Biological Activity

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.
Targets
CAXII [1]
(Cell-free assay)		 CAIX [1]
(Cell-free assay)
4.5 nM(Ki) 45.1 nM(Ki)
In vitro U-104 (50  μM) blocks the mesenchymal phenotype in the cancer stem cells population in hypoxia condition of 4T1 cells. This compound (<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] This chemical possesses aromatic groups at the second nitrogen ureido group. [3]
In vivo U-104 (38 mg/kg) inhibits primary tumor growth in the mice implanted orthotopically with MDA-MB-231 LM2-4Luc+ cells. This compound (19 mg/kg) inhibits metastases formation in the 4T1 experimental metastasis mice model. [1] This chemical (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. It (5 mg/mL, oral gavage) shows a significant delay in tumor growth in Balb/c mice orthotopically implanted with 4T1 cells. [2]

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.

Synchronous with the decrease in CA9 expression, the TMZ + U‑104 combination substantially decreased the expression of SOX9, p-AKT and BCL‑2 in glioma cells, and increased the expression of BAX, compared to the TMZ alone group.
