Biological Activity

Description Topotecan(NSC609699,Nogitecan,SKFS 104864A) is an antineoplastic agent used to treat ovarian cancer that works by inhibiting DNA topoisomerases.
Targets
Topo I [1]
In vitro
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]
Cell Research Cell lines LC-T2A-GFP lines
Concentrations 1 μM
Incubation Time 72 h
Method

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.
In Vivo
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]

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

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.
