• Phenylalanine Ammonia Lyase Catalyzed Synthesis of Amino Acids by an MIO-Cofactor Independent Pathway
  作者：Sarah L. Lovelock、Richard C. Lloyd、Nicholas J. Turner

  DOI：10.1002/anie.201311061

  日期：2014.4.25

  MIO‐independent reaction pathway, which proceeds in a non‐stereoselective manner and results in the generation of both L‐ and D‐phenylalanine derivatives, is described. The mechanism of the MIO‐independent pathway is explored through isotopic‐labeling studies and mutagenesis of key active‐site residues. The results obtained are consistent with amino acid deamination occurring by a stepwise E1cB elimination mechanism

  苯丙氨酸解氨酶 (PAL) 属于 4-亚甲基咪唑-5-酮 (MIO) 辅因子依赖性酶家族，其负责在真核生物和原核生物中将L-苯丙氨酸转化为反式肉桂酸。在高氨浓度条件下，这种脱氨反应是可逆的，因此人们对开发 PAL 作为非天然氨基酸的对映选择性合成的生物催化剂有相当大的兴趣。在此发现了一种以前未观察到的竞争性 MIO 非依赖性反应途径，该反应途径以非立体选择性方式进行并导致L-和D的产生描述了-苯丙氨酸衍生物。通过同位素标记研究和关键活性位点残基的诱变探索了 MIO 非依赖性途径的机制。获得的结果与通过逐步 E 1 cB 消除机制发生的氨基酸脱氨基作用一致。

  日期：2015.4.3

  The first Fe-facilitated decarboxylative cross-coupling reaction between α-oxocarboxylic acids and acrylic acids in aqueous solution has been developed. This transformation is characterized by its wide substrate scope and good functional group compatibility utilizing inexpensive and easily accessible reagents, thus providing an efficient and expeditious approach to an important class of α,β-unsaturated

  已经开发出水溶液中α-氧代羧酸与丙烯酸之间的第一个铁促进的脱羧交叉偶联反应。该转化的特征在于其底物范围宽和使用廉价且易于获得的试剂的良好官能团相容性，从而为生物活性化合物中常见的重要一类α，β-不饱和羰基化合物提供了一种有效而快捷的方法。在随后的官能化反应中也证明了偶联产物的合成潜力。初步的机理研究表明，该过程涉及自由基途径：
• Acrylamide derivatives as antiallergic agents. I. Synthesis and structure-activity relationships of N-((4-substituted 1-piperazinyl)alkyl)-3-(aryl and heteroaryl)acrylamides.

  A new series of acrylamide derivatives (7-10) were synthesized. Antiallergic activity of these compounds was evaluated and their structure-activity relationships were examined. Compounds 10d, N[4-(4-diphenylmethyl-1-piperazinyl)buthyl]3-(3-pyridyl)acrylamide, showed antiallergic activity equivalent or superior to that of ketotifen in the rat passive cutaneous anaphylaxis (PCA) test by oral administration. Compound 10d, unlike ketotifen, had more potent in vitro 5-lipoxygenase inhibitory activity than caffeic acid, whereas its in vitro antihistamine activity was weaker than that of ketotifen. In addition, its inhibitory activity against histamine release from rat mast cells was approximately two-thirds as potent as that of disodium cromoglycate (DSCG). Compound 10d is a promising agent for treating a variety of allergic diseases.

  一系列新的丙烯酰胺衍生物（7-10）被合成。对这些化合物的抗过敏活性进行了评估，并考察了它们的结构-活性关系。化合物10d，即N[4-(4-二苯甲基-1-哌嗪基)丁基]3-(3-吡啶基)丙烯酰胺，在口服给药的大鼠被动皮肤过敏反应（PCA）测试中显示出与酮替芬相当或更优越的抗过敏活性。与酮替芬不同，10d在体外对5-脂氧合酶的抑制活性比咖啡酸更强，而其体外抗组胺活性则弱于酮替芬。此外，它对大鼠肥大细胞释放组胺的抑制活性约为色甘酸二钠（DSCG）的三分之二。化合物10d是一种有前途的多种过敏性疾病治疗药物。
