Description and Uses
THI (94944-70-4) was identified as a biologically active impurity in caramel food coloring.1 It is a potent inhibitor of sphingosine-1-phosphate (S1P) lyase.2 It disrupts lymphocyte egress from lymphoid tissue by interfering with S1P gradients.3,4 The novel immunomodulatory activity of THI and its biochemical mechanism may represent a new target for the development of new generation of immunosuppressants.5
Sphingosine-1-phosphate (S1P) lyase catalyzes the irreversible decomposition of S1P to hexadecanaldehyde and phosphoethanolamine. 2-Acetyl-5-tetrahydroxybutyl imidazole (THI) is an inhibitor of S1P lyase. Because S1P lyase is primarily expressed in lymphatic tissue, treatment of mice with THI (50 μg/ml in drinking water) increases lymphoid tissue S1P concentrations 100-fold, reducing lymphocyte egress from thymus and peripheral lymphoid organs. The resulting lymphopenia is reversible following cessation of THI treatment. Reducing S1P lyase activity results in therapeutic levels of immunosuppression without the non-lymphoid lesions that result from synthetic S1P receptor agonists.
