The SARS-CoV-2 RNA-dependent RNA polymerase (RdRp) is essential for virus replication, therefore it is a promising drug target. Here we present a surface plasmon resonance approach to study the interaction of RdRp with drugs in real time. We monitored the effect of favipiravir, ribavirin, sofosbuvir triphosphate PSI-7409 and suramin on RdRp binding to RNA immobilized on the chip. Suramin precluded interaction of RdRp with RNA and even displaced RdRp from RNA.

研究药物与 SARS-CoV-2 RNA 依赖性 RNA 聚合酶相互作用的表面等离子共振方法突显了苏拉明的治疗潜力



SARS-CoV-2 RNA依赖性RNA聚合酶(RdRp)对于病毒复制至关重要,因此它是一个有前途的药物靶点。在这里,我们提出了一种表面等离子共振方法来实时研究 RdRp 与药物的相互作用。我们监测了法匹拉韦、利巴韦林、三磷酸索磷布韦 PSI-7409 和苏拉明对 RdRp 与固定在芯片上的 RNA 结合的影响。苏拉明阻止了 RdRp 与 RNA 的相互作用,甚至取代了 RNA 中的 RdRp。
