Effect of compounds 4a and 4d on Jurkat and THP-1 cell apoptosis. Cells were incubated with each compound at 2.5, 5 and 10 µM for 24 h. The level of apoptosis was assessed by flow cytometry using the Annexin V-FITC-PI staining. Data are representative of three experiments. * p < 0.05 and ** p < 0.01, compared with the control group.
