Cytotoxic activity-guided fractionation studies on Glycyrrhiza echinata roots led to the isolation of eight compounds (1-8). Chemical structures of the isolates were identified by NMR and MS analysis. Among the tested molecules, retrochalcones namely echinatin (3) (IC50=23.45-41.83 mu M), licochalcone B (4) (IC50=36.04-39.53 mu M) and tetrahydroxylmethoxychalcone (5) (IC50=7.09-80.81 mu M) were the most active ones against PC3, MCF7 and HepG2 cells. Moreover, 5 exhibited selectivity on prostate cancer cells (SI: 5.19). Hoechst staining and Annexin V/PI binding assays as well as cell cycle analysis on the compounds 3 (23 mu M) and 5 (5 and 7 mu M) demonstrated that these retrochalcones induced apoptosis and significantly suppressed cell cycle in G(1) and G(2)/M phases. Furthermore, 3 and 5 showed antimigratory effects on PC3 cells by wound healing assay. The results indicated that tested retrochalcones most particularly 5 could be potential anticancer drug candidates that prevent proliferation and migration of cancer cells.
