摘要
冠状病毒(cov)是直径60-140纳米、带正电的单链RNA基因组、具有颗粒状特征的包膜病毒,在21世纪初引发了人类致命肺炎的大规模爆发。COVID-19目前被认为是全球持续的潜在大流行威胁。因此,在抑制病毒传播和灭活病毒的创新方法和技术方面已经做出了相当大的努力,但COVID-19疫苗仍处于研发阶段。这一观点侧重于使用无机基纳米材料、金属配合物和金属偶联物的冠状病毒的传感、检测和治疗应用。合成的无机纳米粒子由于其形态上的相似性,与病毒的蛋白质相互作用强烈,因此,许多抗病毒药物已经通过比色法和电化学测定在体外对不同病毒的有效性进行了测试。以金属配合物为基础的药物,如铋配合物形成了一类有吸引力的药物,具有许多治疗应用,包括定量实时荧光定量PCR (Q-RT-PCR)对SARS-CoV解旋酶的抑制和双解活性,磷酸盐释放分析和放射性分析研究。金属偶联物在抑制sars冠状病毒3Clike蛋白酶和RNA依赖RNA聚合酶(RdRp)复制方面发挥主要作用。我们预计,这些方法将为这些创新传感器的开发提供快速和准确的抗病毒策略,用于检测、抑制和抗病毒活性的冠状病毒。

摘要: Coronaviruses (CoVs) are enveloped viruses with particle-like characteristics and a diameter of 60-140 nm, positively charged, and single-stranded RNA genomes, which caused a major outbreak of human fatal pneumonia in the beginning of the 21st century. COVID-19 is currently considered a continuous potential pandemic threat across the globe. Therefore, considerable efforts have been made to develop innovative methods and technologies for suppressing the spread of viruses as well as inactivating the viruses but COVID-19 vaccines are still in the development phase. This perspective focuses on the sensing, detection and therapeutic applications of CoVs using inorganic- based nanomaterials, metal complexes, and metal-conjugates. Synthetic inorganic- based nanoparticles interact strongly with proteins of viruses due to their morphological similarities, and therefore, numerous antivirals have been tested for efficacy against different viruses in vitro through colorimetric and electrochemical assays. Metal complexes- based agents such as bismuth complexes form an attractive class of drugs with a number of therapeutic applications, including the inhibition and duplex-unwinding activity of SARS-CoV helicase by quantitative real-time PCR (Q-RT-PCR), phosphate release assay and radioassay studies. Metal-conjugates show major effects on inhibiting the 3Clike protease of SARS-CoV and the replication of RNA-dependent RNA polymerase (RdRp). We anticipate that these approaches will provide rapid and accurate antiviral strategies in the development of these innovative sensors for the detection, inhibition and antiviral activities of coronaviruses.

Chalcogen-modified nucleic acid analogues
Chalcogen-modified nucleosides, nucleotides and oligonucleotides have been of great interest to scientific research for many years. The replacement of oxygen in the nucleobase, sugar or phosphate backbone by chalcogen atoms (sulfur, selenium, tellurium) gives these biomolecules unique properties resulting from their altered physical and chemical properties. The continuing interest in ...read more
