  摘要：

  一种用于确定生物体或生物样本中结核分枝杆菌种类存在的方法，该方法包括向生物体或生物样本中添加一种探针分子，该探针分子包括底物和标记，该探针分子可以被结核分枝杆菌所吸收，通过对标记的存在做出反应的探测器确定结核分枝杆菌的存在，可选地，在施加刺激后进行；适用的探针分子包括包含标记和底物的化合物，该标记可以被对标记的存在做出反应的探测器检测到，可选地，在施加刺激后进行，其特征在于该化合物能够与抗原85B（Ag85B）的活性位点结合，从而能够与所选活性位点中的两个或更多氨基酸同时形成氢键，所选活性位点包括Arg 43、Trp 264、Ser126、His 262和Leu 42，或者抗原85A（Ag85A）或抗原85C（Ag85C）中对应的氨基酸，其中至少一个与Ser126形成氢键。

  A method for determining the presence of mycobacteria species in an organism or biological sample, the method comprising adding to the organism or biological sample a probe molecule comprising a substrate and a label, which probe molecule can be incorporated into mycobacteria, the presence of mycobacteria being determined by a detector responsive to the presence of the label, optionally after applying a stimulus; suitable probe molecules include compounds comprising a label and a substrate, which label is can be detected by a detector responsive to the presence of the label, optionally after applying a stimulus, characterised by compound being able to engage with the active site of Antigen 85B (Ag85B) such that it can form simultaneous hydrogen bonds with two or more amino acids in the active site selected from Arg 43, Trp 264, Ser126, His 262 and Leu 42, or the corresponding amino acids in Antigen 85A (Ag85A) or Antigen 85C (Ag85C), at least one of which is with Ser126.

  Mycobacterium tuberculosis Antigen 85 enzymes are vital to the integrity of the highly impermeable cell envelope and are potential therapeutic targets. Kinetic analysis using a label-free assay revealed both mechanistic details and a substrate profile that allowed the design and construction of a selective in vitro mechanism-based inhibitor.
• Direct Synthesis of Maradolipids and Other Trehalose 6-Monoesters and 6,6′-Diesters

  It was shown that reaction of trehalose with 1 equiv of a fatty acid in pyridine promoted by 1 equiv of the uronium-based coupling agent 2-(1H-benzotriazole-1-y1)-1,1,3,3-tetramethyluronium tetrafluoroborate (TBTU) at room temperature gives a good yield of the primary ester accompanied by small amounts of the diprimary ester using hexanoic, palmitic, and oleic acids as examples. Reactions using 2 equiv of the fatty acids gave the symmetrical diesters. The monoesters were reacted with different fatty acids to give nonsymmetric 6,6'-diesters in very good yields. Compounds synthesized include the most abundant component of the very complex maradolipid mixture, 6-O-(13-methyltetradecanoyl)-6'-O-oleoyltrehalose, and a component potentially present in this mixture, 6-O-(12-methyltetradecanoyl)-6'-O-oleoyltrehalose, a derivative of an ante fatty acid. The CS-C6 rotameric populations of 6-O-monoesters, symmetrical 6,6'-diesters, and 2,6,6'-triesters of fatty acids were calculated from the values of the H5-H6R and H5-H6S coupling constants and found to be similar to those found for glucose. The rotameric populations of the monosubstituted glucose residues in the 2,6,6'-triesters was altered considerably to favor the gt rotamer, presumably because of attraction between the 2- and 6'-fatty acid chains.
