Darinaparsin (DAR) is more potent than As2O3 at inducing growth inhibition and apoptosis in NB4, AR2, IM9 and CCRF-CEM cells. Cells were treated with DAR or As2O3 as indicated for 48 h. (a) Cell viability was evaluated using Trypan blue exclusion. Each bar represents an average of three independent samples, and standard deviation bars are shown. Asterisks indicate significant differences from As2O3-treated cells (*P=0.05; **P=0.01; ***P=0.001).

The authors apologize for any inconvenience caused.
