medium (NDM) and Dulbecco's modified Eagle's medium (DMEM) was evaluated against a human pancreatic cancer cell line PANC-1. Among the tested compounds, the 4'-hydroxy derivative 3d showed the most potent cytotoxicity in NDM (PC50 1.68μM) although the moderate preferential cytotoxicity (PC50 1.68μM in NDM vs PC50 20μM in DMEM). The 3'-hydroxy derivative 3e exhibited the most preferential cytotoxicity
