Bar charts showing IC₅₀ and SI values of MAA, MAX, and camptothecin (CPT). IC₅₀ (concentration that reduces cell viability to 50%) values were determined from the dose response curve generated by the MTT assay. SI (Selectivity index) values were determined by dividing the IC₅₀ value of MRC 5 with the IC₅₀ value of Ca Ski. Data for IC₅₀ were means ± S.E. calculated from three experiments.
