	5.17 μM	15.8 μM

In vitro
In vitro	The combination of gefitinib and irinotecan has a significant synergistic effect on the proliferation and migration of MDA-MB-231 cells.^[2]
Cell Research	Cell lines	Human BC cell lines
	Concentrations	32 μM
	Incubation Time	24 h, 72 h
	Method	Cells are seeded in 96-well plates at 6 × 103 cells/well for overnight incubation. The cells are exposed to irinotecan alone or combinations. Seventy-two hours after drug treatment, cell viability is tested with the MTT assay. For wound fealing assay, cells are seeded in 6-well culture plates at a density of 3 × 10⁵ cells/mL. After growing to confluence, cells are treated with irinotecan for 48 h in DMEM.

In Vivo
In vivo	The combination of gefitinib and irinotecan has a significant synergistic effect in the treatment of TNBC subtype cells in xenograft model.^[2]

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
