Figure 5.
Panels A-C: Dose-dependent effects of compounds 1 and 29-31 on renilla luciferase expressed by rPIV5-RL in HeLa cells (Panel A), on viability of HeLa cells after 24 h (Panel B), and on viability of NHBE cells after 40 h (Panel C). Viability of mammalian cells was measured by quantification of cellular ATP with firefly luciferase. Panel D: Examination of effects of compounds (0.5 μM) compared with Triton X-100 (1%) on replication of intracellular M. fortuitum bacteria in HeLa cells. Data are in triplicate or larger numbers of measurements. Standard errors of the mean are ≤ 20%.
