Toxicity of diterpenes (1–4) (panel-A) and AMB (panel-B) in THP-1 monocytes. Cell viability was measured using almar blue as described in the methods section. Data points are mean and SEM values obtained from six replicates. For symbols: see Fig. 3. In the AMB treatment group (panel-B), * and ** represent significant differences (unpaired t-test) compared to untreated control group at the level of p = 0.05 and p = 0.01 respectively.
