Antiproliferation effects of benzimidazoisoquinoline derivatives in human glioblastoma cells. Chemical structures of the synthetic benzimidazoisoquinoline derivatives were labeled by compounds 1A–I. IC₅₀ values were also obtained after 48 h with treatment of compounds 1A–I at concentrations of 3.125–50 μmol/L in U87 and LN229 cells and represented as percentage of control as mean ± SD of experiments performed at least three times
