PROBLEM TO BE SOLVED: To provide a new hydroxycoumarin derivative having antiviral action to HIV-1 virus and useful as an antiviral agent. SOLUTION: This new hydroxycoumarin derivative is represented by the general formula (R1 is 4,7-dihydroxycoumarinyl group or 4,5,7- trihydroxycoumarinyl group) and is e.g. 3,3-(4-carboxybenzylidene)-bis(4,7- dihydroxycoumarin). The exemplified compound can be obtained by reacting 4,7-dihydroxycoumarin with terephthalaldehyde. The antiviral agent to HIV virus contains the new hydroxycoumarin derivative as an active component.
