ó在Ñ，Ñ -diethylformamide（DEF）与4-（2-羧基乙烯基）苯甲酸分别酸和4-（2-羧基乙基）苯甲酸。它们具有几乎相同的结构，但非互穿框架的孔径（约9.0×9.0Å）比互穿框架（约2.5×2.5Å）大得多。通过使用超临界CO 2激活MOF，得到SNU-70'和SNU-71'。对SNU-71'的PXRD模式的仿真表明，在去除客体时

• Terminal Alkenes from Acrylic Acid Derivatives via Non-Oxidative Enzymatic Decarboxylation by Ferulic Acid Decarboxylases
  作者：Godwin A. Aleku、Christoph Prause、Ruth T. Bradshaw-Allen、Katharina Plasch、Silvia M. Glueck、Samuel S. Bailey、Karl A. P. Payne、David A. Parker、Kurt Faber、David Leys

  Fungal ferulic acid decarboxylases (FDCs) belong to the UbiD‐family of enzymes and catalyse the reversible (de)carboxylation of cinnamic acid derivatives through the use of a prenylated flavin cofactor. The latter is synthesised by the flavin prenyltransferase UbiX. Herein, we demonstrate the applicability of FDC/UbiX expressing cells for both isolated enzyme and whole‐cell biocatalysis. FDCs exhibit

  真菌阿魏酸脱羧酶 (FDC) 属于 UbiD 酶家族，通过使用异戊二烯化黄素辅因子催化肉桂酸衍生物的可逆（脱）羧化。后者由黄素异戊烯基转移酶 UbiX 合成。在此，我们证明了 FDC/UbiX 表达细胞对于分离酶和全细胞生物催化的适用性。 FDC表现出高活性，总周转数(TTN)高达55000，周转频率(TOF)高达370 min -1 。共溶剂相容性研究表明，FDC 对某些有机溶剂的耐受性高达 20% v/v。利用 Holo-FDC 的体外（脱）羧酶活性以及全细胞生物催化剂，我们对三种 FDC 进行了底物分析研究，为活性的结构决定因素提供了见解。 FDC 对多种 C3 处带有（杂）环或烯属取代基的丙烯酸衍生物表现出广泛的底物耐受性，转化率高达 >99%。 FDC 的合成效用通过制备规模的脱羧得到了证明。
• Synthesis and Anti-influenza Activities of Novel Baicalein Analogs
  作者：Shu-Ting Chung、Pei-Yu Chien、Wen-Hsin Huang、Chen-Wen Yao、An-Rong Lee

  DOI：10.1248/cpb.c13-00897

  日期：——

  A series of novel flavones derivatives were synthesized based on modification of the active ingredients of a traditional Chinese medicine Scutellaria baicalensis GEORGI and screened for anti-influenza activity. The synthetic baicalein (flavone) analogs, especially with the B-rings substituted with bromine atoms, were much more potent than oseltamivir or ribavirin against H1N1 Tamiflu-resistant (H1N1 TR) virus and usually with more favorable selectivity. The most promising were 5b, 5c, 6b and 6c, all displaying an 50% effective concentration (EC50) at around 4.0–4.5 µM, and a selective index (SI=50% cytotoxic concentration (CC50)/EC50)>70. For seasonal H3N2-infected influenza virus, both 5a and 5b with SI >17.3 indicated superior to ribavirin. The flavonoids having both not-naturally-occurring bromo-substituted B-rings and appropriate hydroxyls positioning on the A-rings might be critical in determining the activity and selectivity against H1N1-Tamiflu-resistant infected influenza viruses.

  一系列新型黄酮衍生物是基于对传统中药黄芩（Scutellaria baicalensis GEORGI）活性成分的修饰合成的，并进行了抗流感活性筛选。合成的大黄素（黄酮）类似物，特别是B环上带有溴原子取代的类似物，对H1N1达菲耐药（H1N1 TR）病毒的活性远超奥司他韦或利巴韦林，并且通常具有更优越的选择性。最有希望的化合物是5b、5c、6b和6c，它们的50%有效浓度（EC50）都在4.0–4.5 µM左右，选择指数（SI=50%细胞毒性浓度（CC50）/EC50）>70。对于季节性H3N2流感病毒感染，5a和5b的SI均大于17.3，优于利巴韦林。这些具有非天然溴取代B环和A环上适当羟基位置的黄酮类化合物可能在决定抗H1N1达菲耐药流感病毒的活性和选择性方面起关键作用。

  日期：2012.1

  An efficient and reusable heterogeneous catalytic assembly of PdCl2 held in ionic liquid brushes has been synthesized and an environmentally‐friendly procedure was developed for coupling aryl iodides with acrylic acid. These reactions were conducted in water under aerobic conditions with water‐insoluble or even solid aryl iodides and they proceeded smoothly and cleanly without any organic co‐solvent
