Viral infections are an important cause of death worldwide. Unfortunately, there is still a lack of antiviral drugs or vaccines for a large number of viruses, and this represents a remarkable challenge particularly for emerging and re-emerging viruses. For this reason, the identification of broad spectrum antiviral compounds provides a valuable opportunity for developing efficient antiviral therapies. Here we report on a class of rhodanine and thiobarbituric derivatives displaying a broad spectrum antiviral activity against seven different enveloped viruses including an HSV-2 acyclovir resistant strain with favorable selectivity indexes. Due to their selective action on enveloped viruses and to their lipid oxidation ability, we hypothesize a mechanism on the viral envelope that affects the fluidity of the lipid bilayer, thus compromising the efficiency of virus-cell fusion and preventing viral entry.
病毒感染是全球死亡的一个重要原因。遗憾的是,目前仍然缺乏针对大量病毒的抗病毒药物或疫苗,这对新出现和再次出现的病毒来说尤其是一个巨大的挑战。因此,鉴定广谱抗病毒化合物为开发高效的抗病毒疗法提供了宝贵的机会。在此,我们报告了一类罗丹宁和硫代巴比妥衍生物,它们对七种不同的包膜病毒(包括一种对 HSV-2 阿昔洛韦耐药的病毒株)具有广谱抗病毒活性,并具有良好的选择性指标。由于它们对包膜病毒的选择性作用及其脂质氧化能力,我们推测病毒包膜上存在一种影响脂质双分子层流动性的机制,从而影响病毒细胞融合的效率并阻止病毒进入。
