Figure 5From: Synthesis and biological evaluation of Combretastatin A-4 derivatives containing a 3’-O-substituted carbonic ether moiety as potential antitumor agentsApoptotic effect on MCF-7 cell line induced by CA-4E. MFC-7 cells were incubated in media containing various concentrations of CA-4E (i.e., 0, 1.5, 3 and 6 nM) for 24 h. (A) Apoptotic cell scatter plots were constructed by flow cytometry using FITV-Annexin V/PI staining. (B) Rate of apoptotic cells at different concentrations of CA-4E.Back to article page
