Salcaprozate sodium
Based on 4 publication(s) in Google Scholar
Salcaprozate sodium (SNAC), an oral absorption promoter, and has the potential as a delivery agent for oral forms of heparin and insulin. Salcaprozate sodium could increase passive transcellular permeation across small intestinal epithelia based on increased lipophilicity arising from non-covalent macromolecule complexation.

Biological Activity
SNAC (12.5-400 μg/mL; 24 h) has no toxicity to Caco-2 cells, and the survival percentage is above 90% when SNAC is 200 μg/mL[3].
SNAC (50 and 200 μg/mL) improves the apparent permeability coeffcient (Papp) of RA and SA-B by 2.14-fold and 3.68-fold compared with the Papp of SAs solution[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
SNAC (2000 mg/kg/d; oral gavage for 13 weeks) related mortality is evident only at the 2000-mg/kg/d level, 20% among males and 50% among females; no clear cause of death is evident[1].
SNAC (100-1000 mg/kg/d; oral gavage for 13 weeks) induces no mortality in the Wistar rat study at doses up to 1000 mg/kg/d[1].

Solvent & Solubility
H2O : 100 mg/mL (331.88 mM; Need ultrasonic)
DMSO : 50 mg/mL (165.94 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (8.30 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (8.30 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
