FIG. 1.
PPCM inhibits HIV infection in cell culture. TZM-bl cells were infected with 103 TCID50 of each of the indicated HIV-1 strains in the presence or absence of various concentrations of PPCM. Virus and drug were left in culture for 48 h at 37°C, and infectivity was monitored by a luciferase assay. Cell viability was determined by an MTT assay following exposure to drug for 48 h. Results are means ± standard errors of the means obtained from three experiments conducted in triplicate. RLU, relative luciferase units.
