title: HIV integrase inhibitors with nucleobase scaffolds: discovery of a highly potent anti-HIV agent.
abstract: HIV integrase is essential for HIV replication. However, there are currently no integrase inhibitors in clinical use for AIDS. We have discovered a conceptually new beta-diketo acid that is a powerful inhibitor of both the 3'-processing and strand transfer steps of HIV-1 integrase. The in vitro anti-HIV data of this inhibitor were remarkable as exemplified by its highly potent antiviral therapeutic efficacy against HIV(TEKI) and HIV-1(NL4)(-)(3) replication in PBMC (TI >4,000 and >10,000, respectively).
