  Structure–activity relationship study of novel necroptosis inhibitors

  摘要：

  Necroptosis is a regulated caspase-independent cell death mechanism that results in morphological features resembling necrosis. It can be induced in a FADD-deficient variant of human Jurkat T cells treated with TNF-alpha. 5-(1H-Indol-3-ylmethyl)-2-thiohydantoins and 5-(1H-indol-3-ylmethyl)hydantoins were found to be potent necroptosis inhibitors (called necrostatins). A SAR study revealed that several positions of the indole were intolerant of substitution, while small substituents at the 7-position resulted in increased inhibitory activity. The hydantoin ring was also quite sensitive to structural modifications. A representative member of this compound class demonstrated moderate pharmacokinetic characteristics and readily entered the central nervous system upon intravenous administration.

  halogenation by halogenases or incorporation of haloindoles using tryptophan synthase. Introduction of these Trp derivatives into RGD peptides as a benchmark system was performed to investigate their influence on bioactivity. Halotryptophan-containing RGD peptides display increased affinity toward integrin αvβ3 and enhanced selectivity over integrin α5β1. In addition, bromotryptophan was exploited as a platform

  使用通过卤化酶的酶促卤化或使用色氨酸合酶掺入卤代吲哚来合成在吲哚部分具有不同取代基的1-和d-卤代色氨酸的阵列。将这些Trp衍生物引入RGD肽作为基准系统以研究其对生物活性的影响。含Halotryptophan-RGD肽显示增加的亲和力朝向整合素α v β 3和增强的过整合素α选择性5 β 1。另外，铃木色氨酸被铃木-宫浦交叉耦合（SMC）开发为后期多样化的平台，从而产生了新的自然的联芳基序。这些肽显示出增强的朝向α亲和力v β 3，良好的亲和力，以α v β 8，和显着的选择性超过α 5 β 1和α IIB β 3，同时具有荧光性质。在体外证明了其作为探针的可行性。进行了广泛的分子动力学模拟，以阐明这些后期多样化的环状RGD肽的NMR和高效液相色谱（HPLC）数据，并进一步表征其构象偏好。

  Co‐expression of the halogenase RebH with GroEL/ES and fusion of the flavin reductase RebF to MBP enabled production of both enzymes on scales sufficient for preparative regioselective oxidative halogenation of arenes. The activity and selectivity of RebH contrasts with those reported for the structurally homologous halogenase PrnA, which only enabled halogenation of nonnatural substrates at their most electronically

  d-Tryptophan and its derivatives are important precursors of a wide range of indole-containing pharmaceuticals and natural products. Here, we developed a one-pot biocatalytic process enabling the synthesis of d-tryptophans from indoles in good yields and high enantiomeric excess (91% to >99%). Our method couples the synthesis of l-tryptophans catalyzed by Salmonella enterica tryptophan synthase with
