Biological Activity
| ln Vitro | In a dose-dependent way, CAIX Inhibitor S4 (1-100 μM; 24 h) reduces the growth of MDA-MB-231, HCT116, and HT29 cells [1]. Under hypoxic conditions, eGFP-MDA-MB-231 cell migration is inhibited in a concentration-dependent manner by CAIX Inhibitor S4 (3.3-33 μM; 24 h) [1]. Under hypoxic conditions, CAIX Inhibitor S4 (33 μM; 15-60 min) decreases the spreading of MDA-MB-231 cells; however, under normoxic conditions, there is minimal delay [1]. |
| ln Vivo | CAIX Inhibitor S4 (10 mg/kg; i.p. for 14 days) inhibits metastatic tumor burden in the MDA-MB-231 model without affecting primary tumor growth or mouse condition [1]. |
| Cell Assay |
Cell proliferation assay[1] Cell Types: MDA-MB-231, HCT116 and HT29 Cell Tested Concentrations: 1, 10, 100 μM Incubation Duration: 24 hrs (hours) Experimental Results: Inhibition of cell proliferation of MDA-MB-231, HCT116 and HT29 cells, IC50 481 μM, >1000 μM and 20 μM respectively. |
| Animal Protocol |
Animal/Disease Models: Female nu/nu CBA mice (10-12 weeks) are injected with eGFP-MDA-MB-231 cells [1] Doses: 10 mg/kg Route of Administration: intraperitoneal (ip) injection every day, "5 days, 2 days off" Results of the 14-day dosing regimen: Dramatically diminished metastatic tumor burden in the lungs of mice bearing orthotopic eGFP-MDA-MB-231 tumors. Average body weights were similar between vehicle and S4-treated mice throughout the experiments. |

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 (e.g. IP/IV/IM/SC) Injection Formulation 1: DMSO : Tween 80: Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline) *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)] *Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Injection Formulation 5: 2-Hydroxypropyl-β-cyclodextrin : Saline = 50 : 50 (i.e. 500 μL 2-Hydroxypropyl-β-cyclodextrin → 500 μL Saline) Injection Formulation 6: DMSO : PEG300 : castor oil : Saline = 5 : 10 : 20 : 65 (i.e. 50 μL DMSO → 100 μLPEG300 → 200 μL castor oil → 650 μL Saline) Injection Formulation 7: Ethanol : Cremophor : Saline = 10: 10 : 80 (i.e. 100 μL Ethanol → 100 μL Cremophor → 800 μL Saline) Injection Formulation 8: Dissolve in Cremophor/Ethanol (50 : 50), then diluted by Saline Injection Formulation 9: EtOH : Corn oil = 10 : 90 (i.e. 100 μL EtOH → 900 μL Corn oil) Injection Formulation 10: EtOH : PEG300:Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL EtOH → 400 μLPEG300 → 50 μL Tween 80 → 450 μL 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). Oral Formulation 3: Dissolved in PEG400 Oral Formulation 4: Suspend in 0.2% Carboxymethyl cellulose Oral Formulation 5: Dissolve in 0.25% Tween 80 and 0.5% Carboxymethyl cellulose Oral Formulation 6: Mixing with food powders Note: Please be aware that the above formulations are for reference only. InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently.  (Please use freshly prepared in vivo formulations for optimal results.) |
