Biological Activity
| ln Vitro | In a concentration-dependent manner, KB-5492 (0.001-100 μM) inhibits selective [3H]DTG binding [1]. The increase in 51Cr release from gastric epithelial cells generated by ethanol and acidified aspirin was considerably and concentration-dependently inhibited by KB-5492 (0.1-1 mM) [2]. |
| ln Vivo | KB-5492 (200 mg/kg; oral) inhibits the stomach mucosa from developing macroscopic lesions [2]. |
| Animal Protocol |
Animal/Disease Models: Male SD (SD (Sprague-Dawley)) rats, body weight 210-240 g, induced gastric mucosal damage [2] Doses: 200 mg/kg Route of Administration: po (oral gavage) Experimental Results: Compared with the control, the lesion length was shortened. Prevent deep mucosal lesions and surface epithelial cell shedding. |

Solubility Data
| Solubility (In Vitro) | DMSO : ~250 mg/mL (~457.40 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (3.81 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 3: ≥ 2.08 mg/mL (3.81 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. 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. Solubility in Formulation 4: ≥ 2.08 mg/mL (3.81 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution.

Solubility in Formulation 5: ≥ 2.08 mg/mL (3.81 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. Solubility in Formulation 6: ≥ 2.08 mg/mL (3.81 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
