(15) showed significant cytotoxicities. The most effective compound was 15, which showed high cytotoxic activity with an IC50 value lower than 1 μg/ml, and no selectivity on the tumor cells evaluated. Substituents at C(4) of ring B were found to be essential for cytotoxicity. In addition, it was also demonstrated that some of these chalcones are moderate inhibitors of cathepsinK and have no activity

against five cancer cell lines. Such hybrid derivatives demonstrated significantly increased anti-tumor activity compared with the corresponding amino chalcones. The most promising lead molecules were 1k, 1m and 2j, which had the highest activity toward the five cell lines. Flow cytometry with K562 cells showed that the most active compounds resulted in a large proportion of the cells entering in the apoptotic
