UPGL00004 (UPGL-00004) is a newly developed glutaminase C (GAC, kidney glutaminase isoform C) inhibitor that is strong, allosteric, and has anticancer properties. With an IC50 of 29 nM, UPGL00004 exhibits high selectivity for GAC over GLS2. It also inhibits GAC. With low nanomolar potency, UPGL00004 can inhibit both the enzymatic activity of GAC and the proliferation of highly aggressive triple negative MDA-MB-231 breast cancer cells. When UPGL00004 and its analogs are contrasted with the top GAC inhibitors, BPTES and CB-839, they exhibit better microsomal stability, ligand efficiency, and fewer rotatable bonds. Heteroatom substituted heterocycloalkanes were used to replace the flexible n-diethylthio or n-butyl moiety found in the leading inhibitors in order to improve their properties. Cancer cells have altered glycolytic flux (the "Warburg effect"), which makes them dependent on increased glutamine metabolism (also known as "glutamine addiction") for growth. Overexpression of glutaminase C (GAC), which catalyzes the initial step in glutamine metabolism and thus represents a potential therapeutic target, satisfies this requirement.

| Cell Assay |
Breast cancer cells are kept at 37°C and in an atmosphere with 5% CO2 in complete media (RPMI 1640 supplemented with 10% FBS). For assays, a density of 1 × 10⁴ cells per well is applied to the wells of a 12-well plate. After allowing the cells to adhere to the plate for one night, they are treated for six days in full media with the prescribed dosages of each medication or a DMSO control. Every two days, drugs and media are updated. Trypsin is used to extract the cells from the plates on the sixth day, and a hemocytometer is used to manually count the cells.

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 1.8703 mL | 9.3517 mL | 18.7035 mL | |
| 5 mM | 0.3741 mL | 1.8703 mL | 3.7407 mL | |
| 10 mM | 0.1870 mL | 0.9352 mL | 1.8703 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.
