IC₅₀ of 8 EC cell lines.

Endometrial cell line	IC50 (μM), ±SE
Ishikawa	22.9 ± 3.62
MFE296	25.2 ± 6.46
RL95-2	28.9 ± 4.31
AN3CA	32.1 ± 6.70
KLE	127.4 ± 38.87
MFE280	321.2 ± 36.39

The 8 EC cell lines were seeded in 96-well plates at a density of 5–10 × 10³ cells per mL and incubated overnight at 37°C. Cells were subsequently treated with cisplatin for 72 hours, and cell viability was analyzed using MTS assay.
