  Discovery and Structure Relationships of Salicylanilide Derivatives as Potent, Non-acidic P2X1 Receptor Antagonists

  摘要：

  Antagonists for the ATP-gated ion channel receptor P2X1 have potential as antithrombotics and for treating hyperactive bladder and inflammation. In this study, salicylanilide derivatives were synthesized based on a screening hit. P2X1 antagonistic potency was assessed in 1321N1 astrocytoma cells stably transfected with the human P2X1 receptor by measuring inhibition of the ATP-induced calcium influx. Structure-activity relationships were analyzed, and selectivity versus other P2X receptor subtypes was assessed. The most potent compounds, N-[3,5-bis(trifluoromethyl)phenyl]-5-chloro-2-hydroxybenzamide (1, IC50 0.0192 mu M) and N-[3,5-bis(trifluoromethyl)phenyl]-4-chloro-2-hydroxybenzamide (14, IC50 0.0231 mu M), displayed >500-fold selectivity versus P2X2 and P2X3, and 10-fold selectivity versus P2X4 and P2X7 receptors, and inhibited collagen-induced platelet aggregation. They behaved as negative allosteric modulators, and molecular modeling studies suggested an extracellular binding site. Besides selective P2X1 antagonists, compounds with ancillary P2X4 and/or P2X7 receptor inhibition were discovered. These compounds represent the first potent, non-acidic, allosteric P2X1 receptor antagonists reported to date.

  Infections caused by multidrug-resistant (MDR) bacteria, particularly Gram-negative bacteria, are an escalating global health threat. Often clinicians are forced to administer the last resort antibiotic colistin, however colistin resistance is becoming increasingly prevalent, giving rise to the potential for a situation in which there are no treatment options for MDR Gram-negative infections. The development of adjuvants that circumvent bacterial resistance mechanisms is a promising orthogonal approach to the development of new antibiotics. We recently disclosed that the known IKK-β inhibitor IMD-0354 potently suppresses colistin resistance in several Gram-negative strains. In this disclosure, we explore the structure activity relationship (SAR) between the IMD-0354 scaffold and colistin resistance suppression, and identify several compounds with more potent activity than the parent against highly colistin resistant strains of Acinetobacter baumannii and Klebsiella pneumoniae.

  由多药耐药（MDR）细菌引起的感染，特别是革兰氏阴性细菌，是一种不断加剧的全球健康威胁。通常情况下，临床医生被迫使用最后的抗生素科利星，然而科利星耐荐性越来越普遍，导致可能出现无法治疗MDR革兰氏阴性细菌感染的情况。开发能够规避细菌耐药机制的辅助剂是开发新抗生素的一种有前途的正交方法。我们最近披露，已知的IKK-β抑制剂IMD-0354能够有效抑制几种革兰氏阴性菌株对科利星的耐药性。在这一披露中，我们探讨了IMD-0354骨架与科利星耐药抑制之间的结构活性关系（SAR），并确定了几种比母体更具有强效活性的化合物，对鲍曼不动杆菌和肺炎克雷伯氏菌高度耐科利星的菌株具有更强的活性。

  salts, or dimethyl(phenyl)sulfonium salts with trifluoroacetamides affords substituted aromatic amides in good to excellent yields. These nickel-catalyzed reactions are enabled by C–CF3 bond activation using Dy2O3 as an additive. The current protocol provides versatile and scalable routes for accessing a wide variety of substituted aromatic amides. Moreover, the protocol described in this work overcomes

  酰胺键在天然和合成有机分子中很突出，在各个领域都具有活性。在众多的酰胺合成方法中，取代预先存在的 (O)C-N 部分是一种尚未开发的酰胺合成策略。在这项工作中，我们公开了一种用于脂肪族和芳香族三氟乙酰胺脱氟芳基化产生芳香族酰胺的新方案。芳基硼酸、三甲氧基苯基硅烷、二芳基碘盐或二甲基（苯基）锍盐与三氟乙酰胺的机械化学诱导反应以良好至极好的收率提供取代的芳族酰胺。这些镍催化的反应是通过使用 Dy 2 O 3的 C–CF 3键活化来实现的作为添加剂。当前的协议提供了通用且可扩展的路线，用于访问各种取代的芳香酰胺。此外，这项工作中描述的协议克服了先前报告的方法中的缺点和局限性。

  A series of salicylanilides was synthesized based on a high-throughput screening hit against Mycobacterium tuberculosis. A free phenolic hydroxyl on the salicylic acid moeity is required for activity, and the structure-activity relationship of the aniline ring is largely driven by the presence of electron withdrawing groups. We synthesized 94 analogs exploring substitutions of both rings and the linker region in this series and we have identified multiple compounds with low micromolar potency. Unfortunately, cytotoxicity in a murine macrophage cell line trends with antimicrobial activity, suggesting a similar mechanism of action. We propose that salicylanilides function as proton shuttles that kill cells by destroying the cellular proton gradient, limiting their utility as potential therapeutics. Published by Elsevier Ltd.
