The effect of 6-azauridine, an inhibitor of RNA synthesis, has been shown by 2 experimental methods to inhibit the replication of measles virus within mammalian cells in vitro. In a direct virus titration in which the drug was incorporated in the agar overlay, 6-AZ not only reduced the infectivity of measles virus but also delayed plaque development. Experiments designed to test the effectiveness of 6-azauridine when added to cultures at intervals after infection, showed that this uridine analog was capable of reducing the amount of infectious virus produced by each infected cell, and that the drug is more effective when added early in the infection cycle.
