The TUNEL assay of compound 3c in tumor cells. For MGC-803 group, A: negative control; B and C: treated with HCPT and BA (10 μM each) as positive for 48 h; D, E, and F: treated with compound 3c (5 μM) for 12 h, 24 h, and 48 h, respectively. For PC3 cells group, A’: negative control; B’ and C’: treated with HCPT and BA (10 μM each) as positive for 48 h; D’, E’, and F’: treated with compound 3c (5 μM) for 12 h, 24 h, and 48 h, respectively.
