摘要：
A novel heterocyclic derivative of formula (I): ##STR1## wherein R.sub.1 represents ##STR2## and R.sub.2 represents hydrogen or acyl. When R.sub.2 is acyl, the derivative can be prepared, for example, by the following process: ##STR3## wherein R.sub.4 is acyl and R.sub.1 is ##STR4## The derivative is less toxic and has radiosensitizing activity and antiviral activity even at a low concentration.Radiosensitizing agents and antiviral agents containing the derivative as active component are also disclosed.
