1-Benzyl-2-methyl-3-indolylmethylene thiobarbiturate compounds induce apoptosis in mutant NPM1 expressing leukemia cells: A. OCI-AML3 cells were treated with the indicated concentrations of 1-benzyl-2-methyl-3-indolylmethylene thiobarbiturate compounds (7i, 7j, 7k, and 7l) and YTR-107 (1) for 48 hr. B. OCI-AML3 cells were treated with the indicated concentrations of compound 7k for 48 hr. C. OCI-AML3 cells were treated with the indicated concentrations of compound 7l for 48 hr. After the indicated incubation time period, cells were stained with annexin V and TO-PRO 3 and the percentages of apoptotic cells were measured by flow cytometry. Columns represent the mean of 3 independent experiments; bars represent the SEM.
