摘要:
New antiviral agent U-50,228 and derivatives thereof, produced by the controlled fermentation of the known microorganism Streptomyces platensis var. clarensis var nova, NRRL 8035. This antiviral agent and its derivatives are active against DNA-viruses, for example, the Herpes virus and, thus, can be used to control such virus where its presence is not desired. For example, U-50,228 and its derivatives can be used to swab laboratory benches and equipment in a virology laboratory to eliminate the presence of Herpes virus.
