excitingly, our studies of 5q in camptothecin (CCRF-CEM/C2) and mitoxantrone (HL-60/MX2) resistant cancer cells highlight its ability to selectively kill drug-resistant cells over parent cancer cells. 5q inhibits tumor cell growth through the induction of apoptosis, with detailed mechanism of its selectivity toward drug-resistant cancer cells under investigation. These results suggest that 5q is a promising

cytotoxicity in the NCI-60 panel of cell lines with an average IC50 of 1.04 μM. In addition, 5 has a unique mechanism of action in comparison with standard agents in the NCI database based on COMPARE analysis. Further structure–activityrelationship study led to the development of a more potent analogue, compound 7d, with an IC50 of 640 nM in HL60/MX2. Additionally, one enantiomer of 5 is 13-fold more active
