[3H]AA-labeled human lung macrophages were preincubated (30 min, 37°C) with increasing concentrations (0.01–10 μM) of AZ-1 (○), pyrrolidine-1 (●) or Me-Indoxam (■) and then stimulated with 1 μM PMA (10 min, 37°C) and subsequently with 1 μM A23187 (30 min, 37°C). At the of the incubation, supernatants were collected and centrifuged twice (1000 g, 4°C, 5 min) for subsequent determination of AA release. Values are the mean ± SE of three different experiments.
* p < 0.05 vs. PMA + A23187
** p < 0.01 vs. PMA + A23187
