Determination of MPC-5 cell viability by MTT assay. (A) MPC-5 cells were treated by a series of concentrations of Adriamycin (from 6.25 × 10⁻² μM to 4 μM); (B) MPC-5 cells were treated by a series of concentrations of Luteolin (from 1.25 to 320 μM); (C) MPC-5 cells were treated by a series of concentrations of Wogonin (from 1.25 to 320 μM); (D) MPC-5 cells were treated by a series of concentrations of Formononetin (from 1.25 to 320 μM); (E) MPC-5 cells were treated by a series of concentrations of Calycosin (from 1.25 to 320 μM); (F) MPC-5 cells were treated by a series of concentrations of YQHXD (from 12.5 μg/ml to 3,200 μg/ml). After being incubated with adriamycin or compounds for 24 h, cell viability was detected by MTT method at 490 nm wavelength. ^** p < 0.01, ^* p < 0.05 vs. DMSO group.
