| Biochem/physiol Actions: |
2-Acetyl-4-tetrahydroxybutyl imidazole (THI) is known to induce peripheral blood lymphopenia in rats. Studies in rats have also reported that THI can affect lymphocyte migration and degradation. |
| Biochem/physiol Actions: |
THI is an inhibitor of sphingosine-1-phosphate lyase and acts as an immunosuppressant. Sphingosine-1-phosphate (S1P) lyase catalyzes the irreversible decomposition of S1P to hexadecanaldehyde and phosphoethanolamine. Reducing S1P lyase activity results in therapeutic levels of immunosuppression without the non-lymphoid lesions that result from synthetic S1P receptor agonists. |
| Packaging: |
1, 5, 25 mg in glass bottle |
| Preparation Note: |
THI is soluble in DMSO at a concentration that is greater than 5 mg/ml. |
