    Inhibition of Enterovirus A71 by a Novel 2-Phenyl-Benzimidazole Derivative
    摘要:
    Enterovirus A71(EV-A71)感染已经成为全球范围内一个重要的公共卫生关注点。EV-A71的流行事件已在全球范围内报道,并这一系列的爆发事件加剧了人们对EV-A71可能成为公共卫生威胁的担忧。近年来,欧洲国家也出现了广泛的A71肠道病毒感染。EV-A71感染会引起手足口病(HFMD)、咽峡炎和发热。然而,它有时也会引发各种神经并发症,包括脑炎、无菌性脑膜炎、肺水肿和急性弛缓性麻痹。我们鉴定了新的苯并咪唑衍生物,并描述了它们在体外的细胞毒性和广谱抗肠道病毒活性。其中,衍生物2b对EV-A71表现出有趣的活性,因此被选中进行进一步的研究。化合物2b被证明能够保护细胞单层免受EV-A71诱导的细胞病理性损害,其EC50为3微米。此外,当以20和80微米的浓度处理Vero-76细胞时,细胞层明显免受坏死和凋亡的影响。化合物2b减少了病毒对Vero-76细胞的吸附,并在加入时间试验中表现出最高的效果。此外,衍生物2b减少了病毒对宿主细胞的渗透。此外,2b不影响肠道单层的通透性,没有显示出毒性作用。对化合物2b对EV-A71的功效进行的详细研究显示,在低浓度下,它对病毒滴度有剂量依赖性的降低。机制研究表明,我们的衍生物可以通过减少病毒与宿主细胞的结合和渗入来抑制病毒内吞作用。药代动力学和毒性预测验证了化合物2b作为进行进一步体内实验的良好候选。

    Compounds 2–8, 15, 17, and 18 showed significant inhibitory activities. All the inhibitors were found to be competitive inhibitors, except compound 17, which was a mixed type inhibitor. The substituents (R) in para and ortho positions of phenyl ring B, apparently played a key role in the inhibitory potential of the series. Compounds 1–20 were also studied for their cytotoxicity profile by using 3T3 mouse

    geometry of the synthesized complexes 1 and 2 was confirmed by single-crystal X-ray diffraction study. A wide range of benzimidazole derivatives (32 examples) up to 94% isolated yield has been derived via acceptorless dehydrogenative coupling of primary alcohols with derivatives of o-phenylenediamines. The present protocol operates smoothly with only 1 mol% catalyst loading. Furthermore, the mechanistic

    Enterovirus A71 (EV-A71) infection has emerged as a significant public health concern at the global level. Epidemic events of EV-A71 have been reported worldwide, and this succession of outbreaks has heightened concern that EV-A71 may become a public health threat. In recent years, widespread A71 enterovirus also occurred in European countries. EV-A71 infection causes hand-foot-mouth disease (HFMD), herpangina, and fever. However, it can sometimes induce a variety of neurological complications, including encephalitis, aseptic meningitis, pulmonary edema, and acute flaccid paralysis. We identified new benzimidazole derivatives and described theirin vitrocytotoxicity and broad-spectrum anti-enterovirus activity. Among them, derivative 2b resulted in interesting activity against EV-A71, and therefore it was selected for further investigations. Compound 2b proved to be able to protect cell monolayers from EV-A71-induced cytopathogenicity, with an EC50 of 3 µM. Moreover, Vero-76 cells resulted in being significantly protected from necrosis and apoptosis when treated with 2b at 20 and 80 µM. Compound 2b reduced viral adsorption to Vero-76 cells, and when evaluated in a time-of-addition assay, the derivative had the highest effect when added during the infection period. Moreover, derivative 2b reduced viral penetration into host cells. Besides, 2b did not affect intestinal monolayers permeability, showing no toxic effects. A detailed insight into the efficacy of compound 2b against EV-A71 showed a dose-dependent reduction in the viral titer, also at low concentrations. Mechanism of action investigations suggested that our derivative can inhibit viral endocytosis by reducing viral attachment to and penetration into host cells. Pharmacokinetic and toxicity predictions validated compound 2b as a good candidate for furtherin vivoassays.
