ATPR inhibits cell proliferation in human NB4 and THP-1 cells. a, b Dose- and time-dependent effects of ATPR on NB4 and THP-1 cells. NB4 and THP-1 cells were exposed to various concentrations (0, 10−9, 10−8, 10−7, 10−6, or 10−5 M) of ATPR for 24–72 h, followed by the determination of cell viability using the CCK8 assay. Values are presented as the mean ± SD of three independent experiments. *p < 0.05, **p < 0.01 versus control group
