Mitochondrial depolarization (JC-1) levels in flow cytometry of IC₅₀ concentrations of Cl-amidine and carmustine in U-87 MG cells (control: 0.1% DMSO, n = 3, mean ± standard deviation).

Groups	Viable cells % (upper quadrant)	JC-1-positive cells % (lower quadrant)
Control	87.7 ± 2.0	12.3 ± 2.0
Cl-amidine	45.3 ± 11.51	54.7 ± 11.60
Carmustine	41.4 ± 3.80	58.6 ± 3.80

Cl-amidine = chlorine-amidine, DMSO = dimethyl sulfoxide, IC₅₀ = half maximal inhibitory concentration, JC-1 = 5,5', 6,6'-tetrachloro-1,1', 3,3' tetraethyl benzimidazolyl carbocyanine iodide, U-87 MG = human glioblastoma cells.
