  Synthesis and structure–activity relationships studies of brartemicin analogs as anti-invasive agents

  摘要：

  Brartemicin是一种由Nonomuraea属放线菌产生的基于海藻糖的肿瘤细胞侵袭抑制剂。为了寻找更有效的抗侵袭剂并研究结构—活性关系，研究人员通过两条合成路线从α,α-D-海藻糖合成了一系列19种brartemicin类药物，并评估了它们的抗侵袭活性。化合物4f，6,6′-二(2,3-二甲氧基苯甲酰基)-α,α-D-海藻糖，比天然的brartemicin更为有效。它对小鼠结肠26-L5、结肠癌SW620、黑素瘤B16-BL6和乳腺MDA-MB-231细胞的侵袭抑制作用的IC50值分别为0.15、2.35、4.12和2.61μM。类药物4p，6,6′-二(3,4-二甲氧基肉桂酰基)-α,α-D-海藻糖，在体外对小鼠结肠26-L5癌细胞的侵袭抑制作用与brartemicin相当。这些新型基于海藻糖的化合物的结构—活性关系进行了总结。

  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.

  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.

  Brartemicin is a trehalose-based inhibitor of tumor cell invasion produced by the actinomycete of the genus Nonomuraea. In order to find more potent anti-invasive agents and study the structure–activity relationships, a series of 19 brartemicin analogs were prepared via two synthetic routes from α,α-D-trehalose and evaluated for their anti-invasive activities. Compound 4f, 6,6′-bis(2,3-dimethoxybenzoyl)-α,α-D-trehalose, was more potent than the natural brartemicin. It inhibited the invasion of murine colon 26-L5, colon carcinoma SW620, melanoma B16-BL6 and breast MDA-MB-231 cells with IC50 values of 0.15, 2.35, 4.12 and 2.61 μM, respectively. Analog 4p, 6,6′-bis(3,4-dimethoxycinnamoyl)-α,α-D-trehalose, was as potent as brartemicin against invasion of murine colon 26-L5 carcinoma cells in vitro. The structure–activity relationships of these novel trehalose-based compounds were summarized.
