  An evaluation of Minor Groove Binders as anti- Trypanosoma brucei brucei therapeutics

  摘要：

  A series of 32, structurally diverse MGBs, derived from the natural product distamycin, was evaluated for activity against Trypanosoma brucei brucei. Four compounds have been found to possess significant activity, in the nanomolar range, and represent hits for further optimisation towards novel treatments for Human and Animal African Trypanosomiases. Moreover, SAR indicates that the head group linking moiety is a significant modulator of biological activity. (C) 2016 The Authors. Published by Elsevier Masson SAS.

  A series of head to head linked dimers of heterocyclic amino acids has been prepared for investigation of affinity and selectivity in binding to the minor groove of DNA. The selection of targets for synthesis was led by computer based design. Several novel dicarboxylic acid linkers including indoles, phenanthrenes, a fluorenone, and a bisbenzothiophene have been included. Analysis of binding to DNA

  已经制备了一系列首尾相连的杂环氨基酸二聚体，用于研究与DNA小沟结合的亲和力和选择性。合成目标的选择由基于计算机的设计主导。已经包括几种新颖的二羧酸连接基，包括吲哚，菲，芴酮和双苯并噻吩。通过印迹分析与DNA的结合表明对衍生自2,7-二氢菲二羧酸的化合物具有很高的亲和力，并且对包含至少4个AT对的AT富集区域具有主要选择性，但具有跨越两个CG碱基对的能力。

  Nine novel lexitropsins were synthesized by linking two netropsin-like moieties through three different dicarboxylic acids; 9,10-dihydro-2,7-phenanthrenedicarboxylic acid; [(3-[(carboxymethyl)amino]carbonyl}benzoyl)amino]acetic acid and indole-2,5-dicarboxylic acid. The netropsin residues were modified by the use of N-isopentylpyrrole, 5-methylthiophene or 5-isopropylthiazole heterocyclic building blocks in place of the usual N-methylpyrrole. The compounds were tested against five gram-positive bacteria: Staphylococcus aureus, Streptomyces faecalis, methicillin resistant Staphylococcus aureus, Enterobacter cloacae, Mycobacterium fortuitum, three gram-negative bacteria: Klebsiella aerogenes, Proteus vulgaris, Escherichia coli and three fungi: Aspergillus niger, Candida albicans and Aspergillus nidulans. Some of the compounds showed significant inhibitory effects on the growth of the microorganisms.

  The free-living amoeba Acanthamoeba castellanii is responsible for the central nervous infection granulomatous amoebic encephalitis and sight-threatening infection Acanthamoeba keratitis. Moreover, no effective treatment is currently present, and a combination drug therapy is used. In this study, twelve DNA minor groove binders (MGBs) were synthesized and tested for their antiamoebic activity via amoebicidal, encystation, excystation, and cytopathogenicity assays. It was found that the compounds MGB3, MGB6, MGB22, MGB24, and MGB16 significantly reduce amoeba viability to 76.20%, 59.45%, 66.5%, 39.32%, and 43.21%, respectively, in amoebicidal assays. Moreover, the compounds MGB6, MGB20, MGB22, MGB28, MGB30, MGB32, and MGB16 significantly inhibit Acanthamoeba cysts, leading to the development of only 46.3%, 39%, 30.3%, 29.6%, 27.8%, 41.5%, and 45.6% cysts. Additionally, the compounds MGB3, MGB4, MGB6, MGB22, MGB24, MGB28, MGB32, and MGB16 significantly reduce the re-emergence of cysts to trophozoites, with viable trophozoites being only 64.3%, 47.3%, 41.4%, 52.9%, 55.4%, 40.6%, 62.1%, and 51.7%. Moreover, the compounds MGB3, MGB4, and MGB6 exhibited the greatest reduction in amoeba-mediated host-cell death, with cell death reduced to 41.5%, 49.4%, and 49.5%. With the following determined, future in vivo studies can be carried out to understand the effect of the compounds on animal models such as mice.

  自由生活的阿米巴原虫 Acanthamoeba castellanii 是造成中枢神经感染肉芽肿阿米巴脑炎和危及视力感染 Acanthamoeba 角膜炎的罪魁祸首。此外，目前还没有有效的治疗方法，只能采用联合药物治疗。本研究合成了 12 种 DNA 小沟结合剂（MGBs），并通过阿米巴杀灭试验、阿米巴囊肿形成试验、阿米巴外囊形成试验和细胞致病性试验测试其抗阿米巴活性。结果发现，在杀阿米巴试验中，化合物 MGB3、MGB6、MGB22、MGB24 和 MGB16 能显著降低阿米巴的存活率，分别为 76.20%、59.45%、66.5%、39.32% 和 43.21%。此外，化合物 MGB6、MGB20、MGB22、MGB28、MGB30、MGB32 和 MGB16 还能显著抑制阿卡阿米巴囊肿，使囊肿发育率分别降至 46.3%、39%、30.3%、29.6%、27.8%、41.5% 和 45.6%。此外，化合物 MGB3、MGB4、MGB6、MGB22、MGB24、MGB28、MGB32 和 MGB16 还能显著减少包囊向滋养体的再萌发，有活力的滋养体只占 64.3%、47.3%、41.4%、52.9%、55.4%、40.6%、62.1% 和 51.7%。此外，MGB3、MGB4 和 MGB6 化合物对阿米巴介导的宿主细胞死亡的降低幅度最大，分别降低了 41.5%、49.4% 和 49.5%。有了以下确定的结果，今后就可以开展体内研究，以了解化合物对小鼠等动物模型的影响。
