Effect of new berberine derivatives on colon cancer cells

The natural alkaloid berberine has been recently described as a promising antlcancer arug. In oraer to improve its efficacy and bioavailability, several derivatives have been designed and synthesized and found to be even more potent than the lead compound. Among the series of berberine deriva- tives we have produced, five compounds were identified to be able to heavily affect the proliferation of human HCT116 and SW613-B3 colon carcinoma cell lines. Remarkably, these active compounds exhibit high fluorescence emission property and ability to induce autophagy.
