(c-f) Effects of the CAIX inhibitor U-104 (75 μM) on cell proliferation by Pt45.P1/asTF+ cells (c, e) or Pt45.P1 cells (d, f) under advanced-stage (c, d) or early-stage conditions (e, f). At the indicated times, WST-1 uptake was measured by colorimetry. The error bars are s.e.m. * Indicates significance at P<0.05.

Regression coefficients from the second-order stepwise linear regression model are provided based on the data obtained from Search 2.1 (B) The results allow the least effective compounds to be eliminated. Red is used to highlighted drug contributions that do not help to inhibit cell viability, orange bars are used to indicate minimal contributions and green highlights synergistic drug interactions. The inset in B shows the linear fit of modelled data with theoretical quartiles versus standardized residuals and the corresponding R2-values for each model. Significance is indicated by asterisks, **p < 0.01 and *p < 0.05.

|Description||U-104 (MST-104, NSC 213841, SLC-0111, WBI-5111) is a potent carbonic anhydrase (CA) inhibitor for CA IX and CA XII with Ki of 45.1 nM and 4.5 nM, respectively, very low inhibition for CA I and CA II.|
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.  U-104 possesses aromatic groups at the second nitrogen ureido group. 
|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.  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. |
|In vitro||DMSO||62 mg/mL (200.43 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
30% PEG400+0.5% Tween80+5% propylene glycol
For best results, use promptly after mixing.
* 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.

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
