As2O3 and melarsoprol induce growth inhibition of the RA-resistant cell line NB4.306 cells. Concentrations of As2O3 (A, growth curve; C, viability) and melarsoprol (B, growth curve; D, viability) are the same as depicted in Fig 1. As2O3 and melarsoprol inhibit cell growth in a dose-dependent manner.
