RH12

RH12 is a dual inhibitor of SARS-CoV-2-related RNA-dependent RNA polymerase (RdRp, IC50 of 4.42 nM) and human transmembrane serine protease 2 (TMPRSS2, IC50 of 4.2 nM). It demonstrates antiviral activity by inhibiting viral replication and absorption, showing 90.5% virucidal effect in Vero-E6 cells. Additionally, RH12 inhibits Calu-3 cell viability with an IC50 of 17.5 nM.
