  Linear TMC-95-Based Proteasome Inhibitors

  摘要：

  We have designed and evaluated 45 linear analogues of the natural constrained cyclopeptide TMC-95A. These synthetically less demanding molecules are based on the tripeptide sequence Y-N-W of TMC-95A. Structural variations in the amino acid side chains and termini greatly influenced both the efficiency and selectivity of action on a given type of active site. Inhibition constants were submicromolar (K-i approximate to 300 nM) despite the absence of the entropically favorable constrained conformation that is characteristic of TMC-95A and its cyclic analogues. These linear compounds were readily prepared and reasonably stable in culture medium and could be optimized to inhibit one, two, or all three proteasome catalytic sites. Cytotoxicity assays performed on a series of human tumor cell lines identified the most potent inhibitors in cells.

  β-Lactam Derivatives as Enzyme Inhibitors: Carboxy Peptidyl Derivatives of (S)-4-Oxoazetidine-2-carboxylate as Peptidomimetics

  摘要：

  4-Oxoazetidine-2-carboxylic acid, protected at the nitrogen by silyl groups, was coupled with amino acid and oligopeptide esters. Desilylation and deprotection of the amino acid residues yielded the free beta -lactam peptides. Structure and properties were elucidated by spectroscopic methods and discussed. Some selected compounds were tested as fibrinogen inhibitors and for thrombocyte aggregation. None of the compounds showed any activity up to a concentration of 10(-5) Mol/l. Some other compounds exhibited a weak inhibitory activity against elastase (PPE).

  modelling and synthetic studies have been carried out on tyrosinyl adenylate and analogues to probe the interactions seen in the active site of the X-ray crystal structure of tyrosyl tRNA synthetase from Bacillus stearothermophilus, and to search for new inhibitors of this enzyme. Micromolar and sub-micromolar inhibitors of tyrosyl tRNA synthetases from both B. stearothermophilus and Staphylococcus aureus have

Encouraged by this data we investigated if the pyrimidine congeners could escape a natural resistance mechanism, involving acetylation of the amine of the aminoacyl group by the bacterial N-acetyltransferases RimL and YhhY.

  氨酰基-tRNA合成酶（aaRSs）催化氨基酸与其同源tRNA的ATP依赖性偶联。aaRSs对于蛋白质翻译至关重要，被认为是开发新型抗菌剂的有希望的目标。5'- O-（N-氨基酰基）-氨磺酰基腺苷（aaSA）是aaRS反应中间体的不可水解类似物，已显示是该酶家族的有效抑制剂，但易于化学不稳定和酶促修饰。为了改善该支架的分子性质，我们合成了一系列碱基取代的aaSA类似物，其包括靶向胞嘧啶，酪氨酰基和异亮氨酰-tRNA合成酶的胞嘧啶，尿嘧啶和N 3-甲基尿嘧啶。在体外九种抑制剂中的七种检测结果表明K i app值在低纳摩尔范围内。为了补充生物化学研究，淋病奈瑟氏球菌亮氨酰tRNA合成酶和大肠杆菌的X射线晶体学结构测定了与新合成的化合物复合的酪氨酰-tRNA合成酶。这些突显了在限定相对抑制活性中碱基部分和靶酶之间的微妙相互作用。受此数据的鼓励，我们研究了嘧啶同源物是否可以逃避天然抗性机制，涉及通

  Aminoacyl-tRNA synthetases (aaRSs) have become viable targets for the development of antimicrobial agents due to their crucial role in protein translation. A series of six amino acids were coupled to the purine-like 7-amino-5-hydroxymethylbenzimidazole nucleoside analogue following an optimized synthetic pathway. These compounds were designed as aaRS inhibitors and can be considered as 1,3-dideazaadenine

  Aminoacyl-tRNA synthetases (aaRSs) are enzymes that precisely attach an amino acid to its cognate tRNA. This process, which is essential for protein translation, is considered a viable target for the development of novel antimicrobial agents, provided species selective inhibitors can be identified. Aminoacyl-sulfamoyl adenosines (aaSAs) are potent orthologue specific aaRS inhibitors that demonstrate

  氨酰基-tRNA合成酶（aaRSs）是一种将氨基酸精确地与其同源tRNA相连的酶。如果可以鉴定出物种选择性抑制剂，则该过程对于蛋白质翻译至关重要，被认为是开发新型抗菌剂的可行目标。氨酰基氨磺酰酰基腺苷（aaSAs）是强直向同源物特异性aaRS抑制剂，在体外表现出纳摩尔亲和力，但吸收受限。继我们之前关于碱基部分取代的工作之后，我们评估了N 3的作用通过合成相应的3-脱氮杂腺苷类似物（aaS3DAs）将腺嘌呤定位在-位。一个典型的生物具有20种不同的aaRS，可以将其分为两个不同的结构类别。因此，我们通过氨基磺酸桥将六种不同的氨基酸（均等地靶向两种酶）偶联到3-deazaadenosine。在评估所获得的类似物的抑制能力时，注意到明显的类别偏倚，与等效的aaSA相比，针对II类酶的aaS3DA类似物的活性丧失。对可用晶体学结构的评估指出了保守水分子的存在，该分子对于II类酶中的碱基识别可能具有
