  Role of the hydrophobic moiety of tumor promoters. Synthesis and activity of 2-alkylated benzolactams

  摘要：

  The size and position of a hydrophobic moiety on a benzolactam skeleton, which reproduces the active conformation and biological activity of teleocidins, play an important role in the appearance of the activity. Compounds with alkyl groups of various sizes and shapes at the 2-position of benzolactam were synthesized. Structure-activity results indicate that a hydrophobic substituent at the C-2 position plays a critical role in the appearance of biological activities, as in the case of substitution at C-9.

  摘要：

  脂肪酸的氧基官能化（FAs）是设计用于生物基/可生物降解的聚合物，表面活性剂和燃料的新型合成途径的关键步骤。在这里，我们展示了一种稳定的FAα-羟化酶（P450Jα）的分离和表征，该酶催化了H 2广泛的FA（C6：0-C16：0）和油酸（C18：1）的选择性转化。O 2作为氧化剂。在优化的反应条件下，P450Jα生成的α-羟基酸均具有> 95％的区域选择性，高比活度（最高15.2 U mg -1）和氧化剂与产物的有效偶联（最高85％）。相对于生产率（TON = 394 min -1），月桂酸（C12：0）被证明是极好的底物）。在制备规模上，以补料分批方式补充H 2 O 2时，C12：0的转化率达到83％（0.9 g L -1）。在相似的条件下，P450Jα可以高选择性，高收率（1.1 g L -1；分离产率为79％）进一步实现油酸的首次生物催化α-羟基化（100 mL规模下88％的转化率）

  Chemical and biocatalytic synthesis of non‐canonical α‐amino acids (ncAAs) from renewable feedstocks and using mild reaction conditions has not efficiently been solved. Here, we show the development of a three‐step, scalable and modular one‐pot biocascade for linear conversion of renewable fatty acids (FAs) into enantiopure l‐α‐amino acids. In module 1, selective α‐hydroxylation of FAs is catalyzed

  2-OH-18:1(9 c) methyl ester as well as the ethyl ester of 3-PFBO-O-12:0 (ISTD-2) was synthesized. ISTD-1 served as a recovery standard whereas ISTD-2 was used for GC/MS measurements. The whole-sample cleanup consisted of accelerated solvent extraction of dry bovine milk, addition of ISTD 1, saponification, conversion of fatty acids into methyl esters by use of boron trifluoride, separation of the methyl

  2-和3-羟基脂肪酸（2-和3-OH-FAs）是鞘脂和细菌中报告的生物活性物质。人们对它们在食物中的存在知之甚少。因此，开发了一种适用于牛乳脂肪中痕量OH-FAs测定的方法。将OH-FAs（和样品中的常规脂肪酸）转化为甲酯，然后用五氟苯甲酰氯（PFBO）将羟基衍生化，得到PFBO-O-FA甲酯。这些具有强电子亲和力的衍生物是通过在所选离子监测模式下使用电子捕获负离子通过气相色谱与质谱联用确定的（GC / ECNI-MS-SIM）。事实证明，该方法对PFBO-O-FA甲酯具有高度的敏感性和选择性。为了分析样品，使用了两个内标。为此，9，来自2-OH-18：1（9 c）甲酯的10-dideutero-2-OH-18：0甲酯（ISTD-1）以及3-PFBO-O-12：0的乙酯-2）被合成。ISTD-1用作回收标准，而ISTD-2用于GC / MS测量。整个样品净化包括加速溶剂萃取干牛乳，添加ISTD
