Abstract
Sinefungin (A9145) and a related metabolite, A9145C, were potent inhibitors of Newcastle disease virion and vaccinia virion mRNA(guanine-7-)methyl-transferase and vaccinia virion mRNA(nucleoside-2''-)-methyltransferase. Both Sinefungin and A9145C were competitive inhibitors of these S-adenosyl-L-methionine-dependent enzymes having inhibition constants substantially less than S-adenosyl-L-homocysteine. These compounds also inhibited plaque formation by vaccinia virus in mouse [fibroblast] L-cells.
