| Targets |
VGlut and vesicular monoamine transporter (VMAT) inhibitor; also interacts with various enzymes and cellular components
|
|---|---|
| ln Vitro |
Rose bengal shows direct cytotoxic effects on microorganisms and cancer cells in vitro. It inhibits VGlut and VMAT transporters. It also affects ATPases of plasma membranes.
|
| ln Vivo |
In vivo, rose bengal has been studied for antitumor activity via intralesional injections. It is being investigated in clinical trials as an injectable formulation (PV-10) for melanoma, breast cancer, and skin conditions including eczema and psoriasis. Oral administration in mice induced thyroid tumors.
|
| Enzyme Assay |
Enzyme inhibition assays are performed using purified enzymes or membrane preparations. For VMAT inhibition, synaptic vesicles are incubated with [³H]-serotonin or [³H]-dopamine and varying concentrations of rose bengal. For ATPase studies, plasma membranes are incubated with ATP and the compound, and phosphate release is measured.
|
| Cell Assay |
Cancer cell lines (e.g., melanoma, breast cancer) are cultured and treated with rose bengal. Cytotoxicity is assessed via MTT or similar assays. Cell death mechanisms are evaluated by apoptosis and necrosis assays.
|
| Animal Protocol |
In animal models, rose bengal is administered intralesionally or orally. Tumor growth inhibition is monitored. In rodent studies, oral administration for 19 weeks caused changes in liver and thyroid weights.

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).

Oral Formulation 3: Dissolved in PEG400 (Please use freshly prepared in vivo formulations for optimal results.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 0.9525 mL | 4.7626 mL | 9.5252 mL | |
| 5 mM | 0.1905 mL | 0.9525 mL | 1.9050 mL | |
| 10 mM | 0.0953 mL | 0.4763 mL | 0.9525 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.
