  Antimicrobial Indole-3-Carboxamido-Polyamine Conjugates Target Bacterial Membranes and Are Antibiotic Potentiators

  摘要：

  Small molecules that can restore the action of legacy antibiotics toward drug-resistant bacteria represent an area of ongoing research interest. We have previously reported indole-3-glyoxylamido and indole-3-acetamido-polyamine conjugates that exhibit intrinsic activity toward bacterial and fungal species, and the ability to enhance the action of doxycycline toward the Gram-negative bacteria Pseudomonas aeruginosa; however, these desirable activities were commonly associated with unfavorable cytotoxicity and/or red blood cell hemolytic properties. In this paper, we report the synthesis and biological investigation of a new class of α,ω-di(indole-3-carboxamido)polyamine derivatives, leading to the identification of several analogues that exhibit antimicrobial- and antibiotic-potentiating activities without detectable cytotoxic or hemolytic properties. 5-Bromo-substituted indole analogues 3 and 12–18 were generally more broad-spectrum in their activity than others in the set, with 13b (polyamine PA-3-6-3) being particularly notable for its anti-Staphylococcus aureus, Acinetobacter baumannii, and Cryptococcus neoformans activities (MIC ≤ 0.28 µM). The same analogue also restored the action of doxycycline toward P. aeruginosa with a 21-fold enhancement, while the corresponding 5-bromo-indole-3-carboxamide-PA3-7-3 analogue was able to enhance the action of both doxycycline and erythromycin toward P. aeruginosa and Escherichia coli, respectively. The analogue 13b was capable of disrupting the bacterial membrane of both S. aureus and methicillin-resistant S. aureus (MRSA) and the outer membrane of P. aeruginosa, suggesting that membrane perturbation could be a mechanism of action of both intrinsic antimicrobial activities and antibiotic potentiation.

  开发二价配体以靶向 CUG 三重重复，这是 1 型强直性营养不良的病原体

  摘要：

  扩展的 CUG 重复转录本 (CUG exp ) 是通过隔离肌盲样 1 蛋白 (MBNL1) 导致 1 型强直性肌营养不良 (DM1) 的病原体，MBNL1 是可变剪接的调节因子。基于先前报道在体外测定中具有活性的配体 ( 1 )，我们提出了一个包含 10个二聚配体 ( 4-13 )的小文库的合成，这些配体的长度、组成和附着点不同链接链。与寡醚接头相比，寡氨基接头对 CUG RNA 的亲和力更大，并且更有效。最有效的体外配体（9) 被证明是水溶性的并且具有细胞和细胞核渗透性，在 DM1 细胞模型中显示 MBNL1 核糖核病灶几乎完全分散。使用延时共聚焦荧光显微镜观察到9的生物活性的直接证据是其在单个活 DM1 模型细胞中分散核糖核病灶的能力。

  Pure compound screening has previously identified the indolglyoxy lamidospermidine ascidian metabolites didemnidine A and B (2 and 3) to be weak growth inhibitors of Trypanosoma brucei rhodesiense (IC50 59 and 44 μM, respectively) and Plasmodium falciparum (K1 dual drug resistant strain) (IC50 41 and 15 μM, respectively), but lacking in selectivity (L6 rat myoblast, IC50 24 μM and 25 μM, respectively). To expand the structure–activity relationship of this compound class towards both parasites, we have prepared and biologically tested a library of analogues that includes indoleglyoxyl and indoleacetic “capping acids”, and polyamines including spermine (PA3-4-3) and extended analogues PA3-8-3 and PA3-12-3. 7-Methoxy substituted indoleglyoxylamides were typically found to exhibit the most potent antimalarial activity (IC50 10–92 nM) but with varying degrees of selectivity versus the L6 rat myoblast cell line. A 6-methoxyindolglyoxylamide analogue was the most potent growth inhibitor of T. brucei (IC50 0.18 μM) identified in the study: it, however, also exhibited poor selectivity (L6 IC50 6.0 μM). There was no apparent correlation between antimalarial and anti-T. brucei activity in the series. In vivo evaluation of one analogue against Plasmodium berghei was undertaken, demonstrating a modest 20.9% reduction in parasitaemia.

