-D-glucopyranoside
Shionogi Research Laboratory Shionogi & Co., Ltd. Fukushima-ku, Osaka 553, Japan
The antiviral activity of phenyl-6-chloro-6-deoxy-
-D-glucopyranoside (PCG) was studied. PCG specifically inhibited the growth of paramyxoviruses including Sendai, measles and Newcastle disease viruses in LLCMK2 cells at a concentration of 0.5 to 1.0 mM, but did not restrict the multiplication of other RNA viruses (influenza, vesicular stomatitis and polio viruses) at these concentrations.
PCG might act in the late stage during virus replication of Sendai virus as it did not inhibit virus RNA and protein synthesis in the infected cells. Comparative studies on the biological properties of virus particles grown in the presence and absence of PCG demonstrated that treatment with it caused the formation of non-haemagglutinating particles.
