Table 1. GI₅₀ of STF-62247 in leukemic cell lines.

Cell line	24 h	48 h	72 h	96 h
S1T	43.0	29.3	21.2	14.9
MT-2	42.9	15.1	7.62	6.43
Jurkat	83.9	37.6	27.9	19.3

Cell lines were incubated at 2 × 10⁵ cells/mL in the presence of indicated concentrations (μM) of STF-62247 for 24–96 h. Values of GI₅₀ (compound concentration that reduced cell growth by 50%) are shown for various time points.
