Surface plasmon resonance approach to study drug interactions with SARS-CoV-2 RNA-dependent RNA polymerase highlights treatment potential of suramin
Abstract
\n 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.\n
