N-glycoside formation. A number of the rhodanine derivatives, especially those with nitro or chloro groups in the aromatic ring, showed antibacterial activity. N-beta-D-Glucopyranosyl-5-(4-nitrobenzylidene) rhodanine showed antiviral activity by inhibition of viral RNA synthesis. Some effect on blood sugar levels also was observed with several rhodanines.
