Absorption, Distribution and Excretion
Following topical application, mafenib can be absorbed into the systemic circulation through areas with poor vascular distribution. Renal Metabolites: Metabolites are rapidly excreted in high concentrations in the urine; however, the parent compound has not been detected in urine. Metabolism/Metabolites Metabolized to a carbonic anhydrase inhibitor. |

| Additional Infomation |
Mafenide is an aromatic amine. Mafenide is a sulfonamide antibacterial agent used to treat severe burns. It promotes healing of deep burns by reducing the number of bacteria in burned tissue. In 1998, Mafenide acetate was approved under the FDA's accelerated approval program. In November 2022, the FDA withdrew the approval of Mafenide acetate (5% topical solution powder) because an incomplete confirmatory study failed to meet the requirements for accelerated approval. Mafenide is a methylated sulfonamide antibacterial agent. It is a sulfonamide drug that inhibits carbonic anhydrase and is used as a topical antibacterial agent, particularly for the treatment of burns. See also: Mafenide acetate (in salt form). Mafenib hydrochloride (in salt form).
Drug Indications Indicated as an adjunct topical antibacterial agent to control bacterial infection when covering a wet dressing on an autologous mesh graft after excision of a burn wound. FDA Label Mechanism of Action The exact mechanism of action of masfennig is not yet clear. However, masfennig can reduce the number of bacteria in avascular burn tissue and promote the self-healing of deep burns. |

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 | 5.3697 mL | 26.8485 mL | 53.6970 mL | |
| 5 mM | 1.0739 mL | 5.3697 mL | 10.7394 mL | |
| 10 mM | 0.5370 mL | 2.6849 mL | 5.3697 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.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
