ABSTRACT
Background:
Many current anti-cancer drugs used to treat breast cancer mediate tumor cell death through the induction of apoptosis. Cancer cells, however, often acquire multidrug-resistance following prolonged exposure to chemotherapeutics. Consequently, molecular pathways involved in tumor cell proliferation have become potential targets for pharmacological intervention. Ceramides are tumor suppressor lipids naturally found in the cell membrane, and are central molecules in the sphingolipid signalling pathway.Methods:
Our lab has targeted the ceramide signaling pathway for potential pharmacological intervention in the treatment of breast cancer. Previously, we have shown that certain ceramide analogs have therapeutic potential in the treatment of chemo-sensitive and multidrug-resistant breast cancers. Using the most active analog from our previous studies as the lead compound, new analogs containing a flavone moiety were designed and synthesized. In general, flavone derivatives often show interesting pharmacological properties, and compounds based on these molecules have been found useful in many different therapeutic areas including anti-tumor, anti-coagulants, and anti-HIV therapy.Results:
Synthesis and biological evaluation of five new flavonoid ceramide analogs are reported here. These compounds were also shown to be self-fluorescent, which can be useful when investigating their distribution and action in cancer cells.Conclusion:
Four out of the five flavone ceramide analogs in this study showed significant anti-proliferation activities in the three cell lines studied, MDA-MB-232, MCF-7, and MCF-7TN-R; some showing varying degrees of selectivity. The mechanisms involved in cell proliferation inhibition are complicated and further studies are needed.
