    Easy-To-Access Quinolone Derivatives Exhibiting Antibacterial and Anti-Parasitic Activities
    摘要:
    结核分枝杆菌(Mtb)的细胞壁具有独特的结构组织,包括高脂质含量混合多糖。这使得细胞壁成为一道难以透过的强大屏障,对亲水性试剂不透水。此外,在寄主感染期间,Mtb寄居在无血管坏死性肉芽肿和空洞中的巨噬细胞内,这使得细菌免受大多数抗生素的作用。为了克服这些保护屏障,文献中推荐了一类具有亲脂性特征的新型抗结核药物。在这里,合成了一系列亲脂性杂环喹诺酮化合物,并在体外评估了对Mtb的pMSp12::GFP菌株、两种原虫寄生虫(疟原虫和布鲁氏锥虫)以及对ESKAPE病原体的活性。所得化合物表现出不同的抗Mtb活性,MIC90值在0.24-31 µM范围内。对抗疟原虫和布鲁氏锥虫的交叉筛选,确定了几种具有抗原虫活性的化合物,活性范围在0.4-20 µM之间。这些化合物通常对ESKAPE病原体无活性,只有8c、8g和13号化合物对金黄色葡萄球菌和鲍曼不动杆菌表现出中等至差的活性。

    Abstract

    Interaction of 6-amino-1-ethyl-4-oxoquinoline-3-carboxylic ester (7) with chloral hydrate and hydroxylamine hydrochloride gave the corresponding isonitroso-acetamido derivative 8 which, upon treatment with concentrated sulfuric acid, was converted regioselectively into 1,2,9-trioxopyrrolo[ 3,2- f ]quinoline-8-carboxylic acid (3). This novel tricyclic system was isolated in good yield as a stable hydrate 3H. Structural assignments of the new compounds are based on microanalytical and spectral (MS and NMR) data

    presence of trifluoroacetic acid alterations were observed in their photophysical profile, especially regarding their emissive response. The ester derivatives 1-alkyl-6-amino-4-oxo-1,4-dihydroquinoline-3-carboxylate exhibit a more significant increase in intensity (>2 times-fold) and a considerable redshift (∼90 nm), leading to emission colour change from blue to green in acidic condition. The changes were
    4-喹诺酮衍生物在药物化学中被广泛探索,用于开发治疗不同病理的候选药物。然而,它们的光学特性仍未得到充分利用。在这项工作中,研究了 3-酰基-6-氨基-4-喹诺酮衍生物家族的光物理性质,突出了它们对酸的光学行为。虽然这些物质没有表现出明显的溶剂化显色性,但在三氟乙酸存在下在它们的光物理分布中观察到了变化,特别是在它们的发射响应方面。酯衍生物 1-烷基-6-氨基-4-氧代-1,4-二氢喹啉-3-羧酸酯表现出更显着的强度增加(> 2 倍)和相当大的红移(~90 nm),导致在酸性条件下,发射颜色从蓝色变为绿色。这些变化非常敏感,可检测到 MeCN 中低至 10 μM 的质子浓度。该分子系统通过 NMR 和 DFT 计算进行了研究,表明 1,3-二酮是首选的质子化位点。酮和羧基之间的分子内氢键的建立导致LUMO 稳定性和几乎共面的质子化结构,有利于荧光。值得注意的是,分子内或分子间氢键的存在对其

The 2,5-diamino-1,4-benzoquinone structure is associated with an anti-prion profile and, considering the biodynamic properties associated with 4-quinolones, in this work, 6-amino-4-quinolones derivatives and their respective benzoquinone dimeric hybrids were synthesized and had their bioactive profile evaluated through their ability to prevent prion conversion.

    朊病毒病或传染性海绵状脑病是一种神经退行性疾病,具有较长的潜伏期和渐进的临床演变,可导致死亡。它们的发病机制的特点是细胞朊病毒蛋白——PrP C——在其感染性亚型——PrP Sc 中的构象变化-它可以形成在脑组织中沉淀的聚合物聚集体。目前,还没有针对这些疾病的有效治疗方法。2,5-二氨基-1,4-苯醌结构与抗朊病毒谱相关,考虑到与 4-喹诺酮相关的生物动力学特性,在这项工作中,6-氨基-4-喹诺酮衍生物及其各自的苯醌二聚体杂合体被合成,并通过它们防止朊病毒转化的能力评估了它们的生物活性特征。两种杂化物,即 2,5-二氯-3,6-双((3-羧基-1-戊基-4-喹诺酮-6-基)氨基)-1,4-苯醌 ( 8e ) 和 2,5- dichloro-3,6-bis((1-benzyl-3-carboxy-4-quinolone-6-yl)amino)-1,4-benzoquinone ( 8f),因

    We described the synthesis of a new congener series of 1,2,3-triazolyl-4-oxoquinolines and evaluated their ability to inhibit oseltamivir (OST)-resistant influenza strains. Oxoquinoline derivative 1i was the most potent compound within this series, inhibiting 94% of wild-type (WT) influenza neuraminidase (NA) activity. Compound 1i inhibited influenza virus replication with an EC50 of 0.2 mu M with less cytotoxicity than OST, and also inhibited different OST-resistant NAs. These results suggest that 1,2,3-triazolyl-4-oxoquinolines represent promising lead molecules for further anti-influenza drug design. Published by Elsevier Ltd.

    The cell wall of Mycobacterium tuberculosis (Mtb) has a unique structural organisation, comprising a high lipid content mixed with polysaccharides. This makes cell wall a formidable barrier impermeable to hydrophilic agents. In addition, during host infection, Mtb resides in macrophages within avascular necrotic granulomas and cavities, which shield the bacterium from the action of most antibiotics. To overcome these protective barriers, a new class of anti-TB agents exhibiting lipophilic character have been recommended by various reports in literature. Herein, a series of lipophilic heterocyclic quinolone compounds was synthesised and evaluated in vitro against pMSp12::GFP strain of Mtb, two protozoan parasites (Plasmodium falciparum and Trypanosoma brucei brucei) and against ESKAPE pathogens. The resultant compounds exhibited varied anti-Mtb activity with MIC90 values in the range of 0.24–31 µM. Cross-screening against P. falciparum and T.b. brucei, identified several compounds with antiprotozoal activities in the range of 0.4–20 µM. Compounds were generally inactive against ESKAPE pathogens, with only compounds 8c, 8g and 13 exhibiting moderate to poor activity against S. aureus and A. baumannii.