  纯化合物筛选之前已确定，indolglyoxy lamidospermidine海鞘代谢物didemnidine A和B（2和3）对锥虫（Trypanosoma brucei rhodesiense）的生长抑制作用较弱（IC50分别为59和44 μM），以及对抗疟原虫（Plasmodium falciparum K1双重耐药株）（IC50分别为41和15 μM），但缺乏选择性（L6大鼠肌母细胞，IC50分别为24 μM和25 μM）。为了扩展这种化合物类别的结构-活性关系，针对这两种寄生虫，我们准备并进行了包括indoleglyoxyl和indoleacetic“封端酸”的类似物库，以及多胺如精胺（PA3-4-3）及其扩展的类似物PA3-8-3和PA3-12-3的生物测试。7-甲氧基取代的indoleglyoxylamides通常表现出最强的抗疟活动（IC50 10–92 nM），但与L6大鼠肌母细胞系相比，选择性程度各异。6-甲氧基indolglyoxylamide类似物是本研究中发现的对T. brucei的最强生长抑制剂（IC50 0.18 μM）；然而，它的选择性也较差（L6 IC50 6.0 μM）。在系列化合物中，抗疟活动与抗T. brucei活动之间没有明显相关性。对一种类似物进行抗Plasmodium berghei的体内评估，显示出寄生血症减少20.9%的适度效果。

  The widespread incidence of antimicrobial resistance necessitates the discovery of new classes of antimicrobials as well as adjuvant molecules that can restore the action of ineffective antibiotics. Herein, we report the synthesis of a new class of indole-3-acetamido-polyamine conjugates that were evaluated for antimicrobial activities against a panel of bacteria and two fungi, and for the ability to enhance the action of doxycycline against Pseudomonas aeruginosa and erythromycin against Escherichia coli. Compounds 14b, 15b, 17c, 18a, 18b, 18d, 19b, 19e, 20c and 20d exhibited strong growth inhibition of methicillin-resistant Staphylococcus aureus (MRSA) and Cryptococcus neoformans, with minimum inhibitory concentrations (MIC) typically less than 0.2 µM. Four analogues, including a 5-bromo 15c and three 5-methoxyls 16d–f, also exhibited intrinsic activity towards E. coli. Antibiotic kill curve analysis of 15c identified it to be a bactericide. While only one derivative was found to (weakly) enhance the action of erythromycin against E. coli, three examples, including 15c, were found to be strong enhancers of the antibiotic action of doxycycline against P. aeruginosa. Collectively, these results highlight the promising potential of α,ω-disubstituted indole-3-acetamido polyamine conjugates as antimicrobials and antibiotic adjuvants.

  由于抗菌药耐药性的广泛存在，因此有必要发现新的抗菌药类别以及能够恢复无效抗生素作用的辅助分子。在此，我们报告了一类新的吲哚-3-乙酰胺基多胺共轭物的合成，并评估了它们对一系列细菌和两种真菌的抗菌活性，以及增强强力霉素对绿脓杆菌和红霉素对大肠杆菌作用的能力。化合物 14b、15b、17c、18a、18b、18d、19b、19e、20c 和 20d 对耐甲氧西林金黄色葡萄球菌（MRSA）和新型隐球菌具有很强的生长抑制作用，最低抑制浓度（MIC）通常低于 0.2 µM。四种类似物，包括一种 5-溴 15c 和三种 5-甲氧基 16d-f，对大肠杆菌也具有内在活性。15c 的抗生素杀灭曲线分析表明它是一种杀菌剂。虽然只有一种衍生物被发现能（弱）增强红霉素对大肠杆菌的作用，但包括 15c 在内的三种衍生物被发现能强烈增强强力霉素对绿脓杆菌的抗生素作用。总之，这些结果凸显了α,ω-二取代吲哚-3-乙酰胺基多胺共轭物作为抗菌剂和抗生素佐剂的巨大潜力。
