In vitro
In vitro U-104 (50  μM) blocks the mesenchymal phenotype in the cancer stem cells population in hypoxia condition of 4T1 cells. U-104 (<50  μM) significantly reduces migration in a dose-dependent manner in metastatic MDA-MB-231 LM2-4Luc+ cells , with cells growing as compact colonies similar to parental MDA-MB-231 cells. [2] U-104 possesses aromatic groups at the second nitrogen ureido group. [3]
In Vivo
In vivo U-104 (38 mg/kg) inhibits primary tumor growth in the mice implanted orthotopically with MDA-MB-231 LM2-4Luc+ cells. U-104 (19 mg/kg) inhibits metastases formation in the 4T1 experimental metastasis mice model. [1] U-104 (38 mg/kg) significantly delay primary tumor growth and reduces cancer stem cell population in NOD/SCID mice orthotopically implanted with MDA-MB-231 LM2-4Luc+ cells. U-104 (5 mg/mL, oral gavage) shows a significant delay in tumor growth in Balb/c mice orthotopically implanted with 4T1 cells. [2]

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.
