Table 1.

IC50 values of DNR, Fe3O4, and Fe3O4 plus DNR according to the MTT assafys

treatment type IC50 values
K562 cells KA cells
Fe3O4 (mg/L) 3.30±0.25 3.25±0.30
DNR (mol/L) 7.94±0.76×10−6 39.72±2.95×10−6
Fe3O4+DNR (mg/L+mol/L) 0.58 + 3.95×10−6 0.58 + 3.18×10−6

The values are shown as mean±SD, n = 5.

Note: IC50 values indicate the 50% growth inhibitory concentration values of DNR, Fe3O4, and Fe3O4 plus DNR.
