Rosmarinic acid was reacted with nitrite ions under acidic conditions to give 6'-nitro- and 6',6''-dinitrorosmarinic acids according to the reaction time. Both compounds were active as HIV-1 integrase inhibitors at the submicromolar level. They also inhibited the viral replication in MT-4 cells with modest and similar selectivity indexes. The nitration of rosmarinic acid strongly improves the anti-integrase inhibition and the Antiviral activity without increasing the cellular toxicity.
