RESUMEN
A series of cycloberberine derivatives were designed, synthesized and evaluated for their anti-cancer activities in vitro. Among these analogs, compounds 6c, 6e and 6g showed strong inhibition on human HepG2 cells. They afforded a potent effect against DOX-resistant MCF-7 breast cells as well. The primary mechanism showed that cell cycle was blocked at G2/M phase of HepG2 cells treated with 6g using flow cytometry assay. It significantly inhibited the activity of DNA Top I at the concentration of 0.1 mg mL-1. Our results provided a basis for the development of this kind of compounds as novel anti-cancer agents.

A series of novel N-(2-arylethyl) isoquinoline derivatives were designed, synthesized and evaluated for their anti-cancer activities. Among these analogs, compound 9a exhibited the potential anti-cancer activities on HepG2 and HCT116 cells with IC50 values of 2.52 and 1.99 microg x mL(-1), respectively. Cell cycle was blocked at S phase of HepG2 cells treated with 9a by flow cytometry detection. Our results provided a basis for the development of a new series of anti-cancer candidates.
