  • a 50% effective concentration required to prevent syncytia formation in HIV-1(IIIB)-infected C8166 cell cultures at day 3 after infection.

  • b 50% effective concentration required to prevent syncytia formation in HIV-1(IIIB)-exposed Raji/DC-SIGN cell cultures that were cocultivated with uninfected C8166 cells in the continuing presence of different concentrations of the test compounds.

  • c 50% effective concentration required to prevent syncytia formation in test compound-pre-exposed HIV-1(IIIB)-infected Raji/DC-SIGN cell cultures, cocultivated with uninfected C8166 cells in the absence of the test compounds.
