体内（毎回新しく調製した物を用意してください）

Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。	2.100mg/ml (4.98mM)	Taking the 1 mL working solution as an example, add 50 μL of 42 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.
Clear solution	5% DMSO 1 95% Corn oil この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。	0.150mg/ml (0.36mM)	Taking the 1 mL working solution as an example, add 50 μL of 3 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明	Topotecan(NSC609699,Nogitecan,SKFS 104864A) is an antineoplastic agent used to treat ovarian cancer that works by inhibiting DNA topoisomerases.
in vitro	Topotecan exhibits inhibition of outgrowth of the highly invasive and migratory leader cells (LC) population, however, topotecan enrichs the LC subset 20% above the untreated control level.^[2]
in vivo	Topotecan (TPT), at least in part by inhibiting expression of Fli-1, significantly ameliorates lupus nephritis in NZBWF1 mice as effectively or better than cyclophosphamide (CYC).^[3]

細胞アッセイ	細胞株	LC-T2A-GFP lines
	濃度	1 μM
	反応時間	72 h
	実験の流れ	LC-T2A-GFP lines are seeded at 1200 cells per well of a 384-well plate, adhered overnight, and treated with chemotherapeutics olaparib, rucaparib, paclitaxel, topotecan, carboplatin, cyclophosphamide, cisplatin, and doxorubicin at empirically determined clinically relevant doses (1 μM). Cells are maintained at 37 ℃ with 5% CO₂ in treatment for 72 h. Four focal areas per replicate well were imaged using 4X magnification on a bright field.
