Description
2''-C-Methylcytidine (2CMC) is a ribonucleoside with broad-spectrum antiviral activity. It reduces the number of viral plaques in BHK-21 cells infected with dengue type 2, reovirus type 1, West Nile, and yellow fever RNA viruses with EC
50 values of 95, 26, 80, and 75 μM, respectively. 2CMC inhibits hepatitis C virus (HCV) replication (EC
50 = 2.2 μM in a replicon assay) and protects MDBK cells from infection with bovine virus diarrhea virus (BVDV; EC
50 = 2.2 μM) and human coronavirus (HCoV; EC
50 = 90 μM). It also reduces infectious virus yield in BHK-21 cells infected with foot-and-mouth disease virus (FMDV; EC
50 = 6.4 μM) and swine vesicular disease virus (SVDV; EC
50 = 45.2 μM).
In vivo, 2CMC reduces viral shedding to undetectable levels in a mouse model of persistent norovirus infection.
