Ribonucleotide reductase inhibitors enhance the anti-HIV-1 activities of a variety of nucleoside analogs, including those that act as chain terminators and those that increase the HIV-1 mutation rate. However the use of these ribonucleotide reductase inhibitors is limited by their associated toxicities. The hydroxylated phytostilbene resveratrol has activity in a host of systems including inhibition of ribonucleotide reductase and has minimal toxicity. Here we synthesized derivatives of resveratrol and examined them for anti-HIV-1 activity and their ability to enhance the antiviral activity of decitabine, a nucleoside analog that decreases viral replication by increasing the HIV-1 mutation rate. The data demonstrates that six of the derivatives have anti-HIV-1 activity greater than resveratrol. However, only resveratrol acted in synergy with decitabine to inhibit HIV-1 infectivity. These results reveal novel resveratrol derivatives with anti-HIV-1 activity that may have mechanisms of action that differ from the drugs currently used to treat HIV-1. (C) 2012 Elsevier Ltd.
