Product Description
FUBP1-IN-1 is a potent FUBP1 inhibitor that interferes with the binding of FUBP1 to the FUSE sequence of single-stranded target DNA, with IC50 of 11.0 μM.
FUBP1–IN-1 (CAS: 883003-62-1) is a potent inhibitor of FUSE binding protein 1 (FUBP1). With a molecular formula of C19H14F3N3O2S and a molecular weight of 405.39 g/mol, it is a research compound. It interferes with the binding of FUBP1 to its single-strand target DNA FUSE sequence, with an IC50 of 11.0 µM.
Biological Activity I Assay Protocols (From Reference)
Targets
FUBP1–IN-1 targets FUSE binding protein 1 (FUBP1), a protein that binds to the far upstream element (FUSE) sequence of the c-myc gene. By inhibiting FUBP1, it disrupts the regulation of c-myc expression. This makes it a valuable tool for studying the role of FUBP1 in cell proliferation, differentiation, and cancer.
ln Vitro
In vitro, FUBP1–IN-1 demonstrates potent inhibition of FUBP1 binding to DNA. Its IC50 of 11.0 µM confirms its activity as a moderate inhibitor. This activity is confirmed in DNA binding assays where it inhibits the interaction between FUBP1 and the FUSE sequence. It is used to study the role of FUBP1 in c-myc regulation.
ln Vivo
In vivo, FUBP1–IN-1 is used as a research tool to study the role of FUBP1 in various physiological and pathological processes. By inhibiting FUBP1, it can affect the expression of c-myc and other target genes. It is used to explore the therapeutic potential of FUBP1 inhibition in cancer, where c-myc is often dysregulated.
Enzyme Assay
The in vitro DNA binding assay for FUBP1–IN-1 involves measuring its ability to inhibit the binding of FUBP1 to the FUSE sequence. Recombinant FUBP1 protein is incubated with a labeled FUSE DNA probe in the presence of varying concentrations of the compound. The amount of protein-DNA complex formed is measured using an electrophoretic mobility shift assay (EMSA) or a fluorescence polarization assay, and the IC50 is calculated.
Cell Assay
In vitro cell culture studies for FUBP1–IN-1 utilize cancer cell lines where c-myc is overexpressed. Cells are treated with the compound, and cell viability is assessed using MTT assays. The expression of c-myc and its target genes is measured by qPCR or Western blotting. The effect on cell proliferation and apoptosis is assessed by flow cytometry.
Animal Protocol
In vivo animal experiments for FUBP1–IN-1 are not extensively documented. However, its effects on c-myc expression and tumor growth could be studied in xenograft models. The compound would be administered, and tumor growth would be monitored. The expression of c-myc and other markers in the tumor tissue would be analyzed.
ADME/Pharmacokinetics
FUBP1–IN-1 has a molecular formula of C19H14F3N3O2S and a molecular weight of 405.39 g/mol. It is a solid compound that is soluble in DMSO (16.67 mg/mL, 41.12 mM). It is typically stored as a powder at -20°C for long-term stability. Its stability is maintained under recommended storage conditions. It has a predicted density of 1.42±0.1 g/cm3.
Toxicity/Toxicokinetics
Toxicological data for FUBP1–IN-1 are limited, as it is a research compound. It is not intended for human use. Comprehensive toxicity studies have not been reported. Standard safety precautions for handling chemical reagents should be followed. Its effects on c-myc expression suggest it could have significant biological effects.

Solubility (In Vivo)
Solubility in Formulation 1: ≥ 1.79 mg/mL (4.42 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 17.9 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.

 (Please use freshly prepared in vivo formulations for optimal results.)

5 mM 0.4934 mL 2.4668 mL 4.9335 mL
10 mM 0.2467 mL 1.2334 mL 2.4668 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
